What do hinged roof access rooflights in Blackheath involve?
For Blackheath 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.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Think of hinged roof access rooflights for reaching a roof terrace, plant area or flat roof from a stair or ladder.
Jobs in Blackheath 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.
Specification options
- Grab rail or handle inside
- Hinge side to suit the stair
- Manual gas-strut or electric opening
- Frame colour options
- Double or triple glazing
- Gas-strut or electric opening
- Lockable from inside
Before you order: points to check
- Roof edges people reach may need guarding
- Electric versions need a supply and a safety check
Planning, building control and Blackheath
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common 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.
Electric or manual?
Gas-strut hatches are simple and reliable. Electric hatches suit heavier lids, wider openings and anyone who would struggle to push a lid up.
Is it secure?
Units lock from inside. As with any rooftop door, keep it locked when the house is empty.
Is the survey in Blackheath 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 Blackheath?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
