Trade rooflight fitting in Thornaby-on-Tees

Glass is heavy, and bigger units get heavy fast. Fitting a rooflight in Thornaby-on-Tees means planning how it travels from the delivery vehicle to the roof without chipping an edge or straining a back. Smaller units go up by hand with two fitters. Larger ones may need a hoist, a scaffold loading bay or a crane, and we tell you at quote stage if that applies. Once it is up, the fitting follows the maker's sequence: seat, fix, seal, finish. We take on work like this across County Durham.

Fitting your rooflight, step by step

On the day, you need to be in at the start and at the end. In between, the fitters get on with it. They will want the room below cleared where possible, a parking spot if you have one, and somewhere to set the unit down safely. After checking the opening and the upstand or flashing, they fix a rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.

Planning, building control and Thornaby-on-Tees

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 agree up front who notifies it. 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.

Before you get in touch

What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around TS17 and we will come back with a quote or a survey date.

Common questions in Thornaby-on-Tees

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.

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.

What is included in the price?

The written quote lists it line by line. Typically that covers fitting labour, fixings, sealants, membrane or flashing materials, any upstand work, internal finishing if agreed, and taking away the waste. For supply and fit, the unit itself is included too. Scaffold, lifting gear and any third-party fees, where needed, are shown separately so you can see what each part of the job costs.
