How we approach pitched roof windows in Runcorn
We handle pitched roof windows across Cheshire, including Runcorn. 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.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Pitched roof windows suit lofts, attic rooms, landings and vaulted ceilings.
Runcorn sits about 2 km from Widnes and 7 km from Halewood, and we cover the whole WA7 postcode district and the roads in between.

Planning, building control and Runcorn
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.

Questions about pitched roof windows in Runcorn
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.
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.
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.
Do I need to be at home for the survey in Runcorn?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Runcorn free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
