Tar and Gravel Roofing
Tar and gravel roofing, also known as built-up roofing (BUR), is a type of roofing system that consists of several layers of bitumen (asphalt or tar) and felt. The layers are bonded together to create a waterproof membrane that is then covered with a layer of gravel or other ballast material. This type of roofing is typically used for flat or low-sloping roofs and is common in commercial buildings, as well as some residential properties.
BUR roofing systems are known for their durability and long lifespan. When properly installed and maintained, a tar and gravel roof can last for up to 30 years or more. This makes it a cost-effective choice for property owners who are looking for a long-lasting roofing solution.
Maintaining Your Tar and Gravel Roof
To ensure that your tar and gravel roof reaches its maximum lifespan, it’s important to properly maintain it. This includes regular inspections to identify any potential issues, as well as routine maintenance tasks such as cleaning the roof and ensuring that drainage systems are working properly.
One common issue with tar and gravel roofs is the buildup of debris, such as leaves and branches, on the surface of the roof. This debris can block drainage systems and lead to standing water on the roof, which can cause damage over time. Regular cleaning of the roof can help prevent this issue and ensure proper drainage.
Another important aspect of maintaining your tar and gravel roof is identifying and repairing any leaks as soon as they occur. Leaks can lead to water damage and deterioration of the roofing membrane, which can reduce the lifespan of the roof. Regular inspections can help catch leaks early and prevent further damage.
The Benefits of Tar and Gravel Roofing
In addition to its long lifespan and durability, tar and gravel roofing offers several other benefits that make it a popular choice for property owners. One of these benefits is its fire resistance. The multiple layers of bitumen and felt make it difficult for flames to penetrate the roof, which can help protect the building in the event of a fire.
Tar and gravel roofing is also resistant to wind and hail damage, which can be particularly important in areas that experience severe weather. The ballast layer helps hold the roofing membrane in place, even in high winds, and can also help prevent hail from damaging the surface of the roof.
Finally, tar and gravel roofing is an environmentally friendly choice. The gravel used on the surface of the roof can be recycled, and the materials used in the roofing system are often made from recycled materials. Additionally, the reflective properties of the gravel can help reduce energy costs by reflecting sunlight and reducing heat gain in the building.
Tar and gravel roofing is a popular choice for property owners looking for a long-lasting and durable roofing solution. With proper maintenance, these roofs can last for up to 30 years or more, making them a cost-effective choice for many businesses and homeowners. In addition to their long lifespan, tar and gravel roofs offer several other benefits, including fire resistance, wind and hail resistance, and eco-friendliness. If you’re considering a tar and gravel roof for your building, be sure to consult with a professional roofing contractor to ensure that it is installed properly and maintained regularly.
