Tar and gravel roofs are durable and ideal for flat or low-slope structures. They are made from layers of asphalt and roofing felt topped with gravel. The gravel protects the roof from UV rays and weather damage. This type of roof offers good insulation and energy efficiency. It's commonly used on commercial buildings and older homes. Regular maintenance helps prevent leaks and extend its lifespan. With proper care, they can last up to 30 years or more. Tar and gravel roofs are a cost-effective and reliable option.
