Do You Need a Permit for a Roof Repair in Michigan?

Building permits in Michigan come from the Stille-DeRossett-Hale Single State Construction Code Act. Section 125.1510 says that, except as otherwise provided in the code, the owner or the owner's builder, architect, engineer or agent must apply for a building permit before construction of a building or structure. The act's definition of construction is broad and includes repair.

The same section then carves out the exception that matters here. Subsection (7) reads, in full: "A building permit is not required for ordinary repairs of a building or structure." The act does not define "ordinary repairs," which is why the code and your local building official fill in the details.

The code's definitions chapter separates four kinds of roof work. The difference matters, because the permit question and the code requirements change with each.

The ordinary-repair exemption in the construction code act has one big blind spot: local historic districts. If your home sits in a historic district created by your city or township under Michigan's Local Historic Districts Act (1970 PA 169), a separate permit can be required for exterior work that the building code would never notice.

Section 5 of the Act (MCL 399.205) says a permit shall be obtained before any work affecting the exterior appearance of a resource is performed within a historic district, and that the work shall not proceed until the historic district commission has acted by issuing a certificate of appropriateness or a notice to proceed. In reviewing plans, the commission follows the U.S. Secretary of the Interior's standards for rehabilitation and considers the compatibility of design, texture and materials.

The definitions decide whether a roof repair counts. The Act defines work to include repair, and says a repair that changes the external appearance of a resource constitutes work. It also defines ordinary maintenance, keeping a resource in good condition through ongoing minor intervention without changing its external appearance except by removing the usual effects of weathering, and says ordinary maintenance is not work. Replacing a few shingles in a matching color is likely to land on the maintenance side; changing shingle color or material, swapping slate or wood for asphalt, or removing a chimney is likely to need a certificate.

Commissions can delegate approval of specified minor classes of work to staff or the building inspector (MCL 399.205(10)), so simple in-kind repairs are often approved quickly. A decision can be appealed to the State Historic Preservation Review Board within 60 days. Listing on the National Register by itself is a different thing, so ask your city whether your address is in a local district before work starts.

This describes the statute and is not legal advice; your local commission's ordinance and guidelines control the details.

The permit application ties the job to a licensed contractor. Under MCL 125.1510, a residential builder or maintenance and alteration contractor applying as the owner's agent must file written authorization and list their license number and its expiration date. That puts the contractor's name on record as the party responsible for the work.

The Michigan Attorney General's home repair guidance lists "contractor asks you to pull any required permits" among the warning signs of a home repair scam, and suggests asking any contractor whether the work requires a permit and settling who is responsible for permits before work begins. A homeowner permit is generally meant for an owner doing their own work. Stellar Roofing Company is a Michigan Licensed Residential Builder, license #262000779, and you can look up any roofer's license on LARA before you hire.

A permit is not just a fee. It brings an inspection by someone who works for the public, it creates a record of when the work was done, and that record helps later with buyers, appraisers and insurers. Skipping a required permit can mean redoing work, a stop-work order, or questions at sale time. On the other hand, nobody needs a permit for a pipe boot in most places, and a contractor who insists on one for every small repair may simply be padding the bill.

If you are unsure, the cheapest move is the phone call. The building department will tell you what applies to your address, and you can hold your contractor to that answer.
