Frequently Asked Questions

Common Questions About Flat Roofing in Suffolk County

What flat roof materials do you recommend for Long Island weather?
We typically recommend TPO roofing, EPDM roofing, or PVC roofing for most Suffolk County properties. These single ply roofing systems handle temperature swings well and resist ponding water. For commercial buildings with heavy equipment, modified bitumen roofing or built up roofing offers excellent durability. Rubber roofing is cost-effective for residential applications, while torch down roofing works well for areas with high foot traffic. We’ll assess your building’s needs and recommend the best material for your situation and budget.
If you’re dealing with isolated leaks, minor membrane damage, or issues in one area, flat roof repair is usually the right answer. Signs you might need flat roof replacement include multiple leaks, widespread cracking or bubbling, water damage inside your building, a roof that’s 20+ years old, or previous repairs that keep failing. Our roof inspection services include a thorough assessment, and we’ll give you an honest recommendation based on what we find.
Yes. Our 24 hour roof repair service covers emergency situations any time they happen. Whether it’s an active leak during a storm, sudden damage that’s letting water inside, or urgent commercial roof repair that can’t wait until Monday, we respond quickly. Emergency flat roof repair is a core part of what we do-call us whenever you need help, and we’ll get someone to your property as fast as possible.
Absolutely. We regularly provide property management roofing services and work as an HOA roofing contractor for communities throughout Suffolk County. We understand the coordination, documentation, and communication these projects require. We’ll work with your timeline, provide detailed estimates, and keep everyone informed throughout the process. Whether it’s routine flat roof maintenance or a large-scale apartment building roofing project, we make the process smooth for property managers and association boards.
Our roofing warranty covers both materials and workmanship. Manufacturer warranties on materials like TPO roofing, EPDM roofing, and PVC roofing typically range from 10 to 30 years depending on the product. We also provide a workmanship warranty on our installation and roof membrane installation work. Every project is different, so we’ll explain exactly what’s covered before we start. Our guaranteed roof repair promise means if something isn’t right, we’ll come back and make it right.
