Flat, EPDM & TPO Roofing — Nashua, NH
Flat and low-slope roofs need a different system than pitched roofs — a watertight membrane instead of shingles. In Nashua, NH, Belgres installs and repairs EPDM rubber, TPO membrane and modified-bitumen flat roofs on homes, additions, porches and commercial buildings. As experienced EPDM and flat-roofing contractors, we build roofs that drain properly and stand up to New England snow, ice and ponding water.
Call (267) 265-1842Flat-roof systems we install
Flat and low-slope roofs rely on a continuous waterproof membrane. Belgres installs and services:
- EPDM (rubber) roofing — durable, economical and proven in New England; the go-to for many low-slope roofs
- TPO membrane — a reflective white, energy-efficient membrane with strong heat-welded seams
- Modified bitumen — tough, multi-layer asphalt systems for low-slope applications
- Flat-roof repairs — seams, flashing, punctures, blisters and ponding
- Tear-offs and re-roofs for flat roofs at the end of their life
Where flat roofs show up
It’s not just commercial buildings. Plenty of New Hampshire homes have flat or low-slope sections — over additions, porches, dormers, garages and sunrooms. These areas can’t use standard shingles, so they need a proper membrane system installed and detailed correctly. We handle both the home and commercial side.
Built to beat ponding and ice
The two things that kill a flat roof in our climate are standing water and freeze-thaw at the seams. Water that can’t drain sits on the membrane, works into any weak seam, then freezes and expands. We install fully-adhered or heat-welded systems with proper slope and drainage, and we detail the seams, flashing and penetrations carefully — because on a flat roof, the details are the roof.
Flat-roof repair done right
Most flat-roof leaks don’t need a full replacement. A failed seam, a cracked flashing or a single puncture can often be repaired to add years of life. The key is finding the real source and using materials that are compatible with your existing membrane — a mismatched patch just fails again. We diagnose the actual problem and fix it to last.

Flat / EPDM-TPO Roofing — FAQ
What is the best material for a flat roof?
For most homes and small commercial buildings, EPDM (rubber) and TPO membrane are the top choices. EPDM is proven, economical and long-lasting; TPO is a reflective white membrane with heat-welded seams that’s very energy efficient. We’ll recommend the right one for your building and budget.
How do you repair a flat roof leak?
First we find the true source — on flat roofs, leaks usually start at seams, flashing, or penetrations rather than open field. We then clean and patch or re-seam the membrane with the correct compatible materials so the repair lasts. We give a written price after inspecting the roof.
How long does an EPDM or TPO roof last?
A properly installed EPDM or TPO flat roof typically lasts 20–30 years. Good drainage and quality seam work are what determine whether it reaches the top of that range.
Why does my flat roof hold water?
Ponding water usually comes from inadequate slope or blocked drainage. Standing water accelerates seam and membrane failure, so we address drainage and detailing during installation or repair to keep water moving off the roof.
How much does a flat roof cost?
Flat roofs are usually priced per square foot and depend on the system (EPDM or TPO), the roof size and the prep involved. We give a clear written quote after a free on-site assessment.
