How we approach hinged roof access rooflights in Chiswick
For Chiswick 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.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Hinged roof access rooflights suit reaching a roof terrace, plant area or flat roof from a stair or ladder.
Jobs in Chiswick 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.

Consents for hinged roof access rooflights in Chiswick
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. 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.

Hinged roof access rooflights in Chiswick: questions
Is it secure?
Units lock from inside. As with any rooftop door, keep it locked when the house is empty.
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.
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 the survey in Chiswick free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
