Flat and low-slope roofs are common on many New Jersey homes, additions, and commercial buildings. They require different materials and expertise than sloped roofs. If you have a flat roof, here's what you need to know to keep it in great shape.

Common Flat Roofing Materials

The most popular flat roofing systems include EPDM (rubber), TPO, and modified bitumen. Each has its own strengths in terms of durability, energy efficiency, and cost. A professional can recommend the best option for your building.

Why Drainage Matters Most

Because flat roofs don't shed water like sloped roofs, proper drainage is essential. Standing water — called ponding — is the number one enemy of a flat roof and can lead to leaks and premature failure if not addressed.

Common Flat Roof Problems

Flat roofs are prone to ponding water, membrane cracks and blisters, seam failures, and flashing issues. Regular inspection catches these problems before they cause leaks.

Maintaining Your Flat Roof

Keep drains and scuppers clear, inspect the membrane for damage, and address any ponding or seam issues promptly. Routine maintenance dramatically extends the life of a flat roof.
