Flat Roofing in Minnetonka, MN
Flat roofs fail for a predictable reason: water sits where it shouldn't. Getting the slope and membrane detail right the first time is what keeps a low-slope section dry for years instead of months.
Flat and low-slope roofing shows up on additions, porches, garages and some commercial-style buildings around Minnetonka. We install EPDM, TPO and modified asphalt systems depending on the size of the section, the traffic it gets, and your budget.
The biggest cause of flat roof failure isn't the membrane itself, it's ponding water. If a flat section doesn't drain properly, water sits on the surface, finds the smallest seam or flaw, and works its way in over time. We check and correct the slope and drainage as part of any flat roof project, not just lay a new membrane over the same bad pitch.
Seams, flashing at walls and curbs, and penetrations for vents or skylights are where most leaks start on a flat roof. We detail those areas carefully since they take the most stress from temperature swings and standing water.
If you're pairing a flat roof section with a larger pitched roof replacement, like on a home with an attached flat porch roof or addition, we coordinate both so the transition between the two systems is handled correctly rather than treated as an afterthought.
For small commercial or mixed-use buildings in the area, flat roofing often means balancing budget against expected building life. We'll walk you through EPDM versus TPO versus modified asphalt so you're choosing based on your actual situation, not just the cheapest option.
Flat roofing work carries our 100% satisfaction guarantee, and we'll go over manufacturer warranty terms for whichever membrane you choose.

Flat Roofing FAQ
Why does my flat roof keep leaking even after a repair?
Repeat leaks usually mean the underlying slope or drainage wasn't corrected, so water keeps finding the same weak spot. A patch over a bad pitch is a temporary fix. We check drainage as part of any flat roof repair or install.
What's the difference between EPDM and TPO for a small building?
EPDM is a dark rubber membrane that handles freeze-thaw cycling well and is easy to repair. TPO is a reflective white membrane that can help with cooling in summer. Size, budget and rooftop equipment all factor into which makes more sense for your building.
Can a flat roof section be added to a home that's otherwise pitched?
Yes, this is common on additions, porches and garages. We detail the transition between the flat and pitched sections carefully since that's a common leak point if it's not handled correctly.
How long does a flat roof membrane last?
It depends on the material, installation quality, and how well the roof drains. A properly sloped and detailed membrane will significantly outlast one that's fighting ponding water from day one.
Do you work on small commercial flat roofs too?
Yes, alongside our residential flat roofing work we handle small commercial and mixed-use buildings in the area, with the same focus on drainage and detailing.
