Commercial & Flat Roofing in Romeo, Michigan
Romeo's shops, offices, and outbuildings mostly carry a different kind of roof than the houses around them: a low-slope membrane instead of pitched shingle. 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 Romeo, from a single-ply membrane replacement on a small shop to a full tear-off with tapered insulation on a larger building. 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.
A commercial building in Romeo rarely has the same roof as the house next door to it. Retail storefronts, small offices, and standalone outbuildings tend to sit under a membrane stretched over a mostly flat deck, draining sideways to internal drains or edge scuppers instead of shedding water down a pitch. That difference matters if you own or manage one of those buildings. A flat roof over a leased space or a working property is a budget line and a liability, and the smart move is knowing exactly what system is up there 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 Romeo 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 holds up well underfoot, which suits roofs that see regular foot traffic to rooftop mechanical 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.
Matching the system to the building
The right choice depends on the building more than any general rule. A smaller Romeo storefront or standalone shop with a lot of parapet and flashing detail often does well with modified bitumen or a fully adhered EPDM system, while a larger office or light-industrial building with a wide-open field of roof may lean toward TPO for the reflectivity and welded-seam reliability. We walk through what is already on your building and what its condition actually supports before we ever recommend tearing it off.
02 /Why flat roofs fail in this part of Macomb County
A flat roof in Romeo has to handle two things a sloped shingle roof mostly does not: standing water and a hard freeze-thaw cycle that repeats all winter across Macomb County. 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 the ground or behind a parapet wall.
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 Romeo 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. Our roof replacement page covers the tear-off process in full.
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 shop or damages equipment underneath. 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; our storm and insurance claims page covers documentation in more detail. Every visit, storm-related or routine, starts with a free inspection and ends with an honest, written recommendation.
The point of an inspection is not to sell you a new roof. It is to tell you the cheapest thing that will keep the water out, and to say so in writing.
04 /Working around business hours and a working property
A commercial roof project in Romeo rarely gets to happen on an empty building. Shops stay open to walk-in customers, offices run on business hours, and a light-industrial property or outbuilding has its own operating schedule to protect. We plan tear-off, staging, and material delivery around your hours where we can, keep the work area contained, and coordinate with property managers on notice to tenants before crews show up. On a membrane replacement that involves hot work or adhesives, we also flag anything that needs advance notice to neighbors so the smell or noise is not a surprise.
Documentation matters as much as the work itself on a commercial building. A written scope, photos of the tear-off and the new membrane before it is covered, and a copy of the manufacturer's warranty give a property owner a paper trail for insurance, for a future sale, and for the next roofer who eventually inspects the building. We leave every Romeo commercial customer with that paperwork, not just an invoice.

Questions we hear most
Most flat and commercial roof projects in Romeo 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 Romeo 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.
