Common Questions
Frequently Asked Questions
How long does a flat roof last? +
EPDM typically lasts 20 to 30 years. TPO lasts 15 to 25 years. Modified bitumen lasts 15 to 20 years. Proper maintenance extends all systems significantly. See our
summer roof maintenance 9-point checklist for what to do every year.
Why is my flat roof leaking? +
Common causes include failed seams, cracked flashings, ponding water, clogged drains, or membrane blistering. We offer free leak assessments.
What's the difference between EPDM and TPO? +
EPDM is black rubber, extremely durable and cheaper. TPO is white thermoplastic, energy efficient and ideal for NYC's hot summers. Both are excellent choices.
Can you fix a flat roof without full replacement? +
Often yes. Isolated leaks, seam repairs, and coating applications can extend a roof's life 5 to 10 years without full replacement.
Do you do commercial flat roofs? +
Yes. We handle residential rowhouses, apartment buildings, and small commercial properties throughout Brooklyn and the outer boroughs.
How do you fix ponding water on a flat roof? +
Ponding water (water that sits longer than 48 hours after rain) accelerates membrane failure and voids most warranties. We fix it by adding tapered insulation to create positive slope, installing additional drains or scuppers, or applying a reinforced roof coating system over the low spots.
Do you install roof coatings over existing flat roofs? +
Yes. A good roof coating (silicone, acrylic, or elastomeric) can extend a flat roof's life by 10 to 15 years and is dramatically cheaper than full replacement. Coatings also reflect heat, reducing cooling costs. We assess whether your roof is a good coating candidate during our free inspection.
Can you handle storm damage and insurance claims for a flat roof? +
Absolutely. We document damage with photos and moisture readings, provide the detailed scope of work insurance adjusters require, and work directly with your carrier. Most storm damage claims in Brooklyn are for wind lifted membrane, hail damage, or fallen debris.
