How we approach pitched roof windows in Sudbury
We handle pitched roof windows across Suffolk, including Sudbury. 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.
Coastal towns in the East of England see salty air, so we specify frame finishes and fixings with exposure in mind. In Sudbury, as anywhere, pitched roof windows are the usual choice for lofts, attic rooms, landings and vaulted ceilings.
Sudbury sits about 20 km from Colchester and 21 km from Haverhill, and we cover the whole CO10 postcode district and the roads in between.
What you can choose
- Centre-pivot or top-hung
- Flashings for tiles, slates or recessed fitting
- Integral blinds and shutters
- Double or triple glazing
- Combination and stacked windows
- Daylight and ventilation in a pitched roof
- Flashings to suit tiles or slates
What to check first
- Rafters may need trimming for wider windows
- Insulation collars and vapour control must be detailed
Planning, building control and Sudbury
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.
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. 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.

Common 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.
Can a roof window be fitted from inside?
In most cases, yes — only the tiles around the opening are lifted, and much of the work is done from inside the loft.
Do I need to be at home for the survey in Sudbury?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Sudbury?
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.
