Chimney Roof Flashing & Penetration Components
When installing a wood stove chimney system, the components that pass through the roof are some of the most important for both safety and weather protection. Proper flashing and roof penetration parts prevent water intrusion, maintain required clearances from combustible materials, and help stabilize the chimney as it exits the structure.
This collection includes chimney flashing and roof penetration components designed for All-Fuel HT chimney systems. Each product is available in both 6-inch and 8-inch chimney pipe sizes, making them compatible with many residential wood stove and chimney installations.
Below is an overview of the essential chimney roof components included in this collection.
Storm Collars for Chimney Pipe Flashing
Storm collars create a watertight seal around the chimney pipe directly above the roof flashing. Once installed and sealed with high-temperature silicone, the storm collar prevents rain and snow from running down the chimney pipe and entering the flashing opening.
Storm collars are a small but critical component that works together with roof flashing to protect the roof penetration and prevent leaks over time.
Roof Radiation Shields (Galvanized Firestop)
Roof radiation shields help maintain proper clearances between the chimney pipe and combustible materials as the chimney passes through the roof and attic space. These galvanized components act as a firestop, protecting surrounding framing and insulation from excessive heat produced by the chimney system.
Radiation shields are commonly required as part of a safe chimney installation and help ensure the system meets building code clearance requirements.
Ventilated Roof Flashing – Flat Roof
Ventilated roof flashing designed for flat roofs creates a secure and weatherproof seal where the chimney pipe exits the roof surface. The flashing base integrates with roofing materials while the ventilated cone allows the chimney pipe to pass safely through the roof structure.
Flat roof flashing components are ideal for homes, cabins, and structures with low-slope roofing systems.
Ventilated Roof Flashing for 12/12 Pitch (Steep Roofs)
Steep-slope roof flashing is designed specifically for roofs with a 12/12 pitch, allowing the chimney pipe to exit the roof at the correct angle while maintaining a watertight seal. The angled flashing base fits securely against steep roofing surfaces to prevent leaks and ensure proper chimney alignment.
These flashing components are commonly used in homes with steep rooflines where standard flashing would not provide the correct fit.
Ventilated Roof Flashing for Standard Roof Pitches
For homes with standard roof slopes, ventilated roof flashing designed for 0/12 to 6/12 pitch roofs provides a secure and weather-resistant chimney penetration. These flashing kits accommodate common residential roof angles while maintaining proper chimney clearance and support.
Properly installed flashing for standard roof pitches ensures reliable weather protection and long-term chimney performance.
Flashing & Roof Components FAQs
Chimney flashing creates a watertight seal where the chimney pipe passes through the roof. It directs rain and snow away from the roof penetration to help prevent leaks, water damage, and deterioration of roofing materials.
Yes. A storm collar is installed directly above the flashing and wraps around the chimney pipe. When sealed with high-temperature silicone, it prevents water from running down the chimney pipe and entering the flashing opening.
A roof radiation shield is a safety component that maintains the required clearance between the chimney pipe and combustible materials such as wood framing or insulation. It helps protect the surrounding structure from heat produced by the chimney system.
The correct flashing depends on two main factors: the diameter of your chimney pipe and the pitch of your roof. Most residential wood stove systems use either 6-inch or 8-inch chimney pipe. Roof flashing is typically designed for flat roofs, standard pitch roofs, or steep roof pitches.
Yes. Any chimney system that exits through the roof requires flashing to create a weatherproof seal. Proper flashing installation helps prevent leaks and protects the roof structure around the chimney penetration.
