Pitched roof windows for Slough: the essentials
We handle pitched roof windows across Berkshire, including Slough. In short: centre-pivot and top-hung skylights for tiled and slate roofs. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Pitched roof windows suit lofts, attic rooms, landings and vaulted ceilings.
Slough sits about 3 km from Windsor and 9 km from Maidenhead, and we cover the whole SL1 postcode district and the roads in between.

Do you need permission in Slough?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

Pitched roof windows in Slough: questions
Can roof windows be electric?
Yes — electric and solar-powered models open by remote and many include rain sensors.
Centre-pivot or top-hung?
Centre-pivot windows are easy to clean and suit most rooms. Top-hung windows open out from the top for an unobstructed view and suit lower roof pitches near eye level.
Can you replace an old roof window?
Yes — replacement into the same opening is usually quicker than a new install, often a few hours per window.
Will I need planning permission in Slough?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge.
How do I book a survey in Slough?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
