What do pitched roof windows in Truro involve?
We handle pitched roof windows across Cornwall, including Truro. In short: centre-pivot and top-hung skylights for tiled and slate roofs. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. Think of pitched roof windows for pitched roofs over bedrooms, stairs and bathrooms.
We cover all of Truro and the TR1 district, and nearby Falmouth and Redruth.

Planning, building control and Truro
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.

Questions about pitched roof windows in Truro
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 roof windows be electric?
Yes — electric and solar-powered models open by remote and many include rain sensors.
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 Truro?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
