Commercial Roofing in Taylor, MI
New commercial and industrial buildings in Taylor, MI go through the Planning Department, which oversees land-use planning and zoning across the city and coordinates development review under the city master plan. A roof on a building under review is a set of decisions made on paper: slope, drains, insulation thickness, penetrations and the path crews will use to maintain it. The condition that changes everything is drainage, because a flat roof that cannot shed snowmelt becomes a maintenance problem in its second winter.
The work starts at the roof assembly and moves outward. For an existing building, we map the water path, check the membrane field and details, and document the remaining service life. For a roof still on paper or a major reroof, the assembly is checked against the Michigan code in force and the owner receives written options with prices.
Roof Decisions in Development Review
Development review sets the building footprint, the use and the site layout. The roof decisions that follow are the owner's and the design team's, and several of them are hard to change later. The first is drainage: where the low points sit, how many drains serve each area and where overflow paths lead. A second is insulation, which sets the roof's thermal performance and also the height of every curb and flashing above it.
The third decision is equipment placement. Every rooftop unit adds a curb, a gas or electrical penetration and a service path. Putting units over the middle of the roof, away from the edge and drains, keeps maintenance crews on the field instead of the perimeter. We review those choices with the owner and the roofing sub, and write down the assumptions that govern the roof. When a drawing leaves a detail ambiguous, we ask for a clarification before material is ordered, because a question on paper costs far less than a leak in service.
Checks During New Roof Installation
On a new roof, the work is inspected as it is built. We look at the deck before insulation goes down: dry, clean, fastened and free of gaps. We check each layer of insulation for staggered joints and secure attachment, then the membrane for seam width, adhesion and fastener spacing. Curbs and penetrations are flashed in sequence as the field is installed, not after it, so the details are tied into the membrane rather than patched onto it.
Photographs at each stage create a record the owner can use later. Weather matters as well. Membranes and adhesives have temperature and moisture limits, and frost or a wet substrate means the crew waits. A TPO roof, an EPDM roof and a modified bitumen roof each have their own installation limits, and the plan names the one that governs. At closeout, we test drains, walk the roof and deliver written findings with a punch list. The owner receives the roof plan with each curb and drain numbered, so a service call years later can name the exact detail in question.
Existing Roofs Before a Change
An owner of an existing building who is leasing, selling or changing its use has the roof sitting in the middle of that decision. We inspect in sequence: drains, field, seams, curbs, edges. The written findings sort the roof into sections by condition, and each section is paired with a recommended action and a price range.
When the owner is deciding between repair and replacement, the question is wet insulation. A roof with dry insulation and a few failed details supports a repair, and one with wet board across a wide area does not. A moisture survey maps the wet areas, and cores confirm what the scan shows. The report then states the remaining service life and what a repair would buy, tied to a reading and never to the age of the roof alone. A recover is considered only where the existing assembly is dry and the structure can carry another layer.
Snow, Thaw and Drain Performance
Snowfall at the Dearborn station totals 30.8 inches in a normal year, mostly November through April, and design snow loads still need code-specific checks for each site. For a roof, the practical test comes at the first thaw, when meltwater moves to the drains. A drain bowl that is partly blocked holds water against the membrane, and any weak seam at the low point lets it in.
With 35.05 inches of annual precipitation and about nine to twelve days of measurable precipitation in most months, a roof in this region is wet often. Frequent wetting reveals weak details quickly and also keeps the roof from drying out between events, which matters for a coating or a patch that needs a dry surface. We schedule repairs for dry windows, place temporary protection when the weather will not cooperate and tell the owner when the permanent repair is expected, along with what the temporary measure covers in the meantime. A drain and scupper check is part of every visit.
Code, Energy and Documentation
Michigan's 2021 building code took effect on April 9, 2025 and the 2021 commercial energy code on April 22, 2025. Depending on scope, the energy code can reach roof replacement and insulation work, so the local enforcing office's position comes first. We put those assumptions into the scope so that the price and the design match.
Documentation does the rest. A roof plan, a set of photographs and a written list of findings give an owner what a lender, an insurer or a buyer will ask for. A roof condition report carries that information in one place. Owners with buildings in Romulus, Southgate or Wyandotte use the same format, so the files for different properties can be compared directly.
Commercial Roofing Questions
How early in a project should a roofing contractor review the roof design?
Before drawings are final. Drainage, insulation thickness and equipment placement are easy to change on paper and costly to change after steel and decking are in. A short review catches clashes like a unit sitting over a drain or a curb set too low for the insulation, while the designer can still fix them cheaply.
What is the most common defect found on newly installed roofs?
Flashing details at penetrations and edges, because they are built by hand at the end of a day. We look for unsealed laps, loose termination bars and curb flashings that were not tied into the field sheet. A punch list at closeout lists each one.
Should an owner pay for a roof survey before leasing a building?
If the roof's condition affects who pays for repairs, yes. A survey with moisture readings and photographs sets a baseline and can be attached to the lease, so a dispute later has a record to rely on. It costs less than the dispute it prevents.
When does a coating make sense?
When the membrane is sound, the insulation is dry and the surface can be cleaned and prepared. Coating seals the surface and extends service life, yet failed seams and wet board stay failed. We repair those first, then price the coating against recover and replacement.
What documentation should an owner expect after a repair?
Photographs before and after, a roof plan marking the work area, a description of the materials and a note on any condition left for monitoring. Together they let the owner show an insurer or buyer what was done and why.
