How we approach hinged roof access rooflights in Portsmouth
Thinking about hinged roof access rooflights in Portsmouth? The short answer: hinged glazed hatches over a stair or ladder for roof terrace access. The longer answer depends on your roof, which is why we survey before we price.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. In Portsmouth, 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.
Neighbouring towns include Gosport (3 km) and Fareham (9 km). We offer a survey date when we reply to your enquiry.

- Grab rail or handle inside

Do you need permission in Portsmouth?
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.
