Watertight Protection for Low-Slope Roofs
Shingles need a slope to shed water. Flat and low-slope roofs don’t have that advantage, so they rely on a continuous, sealed membrane to keep water out. When a flat roof is installed poorly, water ponds on the surface, finds the smallest seam, and leaks into the structure below.
KRC Roofing & Siding installs flat roofing systems designed to stay watertight. That means quality membranes, carefully sealed seams, proper flashing at walls and edges, and drainage planned so water moves off the roof instead of sitting on it.
Flat Roofing Systems We Install
EPDM (Rubber Roofing)
A tough, flexible synthetic rubber membrane with a long track record. It handles Iowa’s temperature swings well and is easy to repair.
TPO
A white, heat-welded membrane that reflects sunlight to keep buildings cooler. Its welded seams are strong and watertight.
Modified Bitumen
A multi-layer, asphalt-based system that’s highly durable and resistant to foot traffic. It’s a good fit for roofs that get regular use.
Where Flat Roofing Is Used
- Porches and covered patios.
- Garages and carports.
- Home additions and sunrooms.
- Dormers and low-slope sections of pitched roofs.
- Modern homes with flat roof designs.
- Commercial and multi-family buildings.
Installed to Stay Watertight
Every flat roof we install includes removal of the old roofing, inspection and repair of the roof deck, insulation where needed, the new membrane with fully sealed seams, and flashing at every wall, edge, and penetration.
Flat and Rubber Roofing FAQs
How long does a flat roof last?
It depends on the system and installation quality. Well-installed EPDM and TPO roofs commonly last 20–30 years with routine maintenance.
What's the best flat roof for Iowa?
EPDM is a proven performer in cold climates thanks to its flexibility. TPO offers energy savings with reflective surfaces and strong welded seams. We’ll recommend the best fit for your building.
Why does water pond on my flat roof?
Ponding usually comes from poor slope, clogged drains, or sagging decking. When we replace a flat roof, we correct drainage so water flows off properly.
How much does a flat roof replacement cost?
The cost depends on roof size, the system you choose, insulation needs, and the condition of the deck. We provide a free, itemized estimate.
