Ponding water
A flat roof that does not drain holds water that finds every seam and works through any weak point. We address slope and drainage, with tapered insulation where needed, not just the membrane on top.

A flat roof is not really flat, it just has too little slope to shed water the way a pitched roof does, which means it has to be sealed rather than shingled. Flat and low-slope roofs show up on commercial buildings, modern homes, additions, porches, and garages, and they fail in different ways than a steep roof, almost always at a seam, a penetration, or a low spot that holds water.
We install and repair every common low-slope system, TPO, EPDM, modified bitumen, and spray foam, and the right one depends on the building and how it is used. The membrane matters, but the drainage and detailing matter more. We scope the whole roof, not just the surface, so water has somewhere to go and nowhere to sit.
Low-slope systems we install
- TPO single-ply membrane
- EPDM rubber membrane
- Modified-bitumen and built-up systems
- Spray polyurethane foam
- Tapered insulation for positive drainage
- Edge metal, curb, and penetration detailing
Why flat roofs fail
Seams and penetrations
Nearly every flat-roof leak starts at a seam, a curb, or a pipe. We weld or detail these correctly so they are the strongest part of the roof, not the weakest.
The wrong system for the building
TPO, EPDM, modified bitumen, and foam each fit different buildings. Putting the wrong one on a roof guarantees an early failure. We match the system to the use.
Our Method
How we handle low-slope roofs
- 01Assess the deck, drainage, slope, and penetrations before recommending a system.
- 02Recommend TPO, EPDM, modified bitumen, or foam based on the building and budget.
- 03Correct drainage with tapered insulation where water ponds.
- 04Install with welded or fully adhered seams and proper edge metal.
- 05Detail every curb, drain, and penetration to the manufacturer spec.
Straight Pricing
What flat roofing costs
Flat-roof pricing is driven by square footage, the system, the insulation, and the condition of the existing roof. We price per square foot after an on-site assessment, because drainage and tear-off work vary so much from one roof to the next.
On a building you plan to hold, a maintenance program is a small annual cost that catches ponding, seam, and flashing issues early and meaningfully extends the life of a low-slope roof.

Straight Answers
Flat Roofs questions, answered.
It depends on the building and how it is used. TPO offers welded seams and a reflective surface; EPDM is durable and cost-effective on simpler roofs; modified bitumen suits roofs with foot traffic; foam adds insulation and seamless coverage. We assess your roof before recommending one rather than defaulting to a single system.
Almost always because of ponding water or a failed seam or penetration, not the field of the membrane. A flat roof that does not drain will keep finding new weak points. We fix the drainage and detailing, not just the visible leak.
Isolated seam or flashing failures on a sound membrane can often be repaired. A membrane that is brittle, widely seam-split, or ponding across the roof usually needs replacement. We will tell you honestly which one your roof needs after an inspection.
