Ridge & pitched glass roofs in Farnham: what is involved?
We handle ridge & pitched glass roofs across Surrey, including Farnham. In short: dual-pitch glazed roofs for side returns, links and long extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Ridge & pitched glass roofs suit terraced-house side returns that would otherwise be dark.
We work across Surrey, including Farnham, and in neighbouring towns such as Aldershot and Fleet. Access, parking and how the glass reaches the roof are all checked at the survey.

What to check first

Planning, building control and Farnham
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.
Read the planning permission guide before you commit to a design.

Common questions
Will it be noisy in the rain?
Glass is quieter than polycarbonate. Triple glazing or laminated glass reduces rain noise further.
Is a glass roof too hot for a kitchen?
Without care, it can be. Solar-control glass, an opening vent at the top and a blind make a south-facing glass roof comfortable.
Can it be partly solid?
Yes — part-glazed, part-insulated roofs balance light and heat.
Is the survey in Farnham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Farnham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
