Commercial-grade flat and low-slope roofing systems for businesses, additions, and residential properties across the Hudson Valley.

From commercial projects to residential flat roofing, J&A Roofing installs quality flat roofing systems using trusted products from Firestone and Carlisle · selected for durability, warranty coverage, and long-term performance.
Modern flat roofing systems have come a long way. Today's commercial-grade membranes offer decades of reliable waterproofing for both businesses and residential additions.
We install the same TPO, EPDM, and modified bitumen systems used on major commercial buildings · proven waterproofing for any low-slope application.
Properly installed flat roofing membranes form a seamless, watertight barrier that outperforms multi-component systems on low-slope surfaces.
With periodic inspections and basic care, a quality flat roof membrane can last 20-30 years with minimal upkeep compared to multi-layer systems.
We install flat roofing systems from the most trusted names in commercial waterproofing, with manufacturer-certified warranties backed by proper installation.
Absolutely. Modern flat roofing systems work excellently on additions, garages, porches, and contemporary homes. We assess the structure and slope to recommend the right system for your application.
TPO is a white thermoplastic membrane known for energy efficiency and heat-weld seams. EPDM is a black rubber membrane with a long track record of durability. Both are excellent · the right choice depends on your building type, climate exposure, and budget.
Proper drainage design is critical on flat roofs. We ensure correct slope-to-drain, specify appropriate drain locations, and use tapered insulation where needed to prevent standing water from accumulating.
Quality TPO and EPDM systems last 20-30 years with proper installation and maintenance. Some PVC and Sarnafil systems are rated beyond 30 years. Regular inspections every 2-3 years keep small issues from becoming expensive repairs.
