You can repair the blown-off shingles if they aren’t broken into fragments. Cracks can be addressed using a roofing sealer. You can remove the shingle from the roof for an effective repair. That is necessary because you’ll have to cover the crack on both sides. If you can access the underside of the damaged shingles while on the roof, then you don’t have to remove them from the roof.
Fixing a crack is something you can do by yourself. But that depends on the level of damage. Some cracks require a pro to fix. For better results, patching should be done on clean surfaces. Shingles gather dust and granules that can hinder sealant from sticking to the surface.
Be sure to scrape off dust build ups from the shingles you want to repair. You can wash them using a mop and soapy water. Allow the shingles to dry. Next, knead the sealant into thick blobs and cover the crack on both sides of the shingle. Use a putty knife to spread the sealant.
Besides roof sealant, you can also use roofing cement or adhesive. It’s that simple, but minor repairs can keep your roof functional and able to withstand the elements for many years.
