Steps To Repair A Tear In The Felt On A Garage Roof

If the felt on your garage's flat roof is torn, learn how to patch it with the following steps. The repaired area will prevent leaks until you are able to have the felt replaced by a professional roofer like Cloise & Mike Construction Inc.

Use The Following Materials

  • ladder
  • broom
  • scrub brush
  • soapy water
  • water hose
  • towels
  • safety goggles
  • propane torch
  • replacement felt
  • utility knife
  • measuring tape
  • roofing cement
  • paintbrush
  • roofing nails
  • nail gun

Clean The Damaged Area And Wait For It To Dry

Set up a ladder next to the garage on a day that it is not predicted to rain. Remove sticks and large debris that is on the roof by hand or with a broom. Use soapy water and a scrub brush to remove dirt that is in and around the torn area. Rinse the roofing felt off with a water hose. Press a towel against the roofing felt to soak up any excess water. Wait for the felt to dry completely.

If you would like to shorten the drying process, use a propane torch to dry the roofing felt. Wear safety glasses while doing this to protect your eyes from the torch's flame. Move the torch back and forth over the roofing felt. Hold the torch several inches away from the felt and do not hold it over one area for very long so that the felt does not become singed by the flame.

Apply A Piece Of Roofing Felt Over The Tear

Measure the torn area. Cut a piece of roofing felt that is slightly longer and wider than it. Use a paintbrush to apply an even coat of roofing cement to the back of the felt and press the roofing felt down firmly over the damaged part of the roof. Wait for the cement to cure. This may take several hours and will depend upon the current temperature outside.

Use a nail gun to install roofing nails on each side of the patched area. The nails will help hold the roofing felt in place in case the cement does not hold up. Evenly coat a paintbrush with roofing cement and apply it over each roofing nail. The roofing cement will assist with holding the nails in place. In the future, carefully clean the repaired area when it becomes dirty so that the replacement piece of felt is not damaged. The replacement piece of felt will last until you are ready to have the roof repaired by a professional.
