What is skylight replacement?
Our skylight replacement service in Durham covers replacing tired domes and failed glass with a modern rooflight. We survey every job before fixing the price.
Older flat-roofed extensions in the North East are often due a new roof covering — the right time to upgrade the rooflight too. Many North East homes have loft rooms that benefit from larger roof windows with blackout blinds.

Planning and building rules in England
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

Can you replace only the misted glass?
Sometimes, if the frame is sound and the maker supplies replacement units. Often a complete new rooflight costs little more and performs better.
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
