FAQs for flat, foam, or single ply roofing installation and replacement projects in Cornwall, NY

Many roofing pros point to PVC as the top performer on flat roofs thanks to its tough seams and long-term waterproofing. A properly installed PVC membrane can last 30 years or more, resisting ponding water and harsh weather with ease. You will pay more up front than you would for EPDM, but the added durability often translates into fewer repairs and a lower cost per year of service.

Yes, a rubber roof is an environmentally friendly choice. Most rubber membranes contain recycled content and can reflect heat, which helps trim cooling bills in hot weather. Manufacturing has a lighter footprint than many traditional materials, and the long lifespan means fewer tear-offs headed to the landfill. If sustainability is a priority, ask your roofer about brands that carry third-party eco-certifications and confirm they meet local environmental standards.
