Rooflight installers in Greenford

Homes and commercial buildings in Greenford need different things from a rooflight. A kitchen extension wants a lantern or flat glass rooflight that brings in daylight and holds on to heat. A warehouse may need old domes replaced, smoke-vent rooflights renewed, or an access hatch fitted for maintenance. We work on both sides across Greater London, covering fit-only, replacement, new openings and trade fitting for contractors. The fitting principles do not change: right opening, right upstand, maker's instructions, sound weather seal.

The details a specialist gets right

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.

Is your Greenford address covered?

From the centre of Greenford out to its edges, postcode districts UB6, UB1 and UB5 are all standard cover. The same applies to neighbouring Northolt, about 1 mile off, and Southall, around 2 miles away. If you are further out, towards West Ealing or beyond, send the postcode and we will confirm before quoting.

Planning and building control

Replacing a rooflight in an English home is a controlled fitting: it has to be self-certified by a scheme-registered installer or notified to building control. We are not registered with a competent person scheme, so replacements we fit are notified with a building notice, and the new unit has to meet current energy limits. Adding a new one usually means a building regulations application, because joists or rafters are trimmed. On the planning side, most house rooflights are permitted development if they project 0.15 m or less; on a side slope the glass must be obscured and fixed unless the opening part is over 1.7 m above the floor.

Questions about rooflight fitting in Greenford

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.

How long does fitting take?

Fitting a rooflight into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.

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 fit the rooflight I bought online?

Yes, fit-only is one of our core services. Send the product link or spec, photos of the roof and rough sizes, and we can usually price it from those. Before fitting we check the delivery for damage, which should be reported to the seller, plus the size against the builder's opening and the upstand height. The product warranty stays with the maker or seller, and our guarantee covers the fitting.
