Professional EPDM Roofing
Services in New York
EPDM (ethylene propylene diene monomer) is a synthetic rubber membrane that has been protecting flat and low-slope roofs in Western New York for over 50 years. When installed correctly, EPDM handles Lake Effect snow loads, freeze-thaw cycles, and standing water that would destroy other roofing materials in months.
We install EPDM on commercial buildings, warehouses, home additions, garages, porch roofs, and any flat or low-slope section under 4/12 pitch. Mechanically fastened, ballasted, or fully adhered depending on the structure and exposure. The membrane comes in 10-foot, 20-foot, and 50-foot rolls, so we cut down on seams which are the most common failure point.
Every EPDM job starts with a roof inspection and written estimate. We check the existing substrate, drainage, and any penetrations. If the deck is sound, we install over it. If it's compromised, we tear off and rebuild. Either way you get a clear scope before any work starts, with photos and a real price.
EPDM Roof Installation
New EPDM installation in Buffalo and Rochester starts with the substrate. The deck has to be clean, dry, and level. We use insulation board (polyiso) over the deck when needed for thermal performance and to bring the surface to spec. Tapered insulation creates positive drainage on roofs that would otherwise pond water.
The EPDM membrane goes down in large sheets to minimize seams. Mechanical fasteners secure the membrane to the deck through the insulation. Seams are sealed with primer and seam tape or adhesive, then rolled to ensure full contact. Every seam is checked before we leave the site.
Flashing details around walls, drains, pipes, and curbs are critical. We use uncured EPDM flashing material that conforms to irregular shapes, sealed with EPDM-specific adhesive. Done right, a commercial EPDM roof lasts 25 to 30 years in Western New York.
EPDM Repair and Restoration
Most EPDM calls in Western New York are leak repairs. The membrane itself is durable, but seams age, flashings lift, and punctures happen from foot traffic, fallen branches, or HVAC work. We find the leak source by tracing water back from the interior damage and pressure-testing seams.
Seam repairs get cleaned, primed, and patched with new EPDM material and seam tape. Punctures get patched with circular EPDM pads sized to extend at least 4 inches past the damage in every direction. Flashing failures get rebuilt with new uncured EPDM and proper termination.
If your EPDM roof is over 20 years old and showing widespread seam failure or membrane shrinkage, repairs become patches on a roof that needs replacing. We tell you straight when it's time for a new system instead of throwing money at a roof at the end of its life.
Why EPDM Quality Matters in New York
Flat roofs in Buffalo and Rochester deal with conditions other regions don't. Lake Effect snow piles up in feet, not inches. Freeze-thaw cycles stress every seam and flashing. Ice dams form along parapets and edges. A poorly installed EPDM roof fails in two to five years here.
Quality EPDM installation in Western New York means proper drainage planning. Standing water on flat roofs accelerates membrane breakdown and overloads the structure. We design the roof to drain to scuppers or drains within 48 hours of any rainfall.
Bad seams, wrong adhesives, and improper flashings won't show on day one. They show in winter two or three when freeze-thaw pulls compromised seams apart. We follow EPDM manufacturer specs because the failures are predictable when you cut corners.
