Frequently Ask Questions

The most common causes of flat roof leaks are blisters, pressure ridges, bare felts, and ponding of water.

Built-Up Roofing (commonly known as “asphalt and gravel” or composition roofing) was one of the most reliable approaches for flat commercial roofing and industrial roofing applications. It was invented in England in the 1840s where it rained a lot. While the materials and technology have evolved, the basic premise remains the same.

There are 3 basic components in a B.U.R. system, waterproofing, reinforcing and surfacing. Next line: They are either secured using hot asphalt or torch applied:

  • Waterproofing keeps you dry
  • Reinforcing ensures maximum structural integrity
  • Surfacing (most often done with a top coat of asphalt covered with UV-reflecting aggregate or mineral) keeps the underlying structure protected from water, light and wind. Surfacing is also known as ballasting.

Yes, few companies can match our expertise in repairs of commercial roofing. You can expect a prompt response and an honest appraisal of what needs to be done.

The most common causes of flat roof deterioration and leaks include:

  • Standing water
  • Harsh winter weather
  • UV damage from the sun
  • Lack of general maintenance
  • These issues can cause blisters, pressure ridges, and result in bare felts that all increase the risk of flat roof leaks.
At Peterson Roofing, we recommend that all commercial building owners start getting flat roof inspections on the first year they are installed, and continue with annual inspections every year thereafter. These inspections can help prolong your flat roof’s lifespan, and provide the opportunity for early flat roof leak detection, vital debris removal from the roof surface, and avoiding costly and time-consuming issues down the road as the result of emergencies.
