Systems we install
The right membrane for your building
TPO
Heat-welded, bright white membrane that reflects summer heat. A common choice for commercial roofs and homes that want lower cooling costs.
EPDM (rubber)
Durable synthetic rubber with a long track record on rowhouses, garages and rear extensions.
Modified bitumen
Multi-layer asphalt-based system (APP/SBS) that handles foot traffic well, a good fit around HVAC units and roof access.
PVC
Heat-welded membrane that resists grease and chemicals, often used on restaurants and buildings with rooftop equipment.
Coatings & restoration
Renews an aging roof that is still sound, adding reflectivity and years of life without a full tear-off.
Tapered insulation
Builds slope into a flat roof to stop ponding water and adds insulation to meet energy code.

FAQ
Flat roofing questions
What is the best flat roof membrane for my building?
It depends on how the roof is used, sun exposure, foot traffic, rooftop equipment and budget. We compare TPO, EPDM, modified bitumen and PVC for your building and explain the trade-offs in writing.
Can you fix ponding water?
Yes. We correct ponding with tapered insulation, added or relocated drains, or re-pitching, so water leaves the roof instead of sitting on it.
How long does a flat roof replacement take?
Most residential flat roofs take 1–2 days. Larger commercial roofs are staged over several days to keep the building dry and open.
Can you work around tenants or business hours?
Yes. We plan staging and access around occupants and offer after-hours and weekend scheduling.
Do you handle permits and inspections?
Yes. We manage municipal permits and manufacturer inspections as part of the job.
Do you offer emergency flat roof repair?
Yes. For active leaks we offer 24/7 emergency service. Call (718) 981-7663.
