The answer to 'missing shingles' is that missing shingles are a common roofing problem that can be caused by a variety of factors, including severe weather, improper installation, or simply age and wear. Symptoms of missing shingles include visible gaps in the roof, leaks, and potential damage to the underlying roof structure.
In many cases, missing shingles can be repaired by a homeowner as a DIY project, especially if it's just a few shingles. However, for more extensive damage or if the roof is older, it's best to call in a professional roofing technician to assess the situation and make the necessary repairs. A professional can ensure the roof is properly sealed and protected to prevent further issues down the line.
