Rooflight installers in Durham

Whatever the job in Durham, the route to a price is the same. Fit-only work is usually priced from your photos and measurements. Supply and fit, replacements and new openings get a free survey. After that, a written quote sets out the scope and the price before anything is booked. The range covers rooflights, lanterns, pitched roof windows, conservation units, upstands and kerbs, and trade fitting across County Durham. Leak investigation is available too, as a charged visit with its price confirmed before you book.

Why the fitting matters as much as the unit

Product warranties on rooflights usually depend on the unit being fitted to the maker's instructions. Those instructions cover upstand height, fixing centres, sealants, and how the roof covering is dressed in. Following them line by line takes familiarity with how different units go together. A specialist fitter reads the paperwork, checks the delivery and measures the opening before starting, then fits to the book. If something on site does not match, they flag it rather than improvising. That protects both the roof and the warranty.

Postcodes and places we cover

Our fitters cover all of Durham, including DH1, DH7 and DH6, and travel on to Spennymoor, Chester-le-Street and Houghton-Le-Spring on the same basis. Nobody needs to visit us, because we come to the property for surveys and fitting. Dates are offered according to fitter availability, and travel is part of the written quote rather than an extra.

Planning and building control

England's rules in short: permitted development usually covers a rooflight on a house roof provided it doesn't stick out more than 0.15 m or rise above the ridge, though a listed building always needs consent and some streets have Article 4 directions. Building regulations apply to new openings, and replacements go through building control; as we are not registered with a competent person scheme, we use a building notice and show the fee on the quote. The energy limit for rooflights in existing homes is 2.2 W/m²K, and the 2026 Approved Document L, in force from 24 March 2027, keeps that figure.

Questions about rooflight fitting in Durham

Do I need planning permission for a rooflight in Durham?

Often not. Many rooflights fall under permitted development, provided they do not project beyond the national limit and meet the other conditions that apply in England. Conservation areas, listed buildings and some flats are different and may need consent. Because the rules depend on the property, we confirm what is likely to apply at your address and point you to the planning authority where an application is needed.

What if my roof opening is the wrong size for the rooflight?

We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.

Can you remove and dispose of the old rooflight?

Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.

Will my new rooflight leak?

A correctly fitted unit should not. Leaks usually trace back to the detail around the frame: an upstand that is too low, a membrane or flashing that is not dressed properly, sealant applied to a damp surface, or water ponding against the kerb. We fit to the maker's instructions and check each of those points. The fitting carries a written workmanship guarantee, with its terms set out on your quote.
