3 Things To Know About Built-Up Roofing Systems

Posted on: 7 July 2019

If you are in the process of constructing a commercial building and are deciding on what type of roof it should have, it can be hard to know what kind to choose. Some of the more common types of commercial roofing systems include single ply membrane, standing seam metal roofing, shingle roofing, and sloped roofs. One more type of roofing that is becoming increasingly popular is called a built-up roofing system.

Here are three things to know about built-up roofing systems.

1. Know How Built-Up Roofing Systems Are Made

Used primarily on roofs with a low slope, built-up roofing systems are also known as BUR. This type of roof consists of alternate layers of fabric and asphalt. These layers are combined to form a membrane and then covered with gravel or stone.

Because of the materials used, they are often referred to as tar and gravel roofs. The layers provide a stable surface as well as optimum protection from the elements.

2. Know How Much Maintenance Is Required

When it comes to different roofing systems, one of the first questions asked is how much maintenance it will require. As with other types of roofing systems, as long as regular inspections are done and problems are caught early, maintenance for built-up roofing systems is relatively low.

There are some things that should be taken care of as soon as the problem arises. This includes things like loose areas on the roof or cracks on the surface. If membrane deterioration is causing blisters on the roof, this should be dealt with right away as well. When properly maintained, built-up roofing systems have the potential to last up to 40 years.

3. Know the Benefits

Another reason certain types of roofs are chosen over others is due to the kinds of benefits they provide. Some benefits of a built-up roofing system include:

  • They are durable and have a proven track record.
  • There are no seams, which makes it virtually waterproof and reduces the risk of leaking.
  • The aggregate used on the top makes it resistant to fire and offers protection from UV rays.
  • When gravel is used on the top layer, it provides traction for those working on the roof.

One more benefit that built-up roofing systems have to offer is that this type of roof can be made from a variety of materials. This makes it possible for commercial building owners to construct a roofing system that best suits their particular needs.
