Roof Dryer Vent Maintenance
If your dryer vent exits through the roof, it needs more attention than a side-wall vent. Long vertical runs collect lint faster, the exit is harder to see, and a clog can go unnoticed for years.
Why roof vents need more care
Hot air rises naturally, but lint settles on horizontal sections in the attic and packs at the roof termination. Add wind-driven rain and the occasional bird nest, and you have a system that wants to clog.
Signs your roof vent needs attention
- Long dry times
- Lint visible at the roof hood
- Birds landing or perching on the hood
- Burning smell during a cycle
- Hot laundry room
Maintenance basics
- Visually check the roof hood twice a year if safely possible
- Watch for bird activity, especially in spring
- Schedule professional cleaning every 1 to 2 years
- Replace damaged or screen-only hoods with a guarded roof termination
