Flat Roofing
Flat Roof Installation & Replacement
The right system for your home. Installed correctly the first time.
Flat and low-slope roofing requires a different approach than pitched roofs — different materials, different drainage requirements, and different failure points. We install systems that actually perform in Minnesota's climate.
- EPDM, TPO, modified bitumen, and PVC systems
- Drainage designed for Minnesota freeze-thaw cycles
- Lower cost than pitched systems of comparable size
- Clear, honest assessment before any work begins

Our Approach
Why Flat Roofing Requires Specialized Installation
Flat roofs work differently than pitched roofs. Water doesn't shed by gravity — it has to be actively managed through drains, scuppers, and slope built into the system itself. The consequences of a poorly installed flat roof are typically faster and more damaging than a pitched roof failure.
Minnesota's freeze-thaw cycles create additional stress. Water that pools even slightly and then freezes can compromise seams, damage drains, and work through any weak point in the membrane. Proper drainage design is as important as the material itself.
Systems We Install
Flat Roofing Systems We Install
EPDM (Rubber Roofing)
A synthetic rubber membrane that's been the residential flat roofing standard for decades. Highly flexible in cold temperatures — critical for Minnesota's freeze-thaw cycles.
TPO (Thermoplastic Polyolefin)
Single-ply thermoplastic with heat-welded seams that form a continuous watertight bond. White reflective surface reduces summer cooling loads.
Modified Bitumen
A reinforced asphalt membrane applied in multiple layers. Good durability and puncture resistance, installed using heat application or self-adhering systems.
PVC Roofing
Premium single-ply membrane with excellent chemical resistance and heat-welded seams. Higher upfront cost but a strong option for specific drainage or exposure challenges.
Benefits
Benefits of Modern Flat Roofing
- Lower installation cost than comparable pitched systems

Investment
Flat Roofing Cost in the Twin Cities
Typical 2025–2026 pricing for Minnesota residential and light commercial flat roofing, installed:
- EPDM$5–$8 / sq ft
- TPO$6–$10 / sq ft
- Modified Bitumen$5–$9 / sq ft
- PVC$8–$12 / sq ft
Lifespan varies by system: EPDM 20–30 years, TPO 15–25 years, modified bitumen 15–25 years, PVC 20–30 years. Drainage quality, installation workmanship, and how quickly minor issues are addressed all strongly influence actual lifespan.
