Roof ventilation in Detroit: what to expect
Roof ventilation in Detroit keeps the roof deck cold in winter and dry year round, which matters in older homes from Grosse Pointe to Redford. Outside air enters low at the soffits and leaves high at the ridge or roof vents. When that path is blocked or unbalanced, Metro Detroit homes get ice dams, frost on the roof boards, mold on the sheathing, and shingles that age early.
Common problems in older homes: soffits painted shut or covered by insulation, mixed vent types that short-circuit each other, and bath or kitchen fans venting into the attic. Ventilation works with attic insulation and air sealing; fixing one without the others often disappoints.
Compare Detroit roofers who check the attic before quoting vents, and see soffit and fascia for intake repairs.
What a proper job includes
- An attic check of intake, exhaust, insulation and moisture signs
- A ventilation plan balancing intake and exhaust
- Ridge vent or roof vent installation with proper cut-outs
- Opening or adding soffit intake and baffles at the eaves
- Rerouting bath and kitchen fans to the outdoors
- Removal or sealing of conflicting vents
- Photos of the attic before and after
What drives the price
- Roof shape and whether a ridge vent is practical
- Soffit condition and whether new intake is needed
- Insulation baffles and air sealing at the eaves
- Number of fans to reroute outside
- Doing the work alone or during a re-roof
- Mold treatment on sheathing by another trade

Permits and licensing in Michigan
Ventilation added during a re-roof is covered by the re-roof's building permit, and the Michigan Residential Code does not list re-roofing as exempt. Standalone vent work and fan rerouting may have separate local permit rules, so confirm with the building department where the home legally sits; in Detroit that is BSEED.
Michigan licenses home roofers through LARA as a Residential Builder or a Maintenance and Alteration Contractor, and roofing is one of the trade categories a Maintenance and Alteration license lists. A license is required when the contract price is above a threshold set by state law, so check the license number on the LARA lookup before you sign.

How to compare quotes
- Ask each roofer to explain your current intake and exhaust and what they would change.
- Ask whether soffit intake will be opened or added, not just exhaust.
- Confirm bath fans will vent outside, not into the attic or soffit.
- Check the license on the LARA lookup.
- Get the ventilation plan in writing with the vent count and type.
