Fit-only rooflight installation in Crowthorne

Plenty of rooflight trouble starts with a tape measure. Units are often sold by the builder's opening, meaning the hole in the roof, rather than the overall external size, and confusing the two leaves you with a frame that does not suit the opening. Before we fit any rooflight in Crowthorne, we measure the opening, the upstand or kerb where there is one, and the finished roof level, then compare them with the maker's drawing. If something is out, you hear about it before the fitting day rather than on it. That single check keeps most jobs like this on track.

Guide ranges for labour only — you supply the rooflight. Your price is fixed in a written quote after we have seen photos or surveyed. Scaffold, access towers or a crane are priced separately if the job needs them, and building control fees, where a job needs them, are shown as their own line.

Covering RG45 and neighbouring districts

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.

Already bought your unit?

A damaged delivery is a frequent snag on fit-only work. Before the day, unpack a rooflight, photograph it, and tell the seller about any cracks or scuffs, because claims are much easier made early. We will also ask for the model or a link, so we can read the maker's instructions and check the builder's opening size and the upstand height it expects. If everything lines up, we fit it. If not, we explain what needs changing first.

Included in the work

  • Opening and upstand measured against the maker's drawing, timber to timber
  • Internal reveal trimmed or lined, with the protective film removed at the end
  • Upstand height, level and fall checked, and squareness confirmed across the diagonals
  • Internal versus external size — We check whether your rooflight's quoted size is the hole size or the outer frame size.
  • Access and lifting — We check how the unit gets from your drive to the roof.

Fitting your rooflight, step by step

On the day, you need to be in at the start and at the end. In between, the fitters get on with it. They will want the room below cleared where possible, a parking spot if you have one, and somewhere to set the unit down safely. After checking the opening and the upstand or flashing, they fix a rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.

Do you need permission in Crowthorne?

Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the quote.

Before you get in touch

What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around RG45 and we will come back with a quote or a survey date.

Common questions in Crowthorne

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.

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 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.
