How we approach pitched roof windows in Sittingbourne
Thinking about pitched roof windows in Sittingbourne? The short answer: centre-pivot and top-hung skylights for tiled and slate roofs. The longer answer depends on your roof, which is why we survey before we price.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Typical uses for pitched roof windows include pitched roofs over bedrooms, stairs and bathrooms.
We work across Kent, including Sittingbourne, and in neighbouring towns such as Faversham and Gillingham. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for Sittingbourne
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.
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Pitched roof windows in Sittingbourne: questions
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 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 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.
Can you work alongside my builder in Sittingbourne?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Sittingbourne?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
