Velux roof window supply, installation and flashing across St Thomas. We install on Welsh slate, concrete tile and clay tile with the correct Velux flashing kit for each roof type. High slate density and conservation area proximity — we advise on prior notification requirement before every St Thomas Velux installation. Free survey. Call 01392 759 295.
Velux window performance depends as much on the correct flashing specification as on the window itself. A standard EDW flashing kit suits most concrete and clay tile roofs in St Thomas. For Welsh slate, low-pitch roofs and heritage properties in St Thomas’s conservation areas, specialist flashings are required. We specify the correct flashing type at the survey stage — not after the window has been ordered.
Most domestic Velux installations in St Thomas are permitted development. The exceptions are properties in the conservation area, listed buildings, and installations that would exceed the permitted development limits for roof alterations. We confirm the planning position for every St Thomas survey before the window is ordered. High slate density and conservation area proximity — we advise on prior notification requirement before every St Thomas Velux installation.
A standard Velux installation in St Thomas follows a clear sequence: survey confirms size, model and flashing type; window and flashings ordered; installation day — tiles removed, counter-batten and tiling batten adjusted, Velux EDL or EDW flashing fitted, window seated, tiles reinstated, internal reveal finished. The roof is weather-tight by the end of the same day. We carry a range of standard Velux sizes on all vehicles so most St Thomas surveys result in same-week installation.
