Commercial & Flat Roofing in New Baltimore, Michigan
Low-slope roofs over New Baltimore storefronts, offices, and marinas 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.

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.
New Baltimore sits along Anchor Bay on Lake St. Clair in eastern Macomb County, 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 New Baltimore 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 water
A flat roof in New Baltimore 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 sitting on Anchor Bay 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. New Baltimore's open-water exposure only adds to that wind risk on a low-slope roof.
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 New Baltimore 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. Read more on our storm and insurance claims page. Every visit, storm-related or routine, starts with a free inspection and ends with an honest, written recommendation.
04 /How a New Baltimore commercial job actually runs
Commercial work has to fit around a business, so scheduling gets talked through up front: after-hours access, staged material drops, and keeping drains and walkways clear for staff and customers while the crew works. A free inspection starts the process, walking the whole roof field, every drain, every penetration, and every seam, and it ends with a written scope and price, not a verbal guess. Property managers and landlords covering multiple buildings get the same written documentation for every roof in the portfolio, which makes budgeting for next year's capital plan a lot less of a guessing game. We serve New Baltimore businesses with the same licensed and insured crews, the same published price canon, and the same free inspection we use across Macomb County.
Documentation matters as much as the work itself on a commercial roof. Every inspection we do comes with photos of the deck, the membrane, and every drain and penetration we checked, filed the same way whether the visit turns into a repair, a coating recommendation, or nothing at all. That paper trail is useful for more than deciding what to fix next: it is what a lender wants before financing a purchase, what an insurer wants before renewing a policy, and what protects a landlord or property manager if a tenant ever asks when the roof was last checked. If financing a larger tear-off makes more sense than paying out of a maintenance budget in one shot, options are available subject to approval; as an illustration only, a $13,500 project is about $178/mo on a 10 year term at 9.9% APR.

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