Built-up Roofing

BUR Flat Roofs

Built-up roofing, also known as BUR or tar and gravel, is a reliable, cost-effective roofing system that has been used for well over one hundred years in the construction industry. It is widely known for its durability, versatility, and resistance to water, UV rays, fire, extreme temperatures, and harsh weather.

A BUR is usually made by building up at least three layers of different roofing materials on top of each other. This system is designed so that each layer is applied one at a time with the next one being heated and rolled onto the previous layer. The first layer is a base sheet that is usually mechanically fastened with screws and washers. Then, subsequently, other layers are built up on top by alternating layers of bitumen, also known as tar or asphalt, and reinforcing fabrics such as fibers and felts, thus creating a strong and durable bond and waterproof membrane barrier. To top it all off, the final layer is typically ballasted with a layer of gravel or mineral granules to provide added protection from the elements.

Advantages

The benefits of a Built-Up Roof include its strong and durable construction, its cost-effectiveness, and its ability to withstand heavy rain, snow, and other extreme weather conditions. This type of roofing system is also relatively low-maintenance. It does not require frequent repairs or replacements and can be easily cleaned with a garden hose. Best yet, it can last up to 40 years with proper maintenance, making it a great long-term solution for any commercial or residential property.

Disadvantages

While known for its many advantages, there are also a few disadvantages to an asphalt and gravel roof. One of the main disadvantages is that it can be relatively heavy, which can make it difficult to install on certain types of structures. Additionally, this roofing style is not suitable for every climate and can be relatively expensive to install, which can make it less affordable for some property owners.

Another disadvantage of built-up roofing is that it can be relatively difficult to repair or replace. This is because the multiple layers of materials used in this type of roofing system make it difficult to access the underlying layers, which can make repairs or replacements more difficult and time-consuming.

Despite these disadvantages, tar and gravel roofs are still considered to be one of the best options for flat roofing systems. Their ability to withstand extreme temperatures and weather conditions, their durability and longevity, along with their low maintenance requirements, make them an ideal choice for property owners who are looking for a reliable and long-lasting roofing system that can withstand the elements and protect their property.
