How we approach skylight repairs & leak fixes in Hertford
We handle skylight repairs & leak fixes across Hertfordshire, including Hertford. In short: leak tracing, resealing, actuator repairs and glass replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Think of skylight repairs & leak fixes for rooflights that have stopped opening or started dripping.
We work across Hertfordshire, including Hertford, and in neighbouring towns such as Hoddesdon and Welwyn Garden City. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose

Consents for skylight repairs & leak fixes in Hertford
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.

Common questions
Why is my skylight leaking?
Common causes are a failed seal, a membrane that has split or lifted at the upstand, a low upstand, blocked drainage or condensation mistaken for a leak.
Can you repair an electric rooflight that will not open?
Often, yes — actuators, controllers and rain sensors can be replaced if parts are available.
Do you repair roof windows too?
Yes — flashings, seals, hinges and glass on pitched roof windows.
