If you have a leaky shingle roof, the first step is to find and fix the source of the leak. Once you've fixed the leak, you can then seal and waterproof the roof with a coating of asphalt emulsion.

If you have a leaky shingle roof, the best way to repair it is to replace the damaged shingles. Begin by removing the shingles that are damaged and replacing them with new ones. You can either replace the damaged shingles one at a time or replace all of the shingles on your roof at once. Once you have replaced the damaged shingles, be sure to apply roof sealant around the edges of your roof to prevent future leaks. Roof sealant can be purchased at most hardware stores.
