How we approach skylight repairs & leak fixes in Darlington
We handle skylight repairs & leak fixes across Durham, including Darlington. In short: leak tracing, resealing, actuator repairs and glass replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Older flat-roofed extensions in the North East are often due a new roof covering — the right time to upgrade the rooflight too. Skylight repairs & leak fixes suit rooflights that have stopped opening or started dripping.
Darlington is the main town we list in Durham; we also cover nearby Newton Aycliffe and Stockton-on-Tees.

Do you need permission in Darlington?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.
