In the opinion of management, all adjustments (consisting of normal recurring adjustments and accruals) necessary to present fairly the financial position at March 31, 2013 and December 31, 2012, the results of operations, comprehensive income, and cash flows for the three months ended March 31, 2013 and 2012, and the statement of shareholders' equity for the three months ended March 31, 2013 have been included therein in accordance with U.S. Securities and Exchange Commission (SEC) rules and regulations and prepared using the same accounting principles as are used for our annual audited financial statements. Certain information and footnote disclosures, including significant accounting policies normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America, have been condensed or omitted in accordance with the prescribed SEC rules. It is suggested that these consolidated financial statements be read in conjunction with the consolidated financial statements and footnotes included in the Company's Annual Report for the year ended December 31, 2012 as filed on Form 10-K. The consolidated balance sheet at December 31, 2012 has been derived from the audited consolidated financial statements at that date, restated for discontinued operations, but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. The results of operations for the three month period ended March 31, 2013 are not necessarily indicative of the results to be expected for the full year.

Recent Accounting Pronouncements	Mar. 31, 2013
Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	2. RECENT ACCOUNTING PRONOUNCEMENTS In February 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2013-02, "Comprehensive Income (Topic 220) – Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income." The amendments in this Update require a company to report the effect of significant reclassifications out of accumulated other comprehensive income (AOCI) on the respective line items in net income if the amount is required by U.S. GAAP to be reclassified in its entirety to net income. For amounts not required under U.S. GAAP to be reclassified in their entirety, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2012 and are to be applied prospectively. The Company adopted Update 2013-02 prospectively in 2013 and its adoption does not have a material impact on the Company's consolidated financial statements. In March 2013, the FASB issued Accounting Standards Update 2013-05, "Foreign Currency Matters (Topic 830) –Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity." The amendments in this Update require a company to release the cumulative translation adjustment into net income upon the loss of a controlling financial interest in a foreign subsidiary or group of assets. The amendments are effective prospectively beginning after December 15, 2013, and early adoption is permitted. The Company does not expect the adoption of Update 2013-05 to have a material impact of the Company's consolidated financial results.

- Definition

The entire disclosure of changes in accounting principles, including adoption of new accounting pronouncements, that describes the new methods, amount and effects on financial statement line items.

Acquisitions

4. ACQUISITIONS

During 2012, Gibraltar purchased the assets of four businesses in separate transactions, one of which occurred during the first quarter of 2012. The acquired product lines complement and expand the Company's product portfolio and customer base in four key U.S. and Canadian markets:

Metal grating products for the oil sands region of Western Canada;
Function-critical components for public infrastructure construction and maintenance;
Perforated metal products for industrial applications; and
Exterior, retractable awnings and sun protection accessory products for new residential construction and home remodeling.

Gibraltar funded the aggregate investment of $43,117,000 from existing cash on hand. The purchase price for each acquisition was allocated to the assets acquired and liabilities assumed based upon their respective fair values. The excess consideration was recorded as goodwill and totaled $15,240,000, all of which is deductible for tax purposes. Goodwill represents future economic benefits arising from other assets acquired that could not be individually identified including growth opportunities and increased presence in the building products markets.

The allocation of purchase consideration to the assets acquired and liabilities assumed during 2012 are as follows (in thousands):


Working capital		8,745
Property, plant, and equipment		9,682
Acquired intangible assets		10,183
Other liabilities		(733	)
Goodwill		15,240
Fair value of purchase consideration	$	43,117

The acquired intangible assets consisted of the following for the four acquisitions completed during the year ended December 31, 2012 (in thousands):


			Estimated
		Fair Value	Useful Life
Customer relationships		4,480	5-15 Years
Unpatented technology and patents	$	2,313	15 Years
Trademarks		2,110	Indefinite
Amortizable trademarks		800	5 Years
Non-compete agreements		350	5-10 Years
Backlog		130	0.5 Years
Total	$	10,183

The Company incurred certain acquisition-related costs, primarily composed of legal and consulting fees of $117,000, and $80,000 for the three months ended March 31, 2013 and 2012, respectively. All acquisition related costs were recognized as a component of selling, general and administrative expenses on the consolidated statement of operations. The Company also recognized additional cost of sales of $203,000 and $60,000 for the three months ended March 31, 2013 and 2012, respectively, related to the recognition of inventory at fair value when allocating the purchase price of the acquisitions.

Borrowings under the Senior Credit Agreement are secured by the trade receivables, inventory, personal property, equipment, and certain real property of the Company's significant domestic subsidiaries. The Senior Credit Agreement is also guaranteed by each of the Company's significant domestic subsidiaries. The Senior Credit Agreement provides for a revolving credit facility and letters of credit in an aggregate amount that does not exceed the lesser of (i) $200 million and (ii) a borrowing base determined by reference to the trade receivables, inventories, and property, plant, and equipment of the Company's significant domestic subsidiaries. The Company can request additional financing from the banks to increase the revolving credit facility to $250 million under the terms of the Senior Credit Agreement.

The terms of the Senior Credit Agreement provide that the revolving credit facility will terminate on October 10, 2016. Interest rates on the revolving credit facility are based on the London Interbank Offering Rate (LIBOR) plus an additional margin of 2.0% to 2.5%. In addition, the revolving credit facility is subject to an annual commitment fee calculated as 0.375% of the daily average undrawn balance.

Standby letters of credit of $13,592,000 have been issued under the Senior Credit Agreement to third parties on behalf of the Company as of March 31, 2013. These letters of credit reduce the amount otherwise available under the revolving credit facility. As of March 31, 2013, the Company had $135,227,000 of availability under the revolving credit facility.

On a trailing four-quarter basis, the Senior Credit Agreement includes a single financial covenant that requires the Company to maintain a minimum fixed charge coverage ratio of 1.25 to 1.00 at the end of each quarter. As of March 31, 2013, the Company was in compliance with this financial covenant. The Senior Credit Agreement contains other provisions and events of default that are customary for similar agreements and may limit the Company's ability to take various actions.

On January 31, 2013, the Company issued $210.0 million of 6.25% Senior Subordinated Notes (6.25% Notes) due February 1, 2021. In connection with the issuance of the 6.25% Notes, the Company initiated a tender offer for the purchase of the outstanding $204.0 million of 8% Senior Subordinated Notes (8% Notes). Simultaneously with the closing of the sale of the 6.25% Notes, the Company purchased tendered notes or called for redemption of all of the remaining 8% Notes that were not purchased. In connection with the redemption and tender offer, the Company satisfied and discharged its obligations under the 8% Notes during the three months ended March 31, 2013. The Company recorded a charge of approximately $7.2 million in the first quarter of 2013, including $3.7 million for the prepayment premium paid to holders of the 8% Notes, $2.2 million to write-off deferred financing fees and $1.3 million for the unamortized original issue discount related to the 8% Notes.

The provisions of the 6.25% Notes include, without limitation, restrictions on indebtedness, liens, and distributions from restricted subsidiaries, asset sales, affiliate transactions, dividends, and other restricted payments. Dividend payments are subject to annual limits of the greater of $0.25 per share or $25 million. The 6.25% Notes are redeemable at the option of the Company, in whole or in part, at any time on or after February 1, 2017, at the redemption price (as defined in the Senior Subordinated 6.25% Notes Indenture). The redemption prices are 103.13%, and 101.56% of the principal amount thereof if the redemption occurs during the 12-month periods beginning February 1, of the years 2017 and 2018, respectively, and 100% of the principal amount thereof on and after February 1, 2019, in each case plus accrued and unpaid interest to the applicable redemption date. In addition, prior to February 1, 2016, the Company may redeem up to 35% of the aggregate principal amount of the Notes with the net cash proceeds of certain equity offerings by the Company at a redemption price of 106.25% of the principal amount thereof, plus accrued and unpaid interest to the redemption date. In the event of a Change in Control, each holder of the 6.25% Notes may require the Company to repurchase all or a portion of such holder's 6.25% Notes at a purchase price equal to 101% of the principal amount thereof.

Equity-Based Compensation

3 Months Ended

Mar. 31, 2013

Equity-Based Compensation [Abstract]

Equity-Based Compensation

9. EQUITY-BASED COMPENSATION

Equity-based payments to employees and directors, including grants of stock options, restricted stock units, and restricted stock, are recognized in the statements of operations based on the grant-date fair value of the award. The Company uses the straight-line method of attributing the value of stock-based compensation expense over the vesting periods. Stock compensation expense recognized during the period is based on the value of the portion of equity-based awards that is ultimately expected to vest during the period. Vesting requirements vary for directors, executives, and key employees with a vesting period that typically equals four years with graded vesting.

The Gibraltar Industries, Inc. 2005 Equity Incentive Plan (the Plan) is an incentive compensation plan that allows the Company to grant equity-based incentive compensation awards to eligible participants to provide them an additional incentive to promote the business of the Company, to increase their proprietary interest in the success of the Company, and to encourage them to remain in the Company's employ. Awards under the plan may be in the form of options, restricted shares, restricted units, performance shares, performance stock units, and rights. The Plan provides for the issuance of up to 3,000,000 shares of common stock. Of the total number of shares of common stock issuable under the Plan, the aggregate number of shares which may be issued in connection with grants of incentive stock options and rights cannot exceed 900,000 shares. Vesting terms and award life are governed by the award document.

The following table provides the number of restricted stock units (that will convert to shares upon vesting), that were issued during the three months ended March 31 along with the weighted average grant date fair value of each award:


		2013			2012
			Weighted		Weighted
			Average			Average
	Number of	Grant Date		Number of	Grant Date
Awards	Awards	Fair Value		Awards	Fair Value
Restricted stock units	72,165	$	16.50	74,532	$	14.36

In January 2012, the Company awarded 295,000 performance stock units with grant date fair value of $4,152,000. As of March 31, 2013, 280,000 of the originally awarded performance stock units remained outstanding after forfeitures. The final number of performance stock units earned was based on the Company's total stockholder returns relative to the S&P Small Cap 600 Index for the calendar year of 2012. During the performance period, the participants earned 58.3% of target, aggregating 163,200 performance stock units compared to the target of 280,000 awards.

In January 2013, the Company awarded 303,917 performance stock units with grant date fair value of $4,123,000, all of which remain outstanding as of March 31, 2013. The final number of performance stock units earned will be determined based on the Company's actual return on invested capital (ROIC) for 2013.

The cost of the 2012 and 2013 performance stock awards will be recognized over the requisite service period, which ranges between one year and three years, depending on the date a participant turns 60 and completes 5 years of service. After the vesting period, any performance stock units earned will convert to cash based on the trailing 90-day closing price of the Company's common stock as of December 31, 2014 and 2015 and be payable to participants in January 2015 and 2016, respectively.

The following table summarizes the compensation expense recognized for the performance stock units for the three months ended March 31 (in thousands):


		2013		2012
Performance stock unit compensation expense	$	1,501	$	679

The Management Stock Purchase Plan (MSPP) is an integral component of the Plan and provides participants the ability to defer a portion of their salary, their annual bonus under the Management Incentive Compensation Plan, and Directors' fees. The deferral is converted to restricted stock units and credited to an account together with a company-match in restricted stock units equal to a percentage of the deferral amount. The account is converted to cash at the trailing 200-day average closing price of the Company's stock and payable to the participants upon a termination of their service to the Company. The matching portion vests only if the participant has reached their sixtieth (60^th) birthday. If a participant terminates their service to the Company prior to age sixty (60), the match is forfeited. Upon termination, the account is converted to a cash account that accrues interest at 2% over the then current ten-year U.S. Treasury note rate. The account is then paid out in either one lump sum, or in five or ten equal annual cash installments at the participant's election.

The fair value of restricted stock units held in the MSPP equals the trailing 200-day average closing price of the Company's common stock as of the last day of the period. During the three months ended March 31, 2013 and 2012, 183,178 and 222,551 restricted stock units, respectively, including the company-match, were credited to participant accounts. At March 31, 2013 and December 31, 2012, the value of the restricted stock units in the MSPP was $13.64 and $12.30 per unit, respectively. At March 31, 2013 and December 31, 2012, 960,357 and 777,159 restricted stock units, including the company-match, were credited to participant accounts including 93,490 and 71,992, respectively, of unvested restricted stock units. The Company made disbursements of $531,000 and $542,000 out of the MSPP during the three months ended March 31, 2013 and 2012, respectively.

Fair Value Measurements	3 Months Ended
Fair Value Measurements	Mar. 31, 2013
Fair Value Measurements [Abstract]
Fair Value Measurements	10. FAIR VALUE MEASUREMENTS FASB Accounting Standards Codification (ASC) Topic 820, "Fair Value Measurements and Disclosures," defines fair value, sets out a framework for measuring fair value, and requires certain disclosures about fair value measurements. A fair value measurement assumes that the transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability. Fair value is defined based upon an exit price model. FASB ASC Topic 820 establishes a valuation hierarchy for disclosure of the inputs used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company's assumptions used to measure assets and liabilities at fair value. A financial asset or liability's classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. As described in Note 4 of the consolidated financial statements, the Company completed four acquisitions during the year ended December 31, 2012. The estimated fair values allocated to the assets acquired and liabilities assumed relied upon fair value measurements based in part on Level 3 inputs. The valuation techniques used to assign fair values to inventory, property, plant and equipment, and intangible assets included the cost approach, market approach, relief-from-royalty approach, and other income approaches. The valuation techniques relied on a number of inputs which included the cost and condition of the property, plant and equipment, forecasted net sales and incomes, and royalty rates. The Company's financial instruments primarily consist of cash and cash equivalents, accounts receivable, accounts payable, and long-term debt. The carrying values for our financial instruments approximate fair value with the exception, at times, of long-term debt. At March 31, 2013, the fair value of outstanding debt was $227,286,000 compared to its carrying value of $214,423,000. The fair value of the Company's Senior Subordinated 6.25% Notes was estimated based on quoted market prices, a Level 1 input.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Exit Activity Costs And Asset Impairments [Abstract]

Exit Activity Costs And Asset Impairments

12. EXIT ACTIVITY COSTS AND ASSET IMPAIRMENTS

The Company focuses on being the low-cost provider of its products by reducing operating costs and implementing lean manufacturing initiatives, which have in part led to the consolidation of facilities and product lines. The Company consolidated two facilities during 2012 in this effort. During this process, the Company has incurred exit activity costs, including contract termination costs, severance costs, and other moving and closing costs. These restructuring activities also resulted in $1,037,000 of asset impairment charges related to the facility consolidations during the three months ended March 31, 2012.

The following table provides a summary of where the exit activity costs and asset impairments were recorded in the statement of operations for the three months ended March 31 (in thousands):


		2013		2012
Cost of sales	$	29	$	1,766
Selling, general, and administrative expense		–		14
Total exit activity costs and asset impairments	$	29	$	1,780

The following table reconciles the beginning and ending liability for exit activity costs relating to the Company's facility consolidation efforts (in thousands):


		2013			2012

Income Taxes	3 Months Ended
Income Taxes	Mar. 31, 2013
Income Taxes [Abstract]
Income Taxes	13. INCOME TAXES The Company's provision for income taxes in interim periods is computed by applying forecasted annual effective tax rates to income or loss before income taxes for the interim period. In addition, non-recurring or discrete items, including interest on prior year tax liabilities, are recorded during the period in which they occur. To the extent that actual income or loss before taxes for the full year differs from the forecast estimates applied at the end of the most recent interim period, the actual tax rate recognized for the year ending December 31, 2013 could be materially different from the forecasted rate used for the three months ended March 31, 2013. We recognized a benefit for income taxes of $2.3 million for the three months ended March 31, 2013, an effective tax rate of 38.2%. The effective tax rate for the first quarter of 2013 exceeded U.S. federal statutory rate of 35% by the net of discrete benefits partially offset by state taxes and non-deductible permanent differences. During the first quarter of 2012, we recognized a provision for income taxes of $0.9 million, an effective tax rate of 39.1%. The effective tax rate for the first quarter of 2013 and 2012 exceeded the U.S. federal statutory rate of 35% due to state taxes, discrete items, and non-deductible permanent differences.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Net Earnings Per Share [Abstract]

Net Earnings Per Share

14. NET EARNINGS PER SHARE

Basic earnings per share is based on the weighted average number of common shares outstanding. Diluted earnings per share is based on the weighted average number of common shares outstanding, as well as dilutive potential common shares which, in the Company's case, comprise shares issuable under its equity compensation plans described in Note 9 of the consolidated financial statements. The treasury stock method is used to calculate dilutive shares, which reduces the gross number of dilutive shares by the number of shares purchasable from the proceeds of the options assumed to be exercised and the unrecognized expense related to the restricted stock and restricted stock unit awards assumed to have vested.

The following table sets forth the computation of basic and diluted loss (income) per share for the three months ended March 31 (in thousands):


		2013			2012
Numerator:
(Loss) income from continuing operations	$	(3,643	)	$	1,449
Loss from discontinued operations		(4	)		(87	)
Net (loss) income available to common shareholders	$	(3,647	)	$	1,362

Denominator for basic earnings per share:
Weighted average shares outstanding		30,877			30,718

Denominator for diluted earnings per share:
Weighted average shares outstanding		30,877			30,718
Common stock options and restricted stock		-			133
Weighted average shares and conversions		30,877			30,851

For the three months ended March 31, 2013, all stock options, unvested restricted stock, and unvested restricted stock units were anti-dilutive and, therefore, not included in the dilutive loss per share calculation. The number of weighted average stock options, unvested restricted stock, and unvested restricted stock units that were not included in the dilutive loss per share calculation because the effect would have been anti-dilutive was 181,925 shares for the three months ended March 31, 2013.
