Rooflight installers in Kilburn

Every rooflight job in Kilburn has the same core: a correctly sized opening, an upstand or flashing that suits the roof, a unit fixed to the maker's instructions, and a weathertight seal. Around that core the work varies. Fit-only installs, replacements on existing kerbs, new openings with joist trimming, roof lanterns over extensions, roof windows in pitched roofs, and subcontract fitting for trades working in the area. We handle all of it across Greater London, with a written quote before work starts and a workmanship guarantee whose terms are on that quote.

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

Covering Kilburn properly means covering the whole of it, house or business unit, across NW6, NW3 and NW2. Beyond the town, we take on jobs in Hampstead (1 mile) and Cricklewood (1 mile) as standard. Each one gets the same survey or photo-based pricing, the same written quote, and the same fitting standard.

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 Kilburn

Do you make good inside after fitting?

Yes, where the quote includes it. Internal finishing usually means lining the reveal with plasterboard, taping or skimming, and fitting trim where it meets the ceiling. Some people prefer their own plasterer or decorator to finish off, which is fine. The written quote spells out exactly where our work stops, so nobody is left guessing about who does what once the unit is in.

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.
