Built-up Roofing Systems for Commercial Roofing

Built-up roofing, often referred to as BUR for short, is among one of the most commonly installed commercial roofing systems used in America, due to its wide variety of protection purposes and classically acclaimed durability.

Built-up Roofing: The Basics

Built-up roofing systems are made up of two central ingredients, both serving a specific and important purpose. Bitumen, which you may identify as asphalt or coal tars, provides the roof with waterproofing and strong adhesion, while ply sheets, or “felts”, prevent the roof from tears, punctures, and other damage. Usually, these BUR surfacing elements are coated to fend against UV radiation, early aging, and even to minimize indoor heating and cooling expenses.

Built-up roofing systems are sometimes called “tar and gravel” roofs, as they are normally comprised of the bitumen materials asphalt, coal tar, or cold-applied adhesive. However, the coating and materials used on the roof solely depends on your desired results and your budget.

The two most common built-up roofs are flat Asphalt built-up, either hot or cold, and Ballasted Asphalt built-up. Asphalt built-up was at one time more popular in comparison to Ballasted, but recently, the demand for Ballasted asphalt has spiked due to its superb finish surface and its ability to deter fire.
