So your roof is leaking, and you’re hoping to avoid it with some simple do-it-yourself repairs. And if you have a new roof, knowing how to fix roof shingles is useful because cracks are frequent before the entire roof needs to be replaced. In situations like this, a homeowner with the right equipment and a handyman’s intuition can be able to fix a leak and avoid paying for skilled roofers. Small leaks caused by localised damage, such as damaged or missing shingles, are typically fairly simple to repair. In reality, finding the leak is the most challenging part of fixing roof shingles. Single-ply roofs are the easiest to repair after the leak has been discovered. this post
Examine the area of the roof that is leaking for signs of damage. A leak could be caused by damaged, misshaped, curled, or missing shingles. Make sure there are no cracks or holes in the shingles, caulking, or flashing where two surfaces meet on your roof. Once you’ve discovered the cause of the leak, there are a few options for fixing it. If shingles have rolled up, for example, you can use asphalt roof cement or compound caulking to reattach them. You should be able to quickly straighten the shingles if the weather is mild, but shingles become more brittle in cold weather and should be softened before changing them. To soften the shingle, carefully run a propane torch with a flame-spreader nozzle over it. Shingles can then be reattached to the roof by applying a generous amount of roof cement to each corner and pressing it tightly against the roof.
Shingles that are torn, broken, or rotting should be replaced. Start by raising the edges of the old shingle and using a nail puller or pry bar to remove the nails. Slide the shingle off the roof, being cautious not to leave any dried-on roof cement behind. And if your shingles get torn off during a hurricane, you’ll need to remove any remaining nails. The new shingle can then be slipped under the existing shingles and aligned with the surrounding shingles. At each of the shingle’s top corners, galvanised roofing nails should be used to secure the new shingle. Then, using roof cement, cover the nail heads and the top of the shingle with the overlapping, original shingles. You can use a little more roof cement to join the old and new shingles.
