EPDM rubber, TPO, and modified bitumen flat roofing for homes, garages, additions, and commercial buildings across Western MA and Northern CT. Free inspection. Fast response.
Flat Roof Systems
We'll tell you which system is right for your building, your budget, and your climate. No upsell. Just the right answer.
The most proven flat roof system. A single sheet of synthetic rubber covers your entire roof with no seams. Lasts 40 to 50 years with minimal maintenance. Best for residential flat roofs, garages, and additions.
The most popular commercial flat roof system. The bright white surface reflects heat and can cut cooling costs by up to 30%. Welded seams are stronger than adhesive. Best for commercial buildings and large flat surfaces.
A layered asphalt system that has been used for decades. Extremely durable in New England freeze-thaw cycles. Can be torched, cold-applied, or self-adhered. Best for low-slope roofs with complex penetrations.
Real Results
New membrane, proper drainage, and a clean finish. This is what we deliver for homeowners and businesses across Western MA and Northern CT.


Failed membrane, pooling water, and active leaks into the building.
Warning Signs
If you see any of these, call us for a free inspection before the damage gets worse.
Flat roofs should drain within 48 hours. If water sits longer, your drainage is blocked or the roof has settled. Standing water accelerates membrane breakdown.
Water stains on your ceiling directly below a flat roof section mean the membrane has failed. Bubbles in the membrane mean moisture is trapped underneath.
UV exposure and freeze-thaw cycles cause EPDM and modified bitumen to crack over time. Cracks let water in immediately.
A failing flat roof loses its insulating value. If your heating or cooling costs have gone up, your flat roof insulation may be wet and compromised.
Wet insulation under a flat roof grows mold fast. If you smell something musty in a room below a flat roof, call us before the damage spreads.
Most flat roof systems last 20 to 30 years. If yours is approaching that age, a free inspection will tell you exactly how much life is left.
