Trade rooflight fitting in Crowthorne

Glass is heavy, and bigger units get heavy fast. Fitting a rooflight in Crowthorne 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 Berkshire.

Fitting across Crowthorne and nearby

Distance is rarely the deciding factor. A roof in Sandhurst, 2 miles from Crowthorne, gets the same survey, the same written quote and the same fitting process as one in RG45, GU47 and RG40. What changes the price is the job itself: size of unit, roof type, access and lifting. Yateley, around 2 miles out, is treated the same way.

On the day, we cover

  • A short note of anything we found that needs your attention
  • Flat rooflights fitted, sealed and trimmed on your kerbs
  • Pitched roof windows fitted with their flashing kits
  • Building control sign-off — We agree with you how building control is handled before fitting.
  • Upstand ready and to size — We ask for the upstands to be built to the maker's drawing before we arrive.

Fitting your rooflight, step by step

Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a rooflight: half a day to a day per unit, weather permitting.

Planning and building rules in England

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.

Details that speed up your quote

Each detail you send takes a question off our list. Photos inside and out show the opening and the ceiling. Rough measurements tell us the unit size. The roof covering tells us how it will be sealed in. Access notes tell us whether a tower or scaffold is needed. A product link, if you have one, lets us check it against the opening. Your postcode, RG45 or nearby, confirms travel.

Common questions in Crowthorne

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.

Can you fit a rooflight in winter or when it is raining?

Yes, within limits. Cold is less of a problem than wet, because membranes, primers and sealants need a dry surface to bond. We plan fitting days around the forecast and may move a date if heavy rain is due. If the roof has to be opened up, it is not left overnight without a temporary weather seal, so the room below stays dry while the work is finished.

How does payment work?

Payment terms are set out on your written quote before you accept it. Depending on the job, that may mean a deposit, stage payments for larger work, or payment on completion. The contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group. Nothing is added without your agreement: if something unexpected comes up, we discuss it and agree any change before carrying on.
