Tar and gravel roofs are the most common original roofing material. A tar and gravel roof consists of layers of asphalt and tar paper. On the top is sprinkled gravel which gets embedded in the hot asphalt while others remain loose on the top of the material.
The purpose of the loose gravel is to shield the asphalt from the elements such as exposure from the sun. The life expectancy of a tar and gravel roof is about 20 years. This isn't the longest compared to other roofing systems but 20 years is still a long time and it does a great job while serving its purpose.

Tar and gravel roofs don't work all that great when applied in multiple layers. In order for this to be done right without compromising the existing structure, all layers must be stripped of the existing roofing materials. In essence you need to start over from scratch.
That is the best possible way to reduce any damage to old layers. As you can see this can mean a messy and drawn out process.

Tar & Gravel roofs have been around for centuries.

Their use has decreased with the more effective modern materials. Contact GVRD Roofing to discuss your Tar & Gravel Roof Repair today!
