What is a Built-Up Flat Roof?

During your lifetime you have probably seen a built-up flat roof in your lifetime. But the question remains: what exactly is a built-up flat roof? Built-up roofs are referred to by their acronym, BUR. These are a very traditional kind of roof system that is usually composed of hot tar and gravel. BUR is made up of many layers and usually, the top layer is where the tar and gravel are. It is very interesting to note that out of all the flat roofs that are around today, built-up roofs are the ones that have been around the longest.

How Thick is Built-Up Roofing?

Are you wondering how thick built-up roofing is? Built up roofs are made up of many layers of integral roofing material. The roofing felts, for instance, are reinforced with either glass-fiber mats or organic mats. Felts are produced with a standard width of thirty-six inches. This equates to a metric width of about one meter. The bitumen that is used in BUR roof systems is asphalt, coal tar or cold-applied adhesive. A professional roofing company will be able to properly discuss all the layers and why they are important for the surface of your roof system.

How Do You Install Built-Up Roofing?

Are you wondering how you install a built-up roof? To begin with, roofing contractors attach base sheets to the roofing subsystem. The roofers will complete the process using roofing nails.
