Velux and roof window installation and repair across Stratford-upon-Avon and Warwickshire. New installations on all tile types, flashing replacements and failed unit repairs. Free quotes, conservation advice included.
Velux window installation and repair is one of the more technically demanding single elements of domestic roofing. The interface between a roof window and the surrounding tile course is a complex waterproofing detail that must account for the specific tile profile, the roof pitch, the flashing system selected, and the thermal movement of both the window frame and the surrounding structure. A correctly installed Velux window is watertight for 25 or more years. An incorrectly flashed one is a recurring leak call.
We install Velux, Fakro and own-brand roof window units on all standard roof pitches and tile profiles across Stratford and Warwickshire. For clay plain tile roofs in Stratford's conservation area we carry the appropriate conservation flashing profiles that maintain the correct tile lay around the window opening. For listed buildings requiring planning consent before installation, we provide the technical drawings and specification that planners require.
A new Velux installation involves structural assessment of the rafter spacing, cutting the opening to size, installing trimmer rafters where required, fitting the window frame, applying the correct flashing kit for the tile profile and pitch, and re-tiling the surrounding courses. We carry the most common Velux and Fakro sizes in stock and can typically complete a single new window installation in one day.
Failed Velux flashings are the primary cause of skylight leaks and are significantly more common on Stratford properties than window unit failure. The standard integrated flashing kit must be matched to the specific tile profile — an EDZ kit on a clay plain tile roof, for example, creates a different detail than on a concrete interlocking tile. We carry a full range of Velux flashing kits and can typically repair or replace a failed flashing detail in half a day.

Free quotes — no call-out fees — honest advice.
“Failed flashing on a Velux installed about 15 years ago. They replaced it with the correct conservation profile kit for the clay tiles and re-tiled the surrounding courses perfectly. No leak since.”
“New Velux in the master bedroom — previous roofer had said the pitch was too shallow. These lads assessed it, confirmed a low-pitch kit was appropriate and installed it in one day. Excellent light in the room now.”
“Two existing Velux windows re-sealed and a new one added at the same visit. Much more cost-effective than separate call-outs. Clean, professional and all three are completely watertight.”
A single Velux or equivalent roof window installation in Stratford typically costs £600 to £1,400 including the window unit, flashing kit and labour. The price depends on the roof pitch, tile type, and whether existing structural alterations are required. For conservation area properties in Stratford where planning approval is required, we advise on the consent process before quoting. Free surveys available for all Stratford and Warwickshire properties.
Most roof light installations on non-listed properties outside conservation areas fall within permitted development rights and do not require planning permission, provided the window does not project more than 150mm above the existing roof plane and is not on the principal elevation. Properties within Stratford's Old Town conservation area and listed buildings may require consent. We advise on this in every pre-installation survey.
Velux window replacement requires removal of the surrounding tiles, replacement of the flashing kit, and careful re-tiling to ensure the new unit is correctly waterproofed at all four edges. It is not a DIY task on a standard roof. An incorrectly flashed Velux is one of the most common single-source leak calls we receive. We carry a range of Velux and compatible flashing kits for standard pitches and tile profiles.
Failed flashing is by far the most common Velux issue we repair. This typically occurs when the original installation used a standard flashing kit on a tile profile it was not designed for, or when the flashing was not correctly integrated with the surrounding tile courses. The second most common issue is handle and seal failure on older units, which causes draught and condensation rather than water ingress.
Yes, with the appropriate consent in place. For Stratford conservation area properties, Velux and equivalent roof windows may be permitted on rear elevations that are not publicly visible, subject to the planning officer's assessment. We advise on the most appropriate route for each property and can provide technical drawings for planning submissions where required.
No call-out fees. No obligation. Local roofers covering Stratford and Warwickshire since 2003.
