Flat Roofing

Flat and low-slope roofs fail differently than a pitched shingle roof — drainage and membrane detail are what make or break them.

Whether it's a home addition, a covered porch, or a full commercial building, flat and low-slope roofs need the right membrane system and proper drainage to perform. We install and repair TPO, EPDM, and modified bitumen systems sized and sloped correctly for the structure.

What’s included

  • TPO, EPDM, and modified bitumen membrane systems
  • Drainage and slope assessment to prevent ponding water
  • Flashing detail at walls, curbs, and penetrations
  • Residential additions and porches as well as commercial buildings
  • Leak diagnosis and targeted repairs
