These transactions included a repricing and extension of our Term Loan Amendment On February 23, 2017, we repriced our 2015 term loan through an amendment and extension of the term loan credit agreement providing for a $467.7 million senior secured term loan facility due 2024 (“2024 term loan”). This repricing reduces the interest rate by 0.75% and extends the maturity by 19 months to February 29, 2024. The 2024 term loan bears interest based on either a eurodollar or base rate (a rate equal to the highest of an agreed commercially available benchmark rate, the federal funds effective rate plus 0.50% or the eurodollar rate plus 1.0%, as selected by the Company) plus, in each case, an applicable margin. The applicable margin in the 2024 term loan is (x) 3% in the case of Eurodollar rate loans and (y) 2% in the case of base rate loans. These rates represents a 0.75% reduction from the 2015 term loan. Deutsche Bank AG New York Branch continues to serve as administrative agent and collateral agent under the 2024 term loan agreement. In connection with the 2024 term loan amendment we recognized $0.4 million in interest expense in the first quarter of 2017 related to the write-off of unamortized debt discount and debt issuance costs. We incurred $1.2 million in lender fees which, together with $10.0 million in remaining unamortized debt discount and debt issuance costs, have been recorded as a reduction of long-term debt and are being amortized over the remaining contractual life of the 2024 term loan using the effective interest method. In addition, we also incurred $1.4 million in various third-party fees and expenses related to the 2024 term loan amendment which were recorded to interest expense in the first quarter of 2017. Revolving Credit Facility Amendment On March 22, 2017, the Company extended the maturity date and increased the revolving commitments under its 2015 facility. This transaction resulted in an amended and restated $900.0 million revolving credit facility (“2022 facility”) and extended the maturity by 20 months to March 22, 2022. SunTrust Bank continues to serve as administrative agent and collateral agent under the 2022 facility agreement. All other material terms of the 2022 facility remain unchanged from those of the 2015 facility. In connection with the 2022 facility amendment, we recognized $0.6 million in interest expense in the first quarter of 2017 related to the write-off of unamortized debt issuance costs. We incurred $1.6 million in lender and third-party fees which, together with $8.5 million in remaining unamortized debt issuance costs, have been recorded as other assets and are being amortized over the remaining contractual life of the 2022 facility on a straight-line basis. 2022 Facility Borrowings As of September 30, 2017, we have $55.0 million in borrowings outstanding under our 2022 facility. During the first nine months of 2017, we borrowed $894.0 million and repaid $839.0 million at a weighted average interest rate of 2.9%. 2024 Term Loan As of September 30, 2017, we have $464.1 million in borrowings outstanding under our 2024 term loan at a weighted average interest rate of 4.3%. During the first nine months of 2017, we repaid $3.5 million of the 2024 term loan. We were not in violation of any covenants or restrictions imposed by any of our debt agreements at September 30, 2017. Fair Value As of September 30, 2017 and December 31, 2016, the Company does not have any financial instruments which are measured at fair value on a recurring basis. We have elected to report the value of our 2023 notes, 2024 notes, and 2024 term loan at amortized cost. The fair values of the 2023 notes, the 2024 notes and the 2024 term loan at September 30, 2017 were approximately $419.5 million, $794.4 million and $465.9 million, respectively, and were determined using Level 2 inputs based on market prices.

Employee Stock-Based Compensation	4. Employee Stock-Based Compensation Time Based Restricted Stock Unit Grants In the first nine months of 2017, our board of directors granted 453,000 RSUs to employees and eligible directors under our 2007 and 2014 Incentive Plans for which vesting is based solely on continuous employment over the requisite service period. 348,000 of the RSUs vest at 33% per year at each anniversary of the grant date over the next three years, 57,000 RSUs vest at 25% per year at each anniversary of the grant date over the next four years and 48,000 RSUs vest 100% at the first anniversary of the grant date. The weighted average grant date fair value for these RSUs was $14.47 per share, which was based on the closing stock price on the grant dates. Performance and Service Condition Based Restricted Stock Unit Grants In the first nine months of 2017, our board of directors granted 174,000 RSUs to employees under our 2007 and 2014 Incentive Plans, that vest if the compound annual growth rate of the Company’s total sales in 2019 over 2016 exceeds a composite annual growth rate based on single-family housing starts, multi-family housing starts, and growth in repair and remodeling sales over the same period. Assuming continued employment and if the performance vesting condition is achieved, these awards will cliff vest on the third anniversary of the grant date. The weighted average grant date fair value for these RSUs was $14.54 per share, which was based on the closing stock price on the grant dates. Market and Service Condition Based Restricted Stock Unit Grants In the first nine months of 2017, our board of directors granted 174,000 RSUs to employees under our 2007 and 2014 Incentive Plans for which vesting is contingent upon the Company’s total shareholder return exceeding the median total shareholder return of the Company’s peer group over a three year measurement period. Assuming continued employment and if the market vesting condition is met, these awards will cliff vest on the third anniversary of the grant date. The weighted average grant date fair value for these RSUs was $11.49 per share, which was determined using the Monte Carlo simulation model using the following weighted average assumptions: Expected volatility (company) 73.7% Expected volatility (peer group median) 33.8% Correlation between the company and peer group median 0.33 Expected dividend yield 0.00% Risk-free rate 1.5% The expected volatilities and correlation are based on the historical daily returns of our common stock and the common stocks of the constituents of the Company’s peer group over the most recent period equal to the measurement period. 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 measurement period. Stock Option Grant In the first nine months of 2017, our board of directors granted 57,000 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 $12.94 per share, which was the closing stock price on the grant date. The weighted average grant date fair value of the options was $7.26 and was determined using the Black-Scholes option-pricing model with the following weighted average assumptions: Expected life 6.0 years Expected volatility 59.2% Expected dividend yield 0.00% Risk-free rate 2.2% 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.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	5. Income Taxes A reconciliation of the statutory federal income tax rate to our effective rate for continuing operations is provided below: Three Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 Statutory federal income tax rate 35.0 % 35.0 % 35.0 % 35.0 % State income taxes, net of federal income tax 8.1 2.6 6.5 6.1 Valuation allowance (0.3 ) 2,126.5 (3.3 ) (849.1 ) Stock compensation windfall benefit (1.7 ) — (2.6 ) — Permanent differences (13.6 ) 14.1 (5.7 ) (2.3 ) Other — 1.5 0.2 (0.6 ) 27.5 % 2,179.7 % 30.1 % (810.9 )% As discussed in Note 1 the Company adopted updated guidance related to the accounting for stock compensation in the first quarter of 2017. As a result of this updated guidance all windfalls or shortfalls are now recognized as a component of income tax expense in the period they occur. We evaluate our deferred tax assets on a quarterly basis to determine whether a valuation allowance is required. In accordance with the Income Taxes We recorded a full valuation allowance in 2008 due to our cumulative three year loss position at that time, compounded by the negative industry-wide business trends and outlook. We remained in a cumulative three year loss position until the second quarter of 2016. In the third quarter of 2016, management determined that there was sufficient positive evidence to conclude that it was more likely than not that the valuation allowance should be released against our net federal and some state deferred tax assets. Further, during the second quarter of 2017, as a result of executing certain tax planning strategies related to legal entity conversions, we determined that it was more likely than not that we will utilize almost all of our state net operating loss carryovers. Therefore, we recorded reductions to the associated valuation allowance of $0.1 million and $3.8 million for the three and nine months ended September 30, 2017, respectively. We recorded reductions to the valuation allowance of $117.6 million and $128.6 million for the three and nine months ended September 30, 2016, respectively, against our net deferred tax assets as we released valuation allowances against our federal and some state deferred tax assets. Section 382 of the Internal Revenue Code 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”). In the first nine months of 2017, affiliates of a significant shareholder sold their investment in the Company, which triggered a Section 382 Ownership Change. As a result of triggering a Section 382 Ownership Change, an annual limitation is now imposed on the Company’s tax attributes, including its NOLs and other credits. The Company has evaluated the impact of this limitation on its Federal NOLs and does not expect it to have a material impact on the future utilization or realizability of its Federal NOLs. While the Company is still evaluating the impact of this limitation on its other attributes, we do not expect it to have a material impact on the future utilization or realizability of its other attributes. 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	6. Commitments and Contingencies Since the fourth quarter of 2016, the Company has seen an increased occurrence of known and threatened construction defect legal claims primarily in two states. While these claims are generally covered under the Company’s existing insurance programs to the extent any loss exceeds the deductible, there is a reasonable possibility of loss that is not able to be estimated at this time because (i) many of the proceedings are in the discovery stage, (ii) the outcome of future litigation is uncertain, and/or (iii) the complex nature of the claims. Although the Company cannot estimate a reasonable range of loss based on currently available information, the resolution of these matters could have a material adverse effect on the Company's financial position, results of operations or cash flows. In addition, we are involved in various other claims and lawsuits incidental to the conduct of our business in the ordinary course. We carry insurance coverage in such amounts in excess of our self-insured retention as we believe to be reasonable under the circumstances and that may or may not cover any or all of our liabilities in respect of such claims and lawsuits. Although the ultimate disposition of these other proceedings cannot be predicted with certainty, management believes the outcome of any such claims that are 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 adverse judgments and costs would not be material to our results of operations or liquidity for a particular period.

Segment Reporting [Abstract]
Segment and Product Information	7. 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 402 locations operating in 40 states across the United States, which are organized into nine geographical regions. Centralized financial and operational oversight, including resource allocation and assessment of performance on an income (loss) before income taxes basis, is performed by our CEO, whom we have determined to be our chief operating decision maker (“CODM”). The Company has nine operating segments aligned with its nine geographical regions (Regions 1 through 9). While all of our operating segments have products, distribution methods and customers of a similar nature, 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 as a single unit 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 referenced in Note 1, except for noted reconciling items. The following tables present Net sales, income (loss) before income taxes and certain other measures for the reportable segments, reconciled to consolidated total continuing operations, for the periods indicated (in thousands): Three months ended September 30, 2017 Reportable segments Net Sales Depreciation & Amortization Interest Income (loss) before income taxes Northeast $ 341,188 $ 3,233 $ 5,442 $ 11,875 Southeast 388,881 2,689 6,064 10,661 South 463,562 4,953 5,883 21,513 West 635,573 6,599 8,610 34,207 Total reportable segments 1,829,204 17,474 25,999 78,256 All other 49,705 5,557 7,837 (23,408 ) Total consolidated $ 1,878,909 $ 23,031 $ 33,836 $ 54,848 Three months ended September 30, 2016 Reportable segments Net Sales Depreciation & Amortization Interest Income (loss) before income taxes Northeast $ 328,529 $ 4,009 $ 5,058 $ 10,613 Southeast 356,694 2,626 5,452 9,829 South 451,342 5,048 5,859 20,078 West 563,718 7,747 7,172 30,656 Total reportable segments 1,700,283 19,430 23,541 71,176 All other 45,675 6,122 68,749 (77,209 ) Total consolidated $ 1,745,958 $ 25,552 $ 92,290 $ (6,033 ) Nine months ended September 30, 2017 Reportable segments Net Sales Depreciation & Amortization Interest Income (loss) before income taxes Northeast $ 949,484 $ 10,185 $ 15,694 $ 26,665 Southeast 1,132,598 7,882 17,254 35,079 South 1,394,513 14,683 17,605 67,996 West 1,633,851 20,663 23,774 67,701 Total reportable segments 5,110,446 53,413 74,327 197,441 All other 144,824 17,383 29,376 (80,842 ) Total consolidated $ 5,255,270 $ 70,796 $ 103,703 $ 116,599 Nine months ended September 30, 2016 Reportable segments Net Sales Depreciation & Amortization Interest Income (loss) before income taxes Northeast $ 912,314 $ 14,897 $ 13,817 $ 25,677 Southeast 1,027,283 8,930 14,518 29,479 South 1,284,466 16,930 16,700 55,737 West 1,472,509 27,133 20,382 57,905 Total reportable segments 4,696,572 67,890 65,417 168,798 All other 123,800 19,011 104,899 (153,656 ) Total consolidated $ 4,820,372 $ 86,901 $ 170,316 $ 15,142 Asset information by segment is not reported internally or otherwise reviewed by the CODM nor does the Company earn revenues or have long-lived assets located in foreign countries.
