Low-slope commercial roofs fail differently than a residential shingle roof. Most problems trace back to a seam, a penetration, a drain or a flashing detail rather than the field of the roof itself, which is why a walk-on inspection tells you far more than a repair quote written off a photo. We evaluate the full assembly, put the findings in writing, and plan the work around your building’s schedule rather than ours.
Drains, HVAC curbs, and pipe penetrations are the most common failure points on a low-slope roof.
Membrane seams and flashing details fail before the field membrane typically does.
Interior staining on a commercial roof often means moisture has already saturated the insulation layer below the membrane.
Ponding puts sustained load on the assembly and accelerates seam failure in exactly the areas that are hardest to reach.
Low-slope systems tend to give warning before they fail outright: seams that need attention every year, flashing repairs that no longer hold, patches accumulating in the same corner. An aging system is worth evaluating on a planned schedule rather than during a shutdown.
New HVAC units, satellite dishes, or other rooftop equipment installs are a common, overlooked source of new leaks.
The roof is rarely the expensive part of a commercial roof project. The expensive part is a tenant who couldn’t open, a production line that stopped, or a customer entrance blocked by a staging area on a Friday afternoon. Those are scheduling decisions, and they get made before the first crew shows up, not during.
Before we quote, we want to know how the building is used and when it is least disruptive to work: whether crews can stage in a section of the lot without cutting off access, whether tear-off noise needs to happen outside business hours, which entrances have to stay clear, and whether the work can be phased by roof section so only part of the building is affected at a time. Where the roof layout and the building allow it, phasing is usually the difference between a project you plan around and a project that shuts something down.
A walk-on evaluation of membrane, seams, drains, penetrations and flashing, written up so you can budget from it.
Correcting the specific seam, penetration or flashing detail causing the leak, on a roof with remaining service life.
Addressing why water is sitting on the roof rather than patching the area it’s sitting on.
When the assembly has reached the point where repairs stop returning value.
Confirmed on completed work including pole-barn and light-commercial structures — see the project photos below.
Single-ply and modified bitumen low-slope systems, evaluated on the details that decide whether the roof lasts: how the membrane is attached, how seams are made, and how it terminates at parapets, curbs and drains.
Tell us about the building, roof type, and what you’re seeing.
We inspect the roof assembly — membrane, seams, drains, flashing — and discuss how work needs to be phased around your operations.
A clear, itemized scope covering repair, restoration, or full replacement.
Work is scheduled and phased to minimize disruption to tenants, staff, or operations.
Reviews below come straight from our Google Business Profile, so what you are reading is what other property owners in these towns actually wrote.
Based at 31097 Fraser Dr in Fraser, we cover most of Metro Detroit within a comfortable drive — which matters when a roof is open and the forecast changes. Don’t see your city? Ask us, coverage depends on distance and project scope.
Tear-off noise, staging and access get planned around when the building is actually in use. A quiet Saturday is often worth more to a tenant than a day saved.
The person who inspects the roof stays with the project. You are not re-explaining the building’s history to somebody new every quarter.
Many low-slope roofs have five good years left in most of the field and a failing detail at one curb. We price both paths so the decision is yours to make on real numbers.
Commercial roofs are a decade-long relationship. Ours has been under the same ownership since 2011, which means the maintenance history stays with the people who wrote it.
Parapet flashing, scupper and drain work, and the masonry around them are one water path. Splitting them between trades is how responsibility for a leak gets lost.
After a commercial job closes out, the number in your file reaches the same Fraser office that scoped it. That continuity is the point of hiring a local family business rather than a national outfit: when a seam needs looking at three winters from now, nobody has to reconstruct what was installed, because the people who installed it are still answering the phone.
We work on low-slope membrane systems as well as standing seam metal roofing. The right system for a given building depends on its slope, its rooftop equipment, how it drains and how the space below it is used, so the specific recommendation comes out of the inspection rather than out of a brochure.
Ask about scheduled inspections when you request your estimate. On a low-slope roof, most expensive failures start as something small at a seam, a drain or a curb, and looking twice a year is far cheaper than reacting once.
Yes — we plan commercial work around occupied buildings and can phase a project by section where the roof and building layout allow it. Tell us your operating hours and access constraints when you request the estimate so they’re built into the schedule from the start.
Ponding is usually a sign the roof’s drainage slope or drain placement needs correcting, not just a membrane patch. We evaluate the water path across the roof before recommending a fix.
Yes — the estimate is an itemized scope covering what we found and what we recommend, so it can go to an owner, a board or a budget cycle without translation.
Tell us about your building and roof system, and we’ll schedule a walk-through around your operating hours. You can also request a commercial estimate from our contact page.
