What do pitched roof windows in Thornaby-on-Tees involve?
For Thornaby-on-Tees 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.
Many Yorkshire homes have had kitchen extensions with flat roofs, where a larger glass rooflight is a straightforward upgrade from an old dome. Think of pitched roof windows for lofts, attic rooms, landings and vaulted ceilings.
We work across North Yorkshire, including Thornaby-on-Tees, and in neighbouring towns such as Stockton-on-Tees and Billingham. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Combination and stacked windows
- Double or triple glazing
- Manual, electric or solar-powered opening
- Flashings for tiles, slates or recessed fitting
- Centre-pivot or top-hung
- Usually fitted in a day
- Daylight and ventilation in a pitched roof
What to check first
- Escape-window rules can apply to loft rooms
- Insulation collars and vapour control must be detailed
Planning, building control and Thornaby-on-Tees
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Pitched roof windows in Thornaby-on-Tees: questions
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.
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.
