Choosing the right commercial roofing system is a critical financial decision that can make or break your bottom line. Knowing what kind of roof works best for your business or facility is part of running a successful commercial property. Among the many options available, built-up roofing (BUR) systems have a time-tested reputation for being durable, long-lasting, and relatively affordable. What is a BUR roof, and what makes it such a popular choice for commercial roofing systems?
What Is a BUR Roof Used For?
Built-up roof (BUR) systems are one of the most popular, time-tested flat roofing systems used today. What is a BUR roof used for? BUR roofs are ubiquitous in commercial and industrial applications. They are the roofing choice for some of the most successful businesses in America: visit nearly any Walgreens in the country, for example, and you’ll see a BUR roof.
BUR roofs are a type of flat roof, and flat roofs are the most popular style of roof used in commercial applications. Commercial roofing systems differ from residential roofing systems in several ways. Unlike residential roofs, which tend to be pitched, commercial roofs are typically flat. Flat roofs are more accessible and more cost-effective to install on large buildings than pitched roofs, and they provide other practical benefits as well:
- Flat roofs are more accessible than pitched roofs.
- Flat roofs can maximize space and storage (many companies install heating and cooling equipment there).
- Flat roofs are easier to maintain and repair than pitched roofs.
Besides BUR roofing systems, some of the most common flat roofing materials you’ll find for commercial use include ethylene propylene diene monomer (EPDM) roofs, modified bitumen (MB) roofs, polyvinyl chloride (PVC) roofs, and thermoplastic olefin (TPO) roofs.
How Are BUR Roofs Constructed?
Commercial roofs differ in size, pitch, and function from residential roofs, so the materials used to construct them differ, too. BUR roof membranes are constructed of multiple alternating layers of hot asphalt and sheets of reinforcing fiberglass felt. These waterproof layers are sealed together with hot asphalt, and a cap sheet or layer of gravel is then applied on top of the asphalt for extra security and to protect against sun damage and physical wear.
Benefits of a BUR Roof
Durability
BUR roofs are heat, UV, and impact-resistant. Their reliable durability allows them to withstand inclement weather and daily wear and tear.
Longevity
The materials used to create a BUR roof — stone and asphalt — create a roof that endures and performs for the long haul. BUR roof systems are among the longest-lasting roof systems available. A well-constructed and properly installed BUR roof lasts 20 years or more. Some contractors estimate that each additional layer added to a BUR roof may extend its lifespan by five years.
Ease of Maintenance
One of the most appealing qualities of a BUR roofing system is its easy maintenance. Repairing or maintaining more complex roofing systems can be costly and time-consuming, while BUR roof repairs are generally simple and inexpensive, usually only requiring replacing layers of asphalt.
Long-Term Affordability
BUR roofs are relatively affordable compared to other flat roofing options, but remember that they are still a significant investment. Materials used in constructing a BUR roof’s layers and the time required to install a BUR roof properly can affect the upfront cost. Business owners can often get a BUR roof installed for between four and seven dollars per square foot. While you can find cheaper roofing systems, remember that the durability, longevity, and lack of required maintenance for BUR roofs can help make every dollar you spend last.
Other Considerations
BUR roofs are only suitable for some applications. If you’re looking at commercial roofing options, keep these considerations in mind:
- Due to their layers of material, BUR roofs are very heavy, so a building’s structure must be able to support a BUR roof’s weight.
- Proper installation of a BUR roof is a time-intensive process that requires skilled contractors with experience in the layering process.
- Asphalt can be brittle, and the longevity and durability of a BUR roof depend on proper installation.
