Roofer in Gorseinon, undefined

Gorseinon has an unusually consistent roofscape: rows of inter-war and post-war housing on fairly level ground, which means the problems here are predictable and mostly to do with age rather than exposure.

A twentieth-century town

Gorseinon lies north-west of Swansea in SA4, close to the M4 at junction 47, and grew around the steel and tinplate works at Bryngwyn.

Most of its housing dates from between the 1920s and the 1970s, so concrete tile and early interlocking tile roofs are the norm rather than natural slate.

The ground is comparatively level and the town is sheltered from the worst of the coastal wind by the higher land towards Penllergaer and Loughor.

Age-related, not weather-related

Concrete tiles from the mid-century laid on now-perished felt are the standard Gorseinon roof, and the felt fails long before the tiles do.
Original timber fascias and soffits on this housing are at the end of their painted life, which is why roofline replacement is such common work here.
Ridge mortar from the original build is typically overdue for re-bedding or dry fixing.

My tiles look fine but the roof leaks at the edges. What is happening?

Almost certainly perished sarking felt at the eaves. Water gets past the tiles normally, but with no felt to guide it into the gutter it runs behind and rots the fascia.

Is replacing fascias and soffits worth doing on its own?

Yes, if the covering is sound. It is a separate job from re-roofing and it protects the rafter ends and gets the gutter running properly again.

Which areas around Gorseinon do you cover?

Loughor, Gowerton, Penllergaer, Waunarlwydd, Pontarddulais, Grovesend and Penyrheol.

In Gorseinon the tiles usually outlive everything underneath and around them, and that is what needs the attention.
