Learn How To Patch A Torn Section Of Roofing Felt On A Flat Roof

If your home has a flat roof and one of the sections of roofing felt is torn, leaking may occur inside of your home. Learn how to patch the torn area with the following steps to stop the leak and preserve the roofing felt.

Use The Following Materials

  • ladder
  • towels
  • broom
  • scrub brush 
  • mild detergent
  • cloths
  • safety goggles
  • propane torch
  • roofing cement
  • paintbrush
  • putty knife
  • roofing nails
  • nail gun
  • water hose

Inspect The Roof And Dry The Felt

Set up a ladder next to the section of the roof that is leaking. Inspect the roofing felt for tears. Once you find the area that is causing the leak, wipe up any water that has pooled on the roof's surface with a towel. Use a soapy scrub brush to clean surface stains from the felt. Remove the soapy residue with a damp cloth. Wait for the roofing felt to dry completely before making the repairs.

If it isn't sunny out or if the temperature is cool, you can speed up the drying process with a propane torch. Only use a torch if you are experienced with using one. Put on a pair of safety goggles and aim the nozzle on the torch towards the roofing felt. Move the torch back and forth for a few minutes. Do not let the flame hit one section of the roof for too long. This could cause the roofing materials to melt.

Patch The Tear In The Felt

Patch the tear in the felt with roofing cement on a day that is not supposed to rain. Add the cement to a paintbrush and apply it evenly across the tear. If too much cement is added in one section, smooth it out with a putty knife. The cement will take several hours to dry. After this has occurred, use a nail gun to install roofing nails along both sides of the repaired area. Space the nails out evenly. Use a paintbrush to apply a coat of roofing cement over the nail heads. The roofing nails will assist with keeping the roofing felt secured to the roof.

Maintain The Roof

Keep the roof clean throughout the year by spraying it off with a water hose. Inspect the surface for damage after severe storms. If any additional tears or cracks are found in the roofing felt, repair them right away to minimize the risk of them becoming larger. These steps will help the roofing materials last for many years.
