Flat
Roofing.
EPDM, TPO, and Built-Up Roofing (BUR) installations for low-slope and flat roofs across Southern Wisconsin. Built for garages, additions, commercial buildings, and multi-family properties.
EPDM, TPO & BUR
Three industry-leading flat roofing systems — each with distinct advantages depending on your building type, budget, and performance goals.
Commercial flat roof — membrane surface with integrated HVAC.
EPDM Rubber Roofing
EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber membrane proven for decades on flat and low-slope roofs. Highly resistant to UV, extreme cold, and Wisconsin freeze-thaw cycles.
- 45–90 mil membrane thickness options
- Lifespan of 25–30+ years with proper maintenance
- Excellent low-temperature flexibility
- Cost-effective for larger flat roof areas
- Fully adhered, mechanically fastened, or ballasted install
TPO Single-Ply Membrane
TPO (Thermoplastic Polyolefin) is the fastest-growing flat roofing system in the industry. Heat-welded seams create a watertight bond superior to glued or taped alternatives.
- 60–80 mil membrane options
- Reflective white surface — energy savings in summer
- Heat-welded seams for superior waterproofing
- Resistant to punctures, tears, and chemical exposure
- Ideal for commercial and low-slope residential
Built-Up Roofing (BUR)
BUR is one of the oldest and most reliable flat roofing systems — multiple layers of reinforcing fabric and bitumen topped with a protective gravel or cap sheet surface. Exceptional durability and redundancy.
- Multiple reinforcing ply layers for added strength
- Excellent puncture and impact resistance
- Gravel or smooth cap sheet finish options
- Proven system with 20–30+ year lifespans
- Great for high-traffic commercial rooftops
