Detroit Roof Pros provides professional roof leak diagnosis & repair in Detroit, MI for residential and commercial properties across southeast Michigan. Half the roof planes on a Detroit bungalow have no attic above the ceiling, so there is nowhere to stand with a torch and watch water arrive. The evidence is in the plaster instead, and reading plaster is a skill.
Water entering a rafter bay does not fall straight down. It runs along the underside of the board sheathing, crosses the top plate, and emerges at the base of a knee wall or in the corner of a closet that shares no wall with the wet spot at all. Homeowners chase the stain, which is reasonable and wrong. We chase the bay, which usually starts with the knee-wall access door.
Where there is no access door we make a controlled inspection cut, four inches, in a closet or an inconspicuous corner rather than the middle of a bedroom ceiling. That cut answers three questions at once: is the sheathing wet on the underside, is insulation packed hard against the boards, and is the staining old brown or fresh dark. We patch and paint whatever we open, and it is priced in.
Then we test rather than theorize. A staged hose test runs water low on the plane first and moves up in ten-minute steps, one area at a time, with somebody inside watching the opened bay. It is slow and unglamorous, and it is the only way to separate a dormer cheek from a chimney from a valley when three suspects sit within six feet of one another.
A real share of what we get called about is not a leak. Warm indoor air pushing into a cold rafter bay condenses on the board underside in January and drips exactly like rainwater, on clear days, from the same spot every winter. If that is the answer, we say so and quote the air sealing rather than new shingles. Charging for a roof repair that fixes nothing is theft with a ladder.
When it is a leak, most are cheap. Backed-out fasteners, a split pipe boot, a step flashing that stops short at a dormer return, a valley cut too tight for the water it carries. We repair those and tell you plainly how much life the surrounding shingles have left, so a two-hundred-dollar fix is never dressed up as a reason to replace a roof with years still in it.
Our licensed and insured team brings the right materials and equipment to every job — rafter-bay ventilation baffles, closed-cell spray polyurethane at the deck underside, knee-wall access panels, shed-dormer cheek-wall step flashing, plaster-and-lath ceiling planes, square-edge 1x6 board sheathing — and backs the work with a written workmanship warranty. We serve Detroit and nearby communities including Dearborn, Dearborn Heights, Livonia, Redford.

Materials, equipment and how we do roof leak diagnosis & repair
The difference between roof leak diagnosis & repair that lasts and roof leak diagnosis & repair that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with rafter-bay ventilation baffles, closed-cell spray polyurethane at the deck underside, knee-wall access panels, shed-dormer cheek-wall step flashing, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Detroit job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in southeast Michigan means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Detroit Chooses Detroit Roof Pros
- ✓We label every roof plane attic above or finished space above before we price anything, because that is what decides whether a repair or a replacement is the honest answer.
- ✓The inspection happens indoors as well as outdoors. A pin moisture meter on plaster at the knee-wall base finds what a scuttle-hole inspection structurally cannot reach.
- ✓Deck work is priced as its own line. Square-edge 1x6 board sheathing is renailed where sound and overlaid by the section where it is not, with the square footage stated.
- ✓Ventilation is quoted as a path, not a product. If the wood soffit behind your aluminum was never cut open, a ridge vent has been drawing on nothing for years.
The standards behind roof leak diagnosis & repair
Quality here is not a matter of opinion — it is written down. The roof leak diagnosis & repair work we do in Detroit follows published industry standards: NRCA publishes the Roofing Manual, the industry's reference for details and slope minimums, and Asphalt Roofing Manufacturers Association sets the shingle application and ventilation guidance the warranties reference. If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
