Built-up Roofing: Roofing System That's Stood the Test of Time

When it comes to roofing systems, there are many options available in the market. However, some have stood the test of time, such as built-up roofing. Also known as BUR roofing, this system has been used for over a century, and it’s still a popular choice for many building owners. In this blog, we’ll discuss what built-up roofing is, its benefits, and why you should consider it for your next roofing project.

What is a Built-up Roof System?

A built-up roof system consists of multiple layers of roofing felt, coated with bitumen, and topped with a layer of gravel or a reflective coating. The layers of roofing felt and bitumen are called plies. The number of plies used in a BUR roofing system depends on the building’s size, type, and location.

Built-up roofing material has been used for over 100 years, and its popularity has only increased over the years. This is because of its durability, affordability, and versatility. Built-up roofing systems are commonly used in commercial and industrial buildings, but they can also be used in residential properties.

Benefits of a Built-up Roof System

  1. Durability: BUR roofing is known for its long-lasting durability. With proper installation and maintenance, it can last up to 30 years or more. The multiple layers of roofing felt and bitumen provide extra protection against weather elements, including rain, wind, and hail.
  2. Affordability: BUR roofing is an affordable option compared to other roofing systems. The materials used in BUR roofing are cost-effective, and the installation process is straightforward.
  3. Versatility: Built-up roofing systems can be used in a variety of applications. They can be installed on flat or sloped roofs, and they can be customized to meet the building’s specific needs.
