PERFORM EPDM ROOF REPAIRS LIKE A PRO FOLLOWING THESE STEPS
WHAT PRODUCTS SHOULDN’T YOU USE TO DO EPDM ROOF REPAIRS?
EPDM is a synthetic rubber membrane, and it’s not compatible with asphalt-based products. So, we recommend that you don’t use any cement flashing, aluminum roof coating, or any asphalt-based product for neither repairing nor maintaining your rubber roof.
If you choose to do these repairs by yourself, please promise us that you will take all safety precautions. If not, please call our expert roofers to take care of your rubber roof.
PREPARING THE RUBBER SURFACE
The first step is to properly clean the EPDM surface that is going to get the rubber patch. Most of the time, EPDM roofs, as they age, contain a carbon film, dirt, and other oxidation on their surfaces.
So, we recommend that you wash a larger area in the rubber surface than the size of the patch you’ll apply. This step is of utmost importance since this will ensure that the patching piece sticks firmly to the EPDM sheet.
Make sure to dry the washed area by using cloths rugs to remove any trace of moisture. When doing EPDM roof repairs, it’s crucial to work on clean and dry surfaces.
TIME FOR CUTTING THE RUBBER REPAIR PATCH
We recommend that you measure the width and height of the rubber hole. Once you have a rectangle or a square figure of the dimensions of the hole in the rubber sheet, we recommend you to increment 2’’ to the original side lengths. You must do this so that the patch you cut extends past the area where the repair is needed.
Then, cut the roof patch carefully to fit in the rubber orifice perfectly. Make sure to cut or round the patch corners to avoid any lifted or sharp corners due to foot traffic. You should do this as a precaution measure to ensure the excellent performance of the patch.
PRIME THE ROOF REPAIR AREA
The next step for doing excellent EPDM roof repairs is to apply a thin coat of primer to the rubber membrane. Remember that you should buy a rubber primer so that you can join the two EPDM pieces the right way. Also, you should spread the primer around 3’’ beyond the edges where the patch is going to be installed.
INSTALLING THE ROOF PATCH
There are two types of rubber repair materials: pressure and non-pressure sensitive. Both materials are great options for you to perform high-quality EPDM roof repairs.
4.A) PRESSURE SENSITIVE RUBBER PATCH
The first thing to do, obviously, is to remove the thin paper or film that is protecting the patch glue. Then, you should apply the patch to the rubber sheet surface and press firmly so that the patching piece gets into place.
We recommend that you use a steel roller to apply even pressure over the EPDM roof patch. Roll back and forth to lay the patch evenly and remove any bubble of trapped air out the repair rubber patch.
Last but not least, you should apply a droplet of EPDM lap sealant around the edge of the patch. By doing this, you’ll waterproof your rubber roof.
Once you apply the sealant, you must feather it for its proper adhesion. By following these steps, you’ll become an expert in EPDM roof repairs. But remember to stay safe while performing any DIY project.
4.B) NON-PRESSURE SENSITIVE RUBBER PATCH
Well for this one, you should use a single-ply EPDM adhesive to join the rubber patch to the rubber roof. Remember that you should buy rubber-to-rubber glue so that the patching piece can be stick firmly.
Apply the rubber-to-rubber adhesive to the underside of the patching piece and over the surface of the area to be patched. Let the adhesive to dry until it is not sticky to the touch.
Then, you should proceed to carefully place the rubber patch on the surface of the EPDM roof.
Use the steel roller to apply pressure to the patch. Also, remember to waterproof the rubber patch by applying a bead of EPDM lap sealant.
