Recently Tilehurst Roofing Contractors were called to attend a property in Tilehurst which had lost its fascia and barge boards in recent high winds. On attending the site, we spotted that a new u.p.v.c Cappit system had been pinned onto rotten timber fascia.
The gutter was screwed into the Cappit system. Just the slight wind had lifted the fascia and guttering causing it to fall.
A Cappit system is a u.p.v.c flat board fascia designed to fit over strong and sound timber and have raised areas to the rear of the fascia to allow for proper air flow to prevent dampness building up. And these systems are good if used correctly.
We suggest if you are going to use a Cappit system, the existing fascia or barge boards are cleaned down and inspected first, and any rotten timber replaced and spliced in and made good. To this new wood, we would then always apply 2 coats of primer and undercoat to maximise protection against the elements.
Usually the only time we use a Cappit system is to cover large barge board details, which are usually flying rafters and supporting the ridge bar, purlins and wall plates. Its usually best to replace structural fascia with new u.p.v.c Jumbo or 18mm solid fascia boards.
Always check that no rot is being covered over before fitting any Cappit system.
