Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	1. BASIS OF PRESENTATION In the opinion of Patrick Industries, Inc. (“Patrick” or the “Company”), the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly the Company’s financial position as of March 26, 2017 and December 31, 2016 , and its results of operations and cash flows for the three months ended March 26, 2017 and March 27, 2016 . Patrick’s unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission and in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to those rules or regulations. For a description of significant accounting policies used by the Company in the preparation of its consolidated financial statements, please refer to Note 2 of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 . The December 31, 2016 condensed consolidated statement of financial position data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. Operating results for the first quarter ended March 26, 2017 are not necessarily indicative of the results to be expected for the year ending December 31, 2017 . Certain amounts in the prior year’s condensed consolidated financial statements and notes have been reclassified to conform to the current year presentation. See Notes 2 and 8 for additional details. In preparation of Patrick’s condensed consolidated financial statements as of and for the first quarter ended March 26, 2017 , management evaluated all material subsequent events or transactions that occurred after the balance sheet date through the date of issuance of the Form 10-Q that required recognition or disclosure in the consolidated financial statements. See Note 15 for an event that occurred subsequent to the balance sheet date.

Accounting Policies [Abstract]
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS	2. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS Revenue Recognition In May 2014, the Financial Accounting Standards Board (“FASB”) issued a new accounting standard which specifies how and when to recognize revenue as well as providing informative, relevant disclosures. In August 2015, the FASB deferred the effective date of this standard by one year, which would become effective for fiscal years beginning after December 15, 2017. Based on an evaluation and review of its current accounting policies and practices related to the recognition of revenue, the Company does not anticipate that the adoption of this new accounting standard will have a material impact on the condensed consolidated statements of operations, financial position or cash flows. The Company expects to adopt this standard as of January 1, 2018, under the modified retrospective method where the cumulative effect is recognized at the date of initial application. Leases In February 2016, the FASB issued a new accounting standard that will require that an entity recognize lease assets and lease liabilities on its balance sheet for leases in excess of one year that were previously classified as operating leases under U.S. GAAP. The standard also requires companies to disclose in the footnotes to the financial statements information about the amount, timing, and uncertainty for the payments made for the lease agreements. The standard is effective for financial statements issued for annual and interim periods beginning after December 15, 2018 on a retroactive basis. Early adoption is permitted. The Company is currently evaluating the effect of adopting this new accounting standard and has not yet determined the impact that the implementation of it will have on its condensed consolidated financial statements. Stock Compensation In March 2016, the FASB issued a new accounting standard for share-based payments relating to: (i) the income tax consequences related to exercised or vested share-based payment awards; (ii) the classification of awards as assets or liabilities; and (iii) the classification in the condensed consolidated statements of cash flows. In addition, the standard provides an accounting policy election to account for forfeitures as they occur. This standard is effective for financial statements issued for annual and interim periods beginning after December 15, 2016 and early adoption is permitted. The Company elected to early adopt the requirements of this accounting standard in the fourth quarter of 2016 and retroactively reflected the impact of the adoption in its financial statements effective January 1, 2016 as required under the standard. Specifically, the excess tax benefits of $0.9 million related to the settlement of share-based compensation that were realized in the first quarter of 2016, and previously recorded in additional paid-in capital, were reclassified as a reduction to income tax expense on the condensed consolidated statement of income for the first quarter ended March 27, 2016. In addition, as required under the new standard, cash paid by directly withholding shares for tax withholding purposes of $0.6 million was reclassified from operating activities to financing activities in the condensed consolidated statement of cash flows for the three months ended March 27, 2016. Furthermore, the Company elected to change its accounting policy to account for forfeitures for share-based awards when they occur. Cash Flow Statement Classifications In August 2016, the FASB issued a new accounting standard related to the classification of certain cash receipts and cash payments in the statement of cash flows. This standard is effective for financial statements issued for annual and interim periods beginning after December 15, 2017. The standard may be applied on a retrospective basis and early adoption is permitted. The Company anticipates adopting the new standard as of January 1, 2018 as required and has determined that the implementation of it will have no impact on its condensed consolidated statements of cash flows for the periods presented. Goodwill Impairment In January 2017, the FASB issued a new accounting standard that simplifies the accounting for goodwill impairments by eliminating step two from the goodwill impairment test. The standard requires that the impairment loss be measured as the excess of the reporting unit's carrying amount over its fair value. It eliminates the second step that requires the impairment to be measured between the implied value of a reporting unit's goodwill and its carrying value. The standard is effective for annual and any interim impairment tests for periods beginning after December 15, 2019 and early adoption is permitted. The Company is currently evaluating the effect of adopting this new accounting standard and has not yet determined the impact that the implementation of it will have on its condensed consolidated financial statements. Definition of a Business In January 2017, the FASB issued a new accounting standard that clarifies the definition of a business. This standard will assist companies in interpreting the definition of a business which may affect certain areas of accounting including acquisitions, disposals, goodwill and consolidation. The standard is effective for financial statements issued for annual and interim periods beginning after December 15, 2017. The standard may be applied on a retrospective basis and early adoption is permitted. The Company is currently evaluating the effect of adopting this new accounting standard and has not yet determined the impact that the implementation of it will have on its condensed consolidated financial statements.

Debt Disclosure [Abstract]
DEFERRED FINANCING / DEBT ISSUANCE COSTS	3. DEFERRED FINANCING / DEBT ISSUANCE COSTS The condensed consolidated statements of financial position at March 26, 2017 and December 31, 2016 reflect the reclassification of assets related to deferred financing costs associated with the Term Loan (as defined herein) outstanding under the Company’s 2015 Credit Facility (as defined herein) that were reclassified and netted against long-term debt outstanding. The reclassification is the result of the Company’s adoption of new accounting guidance that requires debt issuance costs be presented in the statement of financial position as a reduction in the carrying amount of debt, consistent with the presentation of debt issuance discounts. The deferred financing costs related to the 2015 Revolver (as defined herein) were not reclassified to long-term debt and are reflected as a component of non-current assets on the condensed consolidated statements of financial position for the periods presented because the guidance does not apply to line-of-credit arrangements. In the first quarter of 2016, the Company adopted this guidance as required on a retrospective basis. At December 31, 2016, the total maximum borrowing limit under the Company’s 2015 Credit Facility was $360.0 million , of which $90.6 million or 25% represented the total commitment under the Term Loan and was the basis for allocating a portion of the deferred financing costs to the Term Loan. At March 26, 2017 the total maximum borrowing limit under the Company's 2015 Credit Facility was $450.0 million , of which $ 82.7 million or 18% represented the total commitment under the Term Loan and was the basis for allocating a portion of the deferred financing costs to the Term Loan. Unamortized total deferred financing costs were $3.1 million and $2.3 million at March 26, 2017 and December 31, 2016 , respectively. The following tables illustrate the effect of the change on certain line items within the condensed consolidated statements of financial position for the periods presented.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND INTANGIBLE ASSETS	5. GOODWILL AND INTANGIBLE ASSETS The Company acquired intangible assets in various acquisitions in 2016 and through the first quarter of 2017 that were determined to be business combinations. The goodwill recognized is expected to be deductible for income tax purposes for each of the 2017 and 2016 acquisitions with the exception of the acquisition of BH Electronics, Inc. See Note 6 for further details. Goodwill and other intangible assets are allocated to the Company’s reporting units at the date they are initially recorded. Goodwill and indefinite-lived intangible assets are not amortized but are subject to an impairment test based on their estimated fair value performed annually in the fourth quarter (or under certain circumstances more frequently as warranted). Goodwill impairment testing is performed at the reporting unit level, one level below the business segment . Finite-lived intangible assets that meet certain criteria continue to be amortized over their useful lives and are also subject to an impairment test based on estimated undiscounted cash flows when impairment indicators exist. The Company assesses finite-lived intangible assets for impairment if events or changes in circumstances indicate that the carrying value may exceed the fair value. No impairment was recognized during the first quarter ended March 26, 2017 and March 27, 2016 related to goodwill, indefinite-lived intangible assets or finite-lived intangible assets. There have been no material changes to the method of evaluating impairment related to goodwill, indefinite-lived intangible assets or finite-lived intangible assets during the first quarter of 2017. Goodwill Changes in the carrying amount of goodwill for the first quarter ended March 26, 2017 by segment are as follows: (thousands) Manufacturing Distribution Total Balance - December 31, 2016 $ 100,592 $ 9,301 $ 109,893 Acquisitions 1,750 — 1,750 Adjustment to prior year purchase price allocations (1,443 ) — (1,443 ) Balance - March 26, 2017 $ 100,899 $ 9,301 $ 110,200 Other Intangible Assets Other intangible assets are comprised of customer relationships, non-compete agreements and trademarks. Customer relationships and non-compete agreements represent finite-lived intangible assets that have been recorded in the Manufacturing and Distribution segments along with related amortization expense. As of March 26, 2017 , the other intangible assets balance of $164.2 million is comprised of $42.7 million of trademarks which have an indefinite life, and therefore, no amortization expense has been recorded, and $121.5 million pertaining to customer relationships and non-compete agreements which are being amortized over periods ranging from two to 19 years. For the finite-lived intangible assets attributable to the 2017 acquisition of Medallion Plastics, Inc., the useful life pertaining to non-compete agreements and to customer relationships for this acquisition was three years and 10 years, respectively. Amortization expense for the Company’s intangible assets in the aggregate was $4.2 million and $2.8 million for the first quarter ended March 26, 2017 and March 27, 2016 , respectively.

Business Combinations [Abstract]
ACQUISITIONS	6. ACQUISITIONS General The Company completed one acquisition in the first quarter of 2017 and eight acquisitions in 2016 , including two in the first quarter of 2016. Each of the acquisitions was funded through borrowings under the Company’s credit facility in existence at the time of acquisition. Assets acquired and liabilities assumed in the individual acquisitions were recorded on the Company’s condensed consolidated statements of financial position at their estimated fair values as of the respective dates of acquisition. In general, the acquisitions described below provided the opportunity for the Company to either establish a new presence in a particular market and/or expand its product offerings in an existing market and increase its market share and per unit content. For each acquisition, the excess of the purchase consideration over the fair value of the net assets acquired was recorded as goodwill, which represents the value of leveraging the Company’s existing purchasing, manufacturing, sales, and systems resources with the organizational talent and expertise of the acquired companies’ respective management teams to maximize efficiencies, revenue impact, market share growth, and net income. The goodwill recognized is expected to be deductible for income tax purposes for the 2017 acquisition and for each of the 2016 acquisitions with the exception of the BH Electronics, Inc. acquisition. Intangible asset values were estimated using income based valuation methodologies. See Note 5 for information regarding the amortization periods assigned to finite-lived intangible assets. For the first quarter ended March 26, 2017 , revenue of approximately $0.3 million was included in the Company’s condensed consolidated statements of income relating to the business acquired in the first quarter of 2017 .

Earnings Per Share [Abstract]
NET INCOME PER COMMON SHARE	8. NET INCOME PER COMMON SHARE Basic net income per common share is computed by dividing net income by the weighted-average number of common shares outstanding. Diluted net income per common share is computed by dividing net income by the weighted-average number of common shares outstanding, plus the dilutive effect of stock options, stock appreciation rights, and restricted stock units (collectively “Common Stock Equivalents”). The dilutive effect of Common Stock Equivalents is calculated under the treasury stock method using the average market price for the period. Certain Common Stock Equivalents were not included in the computation of diluted net income per common share because the exercise prices of those Common Stock Equivalents were greater than the average market price of the common shares. Income per common share is calculated for the first quarter as follows: First Quarter Ended (thousands except per share data) Mar. 26, 2017 Mar. 27, 2016 Net income for basic and diluted per share calculation $ 17,467 $ 12,975 Weighted average common shares outstanding - basic 15,238 14,948 Effect of potentially dilutive securities 311 244 Weighted average common shares outstanding - diluted 15,549 15,192 Basic net income per common share $ 1.15 $ 0.87 Diluted net income per common share $ 1.12 $ 0.85 On March 14, 2017, the Company completed a public offering of 1,350,000 shares of its common stock at a price of $73.00 per share for total proceeds of $98.6 million less related costs.

The 2015 Credit Agreement includes certain definitions, terms and reporting requirements and includes the following additional provisions: • The initial maturity date for the 2015 Credit Facility was April 28, 2020. Pursuant to the third amendment. the maturity date was extended to March 17, 2022; • The initial Term Loan had repayment installments of approximately $2.7 million per quarter with the remaining balance due at maturity. Following the expansion of the Term Loan in July 2016 pursuant to the second amendment, the quarterly repayment installments were increased to approximately $3.9 million beginning on September 30, 2016 with the remaining balance due at maturity. There was no impact to the quarterly repayment installments as a result of the third amendment. • The interest rates for borrowings under the 2015 Revolver and the Term Loan are the Base Rate plus the Applicable Margin or LIBOR plus the Applicable Margin, with a fee payable by the Company on unused but committed portions of the 2015 Revolver; • The 2015 Revolver includes a sub-limit up to $10.0 million for same day advances (“Swing Line”) which shall bear interest based upon the Base Rate plus the Applicable Margin; • Up to $10.0 million of the 2015 Revolver will be available as a sub facility for the issuance of standby letters of credit, which are subject to certain expiration dates; • The financial covenants include requirements as to a consolidated total leverage ratio and a consolidated fixed charge coverage ratio, and other covenants include limitations and restrictions concerning permitted acquisitions, investments, sales of assets, liens on assets, dividends and other payments; and • Customary prepayment provisions, representations, warranties and covenants, and events of default.

At December 31, 2016 , the Company had $82.7 million outstanding under the Term Loan under the LIBOR-based option, and borrowings outstanding under the 2015 Revolver of (i) $187.0 million under the LIBOR-based option and (ii) $3.4 million under the Prime Rate-based option. The interest rate for borrowings at December 31, 2016 was the Prime Rate plus 0.75% (or 4.50% ), or LIBOR plus 1.75% (or 2.5625% ). The fee payable on committed but unused portions of the 2015 Revolver was 0.225% at March 26, 2017 and December 31, 2016. Pursuant to the 2015 Credit Agreement, the financial covenants include: (a) a required maximum consolidated total leverage ratio, measured on a quarter-end basis, not to exceed 3.00 : 1.00 for the 12 -month period ending on such quarter-end; and (b) a required minimum consolidated fixed charge coverage ratio, measured on a quarter-end basis, of at least 1.50 : 1.00 for the 12 -month period ending on such quarter-end. The consolidated total leverage ratio is the ratio for any period of consolidated total indebtedness (as measured as of the second day following the end of the immediately preceding fiscal quarter) to consolidated adjusted earnings before interest, taxes, depreciation and amortization (“EBITDA”). Consolidated total indebtedness for any period is the sum of: (i) total debt outstanding under the 2015 Revolver and the Term Loan; (ii) capital leases and letters of credit outstanding; and (iii) deferred payment obligations. The consolidated fixed charge coverage ratio for any period is the ratio of consolidated EBITDA less restricted payments, taxes paid and capital expenditures as defined under the 2015 Credit Agreement to consolidated fixed charges. Consolidated fixed charges for any period is the sum of interest expense and scheduled principal payments on outstanding indebtedness under the Term Loan. As of and for the March 26, 2017 reporting date, the Company was in compliance with both of these financial debt covenants as required under the terms of the 2015 Credit Agreement. The required maximum consolidated total leverage ratio and the required minimum consolidated fixed charge coverage ratio compared to the actual amounts as of March 26, 2017 and for the fiscal period then ended are as follows: Required Actual Consolidated total leverage ratio (12-month period) 3.00 1.31 Consolidated fixed charge coverage ratio (12-month period) 1.50 4.04 Interest paid for the first quarter of 2017 was $1.7 million .

SUBSEQUENT EVENT	SUBSEQUENT EVENT Acquisition In May 2017, the Company acquired 100% of the membership interests of Leisure Product Enterprises, LLC (“LPE”) for a net purchase price of approximately $73.5 million . LPE is comprised of three complementary manufacturing companies primarily serving the marine and industrial markets: Marine Electrical Products, located in Lebanon, Missouri, supplies marine OEMs with fully-assembled boat dash and helm assemblies, including electrical wiring harnesses as well as custom parts and assemblies for the industrial, commercial, and off-road vehicle markets; Florida Marine Tanks, located in Henderson, North Carolina, supplies aluminum fuel and holding tanks for marine and industrial customers; and Marine Concepts/Design Concepts, with facilities located in Sarasota, Florida and Cape Coral, Florida, designs, engineers and manufactures CNC plugs, open and closed composite molds, and CNC molds for fiberglass boat manufacturers. The acquisition of LPE provides the opportunity for the Company to further expand its product offerings in the marine market and increase its market share and per unit content. The acquisition was funded under the Company's 2015 Credit Facility. The Company is in the process of allocating the purchase consideration to the fair value of the assets acquired and expects to provide a summary of each in its report on Form 10-Q for the second quarter ending June 25, 2017. The results of operations will be included in the Company's condensed consolidated financial statements from the date of acquisition and in the Manufacturing segment.

RECENTLY ISSUED ACCOUNTING PR20

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS (Policies)	3 Months Ended
	Mar. 26, 2017
Accounting Policies [Abstract]
Recent issued accounting pronouncements	Revenue Recognition In May 2014, the Financial Accounting Standards Board (“FASB”) issued a new accounting standard which specifies how and when to recognize revenue as well as providing informative, relevant disclosures. In August 2015, the FASB deferred the effective date of this standard by one year, which would become effective for fiscal years beginning after December 15, 2017. Based on an evaluation and review of its current accounting policies and practices related to the recognition of revenue, the Company does not anticipate that the adoption of this new accounting standard will have a material impact on the condensed consolidated statements of operations, financial position or cash flows. The Company expects to adopt this standard as of January 1, 2018, under the modified retrospective method where the cumulative effect is recognized at the date of initial application. Leases In February 2016, the FASB issued a new accounting standard that will require that an entity recognize lease assets and lease liabilities on its balance sheet for leases in excess of one year that were previously classified as operating leases under U.S. GAAP. The standard also requires companies to disclose in the footnotes to the financial statements information about the amount, timing, and uncertainty for the payments made for the lease agreements. The standard is effective for financial statements issued for annual and interim periods beginning after December 15, 2018 on a retroactive basis. Early adoption is permitted. The Company is currently evaluating the effect of adopting this new accounting standard and has not yet determined the impact that the implementation of it will have on its condensed consolidated financial statements. Stock Compensation In March 2016, the FASB issued a new accounting standard for share-based payments relating to: (i) the income tax consequences related to exercised or vested share-based payment awards; (ii) the classification of awards as assets or liabilities; and (iii) the classification in the condensed consolidated statements of cash flows. In addition, the standard provides an accounting policy election to account for forfeitures as they occur. This standard is effective for financial statements issued for annual and interim periods beginning after December 15, 2016 and early adoption is permitted. The Company elected to early adopt the requirements of this accounting standard in the fourth quarter of 2016 and retroactively reflected the impact of the adoption in its financial statements effective January 1, 2016 as required under the standard. Specifically, the excess tax benefits of $0.9 million related to the settlement of share-based compensation that were realized in the first quarter of 2016, and previously recorded in additional paid-in capital, were reclassified as a reduction to income tax expense on the condensed consolidated statement of income for the first quarter ended March 27, 2016. In addition, as required under the new standard, cash paid by directly withholding shares for tax withholding purposes of $0.6 million was reclassified from operating activities to financing activities in the condensed consolidated statement of cash flows for the three months ended March 27, 2016. Furthermore, the Company elected to change its accounting policy to account for forfeitures for share-based awards when they occur. Cash Flow Statement Classifications In August 2016, the FASB issued a new accounting standard related to the classification of certain cash receipts and cash payments in the statement of cash flows. This standard is effective for financial statements issued for annual and interim periods beginning after December 15, 2017. The standard may be applied on a retrospective basis and early adoption is permitted. The Company anticipates adopting the new standard as of January 1, 2018 as required and has determined that the implementation of it will have no impact on its condensed consolidated statements of cash flows for the periods presented. Goodwill Impairment In January 2017, the FASB issued a new accounting standard that simplifies the accounting for goodwill impairments by eliminating step two from the goodwill impairment test. The standard requires that the impairment loss be measured as the excess of the reporting unit's carrying amount over its fair value. It eliminates the second step that requires the impairment to be measured between the implied value of a reporting unit's goodwill and its carrying value. The standard is effective for annual and any interim impairment tests for periods beginning after December 15, 2019 and early adoption is permitted. The Company is currently evaluating the effect of adopting this new accounting standard and has not yet determined the impact that the implementation of it will have on its condensed consolidated financial statements. Definition of a Business In January 2017, the FASB issued a new accounting standard that clarifies the definition of a business. This standard will assist companies in interpreting the definition of a business which may affect certain areas of accounting including acquisitions, disposals, goodwill and consolidation. The standard is effective for financial statements issued for annual and interim periods beginning after December 15, 2017. The standard may be applied on a retrospective basis and early adoption is permitted. The Company is currently evaluating the effect of adopting this new accounting standard and has not yet determined the impact that the implementation of it will have on its condensed consolidated financial statements.
