Detroit Roof Pros provides professional commercial roofing in Detroit, MI for residential and commercial properties across southeast Michigan. The commercial work here is mostly older brick: two-story storefronts with flats above, small industrial buildings, church halls, and mixed-use blocks along the avenues. Almost all of it is low slope sitting over occupied space, which keeps our approach broadly consistent with the houses we work on.
That means we ask the same question we ask on a bungalow. What is under this deck, and how quickly does a leak become somebody's problem? A membrane over an unoccupied warehouse can reasonably wait for a scheduled replacement next year. A membrane over a tenant's kitchen or a rented flat above a shop cannot, and the maintenance interval should reflect the occupancy rather than the building's age.
We survey before we recommend anything. Core cuts at representative locations give us the layer count, the insulation type and whether it is wet, and infrared or capacitance scanning maps how far the wet area actually runs. That evidence decides between a repair program, a recover with a new cover board, and a full tear-off, and it goes into the proposal so you can follow the reasoning yourself.
On these buildings the parapet is where the money hides. Detroit brick parapets are frequently a century old, laid in soft lime mortar, capped with stone or clay coping that has shifted, and a membrane terminated somewhere behind all of it. Water entering the top of a parapet bypasses the roof entirely and appears on the top-floor ceiling, and no amount of membrane work will ever stop it.
For coverings, sixty-mil TPO mechanically attached over a half-inch high-density cover board is the workhorse wherever the deck allows it, and two-ply SBS modified bitumen is what we specify where there is heavy foot traffic, a forest of curbs, or a landlord who wants something any competent roofer can patch in ten years' time without a proprietary welder. Both get edge metal detailed to a tested standard.
Then a maintenance agreement that is genuinely work rather than a visit. Twice yearly, drains cleared and photographed, seams probed, pitch pockets topped up, curbs and terminations checked, with a dated report and a running list of what has changed since the last one. Buildings that get that outlive their membrane warranty comfortably. Buildings that do not, replace early and pay for it twice.
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 commercial roofing
The difference between commercial roofing that lasts and commercial roofing 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 commercial roofing
Quality here is not a matter of opinion — it is written down. The commercial roofing 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.
Every commercial roofing project in Detroit gets the same attention, whether it is a single room or a full commercial job. We show up on schedule, keep the site clean, and stand behind the work — the estimate is free and there is no pressure.
