Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidated Financial Statements	CONSOLIDATED FINANCIAL STATEMENTS The accompanying consolidated financial statements have been prepared by Gibraltar Industries, Inc. (the Company) without audit. In the opinion of management, all adjustments (consisting of normal recurring adjustments and accruals) necessary to present fairly the results of operations and other comprehensive income for the three months ended March 31, 2016 and 2015 , the financial position at March 31, 2016 and December 31, 2015 , the statements of cash flow for the three months ended March 31, 2016 and 2015 , and the statement of shareholders’ equity for the three months ended March 31, 2016 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, 2015 as filed on Form 10-K along with any new disclosures provided below. The consolidated balance sheet at December 31, 2015 has been derived from the audited consolidated financial statements at that date, 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 periods ended March 31, 2016 are not necessarily indicative of the results to be expected for the full year. The Company is subject to reduced activity in the first and fourth quarters as colder, inclement weather reduces order rates from end markets it serves.

Recent Accounting Pronouncements (Notes)	Mar. 31, 2016
Accounting Policies [Abstract]
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, "Revenue from Contracts with Customers (Topic 606)." The update clarifies the principles for recognizing revenue and develops a common standard for U.S. Generally Accepted Accounting Principles and International Financial Reporting Standards. More specifically, the core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU 2015-14 which deferred the effective date of Topic 606 to annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. In March 2016, the FASB issued ASU 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net).” ASU 2016-08 clarifies the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing.” ASU 2016-10 clarifies the implementation guidance on identifying performance obligations. These ASUs apply to all companies that enter into contracts with customers to transfer goods or services. These ASUs are effective for public entities for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted, but not before interim and annual reporting periods beginning after December 15, 2016. Entities have the choice to apply these ASUs either retrospectively to each reporting period presented or by recognizing the cumulative effect of applying these standards at the date of initial application and not adjusting comparative information. We are currently evaluating the requirements of these standards and have not yet determined the impact on our consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, "Inventory (Topic 330)." The amendments to this Update were issued to change the measurement of inventory to the lower of cost and net realizable value. The guidance, which is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years, may be applied prospectively and early adopted for the beginning of an interim or annual period. The Company is currently evaluating the impact of adopting the new standard which is not expected to have a material impact on the our Balance Sheet or Statements of Operations. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 requires lessees to recognize a lease liability and a right-of-use asset on the balance sheet. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the requirements of ASU 2016-02 and have not yet determined its impact on our consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, "Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting." ASU 2016-09 simplifies the accounting for share-based payment award transactions including: income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the requirements of ASU 2016-09 and have not yet determined its impact on our consolidated financial statements.

Business Combinations [Abstract]
Acquisitions	ACQUISITIONS On June 9, 2015, the Company acquired all of the outstanding stock of Rough Brothers Manufacturing, Inc., RBI Solar, Inc., and affiliates, collectively known as "RBI". RBI has established itself during the past six years among North America's fastest-growing providers of racking and mounting systems for solar energy installations and is among the largest commercial greenhouse manufacturers in North America. RBI is a full service provider that engineers, manufactures and installs racking systems for solar power developers, contractors and companies. In addition, RBI designs, manufactures and erects greenhouses for commercial, institutional and retail customers. The acquisition of RBI is expected to enable the Company to leverage its expertise in structural metals manufacturing, materials sourcing and logistics to help meet the fast-growing global demand for solar racking solutions. The results of RBI have been included in the Company’s consolidated financial results since the date of acquisition (within the Company's Renewable Energy and Conservation segment). The final aggregate purchase consideration for the acquisition of RBI was $147,585,000 , which includes a working capital adjustment and certain other adjustments provided for in the stock purchase agreement. The final purchase adjustment of $2,314,000 that was accrued as of December 31, 2015, was paid by the Company during the first quarter of 2016. The purchase price for the acquisition was allocated to the assets acquired and liabilities assumed based upon their respective fair values. The excess consideration of $57,180,000 , was recorded as goodwill of which $37,969,000 is deductible for tax purposes. Goodwill represents future economic benefits arising from other assets acquired that could not be individually identified including workforce additions, growth opportunities, and increased presence in the renewable energy markets. The allocation of the purchase consideration to the fair value of the assets acquired and liabilities assumed is as follows as of the date of the acquisition (in thousands): Cash $ 4,651 Working capital 21,436 Property, plant, and equipment 12,797 Acquired intangible assets 56,392 Other assets 3,049 Deferred income taxes (4,892 ) Other liabilities (3,028 ) Goodwill 57,180 Fair value of purchase consideration $ 147,585 The Company recorded an indemnification asset and liability of $3.0 million on the opening balance sheet related to the seller’s obligation to fully indemnify the Company for the outcome of potential contingent liabilities related to uncertainty of income tax positions in foreign jurisdictions. The liability and related indemnification asset may or may not be realized, and any unrealized liability is scheduled to expire in 2018. The intangible assets acquired in this acquisition consisted of the following (in thousands): Fair Value Estimated Trademarks $ 13,550 Indefinite Technology 3,550 7-15 years Customer relationships 32,892 11-17 years Non-compete agreements 1,300 5 years Backlog 5,100 0.5 years Total $ 56,392 The acquisition was financed through cash on hand and borrowings under the Company's revolving credit facility. The Company incurred certain acquisition-related costs composed of legal and consulting fees, and these costs were recognized as a component of selling, general and administrative expenses in the consolidated statement of operations. The Company also recognized acquisition-related costs for the sale of inventory at fair value which was a portion of the purchase price allocation of this acquisition. The following unaudited pro forma financial information presents the combined results of continuing operations as if the acquisition of RBI had occurred as of January 1, 2015. The pro forma information includes certain adjustments, including depreciation and amortization expense, interest expense and certain other adjustments, together with related income tax effects. The pro forma amounts may not be indicative of the results that actually would have been achieved had the acquisition occurred as of January 1, 2015 and are not necessarily indicative of future results of the combined companies (in thousands, except per share data): Three Months Ended 2015 Net sales $ 240,538 Net income $ 7,582 Net income per share - Basic $ 0.24 Net income per share - Diluted $ 0.24 Note: The above pro forma financial information should be read in conjunction with the Exit Activity Costs and Asset Impairments footnote.

Derivatives	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES The Company is exposed to certain risks arising from both its business operations and economic conditions. The primary risks that the Company manages through its derivative instruments from time to time are foreign currency exchange rate risk and commodity pricing risk. We enter into derivative financial instruments with various financial institutions to minimize counterparty credit risk. Depending on the type of transaction, we may enter into either derivatives that are designated as hedging instruments and/or derivatives that are not designated as hedging instruments. As of March 31, 2016 , we do not currently hold any derivatives classified as hedging instruments and qualifying for hedge accounting. Derivatives not designated as hedging instruments To minimize foreign currency exposure, the Company had foreign currency forwards with notional amounts of $1,455,000 at March 31, 2016 . These derivative instruments mature in April 2016. No foreign currency or commodity options were outstanding at March 31, 2016 Commodity options, foreign exchange forwards and forward exchange options are recorded in the consolidated balance sheet at fair value and the resulting gains or losses are recorded to other income in the consolidated statement of operations.

Fair Value Measurements	Mar. 31, 2016
Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, various techniques and assumptions can be used to estimate 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 follows: • Level 1 - Unadjusted quoted prices in active markets that are accessible to the reporting entity at the measurement date for identical assets and 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 - Unobservable inputs for the assets or liability supported by little or no market activity. Level 3 inputs are based on the Company’s assumptions used to measure assets and liabilities at fair value. The Company's derivatives are valued using various pricing models or discounted cash flow analyses that incorporate observable market data, such as interest rate yield curves, currency rates and implied volatility. In addition, the Company received fair value estimates from contract counterparties to verify the reasonableness of the Company's estimates. These derivatives are classified as Level 2 within the valuation hierarchy. The following table presents the fair values and classification of our financial assets (liabilities) measured on a recurring basis, all of which are classified as Level 2 (in thousands): Classification March 31, 2016 December 31, 2015 Foreign currency exchange options Other current assets — 1,792 Foreign currency exchange forwards Other current liabilities 85 14 The Company’s only other financial instrument for which the carrying value differs from its fair value is long-term debt. At March 31, 2016 and December 31, 2015 , the fair value of outstanding debt net of unamortized debt issuance costs was $213,632,000 and $214,007,000 , respectively, compared to its carrying value of $209,432,000 and $209,282,000 , respectively. The fair value of the Company’s Senior Subordinated 6.25% Notes is classified as Level 1 within the fair value hierarchy and was estimated based on quoted market prices.

Restructuring and Related Activities [Abstract]
Exit Activity Costs And Asset Impairments	EXIT ACTIVITY COSTS AND ASSET IMPAIRMENTS The Company’s business strategy has been formulated to effect a transformation of its operations and much-improved financial results over a five year period. In 2015, the first year of this planned transformation, an 80/20 simplification initiative commenced across many of our business units. This on-going initiative, in part, focuses the Company’s internal resources on further increasing the value provided to our customers. A result of this initiative was the identification of low-volume, internally-produced products which have been or will be outsourced or discontinued. During the three months ended March 31, 2016 , there were charges resulting from this identification that aggregated $910,000 . These charges relate to the write-down of inventory and impairment of machinery and equipment associated with either discontinued product lines or the reduction of manufactured goods offered within a product line. These assets were written down to their sale or scrap value, and were subsequently sold or disposed of. Exit activity costs of $788,000 were also incurred during the three months ended March 31, 2016 relating to contract termination costs, severance costs, and other moving and closing costs. These costs were the result of the closing and consolidation of facilities, relocation of inventory and equipment at those facilities and the reduction of workforce associated with the discontinued products and closed facilities. During the three months ended March 31, 2015 , the Company sold one facility and eliminated one product line which resulted in asset impairment charges of $108,000 and exit activity costs of $111,000 . In addition, the Company sold and leased back a facility, which resulted in a gain of $6,799,000 . The following table sets forth the asset impairment charges, exit activity costs and gain on facilities sold in conjunction with these efforts, incurred by segment during the three months ended March 31, related to the restructuring activities described above (in thousands): 2016 2015 Inventory write-downs &/or asset impairment charges Exit activity costs Total Inventory write-downs &/or asset impairment charges Exit activity costs Gain on sale leaseback Total Residential Products $ 688 $ 330 $ 1,018 $ 108 $ 111 $ (6,799 ) $ (6,580 ) Industrial & Infrastructure Products 222 458 680 — — — — Total exit activity costs & asset impairments $ 910 $ 788 $ 1,698 $ 108 $ 111 $ (6,799 ) $ (6,580 ) The following table provides a summary of where the asset impairments and exit activity costs (gains) were recorded in the statement of operations for the three months ended March 31, (in thousands): Three Months Ended 2016 2015 Cost of sales $ 1,118 $ 188 Selling, general, and administrative expense 580 (6,768 ) Net asset impairment and exit activity charges (gains) $ 1,698 $ (6,580 ) The following table reconciles the beginning and ending liability for exit activity costs relating to the Company’s facility consolidation efforts (in thousands): 2016 2015 Balance at January 1 $ 603 $ 575 Exit activity costs recognized 788 111 Cash payments (430 ) (323 ) Balance at March 31 $ 961 $ 363

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, 2016 could be materially different from the forecasted rate used for the three months ended March 31, 2016 . The effective tax rate for the three months ended March 31, 2016 exceeded the U.S. federal statutory rate of 35% due to state taxes partially offset by deductible permanent differences and favorable discrete items. The effective tax rate for the three months ended March 31, 2015 exceeded the U.S. federal statutory rate of 35% due to state taxes partially offset by deductible permanent differences.

Accounting Policies [Abstract]
Recent Accounting Pronouncements	In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, "Revenue from Contracts with Customers (Topic 606)." The update clarifies the principles for recognizing revenue and develops a common standard for U.S. Generally Accepted Accounting Principles and International Financial Reporting Standards. More specifically, the core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU 2015-14 which deferred the effective date of Topic 606 to annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. In March 2016, the FASB issued ASU 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net).” ASU 2016-08 clarifies the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing.” ASU 2016-10 clarifies the implementation guidance on identifying performance obligations. These ASUs apply to all companies that enter into contracts with customers to transfer goods or services. These ASUs are effective for public entities for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted, but not before interim and annual reporting periods beginning after December 15, 2016. Entities have the choice to apply these ASUs either retrospectively to each reporting period presented or by recognizing the cumulative effect of applying these standards at the date of initial application and not adjusting comparative information. We are currently evaluating the requirements of these standards and have not yet determined the impact on our consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, "Inventory (Topic 330)." The amendments to this Update were issued to change the measurement of inventory to the lower of cost and net realizable value. The guidance, which is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years, may be applied prospectively and early adopted for the beginning of an interim or annual period. The Company is currently evaluating the impact of adopting the new standard which is not expected to have a material impact on the our Balance Sheet or Statements of Operations. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 requires lessees to recognize a lease liability and a right-of-use asset on the balance sheet. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the requirements of ASU 2016-02 and have not yet determined its impact on our consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, "Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting." ASU 2016-09 simplifies the accounting for share-based payment award transactions including: income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the requirements of ASU 2016-09 and have not yet determined its impact on our consolidated financial statements.
