How we approach pitched roof windows in Accrington
Our pitched roof windows service in Accrington covers centre-pivot and top-hung skylights for tiled and slate roofs. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. In Accrington, as anywhere, pitched roof windows are the usual choice for pitched roofs over bedrooms, stairs and bathrooms.
Jobs in Accrington are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

Do you need permission in Accrington?
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.

Common questions
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 it need building regulations approval?
Fitting a new roof window usually involves cutting rafters and changing the thermal envelope, so building control approval (or, in England and Wales, a competent-person route) is normally needed. We tell you which applies.
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 work alongside my builder in Accrington?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Accrington free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
