Do I need a permit for roof replacement in
Romulus, MI?

Romulus roof replacement permits — the key details

Michigan Building Code R907 (reroofing) is the primary rule. Romulus enforces this strictly: any roof replacement requires a permit UNLESS the work is repair-only and covers less than 25% of roof area. A 'tear-off-and-replace' triggers a permit even if only the south-facing slope is done. If you have three or more existing layers of shingles, Michigan Code R907.4 mandates complete tear-off down to the deck — overlay is forbidden. The City of Romulus Building Department will reject any permit application that proposes overlay on a three-layer roof, and inspectors will cite the existing layers during the framing inspection. This rule exists because multiple layers trap heat and moisture, shortening roof life and increasing fire risk. Many Romulus homeowners discovered this rule mid-project and had to halt work, incurring crew delay charges.

Ice-and-water shield is a surprise sticking point in Romulus due to climate zone split. IRC R905.1.1 requires self-adhering membrane (ice-and-water shield) at eaves in all Michigan climate zones, but Romulus's north-of-Huron addresses (Zone 6A) must extend it 24 inches up the slope from the eave. South-of-Huron addresses (Zone 5A) require it at eaves and valleys only. Your permit application must specify which zone your address falls into and show shield placement on the submitted drawings or material list. If you don't specify, the permit will be held for clarification, adding 3-5 days. The City of Romulus Building Department references the Michigan Energy Code (which adopts the ICC model) for this requirement, and their inspectors have marked down jobs for undersized shield. Confirm your address zone with the City before submitting; they can tell you over the phone in 2 minutes.

Material changes and structural upgrades trigger full plan review. If you are changing from asphalt shingles to metal or concrete tile, you must submit a structural evaluation showing that the roof deck and framing can support the added load. Metal is roughly the same weight as asphalt, so it often passes; tile (15+ psf) usually requires reinforcement, adding $1,500–$5,000 to the project and 2-3 weeks of permit review. Romulus does not have a streamlined tile-permit path like some Florida cities; your application goes to the full review queue. Additionally, if your roof deck shows rot, soft spots, or missing sheathing, the permit includes a structural repair scope, which requires signed engineer drawings for spans over 16 inches. Many homeowners skip the structural step and get cited during framing inspection, forcing a halt and re-submission.

Underlayment specification and fastening pattern must be explicitly listed on the permit. Romulus inspectors will ask to see the roofing material specification sheet (brand, shingle class, fastening method: 4 nails per shingle vs. 6, etc.) before stamping approval. If you list a shingle brand but don't specify the fastening, the permit will be on hold pending clarification. The City prefers a simple one-page material summary; you don't need full architectural drawings for a residential roof, but you do need the vendor's spec. This is a common rejection point because homeowners or contractors submit a permit saying 'GAF Timberline shingles, Ice & Water Shield' and nothing else — not enough. Bring a spec sheet or email it to the City of Romulus Building Department before applying to avoid the back-and-forth.

The permit process in Romulus is slower than online-portal cities because there is no digital submission. You must visit City Hall (123 W. Main, Romulus, MI 48174 — verify current address with directory) during business hours (typically Mon-Fri 8 AM-5 PM, confirmed by phone) with your application, ID, and property deed. Once submitted, your permit is scheduled for plan review — 5-7 days for over-the-counter (like-for-like, no structural changes), or 2-3 weeks for material changes or structural work. Inspections are typically two: one during framing (after tear-off, before new deck fastening) and one final (after all layers are down and flashing is sealed). Some inspectors will walk the property before issuing the permit to spot-check existing layer count, which can delay issuance by 1-2 days. Budget 3-4 weeks from permit application to final sign-off if you are doing a straightforward asphalt-to-asphalt swap.

Three Romulus roof replacement scenarios

Romulus climate zone split: why your address matters for ice-and-water shield

Romulus straddles a critical Michigan climate boundary at the Huron River. Addresses south of the river (Zone 5A, lower winter design temperature -5°F) have different ice dam and snow-load requirements than addresses north (Zone 6A, lower design temperature -10°F). The IRC R905.1.1 rule requires self-adhering ice-and-water shield, but the extent varies: 5A requires it at eaves and valleys; 6A requires the same, PLUS 24 inches up the slope from the eave line. This means a north-side Romulus home in a typical cape or ranch needs more material (roughly $500–$800 extra in material and labor) than a south-side home with the same roof area.

Why the difference? Zone 6A experiences more freeze-thaw cycling and heavier snow loads, increasing ice-dam risk. The 24-inch extension is insurance against water backing up under the shingles when ice dams form. The Michigan Building Department and the City of Romulus enforce this strictly. Many roofing contractors from other states or from Livonia (which is entirely 5A) assume the 5A standard applies everywhere in Romulus and install undersized shield. This gets flagged at framing inspection, and you'll be ordered to halt and add more material, costing time and money.

To find your zone: go to the City of Romulus website or call the Building Department. They can tell you in 1-2 minutes if your address is north or south of Huron River. Alternatively, check the roof framing or existing shingle manufacturer specs on your home; if you see mention of 24-inch shield in prior permits, you're in 6A. For your permit application, state the zone explicitly and show shield placement on a sketch or in the material spec. If you don't, the permit will be held for clarification, costing 3-5 days.

Three-layer discovery: Romulus enforcement of the tear-off rule

Michigan Building Code R907.4 is unambiguous: roofs with three or more existing layers must be torn to the deck. No overlays permitted. Romulus inspectors take this seriously because multiple layers trap heat and moisture, increasing fire risk and shortening roof life. However, many homeowners and even some roofing contractors don't discover the third layer until mid-project. During framing inspection (after tear-off), the inspector counts the layers. If a third layer is found and you haven't torn it off, the permit is voided and work stops. You'll be ordered to hire a licensed contractor to tear down to the deck, which costs $1,500–$3,000 in extra labor and delays the project by 1-2 weeks.

To avoid this: ask your roofing contractor to inspect the roof from the attic or exterior soffit before you submit the permit. Use a straightedge or phone photo to document existing layers. If you find three, your permit must explicitly note 'three existing layers — complete tear-off to deck required per Michigan Code R907.4.' If you find two, note that too; this protects you because the inspector has been pre-warned. Some Romulus homes built in the 1960s-80s have three layers, and retrofitting with one additional layer was a common shortcut that is now forbidden.

Cost impact: if you discover three layers after permitting, the tear-off cost jumps to $3,000–$5,000, and the timeline stretches by 2-3 weeks. If you discover it before submitting the permit, you can budget correctly and avoid the project halt. The City of Romulus Building Department will not waive the rule, and they have no fast-track for three-layer exceptions. Budget 4-5 weeks if three layers are confirmed before permit submission.
