The answer to 'why is my roof missing shingles' is that there are several common causes, including severe weather, age and wear, improper installation, and poor maintenance. Shingles can become loose, cracked, or blow off entirely due to high winds, hail, or heavy rain. Older roofs that are 15-20 years old are also more prone to shingle loss as the materials deteriorate over time. Incorrect installation techniques or using low-quality materials can also lead to shingles falling off prematurely. Lack of regular roof inspections and maintenance, such as replacing worn flashing or sealing exposed nails, can accelerate shingle loss as well.
In most cases, missing shingles require prompt repair to prevent further damage to the roof deck and interior of the home. Smaller areas with just a few missing shingles may be a DIY project, but larger sections or entire roof replacements are best handled by professional roofing contractors. They have the right tools, materials, and expertise to properly diagnose the underlying issues and make long-lasting repairs.
