Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) that permit reduced disclosure for interim periods. The condensed consolidated balance sheet as of December 31, 2016 was derived from audited financial statements, but does not include all necessary disclosures required by accounting principles generally accepted in the United States of America (“GAAP”). The unaudited condensed consolidated financial statements include all accounts of the Company and its subsidiaries and, in the opinion of management, include all recurring adjustments and normal accruals necessary for a fair statement of the Company’s financial position, results of operations and cash flows for the dates and periods presented. These unaudited financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 (“ 2016 Annual Report on Form 10-K”). Results for interim periods are not necessarily indicative of the results to be expected during the remainder of the current year or for any future period. All material intercompany accounts and transactions have been eliminated in consolidation. Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation. Comprehensive income Comprehensive income is equal to the net income for all periods presented. Recently adopted accounting pronouncements In July 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2015-11, Simplifying the Measurement of Inventory (“ASU 2015-11”). ASU 2015-11 requires that inventory within the scope of the guidance be measured at the lower of cost and net realizable value. Prior to the issuance of the standard, inventory was measured at the lower of cost or market, where market was defined as replacement cost, with a ceiling of net realizable value and floor of net realizable value less a normal profit margin. Inventory measured using last-in, first-out (LIFO) and the retail inventory method are not impacted by the new guidance. Prospective application is required and early adoption is permitted. ASU 2015-11 became effective for the Company’s annual and interim periods beginning on January 1, 2017. The adoption of the guidance did not have a material impact on our financial statements. Recently issued accounting pronouncements not yet adopted In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), and issued subsequent amendments to the initial guidance within Accounting Standards Update 2016-08, Revenue from Contracts with Customers, Principal versus Agent Considerations (“ASU 2016-08”) issued in March 2016, Accounting Standards Update 2016-10, Revenue from Contracts with Customers, Identifying Performance Obligations and Licensing (“ASU 2016-10”) issued in April 2016, Accounting Standards Update 2016-12, Revenue from Contracts with Customers, Narrow-Scope Improvements and Practical Expedients (“ASU 2016-12”) issued in May 2016 and Accounting Standards Update 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers (“ASU 2016-20”) issued in December 2016 (ASU 2014-09, ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20 collectively “Topic 606”). Topic 606 provides a comprehensive revenue recognition model requiring companies to recognize revenue for the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. In July 2015, the FASB voted to defer the effective date of ASU 2014-09 by one year, and therefore, the standard is effective for the Company’s annual and interim periods beginning on January 1, 2018. The guidance permits the use of either a full retrospective or modified retrospective transition method. We expect to adopt the standard on January 1, 2018 using the modified retrospective transition method, which recognizes the cumulative effect of initially applying the standard in retained earnings on the date of adoption, with the option to utilize certain practical expedients as defined in Topic 606. We are continuing to evaluate the impact of the standard on our financial statements, but based on our preliminary assessment, we believe that contracts with a service element may be impacted as we identify the promised goods and services (performance obligations) within our construction services contracts, which could impact the timing of revenue recognition. Currently, we expect the timing of revenue recognition for our building products contracts to be similar to the current timing. We also continue to evaluate the disclosure requirements of the standard, which are expected to be significant and incremental to the current disclosures. As we continue to evaluate the standard and finalize our assessment, our current conclusions are subject to change. In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases (“ASU 2016-02”). The new standard establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU 2016-02 is effective for the Company’s annual and interim periods beginning on January 1, 2019. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. We are in the process of evaluating the impact of the standard on our financial statements. As a lessee, certain of our various leases under existing guidance are classified as operating leases that are not recorded on the balance sheet but are recorded in the statement of operations as expense is incurred. Upon adoption of the standard, we will be required to record substantially all leases on the balance sheet as a ROU asset and a lease liability. The timing of expense recognition and classification in the statement of operations could change based on the classification of leases as either operating or financing. In August 2016, the FASB issued Accounting Standards Update 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 was issued to decrease the diversity in practice of how certain cash receipts and cash payments are presented and classified in the statement of cash flows by providing guidance on eight specific cash flow issues. ASU 2016-15 is effective for the Company’s annual and interim periods beginning on January 1, 2018, with early adoption permitted and retrospective application required. The adoption of the standard is not expected to have a material impact on our financial statements. In November 2016, the FASB issued Accounting Standards Update 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU 2016-18”). ASU 2016-18 requires that the statement of cash flows include restricted cash in the beginning and end-of-period total amounts shown and that the statement of cash flows explain the changes in restricted cash during the period. ASU 2016-18 is effective for the Company's annual and interim periods beginning on January 1, 2018. Retrospective application is required and early adoption is permitted. The adoption of the standard is not expected to have a material impact on our financial statements. In January 2017, the FASB issued Accounting Standards Update 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”). ASU 2017-01 provides guidance in determining when a set of assets and activities meets the definition of a business. ASU 2017-01 is effective for the Company's annual and interim periods beginning on January 1, 2018. Early application is permitted for transactions meeting certain criteria and prospective application is required. The adoption of the standard is not expected to have a material impact on our financial statements. In January 2017, the FASB issued Accounting Standards Update 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). ASU 2017-04 simplifies the accounting for goodwill impairment by removing Step 2 of the goodwill impairment test, which requires computation of the implied fair value of a reporting unit's goodwill. The amount of a goodwill impairment will now be the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for the Company's annual goodwill impairment test and any interim tests during the Company's annual and interim periods beginning on January 1, 2020. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. Prospective application is required. The adoption of the standard is not expected to have a material impact on our financial statements. In February 2017, the FASB issued Accounting Standards Update 2017-05, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (“ASU 2017-05”). ASU 2017-05 clarifies the scope of Subtopic 610-20, which provides guidance for recognizing gains and losses from the sale or transfer of nonfinancial assets in contracts with noncustomers. ASU 2017-05 also provides guidance for partial sales of nonfinancial assets. ASU 2017-05 is effective for the Company’s annual and interim periods beginning on January 1, 2018 and we are required to adopt ASU 2017-05 at the same time that we adopt ASU 2014-09. The guidance permits the use of either a retrospective or cumulative effect transition method. We are evaluating the impact of the standard on our financial statements. In May 2017, the FASB issued Accounting Standards Update 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting (“ASU 2017-09”). ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting under ASC 718. ASU 2017-09 is effective for the Company’s annual and interim periods beginning on January 1, 2018, with early adoption permitted. ASU 2017-09 is to be applied prospectively to an award modified on or after the adoption date. The adoption of the standard is not expected to have a material impact on our financial statements.

Acquisitions

Acquisitions	6 Months Ended
	Jun. 30, 2017
Business Combinations [Abstract]
Acquisitions	Acquisitions For all acquisitions, we allocate the purchase price to assets acquired and liabilities assumed as of the date of acquisition based on the estimated fair values at the date of acquisition. The excess of the fair value of the purchase consideration over the fair values of the identifiable assets and liabilities is recorded as goodwill. Management makes significant estimates and assumptions when determining the fair value of assets acquired and liabilities assumed. These estimates include, but are not limited to, discount rates, projected future net sales, projected future expected cash flows and useful lives. When necessary, we engage third-party valuation firms to assist us in determining fair values of acquired assets and assumed liabilities. Acquisition of Code Plus Components, LLC On March 27, 2017 , the Company acquired substantially all of the assets and assumed certain liabilities of Code Plus Components, LLC (“Code Plus”), a manufacturer of structural components located in Martinsburg, West Virginia, for a preliminary purchase price of $7.1 million . This acquisition allowed the Company to add truss manufacturing capability to its value-added offerings in the Washington, DC metro area. The purchase price includes an initial holdback of $0.4 million due to the sellers one year from the closing date. The holdback amount may be reduced under certain circumstances. Additionally, the acquisition includes an earnout provision which would require the Company to pay the sellers up to an additional $0.8 million upon the acquired operations achieving certain performance targets from the acquisition date through December 31, 2018. The Company funded the transaction through borrowings on the Company’s revolving line of credit. The acquisition was accounted for using the acquisition method of accounting under ASC 805, Business Combinations, whereby the results of operations of Code Plus are included in the Company’s consolidated financial statements beginning on the acquisition date. During the three months ended June 30, 2017, the Company recorded an adjustment which reduced the customer relationship intangible asset and increased goodwill by $1.1 million . After the adjustment, the preliminary purchase price allocation resulted in the initial recognition of goodwill of $3.4 million , a customer relationship intangible asset of $2.3 million and a non-compete agreement intangible asset of $0.5 million , as well as other operating assets and liabilities. The customer relationship intangible asset and non-compete agreement intangible asset have useful lives of 12 years and 5 years , respectively. Goodwill represents the future economic benefits expected to arise from other intangible assets acquired that do not qualify for separate recognition, including assembled workforce and non-contractual relationships, as well as expected future synergies. All of the goodwill recognized is expected to be deductible for tax purposes. For the year ended December 31, 2016, Code Plus generated net sales of approximately $14.2 million . The Company incurred transaction costs of $0 and $0.1 million for the three and six months ended June 30, 2017 , respectively, which are included in selling, general and administrative expenses in the unaudited condensed consolidated statements of operations. Acquisition of Texas Plywood & Lumber Company, Inc. On April 3, 2017 , the Company acquired substantially all of the assets and assumed certain liabilities of Texas Plywood & Lumber Company, Inc. (“TexPly”), a supplier of production millwork and doors in the Dallas-Fort Worth area, for a preliminary purchase price of $32.0 million , of which $2.5 million was deposited in an escrow account to fund post-closing adjustments and other indemnification obligations for a period of one year from the closing date of the acquisition. This acquisition enhances the Company’s value-added offerings and footprint in the Dallas-Fort Worth market. The acquisition was accounted for using the acquisition method of accounting under ASC 805, Business Combinations, whereby the results of operations of TexPly are included in the Company’s consolidated financial statements beginning on the acquisition date. The preliminary purchase price allocation resulted in the initial recognition of goodwill of $3.8 million , a customer relationship intangible asset of $13.4 million , accounts receivable of $5.2 million , inventory of $4.0 million and real property of $5.4 million , as well as other operating assets and liabilities. The customer relationship intangible asset has a useful life of 13 years . Goodwill represents the future economic benefits expected to arise from other intangible assets acquired that do not qualify for separate recognition, including assembled workforce and non-contractual relationships, as well as expected future synergies. All of the goodwill recognized is expected to be deductible for tax purposes. For the year ended December 31, 2016, TexPly generated net sales of approximately $55.2 million . The Company incurred transaction costs of $0 and $0.2 million for the three and six months ended June 30, 2017 , respectively, which are included in selling, general and administrative expenses in the unaudited condensed consolidated statements of operations. The purchase price allocations of Code Plus and TexPly are preliminary and based upon all information available to the Company at the present time, and are subject to change. The Company is in process of finalizing its valuation of the acquired intangible assets, property and equipment and inventory and therefore, the initial purchase accounting is not complete. As we receive additional information during the measurement periods, the fair values assigned to the assets and liabilities may be adjusted. Net sales and estimated pre-tax earnings of Code Plus and TexPly, in aggregate, included in the unaudited condensed consolidated statements of operations for the three months ended June 30, 2017 were $19.2 million and $1.1 million , respectively. Net sales and estimated pre-tax earnings of Code Plus and TexPly, in aggregate, included in the unaudited condensed consolidated statements of operations for the six months ended June 30, 2017 were $19.5 million and $1.1 million , respectively. The impact of the acquisitions was not considered significant for the reporting of pro forma financial information.

Property, Plant and Equipment [Abstract]
Impairment of BMHC ERP System	Impairment of BMHC ERP System During 2013, Building Materials Holding Corporation (“BMHC” or “Legacy BMHC”) selected a new third-party software vendor for its planned Enterprise Resource Planning (“New ERP”) system and began incurring costs related to design, development and implementation of the New ERP. BMHC also began paying an annual licensing fee. During March 2016, the Company decided to integrate all operations under the Enterprise Resource Planning system utilized by Stock Building Supply Holdings, Inc. (“SBS” and the “Legacy SBS ERP system”) and to discontinue use of the New ERP. In connection with this decision, the Company recorded asset impairment charges of approximately $11.9 million in its unaudited condensed consolidated statement of operations for the six months ended June 30, 2016 related to capitalized software development costs for New ERP functionality that the Company had intended to implement in future periods. These costs had previously been recorded as construction-in-progress within property and equipment on the condensed consolidated balance sheets. The Company continues to be obligated under non-cancellable license and service contracts related to the New ERP. During June 2017, the Company determined that it had ceased receiving economic benefit from these contracts. In accordance with ASC 420, Exit or Disposal Cost Obligations, as of the cease use date, the Company recognized approximately $2.8 million of expense within merger and integration costs in its unaudited condensed consolidated statements of operations for the three and six months ended June 30, 2017 , consisting of the recognition of a liability of $2.1 million within accrued expenses and other liabilities on the unaudited condensed consolidated balance sheets for future contractual payments and the acceleration of expense recognition of unamortized prepaid costs of $0.7 million .

As of June 30, 2017 , the estimated market value of the Senior Notes was $16.6 million higher than the carrying amount. The fair value is based on institutional trading activity and was classified as a Level 2 measurement in accordance with ASC 820. Revolving Credit Agreement On December 1, 2015 , we entered into a senior secured credit agreement with Wells Fargo Capital Finance, as administrative agent, and certain other lenders (the “Credit Agreement”), which includes a revolving line of credit (the “Revolver”). The Credit Agreement, as amended, has an aggregate commitment of $375.0 million . We had outstanding borrowings under the Revolver of $66.7 million with net availability of $241.3 million as of June 30, 2017 . The weighted average interest rate on outstanding LIBOR Rate borrowings of $50.0 million was 2.44% and the interest rate on Base Rate borrowings of $16.7 million was 4.50% as of June 30, 2017 . We had $67.0 million in letters of credit outstanding under the Credit Agreement as of June 30, 2017 . The carrying value of the Revolver at June 30, 2017 approximates fair value as the rates are comparable to those at which we could currently borrow under similar terms, are variable and incorporate a measure of our credit risk. As such, the fair value of the Revolver was classified as a Level 2 measurement in accordance with ASC 820. Other Other long-term debt as of June 30, 2017 consists of a $0.4 million term note secured by real property with a maturity of February 2021 . The interest rate is 7.0% and is paid monthly. The estimated market value of other long-term debt approximates the carrying amount.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company evaluates its deferred tax assets quarterly to determine if valuation allowances are required. In assessing the realizability of deferred tax assets, the Company considers both positive and negative evidence in determining whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company had a valuation allowance of $0.1 million against its deferred tax assets related to certain state tax jurisdictions as of June 30, 2017 and December 31, 2016 . To the extent the Company generates future tax net operating losses, the Company may be required to increase the valuation allowance on deferred tax assets, which may unfavorably impact the effective tax rate. The Company has no material uncertain tax positions as of June 30, 2017 and December 31, 2016 . For the three and six months ended June 30, 2017 , the Company’s effective tax rate was 34.8% and 32.7% , respectively, which varied from the federal statutory rate of 35% primarily due to excess tax windfall benefits from stock compensation and a permanent domestic manufacturing deduction under Internal Revenue Code Section 199 (the “Manufacturing Deduction”). For the three and six months ended June 30, 2016 , the effective tax rate was 33.1% and 30.6% , respectively, which varied from the federal statutory rate of 35% primarily due to the excess tax windfall benefit from stock compensation and the Manufacturing Deduction.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies From time to time, various claims, legal proceedings and litigation are asserted or commenced against the Company principally arising from alleged product liability, warranty, casualty, construction defect, contract, tort, employment and other disputes. In determining loss contingencies, management considers the likelihood of loss as well as the ability to reasonably estimate the amount of such loss or liability. An estimated loss is recorded when it is considered probable that such a liability has been incurred and when the amount of loss can be reasonably estimated. It is not certain that the Company will prevail in these matters. However, the Company does not currently believe that the ultimate outcome of any pending matters will have a material adverse effect on its consolidated financial position, results of operations or cash flows.

The weighted average grant date fair value of the performance-based restricted stock units was $21.94 . Currently, the number of performance-based restricted stock units that are issued on the vesting date could range from zero to a maximum of 249,804 , based 50% upon the Company’s average return on invested capital (“ROIC”) over the three year period from January 1, 2017 through December 31, 2019 and 50% upon the Company’s cumulative adjusted earnings per share (“Adjusted EPS”) over the same three year period. During the six months ended June 30, 2016 , in addition to grants of service-based restricted stock unit awards, the Company granted performance-based restricted stock units that vest on March 15, 2019 . The number of performance-based restricted stock units that are issued on the vesting date could range from zero to a maximum of 206,250 , based upon the Company’s cumulative Adjusted EBITDA over the three year period from January 1, 2016 through December 31, 2018 .

Segment Reporting [Abstract]
Segments	Segments ASC 280, Segment Reporting, defines operating segments as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker (“CODM”) in deciding how to allocate resources and in assessing performance. Beginning January 1, 2017, the Company’s operating segments consist of the Mid-Atlantic, Southeast, Texas, Intermountain and Western divisions after the Company realigned certain of its markets, which resulted in the consolidation of the Company’s historical Mountain West division into the Intermountain division. Following the realignment, the CODM continues to review aggregate information to allocate resources and assess performance. Based on this, as well as the similar economic characteristics, nature of products, distribution methods and customers of the divisions both before and after the realignment, the Company has aggregated its operating segments into one reportable segment, “Geographic divisions.” In addition to our reportable segment, the Company’s consolidated results include “Other reconciling items.” Other reconciling items is comprised of our corporate activities and other income and expenses not allocated to the operating segments. The following tables present Net Sales, Adjusted EBITDA and certain other measures for the reportable segment and total Company operations for the three and six months ended June 30, 2017 and 2016 . Adjusted EBITDA is used as a performance metric by the CODM in determining how to allocate resources and assess performance.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic net income per share (“EPS”) is calculated by dividing net income attributable to common stockholders by the weighted average shares outstanding during the period. Diluted EPS is calculated by adjusting weighted average shares outstanding for the dilutive effect of potential common shares, determined using the treasury-stock method. For purposes of the diluted EPS calculation, stock options, restricted stock and restricted stock unit awards are considered to be potential common shares. Performance-based restricted stock units are not included in the calculation of diluted EPS until they are contingently issuable. The basic and diluted EPS calculations for the three and six months ended June 30, 2017 and 2016 are presented below: Three Months Ended June 30, Six Months Ended June 30, (in thousands, except per share amounts) 2017 2016 2017 2016 Income attributable to common stockholders $ 17,596 $ 17,982 $ 21,340 $ 11,226 Weighted average common shares outstanding, basic 66,927 65,839 66,810 65,589 Effect of dilutive securities: Restricted stock 61 229 72 258 Restricted stock units 210 117 194 66 Stock options 196 232 214 224 Weighted average common shares outstanding, diluted 67,394 66,417 67,290 66,137 Basic income per common share $ 0.26 $ 0.27 $ 0.32 $ 0.17 Diluted income per common share $ 0.26 $ 0.27 $ 0.32 $ 0.17 The following table provides the securities that could potentially dilute EPS in the future, but were not included in the computation of diluted EPS for the periods presented because to do so would have been anti-dilutive. The amounts included in this table exclude performance-based restricted stock units. As of June 30, 2017 , the number of currently outstanding performance-based restricted stock units that are issued upon vesting could range from zero to a maximum of 456,054 .

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	Basis of Presentation The unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) that permit reduced disclosure for interim periods. The condensed consolidated balance sheet as of December 31, 2016 was derived from audited financial statements, but does not include all necessary disclosures required by accounting principles generally accepted in the United States of America (“GAAP”). The unaudited condensed consolidated financial statements include all accounts of the Company and its subsidiaries and, in the opinion of management, include all recurring adjustments and normal accruals necessary for a fair statement of the Company’s financial position, results of operations and cash flows for the dates and periods presented. These unaudited financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 (“ 2016 Annual Report on Form 10-K”). Results for interim periods are not necessarily indicative of the results to be expected during the remainder of the current year or for any future period. All material intercompany accounts and transactions have been eliminated in consolidation.
Reclassifications	Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation.

Recently issued accounting pronouncements	Recently adopted accounting pronouncements In July 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2015-11, Simplifying the Measurement of Inventory (“ASU 2015-11”). ASU 2015-11 requires that inventory within the scope of the guidance be measured at the lower of cost and net realizable value. Prior to the issuance of the standard, inventory was measured at the lower of cost or market, where market was defined as replacement cost, with a ceiling of net realizable value and floor of net realizable value less a normal profit margin. Inventory measured using last-in, first-out (LIFO) and the retail inventory method are not impacted by the new guidance. Prospective application is required and early adoption is permitted. ASU 2015-11 became effective for the Company’s annual and interim periods beginning on January 1, 2017. The adoption of the guidance did not have a material impact on our financial statements. Recently issued accounting pronouncements not yet adopted In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), and issued subsequent amendments to the initial guidance within Accounting Standards Update 2016-08, Revenue from Contracts with Customers, Principal versus Agent Considerations (“ASU 2016-08”) issued in March 2016, Accounting Standards Update 2016-10, Revenue from Contracts with Customers, Identifying Performance Obligations and Licensing (“ASU 2016-10”) issued in April 2016, Accounting Standards Update 2016-12, Revenue from Contracts with Customers, Narrow-Scope Improvements and Practical Expedients (“ASU 2016-12”) issued in May 2016 and Accounting Standards Update 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers (“ASU 2016-20”) issued in December 2016 (ASU 2014-09, ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20 collectively “Topic 606”). Topic 606 provides a comprehensive revenue recognition model requiring companies to recognize revenue for the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. In July 2015, the FASB voted to defer the effective date of ASU 2014-09 by one year, and therefore, the standard is effective for the Company’s annual and interim periods beginning on January 1, 2018. The guidance permits the use of either a full retrospective or modified retrospective transition method. We expect to adopt the standard on January 1, 2018 using the modified retrospective transition method, which recognizes the cumulative effect of initially applying the standard in retained earnings on the date of adoption, with the option to utilize certain practical expedients as defined in Topic 606. We are continuing to evaluate the impact of the standard on our financial statements, but based on our preliminary assessment, we believe that contracts with a service element may be impacted as we identify the promised goods and services (performance obligations) within our construction services contracts, which could impact the timing of revenue recognition. Currently, we expect the timing of revenue recognition for our building products contracts to be similar to the current timing. We also continue to evaluate the disclosure requirements of the standard, which are expected to be significant and incremental to the current disclosures. As we continue to evaluate the standard and finalize our assessment, our current conclusions are subject to change. In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases (“ASU 2016-02”). The new standard establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU 2016-02 is effective for the Company’s annual and interim periods beginning on January 1, 2019. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. We are in the process of evaluating the impact of the standard on our financial statements. As a lessee, certain of our various leases under existing guidance are classified as operating leases that are not recorded on the balance sheet but are recorded in the statement of operations as expense is incurred. Upon adoption of the standard, we will be required to record substantially all leases on the balance sheet as a ROU asset and a lease liability. The timing of expense recognition and classification in the statement of operations could change based on the classification of leases as either operating or financing. In August 2016, the FASB issued Accounting Standards Update 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 was issued to decrease the diversity in practice of how certain cash receipts and cash payments are presented and classified in the statement of cash flows by providing guidance on eight specific cash flow issues. ASU 2016-15 is effective for the Company’s annual and interim periods beginning on January 1, 2018, with early adoption permitted and retrospective application required. The adoption of the standard is not expected to have a material impact on our financial statements. In November 2016, the FASB issued Accounting Standards Update 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU 2016-18”). ASU 2016-18 requires that the statement of cash flows include restricted cash in the beginning and end-of-period total amounts shown and that the statement of cash flows explain the changes in restricted cash during the period. ASU 2016-18 is effective for the Company's annual and interim periods beginning on January 1, 2018. Retrospective application is required and early adoption is permitted. The adoption of the standard is not expected to have a material impact on our financial statements. In January 2017, the FASB issued Accounting Standards Update 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”). ASU 2017-01 provides guidance in determining when a set of assets and activities meets the definition of a business. ASU 2017-01 is effective for the Company's annual and interim periods beginning on January 1, 2018. Early application is permitted for transactions meeting certain criteria and prospective application is required. The adoption of the standard is not expected to have a material impact on our financial statements. In January 2017, the FASB issued Accounting Standards Update 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). ASU 2017-04 simplifies the accounting for goodwill impairment by removing Step 2 of the goodwill impairment test, which requires computation of the implied fair value of a reporting unit's goodwill. The amount of a goodwill impairment will now be the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for the Company's annual goodwill impairment test and any interim tests during the Company's annual and interim periods beginning on January 1, 2020. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. Prospective application is required. The adoption of the standard is not expected to have a material impact on our financial statements. In February 2017, the FASB issued Accounting Standards Update 2017-05, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (“ASU 2017-05”). ASU 2017-05 clarifies the scope of Subtopic 610-20, which provides guidance for recognizing gains and losses from the sale or transfer of nonfinancial assets in contracts with noncustomers. ASU 2017-05 also provides guidance for partial sales of nonfinancial assets. ASU 2017-05 is effective for the Company’s annual and interim periods beginning on January 1, 2018 and we are required to adopt ASU 2017-05 at the same time that we adopt ASU 2014-09. The guidance permits the use of either a retrospective or cumulative effect transition method. We are evaluating the impact of the standard on our financial statements. In May 2017, the FASB issued Accounting Standards Update 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting (“ASU 2017-09”). ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting under ASC 718. ASU 2017-09 is effective for the Company’s annual and interim periods beginning on January 1, 2018, with early adoption permitted. ASU 2017-09 is to be applied prospectively to an award modified on or after the adoption date. The adoption of the standard is not expected to have a material impact on our financial statements.

Acquisitions	Acquisitions For all acquisitions, we allocate the purchase price to assets acquired and liabilities assumed as of the date of acquisition based on the estimated fair values at the date of acquisition. The excess of the fair value of the purchase consideration over the fair values of the identifiable assets and liabilities is recorded as goodwill. Management makes significant estimates and assumptions when determining the fair value of assets acquired and liabilities assumed. These estimates include, but are not limited to, discount rates, projected future net sales, projected future expected cash flows and useful lives. When necessary, we engage third-party valuation firms to assist us in determining fair values of acquired assets and assumed liabilities.
