What Every Detroit Homeowner Should Know About Roofing
Primary Local Risk
Freeze-thaw cycling causes repeated flashing movement and sealant failure; older housing stock has extensive flat garage and porch roofs
Material Recommendation
Heavy architectural shingles with full ice-and-water barrier; EPDM or modified bitumen for flat sections
In Detroit, roofing permits come from the Buildings, Safety Engineering and Environmental Department (BSEED). A permit guide produced with BSEED lists roof replacement, or removal of a substantial amount of shingles, as work that needs a building permit whether a contractor or the homeowner does it; the only roofing exemption is replacing a few shingles, described as roof work that could be done in a matter of minutes. Homes in Detroit's local historic districts have an additional step: the Historic District Commission must approve exterior changes, and roof replacement is specifically listed among them, so material and color choices in neighborhoods like Boston-Edison are reviewed before work begins.
Southeast Michigan winters bring repeated freezing and thawing plus occasional freezing rain; the National Weather Service's Detroit office noted a significant freezing rain event on December 26, 2025 in its winter review. Ice that builds up at the eaves is a common cause of leaks on older roofs, so roof repair in Detroit often focuses on eaves, valleys and flashing. Michigan licenses roofers through the Department of Licensing and Regulatory Affairs (LARA): roofing is one of the trades a Maintenance and Alteration Contractor license can be issued for, with the qualified trades listed on the license itself, and homeowners can check a contractor's license status with LARA before signing a contract.

How Commercial Roofing & Repair Works in Detroit
Commercial Roof Survey
A commercial roofing contractor surveys the full roof system — membrane, seams, penetrations (HVAC curbs, drains, skylights), perimeter flashings, and parapet walls. Moisture scanning identifies water trapped in insulation — a common result of extreme cold, heavy snow, and freeze-thaw roof damage on Detroit commercial buildings.
Scope & Documentation
Written scope with itemized costs, material specs, and timeline — formatted for property management review, insurance adjusters, and building owners in Detroit. Commercial documentation is more detailed than residential.
Commercial-Grade Repair
Repairs use materials matched to your existing system — heat-welded TPO, EPDM adhesive, torch-applied modified bitumen, or BUR flood coat. All penetration flashings are inspected and resealed. Work is scheduled to minimize tenant disruption.
Water Testing
Flood testing or electronic leak detection confirms the full repaired area is watertight. This step is standard for commercial work in Detroit and required by most MI property management agreements.
Warranty & Maintenance Plan
You receive workmanship warranty documentation and a biannual inspection schedule for your Detroit property. Regular maintenance is critical given the demands of extreme cold, heavy snow, and freeze-thaw roof damage on commercial flat roof membranes.
