4 Tips For Repairing A Hole On A Flat Asphalt Roof

Posted on

Flat asphalt roofs are very common with residential and commercial buildings.. They are easy to maintain and repairs are simplified since you can walk across the roof with ease. However, wear and tear does occur with these roofs, just like any other roofing style or material. Here are some tips for repairing your flat asphalt roof.

Collect Your Tools and Materials

If you are accustomed to completing DIY projects, you might already have many of the supplies you need. Others can be purchased at your local hardware store. To repair your flat asphalt roof, you will need the following items on hand:

  • Pry bar
  • Trowel
  • Caulk gun
  • Dust brush
  • Scissors
  • Utility knife
  • Roof cement
  • Asphalt primer
  • Reinforcing fabric
  • Ladder

Clean and Prepare the Roof

Once you have collected all the tools and materials you need for the repair job, it is time to start preparing your roof. It will first need to be cleaned so that the patch has a smooth surface to adhere to. If you have gravel on your roof membrane, this can be a little more difficult. In this case, you will need to remove the gravel first, since the patch material won't stick to the loose gravel.

You can use your pry bar to scrape off the gravel from the surface of the roof. Use it in only one direction and don't drag it back and forth in opposite directions. Only use as much pressure as you need to remove the gravel, otherwise you risk damaging the roof even more. Once the gravel has been removed, you can clean the roof with your dust brush. This will get rid of debris and dirt. You don't need to wash the roof with soap and water; you are simply removing dirt and debris to provide a clean and smooth surface for the repair materials to attach to.

Add the Primer and Prepare the Fabric Patch

When the roof is completely clean, the next step is to add a liquid primer to the roof surface that needs to be repaired. This can be applied with a paint roller or paintbrush. If you have an older roof that doesn't have many natural oils, the patching material won't stick to the roof. This is where the liquid primer comes in. It provides a slightly wet surface for the patching material to stick to. After applying the primer, cut a piece of fabric patch that is slightly larger than the damaged area. Cut another piece slightly larger than the first.

Finish the Repair Job

To patch up the hole, you will need your cement and the fabric patches. Add some of your asphalt cement to the surface of the roof where it needs repairs, then place the smaller of the two fabric patches over the wet cement. Use your trowel to imbed the fabric into the cement. Repeat this process with more cement and the larger piece of fabric patch. Add a coat of asphalt mastic over the second of the fabric patches to complete the repair. You can now add more gravel if you needed to remove it to make the repair.
