Fascia, or that part of your property that your guttering is screwed too!

The fascia board is the one mounted at the point where the roof meets the outer walls of the house and is often called the ROOFLINE.

Unfortunately, not many people are familiar with these terms, so we thought you might appreciate a few words of explanation.

The descriptions uPVC, PVCu and PVCue are often used to describe PVC fascias, soffits and bargeboards. You probably know what PVC means. The “u” stands for “unplasticised”, meaning that it isn’t a pliable PVC like some kids toys etc, and the “e” stands for “expanded”. Expanded or foamed PVC produces a light, strong board that is thicker than an equivalent rigid PVC board.


The fascia board is the long, straight board that runs along the lower edge of the roof. The fascia is fixed directly to the lower ends of the roof trusses and usually does all the work of supporting the lower edge of the bottom row of tiles. The fascia board also carries all the guttering.

This is no mean feat, especially when it is raining hard. In a downpour the roof of a 3-bed semi could be washing several gallons of water per second into its gutters.


This is the board that is used on the gable end of a house. The condition of the bargeboard can often make or break the look of a house.



The boxend is a work of art, accommodating as it does the many different angles, planes and heights of the fascia, soffit and bargeboard at each corner of the house where there is a gable end.


Capping or Cappit fascia is ideal for those properties that have timber fascia in generally good condition and free from rot. the new 9mm thick uPVC  cappit fascia is fixed to the existing boards using polly pins paced at 500mm intervals. We supply and fit very high quality fascia boards manufactured by Deeplas.
