Troubleshooting
Reduced airflow or blockage.
Check the vent for accumulated debris such as leaves or nests. Gently clear any obstructions using a soft brush or compressed air. Ensure no roofing materials are obstructing the vent opening.
Vent appears deformed or damaged.
Inspect the vent for signs of impact or weathering. If deformed, it may need replacement to ensure proper function and pest deterrence. Contact the supplier for replacement options.
Water ingress near the vent.
Verify that the roofing felt is correctly installed over the vent and into the gutter, creating a watertight seal. Ensure fixings are not compromising the seal. Re-check felt installation if water ingress is observed.

Setup, Compatibility & Care
Setup:
- Ensure the top of the fascia board is clean and free from debris.
- Position the vent directly onto the fascia board, aligning it with the roofline.
- Secure the vent using appropriate fixings (e.g., screws or nails, not included), ensuring it is firmly attached.
- Allow the roofing felt to overlap the vent and extend cleanly into the gutter.
- For continuous runs, butt subsequent vents together tightly.
Compatibility:
