Commercial & Flat Roofing in Chesterfield, Michigan
Low-slope roofs over Chesterfield storefronts, offices, and warehouses fail differently than a house roof, and cost more when they do. We inspect, repair, coat, and replace TPO, EPDM, and modified bitumen systems, and tell you which one your building actually needs, in writing.
covers most flat and commercial roof projects in Chesterfield, from a single-ply membrane replacement on a small building to a full tear-off with tapered insulation. Targeted repairs run $350 to $3,200, with larger or complex work higher. See the full breakdown on our pricing sheet, or run your own number on the cost calculator.
Chesterfield sits on the Macomb County shore of Lake St. Clair, and the commercial buildings along its corridors carry the same low-slope roofs you find on any strip mall, office building, or small warehouse anywhere in southeast Michigan: a membrane stretched over a mostly flat deck, draining sideways to internal drains or edge scuppers instead of shedding water straight down a pitch. That difference matters for a business owner or property manager. A flat roof over a leased space or a working building is a budget line and a liability, and the smart move is understanding the system you have before a leak sets the schedule for you.
01 /TPO, EPDM, or modified bitumen: what's likely on your roof
Most commercial and flat roofs we look at in Chesterfield are one of three systems, and each has a different price, lifespan, and failure mode. TPO is a white, reflective single-ply membrane with heat-welded seams; a good weld is stronger than the membrane itself, while a cold or skipped weld is exactly where a TPO roof leaks first. EPDM is the black rubber membrane that has covered flat roofs for decades, adhered or ballasted with seams that are taped or bonded rather than welded; it stays flexible through a Michigan winter, though its dark color adds to summer cooling loads. Modified bitumen is an asphalt-based membrane installed in layers, and it is tough underfoot, which suits roofs that see regular foot traffic to rooftop equipment. A restoration coating over an aging but still sound membrane is worth asking about too, since it can add years of service life for less than a full tear-off, as long as the deck and insulation underneath are still dry.

02 /Why flat roofs fail near the lake
A flat roof in Chesterfield has to handle two things a sloped shingle roof mostly does not: standing water and a hard freeze-thaw cycle that repeats all winter, and being close to Lake St. Clair adds moisture-heavy air to that mix for much of the year. A flat roof drains because it is built with a slight pitch toward drains or scuppers, not because it sits level, and over the years insulation compresses and low spots form that hold water for days after a rain. That ponding accelerates membrane aging and keeps steady pressure on the nearest seam. Winter adds the second problem: water that works into a seam or sits near a drain freezes, expands, and pries the flaw open a little more every cycle, and a blocked drain backs meltwater onto the field where the membrane was never meant to hold a pond. Macomb County's August 2023 severe weather, which led to a federal disaster declaration (FEMA DR-4757), is a reminder that wind and hail damage low-slope commercial roofs too, lifting membrane edges and denting flashing in ways that are easy to miss from ground level.
03 /Repair, coat, or replace: the honest fork
The decision is not always replacement. If the membrane is mid-life and the damage is localized to a seam, a flashing, or a drain, a targeted repair is the right call, and most run $350 to $3,200 depending on the system and the detail. If the membrane is aging but the deck and insulation underneath are still dry, a restoration coating can buy years at a fraction of a tear-off's cost. Replacement earns its place when seams are failing across the roof, insulation has taken on water, or ponding has worked into the deck; a full flat or commercial replacement in Chesterfield runs $9,000 to $16,000, with square footage, membrane type, and how much the drainage has to be rebuilt moving the number inside that range.
The cheapest dollar spent on a commercial roof is a maintenance dollar. Semiannual inspections, plus a look after any major storm, catch the open seam or clogged drain while it is still a caulk-gun problem instead of an interior leak that closes a suite or damages a tenant's inventory. If a storm did the damage, we document it with photos and can meet your adjuster on site to walk the roof together, though no honest contractor can promise how a carrier will rule on a claim. Every visit, storm-related or routine, starts with a free inspection and ends with an honest, written recommendation.

Questions we hear most
Most flat and commercial roof projects in Chesterfield run $9,000 to $16,000, depending on square footage, the membrane system, and whether drainage or insulation has to be rebuilt. Targeted repairs are far less and typically run $350 to $3,200, with larger or complex work higher. We give you a written price after a free on-site inspection, with no obligation.
Neither is simply better; they trade off. TPO is a white, reflective membrane with welded seams that can help hold down cooling costs on a large roof, while EPDM is a black rubber membrane with a long track record that stays flexible in Michigan cold. The right choice depends on your building and budget, and we walk through both during a free inspection rather than pushing one product.
Most flat roof leaks in Chesterfield are a repair, not a replacement, because they start at a seam, a flashing, or a drain rather than across the whole field. If the membrane is mid-life and the deck underneath is dry, we fix the detail that is leaking. When seams are failing everywhere or the insulation is wet, replacement is the better spend, and a restoration coating is sometimes the right middle option, which an inspection tells us.
