Rooflight installers in Cambridge

Homes and commercial buildings in Cambridge 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 Cambridgeshire, 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.

Commercial & trade

Specialist fitting or a general builder

Builders run many trades at once, and the rooflight often gets squeezed in between the roofer and the plasterer. That is when corners get cut: an upstand built a little low, sealant applied in damp conditions, a reveal left rough. Bringing in a fitting specialist for that one stage means someone is focused on it alone, following the maker's instructions, with time set aside to finish the inside properly. The builder keeps control of the programme, and the rooflight gets proper attention.

Nearby towns we also cover

Covering Cambridge properly means covering the whole of it, house or business unit, across CB2, CB4 and CB1. Beyond the town, we take on jobs in Royston (12 miles) and St Ives (12 miles) 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

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 Cambridge

Do you offer trade rates for builders and roofers?

We carry out subcontract fitting for builders, roofers, extension companies and commercial contractors. Pricing is per job or per schedule of units, agreed in writing before we start. We can work to your programme, fit on your upstand or build our own, and leave the opening ready for the next trade. Send drawings or a unit schedule and we will come back with a trade 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.

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.

Do I need planning permission for a rooflight in Cambridge?

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.
