Velux roof windows are one of the most common additions to Harrogate's Victorian, Edwardian and 1930s housing stock, where loft conversion has been a popular way to add bedroom or office space without extending the building's footprint. On the large semi-detached and detached properties of Harlow Hill, the Duchy Estate and Rossett Green, loft conversions with Velux windows have been carried out across the last 40 years — and the first generation of these installations are now needing window replacement, flashing kit renewal, or sealing repairs.
Fitting a Velux window into an existing roof requires correct specification of the flashing kit for the roof covering type — Welsh slate, clay tile, concrete interlocking — and precise cutting of the aperture. Incorrect installation is the primary cause of Velux-related leaks: undersized or incorrectly positioned flashing kits that allow water to track between the frame and the surrounding roofing material. We fit Velux windows and their associated flashings to Velux's own installation standards.
For replacement of failed or damaged Velux units, we match the existing aperture size where possible. Where units have failed due to condensation in the double-glazed panel, hinge mechanism failure, or damaged frames rather than flashing problems, a like-for-like replacement is typically the most straightforward solution.

Scaffold, Skips & Street Access
Roof window work is usually done from inside plus a roof ladder or tower; scaffold is used where the pitch or height needs safe standing time. Scaffold is specified for: installations on steep or high roofs, or dormer work requiring external standing time - always itemised in your written quote, never a hidden extra, and we arrange it.
Harrogate mixes tall three-storey Victorian townhouses on the Duchy Estate with terraced streets in Starbeck and New Park where kerbside space is tight. Pavement scaffold and skip permits go through North Yorkshire Council; allow a few working days on streets like Cold Bath Road, the terraced streets off Kings Road, Cornwall Road where space is tight.
