Stove Pipe Roof Flashing Types & Costs (Complete Guide)

When it comes to safely venting wood stoves or fireplaces through your roofing, stove pipe roof flashing plays a crucial role. This specialized flashing is designed to seal the area where the stove pipe exits the roof, preventing water leaks and protecting your home from moisture damage. There are several types of stove pipe roof flashing available, each suited for different roofing materials, pipe angles, and environmental conditions. Whether you’re working with metal, Asphalt shingles, or tile roofs, choosing the right flashing type ensures durability, weather resistance, and fire safety. In this guide, we’ll explore the most common stove pipe roof flashing types and help you determine which one is best for your Installation.

What is Stove Pipe Roof Flashing?

Stove pipe roof flashing is a type of flashing designed specifically to cover stove pipes or vent pipes exiting through roofs, to protect them against water seepage at their points of penetration, to stop leaks occurring there and cause structural damages over time. Without this protection in place, water may penetrate roof systems causing leakage which then seeps inside to the roofing material itself and lead to mold growth, leading to further structural damages over time.

Roof penetrations are one of the primary sources of leakage, and stove pipes are no exception. Stove pipe roof flashing provides a waterproof seal between the pipe and roofing material by way of installing it with a base flange secured to roof deck and an outer cone/collar that directs water away from its joint.

Flashing units are widely utilized when venting wood-burning stoves and pellet stoves through roof venting systems. Since stove pipes tend to carry high temperatures – especially wood stoves – flashing materials must be heat resistant and weatherproof in order to provide proper roof ventilation.
