Fiberglass roofs are very high quality and popular because of the aesthetic appeal it adds to a home. The roof is made of very fine glass fibers that are combined with resins. Fiberglass is very easy to install and very durable, making it a prime choice for roofing. It is also a very low maintenance because it’s naturally resistant to damage. But it is not impervious to damage and you may need to repair the roof. This is when it will come in handy to learn about patching a fiberglass roof.
The first step in patching a fiberglass roof is to prepare the area that’s been damaged. You will need a ladder to get to your roof and be sure that you can safely get to the damaged area of the roof. Whether the damage is an actual hole in the roof or just a worn down area you need to make sure to remove all loose material from the area. This will make the roof surface smoother and let the repair material adhere to it more easily. The best method to clear out the loose debris is to brush it away with a stiff-bristled brush.
Now in your journey of patching a fiberglass roof, you are ready to clean the area. Use a clean cloth and acetone to wipe the damaged fiberglass. This will make sure that when you start patching that you have a clean surface to work with.
The third step in patching a fiberglass roof is to sandpaper the area around the damage. Use a 200-grit sandpaper to get the best results. Be sure to sand at least 1-inch in all directions from the damaged area so that when you start you will make sure it is that much smoother to patch a fiberglass roof.
Using your kit for patching a fiberglass roof you will need to cut out a round patch to fit the area. Be sure that the patch is big enough to extend 3 inches around the damage in all directions.
Your fifth step to patching a fiberglass roof is to apply a sealant all around the damaged area. Using a plastic scrapper to apply it around the edge of the patch itself as well, you can then switch to a feathering tool to spread the sealant to cover the entire patch.
Now you are ready to place the patch over the damaged area. Be sure to press it firmly so that it bonds to the roof correctly. This is one of the most important steps in patching a fiberglass roof. Smooth the patch with your feathering tool so that there is a complete seal, with no air bubbles or leaks. Allow it to dry completely before doing anything else.
Once the sealant is dry you need to sandpaper the edges of the repaired area. Sand it down until it matches the appearance of the rest of the rood. Clean with acetone and a rag before you do the final step.
The final step in patching a fiberglass roof is to apply a gel coat to the repair. Wait for the gel coat to harden and then add a second coat. This ensures that the repair will last a long time and not cause any further problems.
