A Quality Job at A Fair Price
Most Popular Choice
TPO
Thermoplastic Polyolefin — the #1 flat roofing membrane on the market today. Heat-welded seams, bright white reflective surface, and built to last 20–30 years.
TPO is the most popular single-ply membrane on the market today. It's heat-welded into a single continuous sheet — meaning no seams to fail. Its bright white surface reflects sunlight and reduces cooling costs, making it an Energy Star® favorite.
- ✓ Best energy efficiency — reflects up to 80% of UV
- ✓ Heat-welded seams stronger than the membrane itself
- ✓ Lightweight — less structural load
- ✓ Resistant to chemicals, mold, and debris
- ✓ 20–30 year service life
Modified Bitumen
Color Choice Available
An asphalt-based membrane applied in layers — thick, durable, and the only flat system where you can choose your granule color to match your building's look.
- ✓ 2-ply system for redundant waterproofing
- ✓ Granulated surface — color options available
- ✓ Handles moderate foot traffic
- ✓ Works well in colder climates
- ✓ 15–25 year service life
EPDM
Ethylene Propylene Diene Monomer
EPDM is a rubber roofing membrane that's been the commercial industry standard for decades — known for exceptional long-term durability and performance in cold climates.
- ✓ Proven 20–30 year track record
- ✓ Handles extreme temperature swings
- ✓ Excellent for cold-weather climates
- ✓ Resistant to ozone and UV degradation
- ✓ Typically black (white-coated versions available)
