Michigan's roofing market is shaped by one of the most varied climates in the Midwest. The Upper Peninsula deals with extreme snowfall and cold, while the Lower Peninsula experiences significant lake-effect snow near the Great Lakes shorelines, hot and humid summers, and active spring storm seasons. Detroit and the surrounding suburbs represent the largest roofing market in the state, with a dense stock of older homes in active replacement cycles. Ice damming is a common concern across much of Michigan, and hail damage drives meaningful insurance activity each year. Michigan does not have a statewide roofing contractor license requirement, making these 21 questions to ask a roofing company especially useful when vetting contractors.

Roofing in Michigan: What Homeowners Should Know
Michigan homeowners face roofing challenges that shift significantly by region. Lake-effect snow communities near Lake Michigan, Lake Huron, and Lake Superior deal with some of the highest snowfall totals in the country, while southeastern Michigan near Detroit sees more moderate winters but still faces ice damming and freeze-thaw wear. Summer hail events across the southern Lower Peninsula generate significant insurance activity each year. Roof replacement cycles of 20 to 25 years are realistic for quality installations in Michigan's climate.
Michigan Roofing Contractor Licensing
Michigan does not require a specific statewide roofing contractor license, but contractors performing residential work must be registered as a Residential Builder or Maintenance and Alteration Contractor through the Michigan Department of Licensing and Regulatory Affairs (LARA). You can verify a contractor's registration at michigan.gov/lara. Always confirm that your contractor carries current general liability and workers' compensation insurance before work begins.
Michigan Building Codes and Permit Requirements
Michigan follows the Michigan Residential Code, which is based on the IRC with state amendments. Permits are required for full roof replacements throughout the state. Local building departments in Detroit, Grand Rapids, Lansing, and other municipalities administer permits and inspections independently. Contact your local building department to confirm requirements and fees before starting any roofing project.
Call Before You Dig
Michigan law requires notification to MISS DIG 811 at least three business days before any digging. Call 811 or visit missdig811.org. This applies to any ground disturbance associated with a roofing, drainage, or gutter installation project.
