Annual inspections

It is recommended that the roof drain system be inspected at least once annually, ideally in the spring or fall. During the inspection, check that all components are securely installed and clear of debris. Ensure drain screens and domes are securely fastened and cleared of clogs. Check for signs of water ponding or leaks around drains and repair or replace damaged components as needed.


Flexible drains require periodic cleaning to remove built-up sediment, leaves, and other debris. Clogged drains can lead to water ponding, leaks, and roof damage. Remove domes and screens and use a hose, plumber’s snake, or rodding tool to clear out drains. For tough clogs, you may need to insert an auger or “plumber’s friend” tool. Once cleared, reinstall domes and screens.


In colder climates where temperatures drop below freezing, flexible drains must be properly winterized to avoid ice dams and damage. Disconnect hoses and extensions, and install winter caps or plugs over drain outlets. Domes and screens alone may not provide adequate protection from ice and snow. Check that all components are securely installed before the first freeze.

Damage repairs

Inspect flexible drains regularly for signs of damage like cracks, holes, or tearing, especially in areas where components connect or bend. Have any damage repaired or components replaced immediately to avoid leaks and ensure proper function. Flexible drains are durable but not indestructible, so repairs or full replacement may eventually be needed for older systems.

Following these best practices for maintaining your flexible roof drain system will help maximize its performance, extend its lifespan, and avoid costly damage to your roof. Conducting routine inspections and cleaning, properly winterizing the system, and repairing any damage right away are the keys to keeping your drains flowing freely.
