Commercial and flat roofing

A leaking roof over a business costs more than the repair. It costs inventory, equipment and days you cannot open. We install and repair TPO, EPDM rubber and metal roofing on shops, warehouses, offices and flat roofed buildings across the Miami Valley.

Roof systems

TPO, EPDM and metal roofing systems

Most commercial buildings have a flat or low slope roof, and the right system depends on the building, the budget and how long you plan to own it.

TPO

A single ply membrane with seams that are heat welded together, which makes them some of the strongest seams in flat roofing. Usually white, so it reflects summer sun and helps keep the building cooler.

EPDM rubber

A synthetic rubber membrane with decades of track record on commercial roofs. It handles freeze and thaw cycles well and is straightforward to repair. Usually black, with seams joined by adhesive and seam tape.

Metal

Steel panel roofing for commercial and agricultural buildings and steeper roofs. Long lasting, fire resistant and well suited to large, simple roof shapes.

Repair or replace

Does your flat roof need repaired or replaced?

Signs it is time to replace

  • Leaks keep showing up in different spots across the building.
  • The membrane is cracked, shrinking or pulling away at the edges.
  • The insulation underneath is wet, which you can often feel as soft spots when you walk the roof.
  • The roof has been patched so many times the patches are failing.

Signs a repair will do

  • One leak you can trace to a seam, a curb or a penetration like a vent or HVAC unit.
  • Storm damage limited to one area of an otherwise sound roof.
  • Flashing that has pulled loose at a wall or parapet.

Where flat roofs fail

Common commercial roof problems

Ponding water

Water still standing 48 hours after it rains is a warning sign. It ages the membrane faster and adds weight the roof was never meant to hold, and it usually points to a drainage or structure issue worth fixing.

Seams

Seams are where membranes are joined, and they are the first place a flat roof leaks as it ages.

Penetrations and curbs

Every vent, pipe, drain and HVAC unit is a hole in the roof. The flashing around them takes a beating from weather and service crews walking the roof.

Drains and scuppers

Leaves and debris clog drains, and a clogged drain turns a flat roof into a pond.

Edges and parapets

Wind gets under loose edge metal and starts peeling the membrane back from the outside in.

Pricing

What determines commercial roofing cost

Roof size

Measured on site, in squares of 100 square feet.

System

TPO, EPDM and metal each carry a different material and labor cost.

Tear off or recover

A sound, dry roof can sometimes be covered with a new membrane, which costs less. A wet or failing roof has to come off.

Insulation and drainage

Wet insulation gets replaced, and tapered insulation can be added to move water toward the drains.

Penetrations

Each HVAC unit, vent, skylight and drain adds flashing work.

Access

Building height, roof access and where materials can be staged.

Working with you

Commercial roofing that works around your business

We schedule the work with you to keep disruption down, keep the site clean, and keep you updated while the crew is on the roof. When a storm damages a commercial roof, we document the damage with photos and work alongside your insurance company, the same way we do for homeowners. See our storm damage page for how that works.

Questions

Commercial roofing FAQs

How long does a flat roof last?
TPO and EPDM roofs commonly last 20 to 30 years when they are installed well and maintained. Metal roofs often last longer. Drainage and regular inspections make a big difference either way.
Should I choose TPO or EPDM?
TPO reflects heat and has welded seams, which makes it a strong choice for buildings that run air conditioning. EPDM has a long track record and is easy to repair. We will recommend the one that fits your building and budget.
Can you repair a flat roof without replacing it?
Often, yes. Seams, flashing and punctures can usually be repaired if the rest of the roof is sound. We will tell you honestly whether a repair makes sense or just delays a replacement.
Do you work on flat roofs on homes?
Yes. Porches, additions and other low slope sections on houses usually use the same rubber or TPO systems. For the rest of the roof, see our roof replacement and roof repair pages.
