Topic: Roofing Leaks

Sharp shingle points left in a roof valley can catch twigs and leaves, creating a dam that causes leaks during heavy rain or "gully washers." These issues often result in mystery leaks that standard repairs fail to resolve because the original installation geometry remains incorrect.

Old-style plastic roof vents show extreme signs of deterioration, including visible holes that lead directly into the attic space. While not necessarily an installation error, the age of the material has caused the seals to fail completely. These openings allow significant water penetration during rainstorms, necessitating immediate replacement to prevent structural damage.
