Why use a rooflight fitting specialist

Water has to go somewhere. Around a rooflight, the roof falls should carry it away from the kerb, not towards it. The glass itself needs enough pitch to shed rain and stop dirt settling. Condensation needs a path out of the frame. Get any of this wrong and the result is ponding, staining or drips months later. A specialist fitter checks these details as a matter of course, because they are the difference between a rooflight that works and one that turns into a repair job.

Postcodes and places we cover

Covering Hammersmith properly means covering the whole of it, house or business unit, across W6, W14 and W12. Beyond the town, we take on jobs in Shepherds Bush (1 mile) and Fulham (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

In England, a new rooflight opening generally needs building regulations approval because the roof structure is altered and the glazing must meet energy rules: 2.2 W/m²K for a rooflight in an existing home, or 1.4 W/m²K (or WER Band B) for a roof window. Planning is often not needed on a house: permitted development covers rooflights that stand no more than 0.15 m proud of the roof slope and sit below the highest part of the roof. Flats, listed buildings and areas with an Article 4 direction are different, so we check your address first.

Questions about rooflight fitting in Hammersmith

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.

Does a rooflight need building regulations approval?

A new opening usually needs building regulations approval. A replacement is a controlled fitting: it must be self-certified by an installer registered with a competent person scheme or notified to building control. We are not registered with a scheme, so replacements we fit are notified to building control with a building notice, and the council's fee is shown on your quote.

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 upstand height and roof pitch does rooflight fitting need?

It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.
