How we approach hinged roof access rooflights in Coulsdon
Our hinged roof access rooflights service in Coulsdon covers hinged glazed hatches over a stair or ladder for roof terrace access. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
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. In Coulsdon, as anywhere, hinged roof access rooflights are the usual choice for reaching a roof terrace, plant area or flat roof from a stair or ladder.
Coulsdon sits about 3 km from Purley and 5 km from Banstead, and we cover the whole CR5 postcode district and the roads in between.

Planning, building control and Coulsdon
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.
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.
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.
