Pitched roof windows in Altrincham: what is involved?
Thinking about pitched roof windows in Altrincham? 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.
The North West gets more rain than most of England, so upstand height, membrane detailing and rain sensors on opening units are not optional extras. Pitched roof windows suit lofts, attic rooms, landings and vaulted ceilings.
Jobs in Altrincham 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.
Specification options
- Manual, electric or solar-powered opening
- Flashings for tiles, slates or recessed fitting
- Integral blinds and shutters

- Centre-pivot or top-hung
- Daylight and ventilation in a pitched roof
- Usually fitted in a day
Before you order: points to check
- Escape-window rules can apply to loft rooms
- Insulation collars and vapour control must be detailed
Planning, building control and Altrincham
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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.
Read the planning permission guide before you commit to a design.

Common questions
Do I need planning permission for a roof window?
Often not, under householder permitted development, provided it does not project too far above the roof plane and conditions are met. Listed buildings, flats and some conservation areas are different. Our planning guide covers each nation.
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.
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.
Do I need to be at home for the survey in Altrincham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Altrincham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
