What Does Hiring Rooftoppers Mean for You?

What it means is that you are hiring a reputable roofing company with a good standing in the community and we will be here for you when you need us for all your roofing repairs, replacements and warranty needs now and for years to come. Hiring an experienced roofer doesn’t mean casually selecting a random name from some list. It’s imperative that you find a roofing contractor with the knowledge and expertise needed for your particular situation. And one who is properly licensed and insured in the State of California. If you don’t, and you end up having to file an insurance claim, your homeowner’s insurance might not cover the damage because you used an unlicensed contractor. This is just one example of how not knowing something can land you in a whole heap of trouble, as well as having to pay for a major unplanned expense! Don’t let this be you.


What is a Built-Up Hot Asphalt Roof?

A built-up roof, also commonly referred to using the acronym BUR, is a roof that’s made with built-up layers of tar and gravel. This type of roofing system is composed of alternating layers of bitumen and reinforcing fabrics that are formed to make a roofing membrane. Their fabrics are also known as felts or ply sheets and are reinforced with glass-fiber mats or organic mats. Then after each fabric layer has been added, a finishing layer of aggregate is applied as a top coating. Built-up roofing is most commonly used on low-slope roofs such as commercial, industrial and institutional buildings.

The Different Types of Built-up Roofing

There are several different types of built-up roofing applications that can be used. Here is a general overview of each.

  • Smooth asphalt built-up, hot or cold, which is heated then applied with a mop or some other type of mechanical spreader
  • Ballasted asphalt built-up, which provides a great finish and is a good fire-retardant agent
  • Bitumen, which is asphalt, coal tar or a cold-applied adhesive

The Benefits of a Built-Up Roofing Application

Built-up roofing systems are time tested and used extensively in new construction. They’re also one of the most common types of commercial roofing systems used around the globe. Built-up roofing applications are extremely popular for many reasons, such as:

  • Offer exceptional water intrusion protection
  • Provides protection from ultra-violet rays
  • Very low maintenance and easy to repair
  • Stronger against inclement weather than other materials
  • Are less expensive over their life cycle
  • Provides multi-layer protection
  • Can be used on any type of roof deck
