Commercial Roofing

Commercial Roofing Services We Provide

Our commercial roofing services cover the full life of a roof, from a new building to a worn-out system and the repairs in between.

Commercial Roof Installation

New construction and additions need a system designed for the building’s slope, insulation requirements and rooftop equipment. Our commercial roof installation work covers system selection, insulation, flashing at every curb and penetration, and final inspection.

Commercial Roof Replacement

When patching costs keep climbing, a commercial roof replacement resets the clock. We remove the old system, inspect the deck and insulation, replace anything wet or damaged, and install a new roof built to current code.

Commercial Roof Repair

Leaks, open seams, punctures, failed flashing and ponding water are repairable on most roofs that still have life left. Our commercial roof repair crews find the source, fix it and document the work, including on roofs another company installed.

Storm Damage and Emergency Leaks

Hail, wind and fallen limbs can open a roof in minutes. We stabilize active leaks first through our emergency roof repair service, then document the damage for your insurance carrier before permanent repairs.

Commercial Flat Roofing Systems We Install

Commercial flat roofing is not one product. The right system depends on the deck, slope, foot traffic, rooftop equipment and budget. These are the systems we work with most.

TPO Single-Ply Membrane

A white, heat-welded membrane that is one of the most common choices for low-slope commercial roofs. The welded seams form a continuous sheet, and the reflective surface helps keep upper floors cooler in summer.

EPDM Rubber Membrane

A proven rubber membrane that stays flexible in cold weather, which suits Midwest winters. It can be mechanically fastened, fully adhered or ballasted, depending on the building.

Modified Bitumen

A multi-ply asphalt-based system with strong puncture resistance. It is a good fit for roofs with regular maintenance traffic around equipment.

Built-Up Roofing

Layers of asphalt and reinforcing felts, a long-standing system on large flat roofs. We repair and replace built-up roofs and can recommend whether to stay with built-up or move to a single-ply system.

What Midwest Winters Do to Low-Slope Roofs

A flat roof in our region spends months under snow. Around Grand Rapids, yearly snowfall averages 77.6 inches under the 1991-2020 normals, and buildings downwind of the Great Lakes see bursts of lake-effect snow that can stack up quickly. On a commercial roof, that snow does not sit evenly. It drifts against parapet walls, rooftop units and higher roof sections, which is where loads and leaks concentrate.

Melting is its own problem. Snowmelt that cannot reach a drain freezes overnight, and clogged or iced-over drains leave water ponding on the membrane. Repeated freezing works at seams and flashing around curbs and penetrations. Experienced commercial roofing contractors look hardest at drains, scuppers, perimeter metal and the flashing around every unit before winter, because that is where most cold-weather leaks begin.

Michigan Energy Code, Permits and Re-Roofing Rules

A commercial re-roof in Michigan is permitted work, and the rules changed in 2025. The state began enforcing a new commercial energy code on April 22, 2025, based on ASHRAE 90.1-2019 or the 2021 IECC with Michigan amendments, and it applies to projects that need a commercial building permit. Local building departments list the same dates; the City of Battle Creek’s codes-in-effect list shows the 2021 Michigan Building Code effective April 9, 2025, with the energy rules following on April 22.

Why that matters for a roof: under the energy code, a replacement on a roof whose insulation sits entirely above the deck generally has to meet the insulation levels for new construction, as the International Code Council explains in its guidance on roof replacement requirements. That can add tapered or extra insulation to the scope, which affects edge heights, curbs and drains. The building official makes the final call, so we confirm the requirement during the permit process rather than guessing.

Recovering an existing roof is also limited. Building codes generally do not allow a new roof over one that is water-soaked or already has two roof coverings, a point the building enclosure industry summarizes clearly. And because Michigan ties building permits to state contractor licensing, as the Bureau of Construction Codes notes, confirm who is pulling the permit before work starts. We handle permitting as part of every commercial project.

Repair, Recover or Replace?

We start every commercial evaluation by figuring out how much life the roof has left and whether the insulation underneath is still dry. From there, the decision usually falls into one of three paths.

• Repair when problems are isolated, the membrane is sound, and the insulation is dry. Repairs plus regular maintenance can add years to a roof.
• Recover when the existing roof is dry, has only one covering and the deck is sound. A new membrane over the old system can save on tear-off costs, within code and manufacturer limits.
• Replace when the insulation is wet, leaks are widespread, the roof already has two coverings, or repair costs keep adding up. As a general rule, once repairs approach 25 to 30 percent of replacement cost, replacement is usually the better long-term investment.

Whichever path fits, the commercial roofing contractors you hire should put the recommendation and the reasoning in writing. We do, so you can share it with owners, boards or tenants.

What Commercial Roofing Costs

Commercial roofing contractors price work by the square foot, and the range is wide. HomeAdvisor’s 2026 data puts TPO roofing at roughly $4.50 to $16 per square foot installed, and larger commercial projects with tear-off and added insulation can run higher. Treat that as a starting point only; we price your building after a site visit.

The main cost drivers on a commercial project:

• Tear-off versus recover, and how many existing layers come off.
• Wet insulation and deck repairs found once the old roof is opened.
• Insulation required by code, including tapered insulation to correct drainage.
• Penetrations and equipment: curbs, vents, skylights and units that need flashing or temporary lifting.
• Access and scheduling, such as crane time, work around business hours or phased sections.

Our Commercial Roofing Process

Commercial jobs follow the same eight-step process as our residential work, adapted for occupied buildings:

1. Free site visit and roof assessment. We walk the roof, check drains, flashing and equipment curbs, and photograph problem areas.
2. System recommendation. We explain the options that fit your building and budget, with the tradeoffs in plain language.
3. Written scope and one project manager. A detailed scope of work and a single contact for owners, managers and general contractors.
4. Permits and scheduling around operations. We pull permits, plan staging and set work hours or phases to limit disruption.
5. Tear-off, deck and insulation check. Damaged deck and wet insulation are replaced before new materials go down.
6. Installation. Insulation, membrane, flashing at every penetration, and new perimeter metal installed to manufacturer specifications.
7. Cleanup and final walkthrough. Debris removed daily, and a roof walk with you at completion.
8. Warranty and documentation. Written labor warranty, manufacturer warranty paperwork where it applies, and photo documentation for your records. Warranty coverage details are provided with your estimate.

Frequently Asked Questions About Commercial Roofing in the Midwest

Property owners and managers ask us these questions most often when planning a roof project.

Does a commercial re-roof in Michigan have to meet the new energy code?

Often, yes. Michigan began enforcing its updated commercial energy code on April 22, 2025, and a roof replacement on a building with insulation entirely above the deck generally has to bring that insulation up to the levels for new construction. Your building official makes the final call, and we confirm it during permitting.

Can a new membrane be installed over our existing roof?

Sometimes. A recover is only an option when the existing roof is dry, has just one covering and sits on a sound deck. If the insulation is wet or the building already has two roofs, building codes generally require a full tear-off.

Should we have snow removed from our flat roof?

Only when drifts or ice build up beyond what the roof was designed for, and only by a crew trained to work on snow-covered roofs without damaging the membrane. We can inspect the roof once it is safe to access. Shovels and ice picks cause a lot of winter leaks. Keeping drains and scuppers clear so meltwater can leave the roof matters more than clearing every inch.

How often should a commercial roof be inspected?

We recommend an inspection at least twice a year, in spring and fall, plus a check after any major storm. A fall inspection catches clogged drains and open seams before snow season, and a spring inspection finds winter damage while it is still a small repair.

What types of commercial properties do you work on?

Retail strips and centers, warehouses, medical and professional offices, multi-unit residential buildings, assisted living facilities and HOA-managed properties. If your building has a low-slope or flat roof, we can evaluate it.
