Spark Arrestor Installation in League City, TX

A missing or rusted-through cap, torn or missing screen, embers landing on the roof, or animals and debris getting into the flue. Homes near trees, dry brush, or wildfire-prone terrain, and anyone burning wood, have the most to gain from a working arrestor on every flue.

Under NFPA 211, the spark-arrestor screen must be corrosion-resistant material with openings no smaller than 3/8 inch and no larger than 1/2 inch. The 3/8-inch minimum keeps the screen from clogging with soot and choking draft; the 1/2-inch maximum stops embers from escaping. Some areas have stricter wildfire rules, so the local requirement governs if it's tighter.

Burning embers can leave the flue and ignite the roof or surrounding brush, and the open flue takes in rain, debris, and animals. It's an inexpensive part that prevents a roof or wildland fire plus the water damage and blockages an open flue invites.

Bolt-on and clamp-on caps exist, but the work is at the flue top on the roof, the mesh has to fall within the code size range, and the cap must seal to the tile or pipe and stay put in wind. A loose or wrong-size cap fails on both fire and weather, so the fit and mesh need verifying.

Yes. A properly fitted arrestor cap doubles as an animal and rain guard, blocking birds, squirrels, and raccoons from nesting in the flue while still venting. That prevents both blockages and the fire hazard a dry nest creates inside the flue.
