Most commercial buildings have flat or low-slope roofs — and they need a different approach than a house. Dee's Roofing installs and maintains membrane systems built to drain and last.
Strip malls, warehouses, office buildings, restaurants and many churches and schools around Knoxville have flat or low-slope roofs. These roofs can't rely on steepness to shed water, so they depend on a continuous membrane, well-planned drainage and careful detailing at every edge, wall, curb and penetration. Dee's Roofing provides flat and low-slope roofing for commercial property owners across East Tennessee.
We install EPDM rubber membranes and other low-slope systems suited to your building, budget and how the roof is used. Large roofs often have rooftop HVAC units, vents, skylights and drains, and each of those needs to be flashed correctly to keep the roof watertight for years.
As a family-owned, licensed and insured roofing contractor headquartered in Powell, we'll give you a straight recommendation — whether that's a new system, a repair or a protective coating to extend the life of a roof that's still sound.
These details determine how well a commercial flat roof performs.
Drains, scuppers and gutters that move water off the roof quickly.
Properly bonded seams across large roof areas.
HVAC curbs, vents and pipes flashed to stay watertight.
Secure edge metal and parapet flashing that resist wind and water.
A commercial flat roof is a significant investment, and the right system depends on your building — its size, how much foot traffic the roof sees, the equipment on top, and your budget.
We'll walk you through the options and help you plan, whether you need a full replacement now or want to extend the life of your current roof with repairs, maintenance or a coating.
Regular inspections are especially important on low-slope roofs, where small seam or drainage problems can grow quickly. We can help you stay ahead of them.
Here's what Dee's offers for commercial flat and low-slope roofs.
