A roof termination changes the risk calculation.
The rental is not permission or equipment for climbing onto a roof. If the termination cannot be evaluated safely from the ground, request professional help.
Why roof vents are harder
Roof terminations may contain lint beneath the damper, bird material or a cap that is difficult to inspect. Long vertical runs can also allow loosened lint to remain in the system. Working from only one end may not verify that the line cleared.
Safer escalation
Tell us the dryer location, estimated roof height, visible termination type and symptoms. We can help determine whether a qualified provider should inspect and clean the system with appropriate access and fall protection.
