This Ubbink Over Fascia Vent is an essential roofing component for professional contractors and serious DIYers looking to ensure effective roof space ventilation. It delivers a substantial 25,000mm² of airflow per metre, helping to prevent moisture buildup and condensation within the roof structure. While it provides excellent performance and protection, it requires precise installation at the fascia board level before the roofing felt is secured, meaning it is best suited for new installations or complete re-roofing projects.

Yes, this vent is compatible with all types of tile and slate roofing.
The pack contains 10 units; please check individual unit length to determine total linear coverage for your roof.
Nails are not typically included; please use suitable corrosion-resistant roofing nails for installation.
No, this product is specifically designed for the fascia boards of pitched roofs.
The mesh is designed to keep pests out while allowing air passage, but it should be checked for debris during annual gutter maintenance.
This product provides a 25mm equivalent air gap.
Check that the roofing felt is not pulled too tightly over the vent, which may compress the air gap.
Ensure all fascia boards are installed in a perfectly straight line and that the vent ends are butted together without overlap.
To install, ensure your fascia boards are level and securely fixed. Position the vent along the top edge of the fascia, ensuring it is flush. Use appropriate corrosion-resistant nails to secure the vent to the fascia. Once the vents are in place, the roofing felt must be dressed over the top of the vent to ensure water drains correctly into the gutter while air can still pass through the mesh into the roof void. For maintenance, little is required; however, it is good practice to visually inspect the gutter line during routine gutter cleaning to ensure the insect mesh remains clear of debris or blockages that could restrict airflow.
