What To Know About Carbon Monoxide Risks After A Roof Replacement Or Repair

Carbon Monoxide Risks - Loose flue vent pipe

If you just had a roof replacement or repair, this is worth a quick read. Carbon monoxide risks aren’t something most homeowners think about after roof work, but they’re worth knowing about.

This photo shows a flue vent pipe that got knocked loose during a recent roof replacement. Our technician Brian caught it and reattached it right away.

To be clear, this isn’t roofing-company bashing. Most roofers do great work. It’s just that moving vent stacks on the roof can unintentionally disconnect a flue pipe, and some contractors may not realize it’s happened.

Why Roof Work Can Create Carbon Monoxide Risks

Fuel-burning systems like furnaces, water heaters, and gas stoves rely on flue pipes that vent through the roof. These pipes exist for one job: directing carbon monoxide and other combustion gases safely outside your home.

During a roof repair, replacement, or even a bad storm, these pipes can get bumped loose without anyone noticing. If a vent isn’t properly reconnected to a fuel-burning appliance, that’s when carbon monoxide risks start to climb, since the gas has nowhere safe to go.

The Numbers Worth Knowing

According to Angie’s List, accidental carbon monoxide poisoning contributes to several hundred deaths in the U.S. each year, with thousands more people ending up in emergency rooms from exposure. It’s not an everyday occurrence, but it’s common enough that a quick check after roof work is worth the few minutes it takes.

What To Do About It

Checking for this issue is simple:

– Look at the flue vent piping that runs from your gas appliances up into the attic.
– Confirm the pipes are still connected and haven’t shifted or come loose.
– If you’d rather not head into the attic yourself, or just want a second set of eyes, give us a call and we’ll take a look.
