Frequently Asked Questions

1. What is the purpose of an unvented soffit board?

Unvented soffit boards are used to seal off the underside of the roof overhang, protecting the rafters from the elements and improving the appearance of the roofline. They’re ideal when roof ventilation is handled elsewhere in the structure.

2. Is the Floplast soffit board suitable for DIY installation?

Absolutely! The board is simple to cut and fit using basic tools. It’s designed to be user-friendly, making it a great option for DIY projects as well as professional installations.

3. Will the board fade, crack, or discolour over time?

Not at all. The high-gloss PVC surface is UV-resistant and weatherproof, meaning it retains its colour and shape over the years with very little maintenance.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
