Pitched roof window installation in Wembley

Our guide price for pitched roof window installation starts from £845, and the real figure for your roof in Wembley depends on a handful of things: the size and type of pitched roof window, whether the opening exists already, the roof covering, and how easy access is. We fix the price in a written quote before work begins. Nothing gets added on the day without your say-so. For a rough idea first, photos and a couple of measurements are enough to go on, and we cover all of Greater London.

Areas around Wembley we cover

Wembley and the districts around it, HA0, HA9 and UB6, all sit inside our working area. So does the ground between Wembley and Brent (1 mile), and on towards Harlesden (2 miles). When a fitting team is booked, their travel is already in the quoted price, so it does not turn up as a surprise line on the final bill.

Fit-only or supply and fit

Supply and fit tends to suit people who would rather not pick a unit from a catalogue. We look at the roof, the opening and how you use the room, then put a pitched roof window on the quote that fits all three. Fit-only suits people who already know what they want, or have one on site. We are happy with either. The difference is who stands behind what: on fit-only, the maker or retailer covers the product, and our workmanship guarantee covers the installation.

Included in the work

  • Underlay collar or membrane dressed and taped around the frame
  • Rafters trimmed where the window is wider than the gap between them
  • Insulation collar and vapour layer fitted to stop a cold edge
  • Flashing to suit the roof — We match the flashing kit to your roof covering before ordering.
  • Side slopes and neighbours — We check which slope the window is going on before you commit.

Fitting your pitched roof window, 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 pitched roof window, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.

Do you need permission in Wembley?

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.

What to send for a quick quote

Keep it simple. Two or three photos, outside and inside. Approximate sizes. What the roof is made of. Anything awkward about getting up there, such as a conservatory below, a narrow side path or no parking. If you bought the rooflight online, the link or model name. Then your postcode in or around HA0. That is enough for a first price.

Common questions in Wembley

How long does fitting take?

Fitting a pitched roof window 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.

Do you cover Wembley?

Yes. Fitters travel to addresses in Wembley and the surrounding districts, including HA0. We do not run an office there; the survey and the fitting happen at your property. A few island and remote postcodes are covered by arrangement; if yours is one, we confirm travel and dates before quoting.

Can you remove and dispose of the old rooflight?

Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.
