Commercial roofing contractors handle flat and low-slope roofs differently than residential pitched roofs. Most commercial buildings use membrane systems—TPO, EPDM, or modified bitumen—installed over nearly flat or gently sloped decks. These commercial flat roofing systems require different materials, installation methods, and maintenance approaches than residential asphalt shingles.

We coordinate schedules to minimize business disruption. Early morning installations, phased replacement over multiple weekends, and clear communication about access restrictions help keep your operations running.

We've completed commercial roofing projects for over 10,000 customers across 25+ years in Ohio and 3 years in Michigan. That experience includes everything from small office buildings to larger retail plazas and industrial facilities.

TPO (Thermoplastic Polyolefin)
Light-colored membrane that reflects heat. Heat-welded seams create watertight bonds. Energy-efficient choice for commercial flat roofing where cooling costs matter.
Common applications: Office buildings, retail, warehouses with HVAC equipment on the roof.

EPDM (Rubber Membrane)
Dark rubber membrane with a long performance track record. Flexible enough to handle freeze-thaw cycles without cracking. Seams are taped or glued.
Common applications: Light industrial, smaller commercial buildings, budget-conscious replacement projects.

Modified Bitumen & BUR
Asphalt-based systems applied in layers. Typically shorter lifespan than TPO or EPDM but lower material costs upfront.
Common applications: Buildings where budget is the primary driver and owner plans shorter hold periods.

Localized damage from HVAC equipment, known leak sources around penetrations, or isolated membrane tears. If the bulk of your commercial flat roofing is sound and you're addressing specific problem areas, commercial roof repair costs less and causes minimal disruption.

Roof size → Larger buildings spread mobilization costs over more square footage. Small roofs (under 5,000 sq ft) see higher per-square-foot pricing.

System type → TPO commercial roofing and EPDM fall in similar cost ranges. Modified bitumen typically costs less in materials but requires more labor. Premium systems with thicker membranes add cost.

Layers to remove → Tear-off increases labor time and disposal fees. Some projects allow overlay if the existing deck is sound and local codes permit.

Deck condition → Replacing rotted plywood or damaged insulation adds material and labor before new membrane goes down.

Complexity → Roof penetrations (HVAC units, vents, skylights), parapet walls, and drainage issues all increase labor time for proper flashing and waterproofing.
