Product Information

Full details

This guide is for builders, roofers, and homeowners undertaking new build, extension, or refurbishment projects. The B&Q Over Fascia Vents provide a continuous, cost-effective solution for roof eaves ventilation, preventing condensation and moisture damage. A key benefit is their simple installation directly onto the fascia board, allowing for clean integration with roofing felt. One potential consideration is that while they offer a slim profile, they do require sufficient fascia depth for proper fitting.
