The Ubbink Over Fascia Vent is an essential roofing accessory for contractors and DIY homeowners seeking to maintain proper roof ventilation. It offers an efficient 10,000mm² airflow per meter through a 10mm air gap, ensuring effective moisture management and protecting roof structures from condensation. While it is highly versatile and fits most roof types, it is specifically recommended for roofs with a pitch of 30 degrees or greater, requiring careful planning for shallower roof designs.

No, this product is specifically engineered for pitched roofs, with a recommended minimum pitch of 30 degrees.
The pack includes the vents, but you will need to provide appropriate rust-resistant nails for your specific fascia material.
The mesh is integral to the design of the vent. If the mesh is damaged, the entire vent unit should be replaced.
Each unit is typically 1 meter in length, so one pack of 5 covers 5 linear meters of eaves.
It is designed for standard tiles and slates; please consult a roofing professional to ensure compatibility with specific metal profile systems.
Using this on roofs below 30 degrees may reduce the efficiency of the airflow; check building regulations or manufacturer guidance for specific low-pitch alternatives.
Check the exterior of the vent for buildup of moss, dirt, or leaf debris and clear it using a soft brush.
Verify that the roof felt is positioned correctly over the vent flap to direct water into the gutter.
Ensure that the correct gauge nails are being used and that they are driven flush into the timber fascia board.
To install, nail the vent strip directly onto the top edge of the timber fascia board. Ensure that the roof felt is laid over the top of the vent flap so that moisture running down the roof can drain into the gutter rather than behind the fascia. The product is compatible with slate, clay, and concrete tiles. Routine maintenance is minimal; however, it is recommended to conduct a visual inspection once a year to ensure the insect mesh remains clear of debris, such as leaves or moss, which could potentially block the airflow.
