What do pitched roof windows in Penzance involve?
For Penzance 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.
Stone cottages, slate roofs and conservation areas are common in the South West, and conservation-profile rooflights keep the roofline quiet. Think of pitched roof windows for pitched roofs over bedrooms, stairs and bathrooms.
From Penzance to Camborne, Redruth and Falmouth, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Double or triple glazing
- Combination and stacked windows
- Flashings for tiles, slates or recessed fitting
- Centre-pivot or top-hung
- Manual, electric or solar-powered opening
- Fits between rafters in most roofs
- Usually fitted in a day
What to check first
- Insulation collars and vapour control must be detailed
- Front-facing roof windows can need permission in conservation areas
Planning, building control and Penzance
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about pitched roof windows in Penzance
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 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 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.
Do I need to be at home for the survey in Penzance?
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 Penzance?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
