The answer to 'why is my roof decking missing shingles' is that there are several common causes, including severe weather, improper installation, and general wear and tear over time. Missing shingles can expose the roof decking, which is the underlying structure that supports the shingles. This can lead to further damage if not addressed promptly.
Some key symptoms of missing shingles include visible gaps or holes in the roof, water leaks, and potential damage to the home's interior. Solutions may involve repairing or replacing the missing shingles, or in more severe cases, replacing the entire roof. While some minor shingle repairs can be a DIY project, it's generally recommended to call in a professional roofing contractor, especially for larger issues or if the roof is older and more complex.
