Hinged roof access rooflights in Streatham: what is involved?
For Streatham 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. Typical uses for hinged roof access rooflights include reaching a roof terrace, plant area or flat roof from a stair or ladder.
Jobs in Streatham 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.

What to check first

Do you need permission in Streatham?
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.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

Common questions
Does it let in as much light as a normal rooflight?
Yes — closed, it is a glazed rooflight. The frame is slightly deeper to carry the hinge and seals.
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.
Can you work alongside my builder in Streatham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Streatham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
