What we fit in St Ives
From flat-roof extensions to period slate roofs, we fit the right rooflight for the building in St Ives — after a survey, with a fixed written price.
Many homes in the East have low-pitched roofs on later extensions, which are better served by flat rooflights than pitched roof windows.
Jobs in St Ives are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

Planning and building rules in England
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.

Skylight questions: St Ives
Is the survey in St Ives free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in St Ives?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in St Ives?
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 St Ives?
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.
Will a rooflight make my room too hot?
It can on a south-facing roof with clear glass. Solar-control glass, an opening unit and a blind keep the room comfortable.
Can a skylight be fitted into an existing flat roof?
Yes. We form the opening, trim joists, build an insulated upstand, re-waterproof and make good the ceiling.
