How we approach hinged roof access rooflights in St Austell
For St Austell homes and buildings we offer hinged roof access rooflights: hinged glazed hatches over a stair or ladder for roof terrace access. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. Typical uses for hinged roof access rooflights include reaching a roof terrace, plant area or flat roof from a stair or ladder.
St Austell is around 22 km from Truro, and we survey and fit throughout that part of Cornwall, including the PL25 district.

What to check first

Planning, building control and St Austell
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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Hinged roof access rooflights in St Austell: questions
Can it replace an old loft hatch?
Where there is a flat roof above, yes. On a pitched roof, an access roof window is the equivalent.
Is it secure?
Units lock from inside. As with any rooftop door, keep it locked when the house is empty.
How big does an access hatch need to be?
Big enough to climb through comfortably for the stair or ladder you have. For a stair, we size it to the stair width and the headroom; for occasional plant access a smaller hatch can work.
