How to Repair a Tar and Gravel Roof

Tar and gravel roof is a common flat roofing system used by people. This type of roof contains layers of tar and roofing felt. When the final layer of hot tar is installed, gravel is applied to the coat to protect the roof from harsh weathers. During rain, this type of roof also helps in spreading water across the surface to the edges and roof drains; however, they are prone to leaks. Blistering and water pooling are other common problem areas of this type of roof. Here’s how you can get rid of these problems:

Identify the Problem

Identifying the problem in a tar and gravel roof is very difficult. Water can travel many feet from the leakage source to where it is showing up in your house. Thus, check the entire roof; inspect the areas with missing gravels and check where tar is exposed. These are the areas that cause leakage and are responsible for cracks in the roof with small dried bubbles.

Rake and Sweep

After you have identified the problem area, pick a broom and rake away the gravel. Check for crack along the flashing and then look around for patched areas where gravels are missing. Also look for lower layers where the roof is damaged. Carefully rake gravels from the problem area and also sweep off the dust and debris. To clean the area thoroughly, use a clean cloth. Sweep away the piles of gravel accumulated near the roof drains and also inspect the metal flashing where pipes come through the roof. Look for areas where the tar that overlaps is missing or cracked. Clean the area and let it dry for repairing purposes.

Apply Primer and Patch

After you have cleaned the area and allowed it to dry well, apply the primer now. The primer helps the patches to adhere properly. To apply it effectively, use a roller or a paint brush. Apply an even coat and then allow it to dry completely. Next, you need to apply your repair patch. It is always recommended that you apply this patch in two layers. While applying the first patch, make sure that there are no trapped air pockets and then press it to your roof firmly with the help of a roller. In the same way, apply the second patch. In the end, cover your patch with an even layer of gravel.
