Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	1. Basis of Presentation Builders FirstSource, Inc., a Delaware corporation formed in 1998, is a leading supplier of building materials, manufactured components and construction services to professional contractors, sub-contractors, and consumers. Following our acquisition of ProBuild Holdings, LLC (“ProBuild”) in July 2015, the company operates locations in 40 states across the United States. In this quarterly report, references to the “Company,” “we,” “our,” “ours” or “us” refer to Builders FirstSource, Inc. and its consolidated subsidiaries (including ProBuild as of July 31, 2015), unless otherwise stated or the context otherwise requires. In the opinion of management, the accompanying unaudited condensed consolidated financial statements 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. 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 significant intercompany accounts and transactions have been eliminated in consolidation. The condensed consolidated balance sheet as of December 31, 2014 is derived from the audited consolidated financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. This condensed consolidated balance sheet as of December 31, 2014 and the unaudited condensed consolidated financial statements included herein should be read in conjunction with the more detailed audited consolidated financial statements for the year ended December 31, 2014 included in our most recent annual report on Form 10-K. Accounting policies used in the preparation of these unaudited condensed consolidated financial statements are consistent, except as noted below, with the accounting policies described in the Notes to Consolidated Financial Statements included in our Form 10-K. Certain prior period amounts have been reclassified to conform to the current year presentation due to the ProBuild acquisition and the adoption of updated accounting guidance. The accompanying condensed consolidated balance sheet as of December 31, 2014 has been revised to present deferred loan costs associated with term debt as a reduction to long-term debt instead of a component of other assets. In the accompanying condensed consolidated balance sheet as of December 31, 2014, $9.0 million has been reclassified from other assets to long-term debt. Deferred loan costs associated with revolving debt arrangements continue to be presented as a component of other assets. Previously the Company presented all deferred loan costs as a component of other assets. This change in accounting principle was made in accordance with the updated guidance issued by the Financial Standards Accounting Board (“FASB”) described in Note 12. This update had no impact on guidance relating to the recognition and measurement of deferred loan costs.

Business Combinations [Abstract]
Acquisitions	2. Acquisitions On February 9, 2015, the Company acquired certain assets and the operations of Timber Tech Texas, Inc. and its affiliates (“Timber Tech”) for $5.8 million in cash (including certain adjustments). Timber Tech is based in Cibolo, Texas, which is approximately 25 miles northeast of downtown San Antonio. Timber Tech is a manufacturer of roof trusses, floor trusses, wall panels and sub-components, as well as a supplier of glue laminated timber and veneer lumber beams. On July 31, 2015, we acquired all of the operating affiliates of ProBuild through the purchase of all issued and outstanding equity interests of ProBuild for $1.63 billion in cash, subject to certain adjustments. The purchase price was funded by the net proceeds received from the financing transactions described in Note 4. Headquartered in Denver, Colorado, ProBuild is one of the nation’s largest professional building materials suppliers. As a result of the ProBuild acquisition, the Company has a greater diversification of products and services and a significantly improved geographic footprint. The Timber Tech and ProBuild acquisitions were accounted for by the acquisition method, and accordingly the results of operations were included in the Company’s consolidated financial statements from the acquisition date. The purchase price was allocated to the assets acquired based on estimated fair values at the acquisition date, with the excess of purchase price over the estimated fair value of the net assets acquired recorded as goodwill. The accounting for these acquisitions is preliminary and subject to adjustment as it has not been completed at the date of this filing given the proximity to the acquisition dates . We incurred $8.8 million and $20.4 million in costs related to the acquisitions during the three and nine months ended September 30, 2015, respectively. These costs include due diligence costs and transaction costs to complete the acquisition, and have been recognized in selling, general and administrative expense in the accompanying condensed consolidated statements of operations and comprehensive income (loss) for the three months and nine months ended September 30, 2015. The following table summarizes the aggregate fair values of the assets acquired and liabilities assumed at the acquisition date for ProBuild, net of cash (in thousands): Accounts receivable $ 490,562 Other receivables 34,718 Inventory 394,633 Other current assets 12,101 Property, plant and equipment 655,037 Assets held for sale 10,912 Goodwill (Note 9) 459,472 Intangible assets (Note 10) 321,209 Other assets 2,028 Total assets acquired 2,380,672 Checks outstanding (32,378 ) Current maturities of long term debt and lease obligations (25,456 ) Accounts payable (339,673 ) Accrued expenses (215,395 ) Other long-term liabilities (46,059 ) Long-term debt and lease obligations, net of current maturities (262,391 ) Total liabilities assumed (921,352 ) Total net assets acquired $ 1,459,320 All of the goodwill and intangible assets recognized from the Timber Tech and ProBuild acquisitions are expected to be deductible for tax purposes, with the goodwill recognized from these acquisitions being amortized ratably over a 15 year period. The ProBuild acquisition will be treated as an asset purchase for tax purposes. The operating results of the acquisitions have been included in the consolidated statements of operations and comprehensive income (loss) from their acquisition dates through September 30, 2015. Net sales and net income attributable to ProBuild were $811.9 million and $24.8 million, respectively, for the period of August 1, 2015 through September 30, 2015. Net sales and net income attributable to Timber Tech are not material. The following table reflects the unaudited pro forma operating results for the Company for the three and nine months ended September 30, 2015 and 2014, which gives effect to the acquisition of ProBuild as if it had occurred on January 1, 2014. The pro forma results are based on assumptions that the Company believes are reasonable under the circumstances. The pro forma results are not necessarily indicative of future results. The pro forma financial information includes the historical results of the Company and ProBuild adjusted for certain items, which are described below, and does not include the effects of any synergies or cost reduction initiatives related to the acquisition of ProBuild. Pro forma information for Timber Tech is not presented as it is not material. Three Months Ended September 30, Nine Months Ended September 30, 2015 2014 2015 2014 (unaudited pro forma) (in thousands, except per share amounts) Net sales $ 1,698,971 $ 1,711,263 $ 4,610,937 $ 4,601,555 Net income (loss) $ 19,233 $ 14,244 $ (21,362 ) $ (105,878 ) Basic net income (loss) per share $ 0.18 $ 0.13 $ (0.20 ) $ (0.99 ) Diluted net income (loss) per share $ 0.17 $ 0.12 $ (0.20 ) $ (1.00 ) Pro forma net income (loss) for the three and nine months ended September 30, 2015 and 2014 reflects adjustments primarily related to depreciation and amortization, the conversion from last-in, first-out to first-in, first out inventory valuation, and interest expense. Pro forma net income (loss) was adjusted to exclude transaction-related expenses of $33.3 million ($22.8 million incurred by the Company and $10.5 million incurred by ProBuild) and $46.7 million ($34.4 million incurred by the Company and $12.3 million incurred by ProBuild) in the three and nine months ended September 30, 2015, respectively. Pro forma net income (loss) for the nine months ended September 30, 2014 was adjusted to include these transaction-related expenses.

Earnings Per Share [Abstract]
Net Income (Loss) per Common Share	3. Net Income (Loss) per Common Share Net income (loss) per common share (“EPS”) is calculated in accordance with the Earnings per Share Our restricted stock shares include rights to receive dividends that are not subject to the risk of forfeiture even if the underlying restricted stock shares on which the dividends were paid do not vest. In accordance with the Earnings per Share For the purpose of computing diluted EPS, options to purchase 5.5 million shares of common stock and 1.5 million restricted stock units (“RSUs’) were not included in the computations of diluted EPS for the three and nine months ended September 30, 2015 because their effect was anti-dilutive. Incremental shares attributable to average warrants outstanding during the nine months ended September 30, 2015 were not included in the computation of diluted EPS for the nine months ended September 30, 2015 as their effect was anti-dilutive. There were no outstanding warrants as of September 30, 2015 as all of the remaining stock warrants were exercised in April 2015. Weighted average shares outstanding have been adjusted for common shares underlying 6.3 million options, 1.9 million RSUs, and 0.7 million warrants for the three and nine months ended September 30, 2014. In addition, $1.3 million of income due to fair value adjustments related to the warrants was excluded from net income in the computation of diluted EPS for the three and nine months ended September 30, 2014. The table below presents a reconciliation of weighted average common shares used in the calculation of basic and diluted EPS (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2015 2014 2015 2014 Weighted average shares for basic EPS 105,856 98,104 101,096 98,010 Dilutive effect of options, warrants, and RSUs — 2,256 — 2,618 Weighted average shares for diluted EPS 105,856 100,360 101,096 100,628

The purchase price was funded with the net cash proceeds from (i) the sale of $700.0 million in aggregate principal amount of 10.75% senior unsecured notes due 2023 (the “2023 notes”), (ii) entry into a $600.0 million term loan credit agreement (the “2015 term loan”) provided by a syndicate of financial institutions led by Deutsche Bank AG, New York Branch, as administrative and collateral agent, (iii) a $295.0 million draw on an amended and restated $800.0 million senior secured revolving credit facility (the“2015 facility”) provided by a syndicate of financial institutions led by SunTrust Bank as administrative and collateral agent, and (iv) a public offering of 9.2 million new shares of our common stock at an offering price of $12.80 per share (the “equity offering”). In connection with the financing transactions described above, we incurred approximately $64.9 million of various third-party fees and expenses. Of these costs, $18.1 million were allocated to the 2023 notes, $16.0 million were allocated to the 2015 term loan, $11.2 million were allocated to the 2015 facility and $6.4 million were allocated to the equity offering. The costs allocated to the 2023 notes and the 2015 term loan have been recorded as reductions to long-term debt and will be amortized over their respective terms using the effective interest method. The costs allocated to the 2015 facility have been recorded as other assets and will be amortized over its term on a straight-line basis. The costs allocated to the equity offering have been recorded as a reduction to additional paid-in capital. In addition, $13.2 million in costs relate to commitment fees paid for bridge and backstop financing facilities entered into in connection with these financing transactions, neither of which was utilized. As such, these fees were recorded as interest expense in the third quarter of 2015. At the closing of these transactions, there were approximately $3.0 million in unamortized debt issuance costs associated with the 2013 $175.0 million senior secured revolving credit facility (the “2013 facility”), provided by a syndicate of financial institutions led by SunTrust Bank as administrative agent . Of these costs, approximately $0.9 million were recorded as interest expense in the third quarter of 2015. The remaining $2.1 million in unamortized costs associated with the 2013 facility are being amortized over the term of the 2015 facility. Senior Unsecured Notes due 2023 As of September 30, 2015, we have $700.0 million outstanding in aggregate principal amount of the 2023 notes that mature on August 15, 2023. The 2023 notes were sold in a private offering at an issue price equal to 100% of their face value. Interest accrues on the 2023 notes at a rate of 10.75% per annum and is payable semi-annually on March 1 and September 1 of each year, commencing on March 1, 2016. The terms of the notes are governed by an indenture, dated as of July 31, 2015, among the Company, the guarantors named therein and Wilmington Trust, National Association, as trustee (the “trustee”). The notes are subject to an indenture and a supplemental indenture, each dated as of July 31, 2015, among the Company, the guarantors named therein and Wilmington Trust, National Association, as trustee (the “trustee”). Pursuant to the indenture and supplemental indenture, the company’s significant operating subsidiaries, including ProBuild and certain of its subsidiaries, agreed to serve as guarantors of the 2023 notes. The 2023 notes are the Company’s senior unsecured obligations and will rank equally with all of its existing and future senior unsecured debt and will be senior to all of its existing and future subordinated debt. The indenture contains certain restrictive covenants, which among other things, limit the ability of the Company to incur additional debt, issue preferred stock, create liens, pay dividends, make certain investments, sell certain assets, enter into certain types of transactions with affiliates, and effect mergers and consolidations. At any time prior to August 15, 2018, the Company may redeem the 2023 notes in whole or in part at a redemption price equal to 100% of the principal amount of the 2023 notes plus a premium as specified in the indenture. At any time on or after August 15, 2018, the Company may redeem the 2023 notes at the redemption prices set forth in the indenture plus accrued and unpaid interest. In addition, the Company may redeem up to 40% of the aggregate principal amount of the 2023 notes with the net cash proceeds of one or more equity offerings, as described in the indenture, at a price equal to 110.75% of the principal amount thereof, plus accrued and unpaid interest. In the event of a change in control, we may be required to repurchase all or part of the 2023 notes at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest. 2015 Term Loan Credit Agreement As of September 30, 2015, we have $600.0 million outstanding under the 2015 term loan, which matures on July 31, 2022. The 2015 term loan, which was issued at 99%, bears interest, at our option, at either a eurodollar rate or a base rate, plus, in each case an applicable margin. The margin will be 5.0% per annum in the case of eurodollar rate loans and 4.0% per annum in the case of base rate loans. The 2015 term loan has mandatory principal repayments of $1.375 million which are payable in March, June, September, and December of each year, commencing in December 2015, provided that each such payment is subject to reduction as a result of certain prepayments of the loans in accordance with the loan documentation. The weighted average interest rate of the term loan was 6.0% during the third quarter of 2015. 2015 Senior Secured Revolving Credit Facility The 2015 facility provides for an $800.0 million revolving credit line to be used for working capital and general corporate purposes. The available borrowing capacity, or borrowing base, is derived from a percentage of the Company’s eligible receivables and inventory, as defined by the agreement, subject to certain reserves. As of September 30, 2015, the net borrowing availability under the 2015 facility is $584.5 million after being reduced by outstanding letters of credit of $80.5 million and $135.0 million of borrowings currently outstanding. During the third quarter of 2015, we borrowed $295.0 million and repaid $160.0 million at a weighted average interest rate of 1.7%. The 2015 facility matures on July 31, 2020. Borrowings under the 2015 facility bear interest, at our option, at either a eurodollar rate or a base rate, plus, in each case an applicable margin. The applicable margin ranges from 1.25% to 1.75% per annum in the case of eurodollar rate loans and 0.25% to 0.75% per annum in the case of base rate loans. The margin in either case is based on a measure of availability under the 2015 facility. A variable commitment fee, currently 0.375% per annum, is charged on the unused amount of the revolver based on quarterly average loan utilization. Letters of credit under the 2015 facility are assessed at a rate equal to the applicable eurodollar margin, currently 1.5%, as well as a fronting fee at a rate of 0.125% per annum. These fees are payable quarterly in arrears at the end of March, June, September, and December. All obligations under the 2015 term loan and 2015 facility will be guaranteed jointly and severally by the Company and all other subsidiaries that guarantee the 2021 notes. All obligations and the guarantees of those obligations will be secured by substantially all of the assets of the Company and the guarantors subject to certain exceptions and permitted liens, including (i) with respect to the 2015 term loan, a first-priority security interest in such assets that constitute Notes Collateral (as defined below) and a second priority security interest in such assets that constitute ABL Collateral (as defined below), and (ii) with respect to the 2015 facility, a first-priority security interest in such assets that constitute ABL Collateral and a second-priority security interest in such assets that constitute Notes Collateral. “ABL Collateral” includes substantially all presently owned and after-acquired accounts receivable, inventory, rights of unpaid vendors with respect to inventory, deposit accounts, commodity accounts, securities accounts and lock boxes, investment property, cash and cash equivalents, and general intangibles, books and records, supporting obligations and documents and related letters of credit, commercial tort claims or other claims related to and proceeds of each of the foregoing. “Notes Collateral” includes all collateral which is not ABL collateral. The 2015 term loan and the 2015 facility contain restrictive covenants which, among other things, limit the Company’s ability to incur additional indebtedness, incur liens, engage in mergers or other fundamental changes, sell certain assets, pay dividends, make acquisitions or investments, prepay certain indebtedness, change the nature of our business, and engage in certain transactions with affiliates, respectively. In addition, the 2015 facility also contains a financial covenant requiring the satisfaction of a minimum fixed charge ratio of 1.00 to 1.00 in the event that the Company does not meet a minimum measure of availability, currently the larger of $80.0 million or 10% of the maximum borrowing amount under the 2015 facility. As of September 30, 2015, we were not in violation of any covenants or restrictions imposed by any of our debt agreements. Fair Value The only financial instrument which was measured at fair value on a recurring basis was our warrants. However, on April 14, 2015, the remaining 0.7 million of outstanding, detachable warrants were exercised. The warrants were considered to be derivative financial instruments and were classified as liabilities. We recognized a non-cash, fair value adjustment of approximately $4.7 million in the second quarter of 2015. This fair value adjustment was recorded as interest expense in the accompanying condensed consolidated statement of operations and comprehensive income (loss). The table below presents the effect of our derivative financial instrument on the condensed consolidated statements of operations and comprehensive income (loss) (in thousands): Derivative as Amount of Gain (Loss) Recognized Location of Gain (Loss) Three Months Ended September 30, Nine Months Ended September 30, Recognized in Income 2015 2014 2015 2014 Warrants Interest expense, net $ — $ 1,340 $ (4,563 ) $ 1,321 We used the income approach to value our warrants by using the Black-Scholes option-pricing model. Using this model, the risk-free interest rate was based on the U.S. Treasury yield curve in effect on the valuation date. The expected life was based on the period of time until the expiration of the warrants. Expected volatility was based on the historical volatility of our common stock over the most recent period equal to the expected life of the warrants. The expected dividend yield was based on our history of not paying regular dividends in the past. These techniques incorporated Level 1 and Level 2 inputs. Significant inputs to the derivative valuation for the warrants were observable in the active markets and are classified as Level 2 in the hierarchy. The following fair value hierarchy table presents information about our financial instrument measured at fair value on a recurring basis using significant other observable inputs (Level 2) (in thousands): Carrying Value As of September 30, 2015 Fair Value Measurement as of Carrying Value December 31, 2014 Fair Value Measurement as of Warrants (included in Other long-term liabilities) $ — $ — $ 3,375 $ 3,375 We have elected to report the value of our 2021 notes, 2023 notes, and the 2015 term loan at amortized cost. The fair values of the 2021 notes and the 2023 notes at September 30, 2015 were approximately $367.8 million and $708.7 million, respectively, and were determined using Level 2 inputs based on market prices. The carrying value of the 2015 term loan at September 30, 2015 approximates fair value as the 2015 term loan agreement contains a variable interest rate. As such, the fair value measurement of the term loan was also classified as level 2 in the hierarchy. Lease Finance Obligations As a result of the ProBuild acquisition, the Company is party to 172 individual property lease agreements with a single lessor as of September 30, 2015. These lease agreements have initial terms ranging from nine to fifteen years (expiring from 2016 through 2021) and renewal options in five-year increments providing for up to approximately 30-year remaining total lease terms. A related agreement between the lessor and the Company gives the Company the right to acquire a limited number of the leased facilities at fair market value. As a result of these purchase rights, the Company treats all of the properties that it leases from this lessor as a financing arrangement. The Company is also party to certain additional agreements with the same lessor which commit the Company to perform certain repair and maintenance obligations under the leases in a specified manner and timeframe. Since July 31, 2015, the Company has exercised purchase right options on 2 properties that were subject to leases with the lessor resulting in a non-cash retirement of assets and related lease obligations of $1.5 million for the three and nine months ended September 30, 2015. In 2006, we completed construction on a new multi-purpose facility. Based on the evaluation of the construction project in accordance with the Leases topic of the Codification, we were deemed the owner of the facility during the construction period. Effectively, a sale and leaseback of the facility occurred when construction was completed and the lease term began. This transaction did not qualify for sale-leaseback accounting. As a result the Company treats the lease of this facility as a financing arrangement. As of September 30, 2015, lease finance obligations consist of $281.4 million, with cash payments of $4.1 million for the nine months ended September 30, 2015. These lease finance obligations are included on the condensed consolidated balance sheet as a component of long-term debt and lease obligations. The related assets are recorded as components of property, plant, and equipment on the condensed consolidated balance sheet. Future maturities of long-term debt and lease finance obligations as of September 30, 2015 were as follows (in thousands): 2015 (from October 1, 2015) $ 1,770 2016 23,126 2017 17,492 2018 7,322 2019 7,464 Thereafter 2,009,192 Total long-term debt and lease finance obligations (including current maturities) $ 2,066,366

Disclosure Of Compensation Related Costs Share Based Payments And Retirement Plans [Abstract]
Employee Stock-Based Compensation and Retirement Plans	6. Employee Stock-Based Compensation and Retirement Plans Stock Option Grant On February 11, 2015, our board of directors granted 142,000 stock options to employees under our 2014 Incentive Plan. All the awards vest at 25% per year at each anniversary of the grant date over four years. The exercise price for the options was $6.35 per share, which was the closing stock price on the grant date. The weighted average grant date fair value of the options was $4.20 and was determined using the Black-Scholes option-pricing model with the following weighted average assumptions: Expected life 6.0 years Expected volatility 75.2% Expected dividend yield 0.00% Risk-free rate 1.75% The expected life represents the period of time the options are expected to be outstanding. We used the simplified method for determining the expected life assumption due to limited historical exercise experience on our stock options. The expected volatility is based on the historical volatility of our common stock over the most recent period equal to the expected life of the option. The expected dividend yield is based on our history of not paying regular dividends in the past and our current intention to not pay regular dividends in the foreseeable future. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant and has a term equal to the expected life of the options. Restricted Stock Units Grant On February 11, 2015, our board of directors granted 142,000 RSUs to employees under our 2014 Incentive Plan. All of the awards vest at 25% per year at each anniversary of the grant date over the next four years. The grant date fair value for the restricted stock units was $6.35 per share, which was the closing stock price on the grant date. Retirement Plans Through the ProBuild acquisition, the Company acquired a defined benefit plan, the ProBuild Retirement Plan, which was terminated as of January 30, 2015 and is currently being actively liquidated. Accrued pension costs, which represent the unfunded status of the ProBuild Retirement Plan, were $5.5 million at September 30, 2015. The Company expects to fully fund all plan benefits and make distributions of all remaining plan benefits upon completion of termination, which is expected to occur in the fourth quarter of 2015. In addition, as a result of the ProBuild acquisition the Company now maintains two active defined contribution 401(k) plans.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	7. Income Taxes We evaluate our deferred tax assets on a quarterly basis to determine whether a valuation allowance is required. In accordance with the Income Taxes Poor housing market conditions have contributed to our cumulative loss position for the past several years. We believe this, as well as uncertainty around the extent and timing of the continued housing market recovery, represents significant negative evidence in considering whether our deferred tax assets are realizable. Further, we do not believe that relying on projections of future taxable income to support the recovery of deferred tax assets is sufficient. Based on an evaluation of positive and negative evidence, we concluded that the negative evidence regarding our ability to realize our deferred tax assets outweighed the positive evidence as of September 30, 2015. During the three and nine months ended September 30, 2015 we recorded net increases to the valuation allowance of $1.1 million and $2.9 million against the net deferred tax assets as we generated net operating losses during those periods related to our continuing operations. During the three and nine months ended September 30, 2014, we recorded net reductions to the valuation allowance of $3.3 million and $6.3 million against our net deferred tax assets as we generated net income during these periods. Our effective tax rate was (12.8%) and (8.7%) for the three and nine months ended September 30, 2015, respectively. For the three and nine months ended September 30, 2014 our effective tax rate was 4.9% and 3.6%, respectively. Without continued improvement in housing activity, we could be required to establish additional valuation allowances. However, we had positive earnings before taxes in 2014. To the extent we continue to generate sufficient taxable income in the same jurisdictions in the future to utilize the tax benefits of the related net deferred tax assets, we may reverse some or all of the valuation allowance. We currently estimate that we will likely transition into a three year cumulative income position, including an evaluation of ProBuild’s historical results, on a rolling three year period at some time during the year ending December 31, 2016. However, there continues to be uncertainty around housing market projections. Simply coming out of a cumulative loss is not viewed as a bright line and may not be considered sufficient positive evidence to reverse some or all of the valuation allowance if there are other offsetting negative factors. In upcoming quarters, we will closely monitor the positive and negative evidence surrounding our ability to realize our deferred tax assets. Utilization of deferred tax assets could be limited by Section 382 of the Internal Revenue Code, which imposes annual limitations on the utilization of net operating loss (“NOL”) carryforwards, other tax carryforwards, and certain built-in losses upon an ownership change as defined under that section. In general terms, an ownership change may result from transactions that increase the aggregate ownership of certain stockholders in the Company’s stock by more than 50 percentage points over a three year testing period (“Section 382 Ownership Change”). If the Company were to experience a Section 382 Ownership Change, an annual limitation would be imposed on certain of the Company’s tax attributes, including NOL and capital loss carryforwards, and certain other losses, credits, deductions or tax basis. We base our estimate of deferred tax assets and liabilities on current tax laws and rates. In certain cases, we also base our estimate on business plan forecasts and other expectations about future outcomes. Changes in existing tax laws or rates could affect our actual tax results, and future business results may affect the amount of our deferred tax liabilities or the valuation of our deferred tax assets over time. Due to uncertainties in the estimation process, particularly with respect to changes in facts and circumstances in future reporting periods, as well as the residential homebuilding industry’s cyclicality and sensitivity to changes in economic conditions, it is possible that actual results could differ from the estimates used in previous analyses. Accounting for deferred taxes is based upon estimates of future results. Differences between the anticipated and actual outcomes of these future results could have a material impact on our consolidated results of operations or financial position.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	8. Commitments and Contingencies We lease certain land, buildings and equipment used in operations. These leases are generally accounted for as operating leases with initial terms ranging from one to 20 years and they generally contain renewal options. Certain operating leases are subject to contingent rentals based on various measures, primarily consumer price index increases. In addition, we have residual value guarantees on certain equipment leases. Total rent expense under operating leases was approximately $12.7 million and $26.1 million for the three and nine months ended September 30, 2015, respectively, and $6.9 million and $18.7 million for the three and nine months ended September 30, 2014, respectively. Future minimum commitments for noncancelable operating leases with initial or remaining lease terms in excess of one year are as follows: Related Party Total* (In thousands) Years ending December 31, 2015 (from October 1, 2015) $ 578 $ 14,658 2016 2,024 55,962 2017 1,999 49,096 2018 1,617 38,984 2019 1,543 26,818 Thereafter 2,426 52,042 $ 10,187 $ 237,560 * Includes related party future minimum commitments for noncancelable operating leases. As of September 30, 2015, we had outstanding letters of credit totaling $80.5 million under our 2015 facility that principally support our self-insurance programs. We are a party to various legal proceedings in the ordinary course of business. Although the ultimate disposition of these proceedings cannot be predicted with certainty, management believes the outcome of any claim that is pending or threatened, either individually or on a combined basis, will not have a material adverse effect on our consolidated financial position, cash flows or results of operations. However, there can be no assurances that future costs related to legal proceedings would not be material to our results of operations or liquidity for a particular period.

Goodwill	9. Goodwill The following table sets forth the change in the carrying amount of goodwill for the Company in 2015 (in thousands): 2015 Balance as of January 1, Goodwill $ 184,410 Accumulated impairment losses (44,636 ) 139,774 Acquisitions and other purchase price adjustments 456,633 Balance as of September 30, Goodwill $ 641,043 Accumulated impairment losses (44,636 ) $ 596,407 In 2015, the change in the carrying amount of goodwill is attributable to our acquisitions of ProBuild and Timber Tech and to purchase price adjustments related to previous acquisitions. The amount allocated to goodwill is attributable to the assembled workforce of the acquired companies as well as the synergies expected to arise as a result of these acquisitions. The accounting for the acquisition of ProBuild is preliminary and therefore the assignment of goodwill to reporting units following the ProBuild acquisition has not been completed due to the proximity of the closing date of the ProBuild acquisition to the date of the financial statements.

We also recorded $19.5 million of unfavorable lease obligations. The weighted average useful lives of the acquired assets are 11.0 years for trade names, 17.8 years for customer relationships, and 10.0 years for both the favorable and unfavorable lease intangibles. The accounting for the ProBuild acquisition is preliminary, as such the amounts recorded as intangible assets are also preliminary. During the three and nine months ended September 30, 2015, we recorded net amortization expense in relation to the above-listed intangible assets of $4.6 million and $5.7 million, respectively. In addition, as a result of the facility closure activities following the ProBuild acquisition, we recorded a $1.4 million impairment charge against our intangible assets for both the three and nine months ended September 30, 2015. During the three and nine months ended September 30, 2014, we recorded amortization expense of $0.3 million and $0.5 million, respectively.

Segment and Product Information	11. Segment and Product Information We offer an integrated solution to our customers providing manufacturing, supply, and installation of a full range of structural and related building products. We provide a wide variety of building products and services directly to homebuilder customers. We manufacture floor trusses, roof trusses, wall panels, stairs, millwork, windows, and doors. We also provide a full range of construction services. These product and service offerings are distributed across approximately 450 locations operating in 40 states across the United States, which have been reorganized into nine geographical regions following the ProBuild acquisition. Centralized financial and operational oversight, including resource allocation and assessment of performance on an income (loss) from continuing operations before income taxes basis, is performed by our CEO, whom we have determined to be our chief operating decision maker (“CODM”). As a result of the reorganization following the ProBuild acquisition, the Company has nine operating segments aligned with its nine geographical regions (Regions 1 through 9). While all of our operating segments have similar nature of products, distribution methods and customers, certain of our operating segments have been aggregated due to also containing similar economic characteristics, resulting in the following composition of reportable segments: · Regions 1 and 2 have been aggregated to form the “Northeast” reportable segment · Regions 3 and 5 have been aggregated to form the “Southeast” reportable segment · Regions 4 and 6 have been aggregated to form the “South” reportable segment · Region 7, 8 and 9 have been aggregated to form the “West” reportable segment In addition to our reportable segments, our consolidated results include corporate overhead, other various operating activities that are not internally allocated to a geographical region nor separately reported to the CODM, and certain reconciling items primarily related to allocations of corporate overhead and rent expense, which have collectively been presented as “All Other”. The accounting policies of the segments are consistent with those described in Note 1, except for noted reconciling items.
