Ridge & pitched glass roofs for Clapham: the essentials
Our ridge & pitched glass roofs service in Clapham covers dual-pitch glazed roofs for side returns, links and long extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Think of ridge & pitched glass roofs for terraced-house side returns that would otherwise be dark.
Neighbouring towns include Balham (2 km) and Battersea (2 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Clapham
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
Read the planning permission guide before you commit to a design.

Common questions
Can it be partly solid?
Yes — part-glazed, part-insulated roofs balance light and heat.
Will it be noisy in the rain?
Glass is quieter than polycarbonate. Triple glazing or laminated glass reduces rain noise further.
Do I need a party wall agreement?
If the work affects a party wall or boundary, the Party Wall etc. Act 1996 may apply in England and Wales. We flag this at survey so you can serve notice in time.
Do I need to be at home for the survey in Clapham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Clapham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
