The answer to 'why is my architectural shingles missing shingles' is that missing shingles on an architectural roof can be caused by a few common issues. This could be due to improper installation, weather damage, or natural wear and tear over time. Symptoms may include visible gaps or bare spots where shingles are missing, which can lead to leaks and further roof damage if not addressed.
In many cases, missing shingles can be replaced as a DIY project if the damage is limited. However, if the problem is more widespread or the roof is older, it's best to have a professional roofing contractor inspect and repair the roof to ensure proper sealing and prevent future issues.
