Frequently Ask Questions

Some of the primary causes of leaks in flat roofs are blistering, pressure ridges, exposed felts, and the accumulation of water.

Built-Up Roofing (also referred to as “asphalt and gravel” or composition roofing) has long been a trusted method for flat commercial and industrial roofs. Originating in England in the 1840s, where rainfall was abundant, this roofing system has evolved over time while maintaining its core principles.

A B.U.R. system comprises three essential components: waterproofing, reinforcing, and surfacing. These components are typically secured using hot asphalt or torch application.

  • Waterproofing ensures a dry interior.
  • Reinforcing enhances structural strength to the maximum.
  • Surfacing, often achieved by applying a top coat of asphalt covered with UV-reflecting aggregate or mineral, safeguards the underlying structure from water, light, and wind. This surfacing method is also known as ballasting.

Our proficiency in commercial roofing repairs is unmatched by few. When you choose us, anticipate a timely response and a transparent assessment of the necessary actions.

Flat roof deterioration and leaks often stem from the following factors:

  • Standing water
  • Severe winter weather
  • UV damage from the sun
  • Inadequate maintenance

These issues can lead to blisters, pressure ridges, and exposed felts, elevating the likelihood of flat roof leaks.

At Peterson Roofing, we highly recommend that all commercial building owners initiate flat roof inspections within the first year of installation and continue with annual inspections thereafter. These regular inspections not only extend the lifespan of your flat roof but also enable early detection of leaks, crucial removal of debris from the roof surface, and prevention of expensive and time-consuming emergencies in the future.
