Roofing & Waterproofing in NYC
Serving the Bronx, Queens, and Nassau County. Licensed and insured. Free estimates.
A reliable roofing and waterproofing system is the most important investment you can make to protect your property. Doon Construction Corporation installs, repairs, and maintains roofing and waterproofing systems for residential and commercial buildings across the Bronx, Queens, and Nassau County.
We work with all major flat roofing systems including modified bitumen, EPDM rubber membrane, TPO, and PVC single-ply systems. For pitched roofs, we install architectural shingles, slate, and metal roofing. Each material is selected based on your building type, budget, and performance requirements.
Water damage is the most expensive problem a property owner can face. Our waterproofing systems create multi-layer barriers against moisture infiltration. We apply advanced membrane systems, liquid waterproofing, and foundation drainage solutions tailored to each building's specific conditions.
Every roofing project starts with a thorough inspection to assess your current roof's condition. We document existing damage, identify potential problem areas, and recommend the most cost-effective solution. Our proposals include transparent, itemized pricing - no hidden fees or surprise charges.
We handle projects of every size, from emergency leak repairs to complete roof replacements on multi-story commercial buildings. Our team works efficiently to minimize disruption to building occupants, and every project is backed by manufacturer warranties and our own workmanship guarantee.

Roofing & Waterproofing Questions
What type of roofing is best for NYC buildings?
For most NYC commercial and multi-family buildings, flat roofing systems like TPO, EPDM, or modified bitumen are the best choice. For residential homes, architectural shingles or slate provide durability and aesthetic appeal. We recommend the best option based on your building type and budget.
How long does a flat roof last in New York?
A properly installed flat roof in NYC lasts 15–25 years depending on the material. Modified bitumen averages 15–20 years, EPDM 20–25 years, and TPO 20–30 years. Regular maintenance and inspections can extend roof life significantly.
How much does roof replacement cost?
Flat roof replacement in the NYC area typically costs $8–$15 per square foot depending on the material and building access. A 2,000 sq ft roof replacement ranges from $16,000 to $30,000. We provide free on-site estimates with exact pricing.
