	Stock Building Supply Holdings, Inc., formerly known as Saturn Acquisition Holdings, LLC ("Saturn"), and its subsidiaries (the “Company,” “we,” “us,” “our,” and “management”) distributes lumber and building materials to new construction and repair and remodel contractors. Additionally, we provide solution-based services to our customers, including component design, production specification and installation management services.
	On May 2, 2013, Saturn filed a Certificate of Conversion with the Secretary of State of the State of Delaware to effect a conversion from a Delaware limited liability company to a Delaware corporation and change the name of Saturn to Stock Building Supply Holdings, Inc. In connection with the conversion to a corporation, each one share of Class A common stock, Class B common stock, Redeemable Class A Junior Preferred stock and Convertible Class C Preferred stock converted into one share of the same class of the converted entity. Each share of Redeemable Class B Senior Preferred stock converted into 1.02966258 shares of the same class of the converted entity (with the additional shares representing the accumulated dividends thereon to the date of the conversion).
	On July 29, 2013, the Company filed an amendment to its Certificate of Incorporation effecting a 25.972-for-1 stock split of the Company’s common stock. The consolidated financial statements give retroactive effect to the stock split.
	Due to the seasonal nature of our industry, sales are usually lower in the first and fourth quarters than in the second and third quarters.

	Initial Public Offering
	On August 14, 2013, the Company completed its Initial Public Offering ("IPO") of 7,000,000 shares of common stock at a price of $14.00 per share. A total of 4,411,765 shares were offered by the Company and a total of 2,588,235 shares were sold by Gores Building Holdings, LLC and other selling stockholders of the Company. In connection with the IPO, the underwriters exercised in full their option to purchase an additional 1,050,000 shares of common stock from certain selling stockholders. As a result, the total IPO size was 8,050,000 shares. The Company received net proceeds of $55,821 after deducting underwriting discounts of $4,324 and other expenses directly associated with the IPO of $1,620, including legal, accounting, printing and roadshow expenses. The Company incurred an additional $596 of expenses directly associated with the IPO that were not paid as of September 30, 2013, of which $347 and $249 are included in accounts payable and accrued expenses and other liabilities, respectively, on the condensed consolidated balance sheets. The underwriting discounts and other expenses directly associated with the IPO have been recorded in additional paid-in-capital as a reduction of the IPO proceeds on the condensed consolidated balance sheets as of September 30, 2013. The Company used $46,821 of the net proceeds to pay down outstanding balances under the Revolver and $9,000 was paid to The Gores Group, LLC ("Gores") to terminate our management services agreement with Gores.
	Upon the closing of the IPO, all outstanding shares of the Company’s Class A common stock and Class B common stock were reclassified and converted into an equal number of shares of a single class of common stock, all outstanding options to purchase Class B common stock held by certain members of management were reclassified and converted into options to purchase an equal number of shares of common stock and all outstanding Redeemable Class A Junior Preferred stock, Redeemable Class B Senior Preferred stock and Convertible Class C Preferred stock were reclassified and converted into an aggregate of 7,191,891 shares of the Company’s common stock. See Note 14 for a discussion of equity awards issued in connection with the IPO.
	As a result of the IPO, the Company expensed certain costs associated with the offering that were not directly attributable to the securities offered. The following table summarizes these costs for the three and nine months ended September 30, 2013:
		Three months Ended September 30, 2013		Nine Months Ended September 30, 2013

	Restatement of previously issued consolidated financial statements
	In connection with the IPO, the Company restated its previously issued consolidated financial statements and related footnotes as of December 31, 2012 as set forth in these consolidated financial statements. The Company updated the methodology utilized in the January 1, 2012 valuation of its Class A and Class B common stock, as well as placed additional weighting on value indicated by the purchase by the Company of Wolseley plc's stockholder interests in November 2011. The updated valuation of the Company’s Class A and Class B common stock resulted in the following: (i) correction of compensation expense related to a modification of the exercise price of the Company’s outstanding stock options, the issuance of new stock options and the purchase by management of shares of Class B common stock in 2012 and (ii) recognition of a beneficial conversion feature for the Convertible Class C Preferred stock.
	The Company recorded additional compensation expense related to the modification of the exercise price of outstanding stock options, the issuance of new options and the purchase of shares of Class B Common stock by management. The Company determined that the increase in the estimated fair value of the Class B Common stock increased the Company’s total compensation expense recognized as a result of these transactions. Accordingly, in the restated consolidated financial statements as of December 31, 2012, the Company decreased income tax payable by $177 and increased additional paid-in capital by $506.

Acquisitions	'
	Acquisition
	For all acquisitions, the Company allocates the purchase price to the estimated fair values of the assets acquired and liabilities assumed as of the date of the acquisition. The market approach, which indicates value based on available market pricing for comparable assets, is utilized to estimate the fair value of inventory, property and equipment. The income approach, which indicates value based on the present value of future cash flows, is primarily used to value intangible assets. The cost approach, which estimates values by determining the current cost of replacing an asset with another of equivalent utility, is used, as appropriate, for certain assets for which the market and income approaches could not be applied due to the nature of the asset.
	Chesapeake Structural Systems
	On April 8, 2013, Commonwealth Acquisition Holdings, LLC, a wholly-owned subsidiary of the Company, purchased certain assets and assumed certain liabilities of Chesapeake Structural Systems, Inc., Creative Wood Products, LLC and Chestruc, LLC (collectively “Chesapeake”) for an adjusted purchase price of $2,623. This amount includes an initial holdback amount of $250 due to the sellers on April 8, 2014. The holdback amount may be reduced under certain circumstances, including the Company’s inability to collect upon acquired accounts receivable. The acquisition provides the Company with component manufacturing capability to serve customers in the Central and Northern Virginia markets. The Company incurred transaction costs of $0 and $151 during the three months and nine months ended September 30, 2013, respectively, which are included in selling, general and administrative expenses on the consolidated statements of operations. Net sales of Chesapeake for the period from April 8, 2013 through September 30, 2013 were $5,347. The impact of this acquisition on our operating results was not considered material for the reporting of pro forma financial information.
	Intangible assets of $1,160 acquired from Chesapeake consist of customer relationships and have an amortization period of 13 years.
	Goodwill of $675 arising from the acquisition consists of expected synergies and cost savings from excess purchase price over identifiable intangible net assets, as well as intangible assets that do not qualify for separate recognition, such as assembled workforce. All of the goodwill from this transaction is expected to be deductible for income tax purposes.

	Discontinued operations
	During 2012, the Company ceased operations in certain geographic markets due to declines in residential home building throughout the U.S. and other strategic reasons. The Company will have no further significant continuing involvement in the sold operations and exited geographic markets. The cessation of operations in these markets has been treated as discontinued operations as the markets had distinguishable cash flows and operations that have been eliminated from ongoing operations.
	The operating results of the discontinued operations for the three and nine months ended September 30, 2013 and 2012 are as follows:

Restructuring costs	'
	Restructuring costs
	In addition to discontinuing operations in certain markets, the Company has instituted store closures and reductions in headcount in continuing markets (the “Restructurings”) in an effort to: (i) strengthen the Company’s competitive position; (ii) reduce costs and (iii) improve operating margins within existing markets that management believes have favorable long-term growth demographics.
	No additional costs, other than interest accretion, are expected to be incurred related to the Restructurings.
	The following table summarizes the restructuring expenses incurred in connection with the Restructurings and the remaining reserves as of September 30, 2013:
		Work force			Store			Total
		reductions			closures

	Restructuring reserves, September 30, 2013	$	237		$	3,755		$	3,992
	The remaining accrual for work force reduction of $237 is expected to be fully paid by December 2014. The remaining accrual for store closures of $3,755 is expected to be fully paid by January 2017 as the related leases expire.
	The restructuring reserve at September 30, 2013 consists of a current portion of $1,572 and a long-term portion of $2,420, which is included in other long-term liabilities on the consolidated balance sheets.

	Goodwill
	The following table shows changes in goodwill for the nine months ended September 30, 2013. All of the Company's goodwill as of September 30, 2013 is recorded in the geographic divisions reportable segment (Note 15):
	31-Dec-12	$	6,511
	Acquisition of Chesapeake (Note 5)	675
	30-Sep-13	$	7,186
	The Company performs its annual impairment assessment of goodwill during the third quarter of each year, or at any other time when impairment indicators exist. To the extent that the carrying value of the net assets of any of the reporting units having goodwill is greater than their estimated fair value, the Company may be required to take goodwill impairment charges. The Company’s reporting units are its East, South and West geographic divisions and Coleman Floor.
	For purposes of testing goodwill, the Company estimates fair value using the income approach. The income approach uses a reporting unit’s projection of estimated future cash flows that is discounted at a market derived weighted average cost of capital. The projection uses management’s best estimates of economic and market conditions over the projected period including growth rates in sales, costs, estimates of future expected changes in operating margins and cash expenditures.
	The annual impairment assessment performed by the Company during the third quarter of 2013 and 2012 did not indicate that an impairment existed. During each assessment, the Company determined that the fair value of its reporting units containing goodwill exceeded their carrying value.

	(a)	Base Rate is the higher of (i) the Federal Funds Rate plus 0.5% or (ii) the prime rate.
	(b)	The Revolver’s borrowing base is calculated as the sum of (i) 85% of the Company’s eligible accounts receivable plus (ii) the lesser of 90% of the eligible credit card receivables and $5,000, plus (iii) the lesser of $125,000, 65% of the eligible inventory or 85% of the net liquidation value of eligible inventory as defined in the Credit Agreement minus (iv) reserves from time to time set by the administrative agent. The eligible accounts receivable and inventories are further adjusted as specified in the Credit Agreement. The Company’s borrowing base can also be increased pursuant to certain terms outlined in the Credit Agreement.
	The Credit Agreement provides that the Company can use the Revolver availability to issue letters of credit. The fees on any outstanding letters of credit issued under the Revolver include a participation fee equal to the LIBOR Rate Margin. The fee on the unused portion of the Revolver is 0.375% if the average daily usage is $75,000 or below, and 0.25% if the average daily usage is above $75,000. The Revolver includes a financial covenant that requires the Company to maintain a minimum Fixed Charge Coverage Ratio of 1.00:1.00 as defined by the Credit Agreement. The Fixed Charge Coverage Ratio requirement is only applicable if adjusted liquidity is less than $15,000, and remains in effect until the date on which adjusted liquidity has been greater than or equal to $15,000 for a period of 30 consecutive days. Adjusted liquidity is defined as the sum of (i) availability under the Revolver and (ii) qualified cash. The Company has incurred operating losses and has used cash for operating activities for the nine months ended September 30, 2013 and 2012. While there can be no assurances, based upon the Company’s forecast, the Company does not expect the financial covenants to become applicable during the year ended December 31, 2013.
	The Company had outstanding borrowings of $60,073 and $72,218 with net availability of $81,527 and $31,344 as of September 30, 2013 and December 31, 2012, respectively. The interest rate on outstanding LIBOR Rate borrowings of $51,000 was 2.3% and the interest rate on outstanding Base Rate borrowings of $9,073 was 4.25% as of September 30, 2013. The interest rate on outstanding LIBOR Rate borrowings of $65,000 ranged from 3.1%-3.3% and the interest rate on outstanding Base Rate borrowings of $7,218 was 5.0% as of December 31, 2012. The Company had $8,400 and $7,550 in letters of credit outstanding under the Credit Agreement as of September 30, 2013 and December 31, 2012, respectively. The Revolver is collateralized by substantially all assets of the Company. The carrying value of the Revolver at September 30, 2013 and December 31, 2012 approximates fair value as the Revolver contains a variable interest rate. As such, the fair value of the Revolver was classified as a Level 2 measurement in accordance with ASC 820.
	The Revolver is classified as a long-term liability as of September 30, 2013 as the Company is no longer required to maintain a lockbox sweep arrangement with WFCF, due to net availability exceeding a minimum threshold defined in the Credit Agreement.

	On February 22, 2010, the Company entered into a Software, Services, License and Maintenance Services Agreement with United Road Services Inc. and its subsidiary Vehix Transvision, LLC (collectively “URS”) for the development, implementation, maintenance and support of customized software related to our Stock Logistics Solutions capability. The agreement with URS was subsequently amended and restated on March 3, 2013 to update certain services and deliverables. When we entered into the original agreement in 2010, URS was also owned by Gores as one of its portfolio companies. Gores divested its ownership interest in URS on December 14, 2012 and URS is no longer under common ownership with the Company. Accordingly, the Company does not consider URS a related party subsequent to December 14, 2012. The Company paid URS $194 and $578 during the three and nine months ended September 30, 2012, respectively.
	During the three and nine months ended September 30, 2013 and 2012, the Company incurred expenses related to management services provided by Gores and Glendon Saturn Holdings, LLC, an affiliate of Gores. For the three months ended September 30, 2013 and 2012 and nine months ended September 30, 2013 and 2012, these expenses were $239, $330, $1,205 and $1,097, respectively, and are included in selling, general and administrative expenses on the consolidated statements of operations. The management services agreement with Gores was terminated on August 14, 2013 in connection with the IPO, and the Company paid Gores a $9,000 termination fee on that date (Note 2).
	Prior to July 1, 2013, the Company was part of a group health care plan with Gores. As of September 30, 2013 and December 31, 2012, the Company had $83 and $750, respectively, on deposit with Gores as a reserve for the payment of run-off health care claims in the event of a Plan termination, which is included in restricted assets on the consolidated balance sheets. As of July 1, 2013, the Company is no longer part of the group health care plan with Gores and maintains an independent health care plan.

	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 recognized valuation allowances of $2,147 and $1,946 against its deferred tax assets related to certain tax jurisdictions as of September 30, 2013 and December 31, 2012, respectively.
	During the three and nine months ended September 30, 2013, the Company recorded additional valuation allowances of $185 and $201, respectively, against deferred tax assets related to our continuing operations. During the three and nine months ended September 30, 2012, the Company recorded additional valuation allowances of $163 and $543, respectively, against deferred tax assets related to our continuing operations. To the extent the Company generates sufficient taxable income in the future to utilize the tax benefits of the net deferred tax assets on which a valuation allowance is recorded, the effective tax rate may decrease as the valuation allowance is reversed. As of September 30, 2013, the Company is no longer able to carry back its tax net operating losses; therefore, to the extent the Company generates future tax net operating losses, the Company may be required to increase the valuation allowance on net deferred tax assets and income tax benefit would be adversely affected.
	For the three and nine months ended September 30, 2013, the Company’s effective income tax rate including discontinued operations and other discrete items was (58.9)% and (20.9)%, respectively, which varied from the federal statutory rate of 35% primarily due to non-deductibility of the termination fee of $9,000 related to our management services agreement with Gores and certain capitalized costs. For the three and nine months ended September 30, 2012, the Company’s effective income tax rate including discontinued operations and other discrete items was 121.5% and 35.5%, respectively, which varied from the federal statutory rate of 35% primarily due to state income tax expense and valuation allowance.
	The effective income tax rate on continuing operations for the three months ended September 30, 2013 was (55.0)% compared to an effective income tax rate on continuing operations of 61.3% for the three months ended September 30, 2012. The effective income tax rate on continuing operations for the nine months ended September 30, 2013 was (15.7)% compared to an effective income tax rate on continuing operations of 35.5% for the nine months ended September 30, 2012. The decrease in the tax rates for the comparative three-month and nine-month periods is primarily due to the domestic manufacturing deduction tax benefit, which was not available in the prior year due to the Company’s tax operating loss position, changes to the valuation allowance against the Company’s deferred tax assets, the non-deductibility of the termination fee related to our management services agreement with Gores and the capitalization of certain costs.
	The Company has no material uncertain tax positions as of September 30, 2013 and December 31, 2012.

	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, product 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 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.

	ASC 280, Segment Reporting (“ASC 280”) 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 in deciding how to allocate resources and in assessing performance.
	Our operating segments consist of the East, South, and West divisions along with Coleman Floor, which offers professional flooring installation services. Due to the similar economic characteristics, nature of products, distribution methods and customers, we have aggregated our East, South and West operating segments into one reportable segment, "Geographic divisions."
	In addition to our reportable segment, the Company's consolidated results include "Coleman Floor" and "Other reconciling items," which is comprised of our corporate activities.

Earnings Per Share [Abstract]	'
Income (loss) per common share	'
	Income (loss) per common share
	Basic net income (loss) per share (“EPS”) is calculated by dividing net income (loss) 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 common share equivalents outstanding for the period, determined using the treasury-stock method. For purposes of the diluted EPS calculation, stock options and nonvested stock awards are considered to be common stock equivalents. Convertible Class C Preferred shares are considered to be participating securities. During periods of net income, participating securities are allocated a proportional share of net income determined by dividing total weighted average participating securities by the sum of total weighted average common shares and participating securities (“the two-class method”). During periods of net loss, no effect is given to participating securities since they do not share in the losses of the Company.
	The basic and diluted EPS calculations for the three months and nine months ended September 30, 2013 and 2012 are presented below:

	The 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, 2012 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 most recent audited annual financial statements. 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.
