Flat roofing doesn't mean perfectly level—it's a low-slope system (typically 1/4 inch per foot) designed to shed water. In Paterson, where annual rainfall averages 47 inches and winter temps drop below freezing, a properly installed flat roof is critical. We use modified bitumen, TPO, EPDM, and built-up roofing (BUR) systems, each with specific benefits for your home or business.
Materials We Use for Flat Roofs
Modified Bitumen (Torch-Down)
This asphalt-based material comes in rolls and is heat-welded for a seamless membrane. Cost range: $4.50–$7.00 per square foot installed. Lifespan: 15–20 years. Best for residential flat roofs with foot traffic.
TPO (Thermoplastic Polyolefin)
Energy-efficient white membrane that reflects UV rays. Cost range: $5.50–$8.50 per square foot. Lifespan: 20–25 years. Excellent for Paterson's summer heat waves.
EPDM (Rubber)
Synthetic rubber membrane, highly flexible in cold weather. Cost range: $4.00–$6.50 per square foot. Lifespan: 20–30 years. Ideal for low-budget projects.
Built-Up Roofing (BUR)
Multiple layers of asphalt and felt, topped with gravel. Cost range: $5.00–$9.00 per square foot. Lifespan: 20–30 years. Traditional, heavy-duty option for commercial buildings.

Local Climate Considerations
Paterson's freeze-thaw cycles (average 90 days below freezing) cause flat roof membranes to contract and expand. Our installation includes expansion joints and tapered insulation to prevent cracking. We also reinforce flashing against nor'easter winds that can peel loose edges. Snow loads are calculated to 30 psf per local code.
