The answer to 'why is my gutters missing shingles' is that missing shingles on the gutters is a common roofing issue often caused by poor installation, age, or weather damage. When shingles come loose or fall off the gutters, it can lead to leaks, water damage, and other roofing problems.
Some common causes of missing gutter shingles include: high winds or severe storms that blow shingles off, improper installation where the shingles weren't properly secured, or old age and wear and tear on the shingles over time. Symptoms include visible gaps or holes in the gutters where shingles are missing, as well as potential leaks or water damage around the gutters.
