Roof Vents for Wood Burning Fireplaces Roof Vents for Wood Burning Fireplaces
Roof vents for wood burning fireplaces typically use a masonry chimney to vent smoke and combusted air to the exterior of the home, up and out through the chimney. Properly vented wood burning fireplaces remove heated air and ash that can either harm the flue or come back into the room, producing harmful fumes.
Too often a faulty roof vent is a chimney that's too short. The vent needs to be extended at least three feet above the roof. It should be two feet taller than any other structure within a 10-foot radius on the roof. Make sure that a layer of bricking is applied to meet the minimum height requirements.

Proper venting will allow the fumes to be drawn upward and out of the structure, as well as ensuring that coals do not blow into the room causing fire danger.
Installing A Vent: Brief List
- Measure the flue opening and purchase venting material (liner) meant for high heat.
- Attach the venting material and feed to the top of the roof.
- If not already present, cut a hole for the vent in the roof.
- Attach the roof vent to the venting material and seal the roof hole to prevent leaks from the weather
A properly working chimney needs a liner that protects the surrounding area from any heat transfer that could cause an in–wall fire. Liners are typically clay or ceramic tiles or a metal conduit that directs combusted air to the outside, protecting the chimney walls.
