Tar and Gravel Roofing: A Time-Tested Solution for Your Roofing Needs
When it comes to roofing materials, tar and gravel may not be the first option that comes to mind. However, this traditional roofing system has stood the test of time for many decades. Also known as built-up roofing (BUR), tar and gravel roofing has been a popular choice for flat or low-sloping roofs in both residential and commercial buildings. In this article, we will explore the benefits, installation process, and maintenance requirements of tar and gravel roofing.
Built to Last:
Tar and gravel roofing offers exceptional durability. The installation process involves multiple layers of materials that work together to create a strong and long-lasting roof. It typically consists of three main layers: a base layer of insulation or fiberboard, a layer of bitumen (tar), and a top layer of gravel or mineral granules. This composition provides excellent protection against various weather conditions, including UV radiation, rain, hail, and high winds.
Additionally, the gravel or mineral granules on the top layer act as a protective barrier against foot traffic and offer fire resistance. This makes tar and gravel roofing a great choice for roofs that may be subject to heavy foot traffic or fire risk, such as rooftop decks or commercial buildings.
One of the significant advantages of tar and gravel roofing is its cost-effectiveness. Compared to other roofing materials like metal or single-ply membranes, tar and gravel roofing tends to be more affordable upfront. The materials used in this roofing system, such as tar and gravel, are readily available and relatively inexpensive. Moreover, the installation process is straightforward, which helps to reduce labor costs.
Furthermore, tar and gravel roofing requires minimal maintenance over its lifespan. Regular inspections and minor repairs can help prolong its durability and prevent potential issues. With proper care, a tar and gravel roof can last for 20 to 30 years or even longer, making it a long-term cost-effective investment.
Installation Process and Maintenance:
The installation process of tar and gravel roofing is relatively simple, but it is recommended to hire professional roofers with experience in this type of roofing system. They will start by applying insulation or fiberboard to the roof deck. Then, multiple layers of bitumen are heated and applied, followed by a layer of gravel or mineral granules.
To ensure its longevity, regular inspection and maintenance are essential for tar and gravel roofing. It is recommended to conduct inspections at least twice a year, paying attention to any cracks, blisters, or signs of damage. Also, it is crucial to keep the roof clean and clear of debris to prevent water pooling and other issues. Prompt repairs should be made if any damage is detected, such as patching holes or reapplying bitumen.
In conclusion, tar and gravel roofing has proven to be a reliable and cost-effective choice for flat or low-sloping roofs. Its durability, fire resistance, and ability to withstand harsh weather conditions make it a popular option for both residential and commercial buildings. If you are considering a roofing system that offers longevity and value for your investment, tar and gravel roofing may be the solution you need.
