How we approach pitched roof windows in Crowthorne
For Crowthorne homes and buildings we offer pitched roof windows: centre-pivot and top-hung skylights for tiled and slate roofs. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Typical uses for pitched roof windows include lofts, attic rooms, landings and vaulted ceilings.
We work across Berkshire, including Crowthorne, and in neighbouring towns such as Sandhurst and Yateley. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Crowthorne
- Flashings for tiles, slates or recessed fitting
- Combination and stacked windows
- Double or triple glazing

What to check first

Planning, building control and Crowthorne
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. 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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

Questions about pitched roof windows in Crowthorne
Can a roof window be fitted from inside?
In most cases, yes — only the tiles around the opening are lifted, and much of the work is done from inside the loft.
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.
Can roof windows be electric?
Yes — electric and solar-powered models open by remote and many include rain sensors.
Is the survey in Crowthorne free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Crowthorne?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
