Here you will learn common rubber roof repair techniques, and how to use our kit to fix your roof. Before you begin, make sure that you are safe while climbing and working on the roof.
Watch This video that demonstrates how to patch an outside corner:
In this video, we are using UNCURED peel and stick flashing material to patch leaking outside corner.
First we want to mention that Rubber Roof should only be repaired in ambient temperatures ABOVE 40 degrees Fahrenheit. This is very important for the quality and longevity of your repair. Second – the surface should be completely dry when performing a repair. You should not use this kit when it is raining / snowing, or if the roof surface is wet / covered with water. Third, you should always use gloves (PROVIDED IN THE KIT) and safety goggles when repairing EPDM roofs, as chemicals used in repair can be harmful.
1) Cleaning the roof surface:
Clean repair area of all loose debris. Then, remove all loose old lap sealant. It is highly recommended that you also pull off old flashing material. If you do not do this, you will have to use WIDE (12″) flashing membrane. NOTE that new flashing must completely cover old flashing by 3″ on all sides. Cleaning Roof surface with EPDM Cleaner Once you removed old flashing, sealant and all loose debris, take a cleaning rag, fold it two times, and pour EPDM Cleaner onto the rag to soak it. Quickly begin cleaning the repair surface, but applying pressure onto the rug and rubbing vigorously, to remove old glue and dirt. Add more cleaner and turn rag over as necessary. Clean an area that is at least 3-5″ wider in each direction than the patch that you will apply. Example: If you are applying a 6×9″ patch, cleaned surface area should be about 12×15 inches. The better cleaning job you do, the better repair quality will be.
2) Applying EPDM Primer:
Once repair area is cleaned, take a paint brush and Apply EPDM Primer (thick coat) and let dry, until it becomes TACKY.
3) Applying Peel and Stick Patch:
4) Patching Corners:
6) Working with 12″ Peel and Stick Tape:
Video tutorial sequence: First, surface was cleaned with EPDM Cleaner, and Primer was applied with a paint brush extending beyond the surface of the patch. Once primer becomes tacky (dries out does not stick to your finger), the patch can be installed. Next, the patch was applied to the vertical surfaces of the corner. Once applied, the horizontal part was stretched to fit on the bottom surface. Finally, once patch was installed, a silicone roller was used to roll out any small air bubbles, and ensure bond bond with roof surface. After rolling in the patch, Lap Sealant was applied around the patch.
