Detroit encourages cool roofs and energy-efficient construction through the Michigan Building Code, BSEED permitting, and incentive programs tied to the Climate Strategy. Reflective roofing reduces urban heat island effects and lowers air-conditioning demand in Detroit summers.
Cool roofs use reflective membranes or coatings that bounce sunlight back, keeping buildings cooler. Detroit follows Michigan Building Code 1502 and the 2015 Michigan Energy Code, which set minimum insulation and reflectivity for low-slope commercial roofs. BSEED reviews reroof permits and may flag noncompliant materials. The Climate Strategy and DTE rebates offer incentives for upgrades, especially in heat-vulnerable neighborhoods like North End, Southwest, and Eastside. Residential cool roofs are voluntary, but commercial buildings over a certain size must meet code reflectivity targets at reroof time. Permits run through the BSEED ePermits portal at detroitmi.gov.
Installing a noncompliant commercial roof without permit can trigger stop-work orders and require tear-off and replacement, plus BSEED reinspection fees ranging $200–$1,000.
