Doing a basic wall repair like this can save you a lot of money, and is very easy to do. This is a standard method of repair and can be used on built-up or SBS modified bitumen systems.
Step 1:
Make sure the area is clean from dirt and other debris. If necessary scrape old roofing material off.
Step 2:
Apply a thin layer of wet patch to the area to be repaired approximately 1/8 thickness (make sure to apply wet patch at least 2 to 3 inches wide around the entire area of repair).
Step 3:
Place the reinforcement webbing. Center the webbing with the split.
Step 4:
Apply another thin layer of wet patch on top of the reinforcement webbing.
The final repair should look like this. You can apply some aluminum roof coating over the top if you wish, but its not necessary.
The above pictures are for illustration purposes for a typical 3 course repair only. This type of repair is used on built-up or SBS modified bitumen systems. Or also known as “rolled roofing”.
