What do pitched roof windows in Bexleyheath involve?
Thinking about pitched roof windows in Bexleyheath? The short answer: centre-pivot and top-hung skylights for tiled and slate roofs. The longer answer depends on your roof, which is why we survey before we price.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Typical uses for pitched roof windows include pitched roofs over bedrooms, stairs and bathrooms.
We work across Greater London, including Bexleyheath, and in neighbouring towns such as Welling and Bexley. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for Bexleyheath
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
