Do you need a permit to replace a roof in Woodbury, MN?

Roofing questions: Woodbury, MN

Do you need a permit to replace a roof in Woodbury, MN?

Yes, a permit is required to replace a roof in Woodbury, MN. NO SIZE OR VALUE THRESHOLD EXEMPTS ROOFING. Woodbury City Code Sec. 6-19(g), read in full, exempts minor one- and two-family alterations from a permit only when the work meets ALL of six conditions, including "(5) Does not include removal or replacement of roofing" and "(6) And the value is less than $3,000.00." Because condition (5) requires the work to exclude roofing altogether, the $3,000 value threshold never operates to exempt a reroofing project -- a permit is required for reroofing at any value or size. Minnesota Rules part 1300.0120, subpart 4 (the statewide work-exempt-from-permit list, read in full) contains no roofing item either.

Is ice & water shield required in Woodbury, MN?

Yes. STATE-GOVERNED, NOT CITY-SET -- applies identically in Woodbury as everywhere else in Minnesota, because Woodbury adopts the Minnesota State Building Code without local amendment on this point (see adopted_code). Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) to pre-fill "ICE BARRIER UNDERLAYMENT REQUIRED[h] ... Yes" for the entire state; footnote h cross-references IRC Sections R905.1.2, R905.2.7, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1 and R905.8.3.1 for the applicable ice-barrier standard. Woodbury has no authority to opt out of this (Minn. Stat. § 326B.121, subd. 2(c)). Woodbury's own Roofing Information Handout independently corroborates an ice-dam rule locally: "Ice dam protection is required on all roofs and shall extend from the edge of the roof 24" past the exterior wall line." GARAGE NUANCE: because the state table entry is a uniform pre-fill, no Woodbury-specific garage exemption has been on record; confirm garage-specific applicability with Building Inspections before relying on any blanket exemption.

Is drip edge required in Woodbury, MN?

No. STATE-GOVERNED, NOT CITY-SET -- applies identically in Woodbury as everywhere else in Minnesota, because Woodbury adopts the Minnesota State Building Code without local amendment on this point (see adopted_code). Minnesota Rules part 1309.0905, subpart 2 states in full: "IRC section R905.2.8.5. Section R905.2.8.5 is deleted in its entirety" -- the base IRC drip-edge provision has no force anywhere in Minnesota, including Woodbury. Woodbury has no authority to reinstate a drip-edge requirement beyond this state baseline (Minn. Stat. § 326B.121, subd. 2(c)).

Can you roof over an existing roof in Woodbury, MN?

STATE-GOVERNED, NOT CITY-SET; NO LOCAL OR STATE LAYER-LIMIT AMENDMENT FOUND. Minnesota Rules chapter 1309's own table of parts, read in full, lists only two parts amending IRC Chapter 9 (Roof Assemblies): part 1309.0903 (Section R903, Weather Protection -- kick-out flashing) and part 1309.0905 (Section R905, Requirements for Roof Coverings -- sheathing and drip edge, above). No part numbered 1309.0908 exists, meaning base IRC Section R908 (Roof Replacement) is not amended anywhere in the Minnesota Residential Code. Woodbury's own Chapter 6, Article II (Sec. 6-16 through 6-19, read in full, see adopted_code) makes no independent roof-layer amendment either -- it only adopts the state building code, two unrelated optional state chapters, and sets administrative fees. Because Woodbury has no authority to set a different layer limit than the state code provides (Minn. Stat. § 326B.121, subd. 2(c)), and because nobody on this project has read a Minnesota-specific numeric layer limit, no number is published here; base IRC Section R908 (as incorporated, unamended) applies in Woodbury as a pointer only. Base-code rule, read at 2018 IRC Section R908.3.1.1 (Roof recover not allowed) and quoted here rather than left behind the ICC paywall: a roof recover "shall not be permitted" where "the existing roof has two or more applications of any type of roof covering" (nor where the existing covering is water soaked or deteriorated, or is slate, clay, cement or asbestos-cement tile). One existing layer may therefore be recovered; a second existing layer forces tear-off to the deck.

Do roofing contractors need a license or registration in Woodbury, MN?

Yes. Minnesota has a statewide mandatory Residential Roofer (RR) license, per Minn. Stat. § 326B.805, subdivision 1, read in full: "A person who meets the definition of a residential roofer as defined in section 326B.802, subdivision 14, must be licensed by the commissioner as a residential roofer, residential building contractor, or residential remodeler." Administered by MN DLI, not the City of Woodbury. Woodbury's own City Code Sec. 6-96, read in full, independently requires the same thing locally: "No person shall engage in the work of a residential building contractor, remodeler, or specialty contractor for compensation in the city without a valid license issued by the state," and the city council may add a license-verification surcharge of up to $5.00 on permits requiring a licensed contractor. Woodbury's Roof, Siding & Windows page also warns that MN licensed roofers who are not lead-certified must complete a Lead Supplement Form for pre-1978 dwellings.

What building code does Woodbury, MN use?

STATE-GOVERNED, NOT CITY-SET. Woodbury City Code Sec. 6-17(a), read in full, states: "The Minnesota State Building Code, as adopted by the commissioner of administration pursuant to Minn. Stats. Chs. 16B.59 to 16B.75, including all of the amendments, rules and regulations established, adopted and published from time to time by the Minnesota Commissioner of Administration, through the Building Codes and Standards Division is hereby adopted by reference." Sec. 6-17(b) additionally adopts, locally, two OPTIONAL state chapters: "1. Chapter 1335, Floodproofing Regulations. 2. Chapter 1306, Special Fire Protection Systems; Subpart 3 New Buildings" -- neither of which touches roof assemblies. Woodbury's own ordinance names no independently-chosen code edition; it adopts whatever edition of the Minnesota State Building Code is currently in force. That code is Minn. Rules ch. 1309, the "Minnesota Residential Code," which under Minn. R. 1309.0010, subpart 1 incorporates by reference the 2018 IRC "except as qualified by the applicable provisions in Minnesota Rules, chapter 1300, and as amended in this chapter." Under Minn. Stat. § 326B.121, subd. 1(a)-(b), the State Building Code "is the standard that applies statewide" and "supersedes the building code of any municipality," and subd. 2(c) bars a municipality from requiring building code provisions "different from any provision of the State Building Code."
