Residential Flat Roofing

Professional Residential Flat Roofing in New Jersey

Flat and low-slope areas — porches, additions, dormers, and modern flat-roof homes — need a very different system than shingles. As a GAF-certified contractor, we install the GAF Liberty™ Self-Adhered Roofing System, built around a self-adhering SBS-modified bitumen base ply and matching cap sheet. Because it peels and sticks with no torch, hot asphalt, or open flame, it is a cleaner, safer choice for occupied homes — while delivering the rugged, watertight protection a low-slope roof demands.

What's Included

  • GAF Liberty™ self-adhering SBS membrane
  • No torch or open flame — safer for your home
  • Ideal for porches, additions & low-slope roofs
  • Fiberglass-reinforced for dimensional stability
  • Granulated cap sheet in multiple colors
  • Backed by GAF manufacturer warranties
