Why Flat Roofing

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.

Commercial Grade

We install the same TPO, EPDM, and modified bitumen systems used on major commercial buildings · proven waterproofing for any low-slope application.

Superior Waterproofing

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.

Flat Roofing FAQ

Is flat roofing suitable for residential use?

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.

What's the difference between TPO and EPDM?

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.

How do you prevent ponding water?

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.

How long does a flat roof last?

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.
