What is a common cause of leaks in roofs?

A common cause of leaks in roofs is damaged or missing shingles. Shingles serve as the first line of defense against weather elements, including rain and snow. When shingles are compromised due to age, severe weather, or improper installation, they can crack, curl, or entirely detach, creating openings through which water can penetrate. This can lead to significant water damage inside the structure, including mold growth, rot, and compromised structural integrity.

Other potential causes, while they may lead to problems with drainage or overall insulation of the home, do not directly create vulnerabilities in the same way that damaged or missing shingles do. Excessive snow accumulation could contribute to leaks, but it is the impairment of the shingles that ultimately allows that snow melt or rain to infiltrate. Similarly, poor insulation and clogged gutters can lead to other types of moisture-related issues, but they are not the primary contributors to roof leaks as damaged or missing shingles are.
