4 Tips For Repairing A Rubber Roof

Posted on

If you have a rubber roof installed on your home, you are in luck, because the repairs and maintenance tend to be easier on this material than other types of roofing. If you have a leak or other source of damage, these tips will help you get the rubber roof repaired.

Use the Right Products

One of the most important things to know about repairing a rubber roof is what products you can and can't use on this type of roofing material. Rubber roofs are made of synthetic rubber membranes, which means you should not use products that are meant for asphalt. Make sure none of the products are asphalt-based, including roof coating and roof cement. They will not be effective at repairing your rubber roof. Read the label on the products thoroughly to be sure they are safe to use on rubber roofing systems, or ask someone for their assistance.

Clean the Roof

You should always start with a clean roof whenever you are going to make repairs. Mild cleaning products are best on rubber roofs since they won't leave behind a residue or destroy the surface. Similar to repairing products, choose your cleaning products carefully and ask a professional for their assistance if needed. While you really only need to wash the area of the roof where the repair is going to be done, it is a good idea to wash the entire roof. It should be cleaned regularly anyway, and this gives you the chance to get it clean.

You can use a hose if you have one that reaches the roofing surface for rinsing the roof, but be sure not to use a power washer. The pressure is too strong and can damage the roof further. If you are dealing with a leak, you will need to wash the area very carefully. To scrub the rubber roof, use cloth rags instead of a scrub brush, as they are much gentler.

Prepare the Patch

When repairing a hole or crack on a rubber roof, a patch is usually needed. Once your roof is clean and dry, you can take measurements for your patch. You want the patch to be slightly larger than the area you need to be repaired. The material should be the same material used for your roofing surface. After you have measured the patch, cut it according to your measurements. When you do so, round out the corners. Sharp corners give debris and snow a place to get caught, which can lead to other problems.

Prime and Install the Patch

At this point, you are ready to finish installing the patch. You need to add primer to the area first, as this provides a smooth surface for your patch application. Apply a thin, even coat over the area of the roof that needs to be repaired. Make sure the primer goes past the area to be patched, similar to when you measured for the patch. You can use a paintbrush or small roller to apply the primer. Once that has been applied, you can apply an adhesive for the patch.

Next, get your patch and place it on the area with the adhesive, pressing down firmly. For rubber roofing patches, it is best to use a steel roller to be sure it is even and pressed firmly in place. It is also recommended that you add a lap sealant around the patch to ensure it remains in place.
