Check to see if the roof sheathing is water-damaged. To do this, go into your attic with a flashlight and look for water marks on the wood. If the sheathing is wet, you don't need to patch your roof. Your best bet is to call a contractor and replace the roof, along with the water-damaged sheathing.

Sweep the debris off the area of the roof to be patched. Wipe off the repair area with a wet rag and scrub with a regular household cleaner and scrub brush, then rinse with just enough water to remove the cleaner then dry the area. Clean it again with xylene. You need a clean area around the patch for the repair tape to adhere to.

Apply EPDM repair tape, which comes in 6-inch widths, centered on the roof seam to be patched, or centered over the puncture. This can be purchased at specialty roofing supply stores.

Roll the patched area with a hand roller. This is to insure the roof patch will adhere to the existing roof.
