25 Roof Leak Warning Signs (With Photos) — When to Call a Roofer for Repair

Moment #11: Cracked roof vent boot

Rubber vent boots crack from sun exposure and temperature swings. Once split, water can drip directly into attic spaces around the pipe penetration. This is one of the most cost-effective leak repairs if caught early, because the failure point is obvious and localized. If you notice dripping around a vent pipe during rain, the vent boot is often the first component to check or replace.
