How we approach ridge & pitched glass roofs in Sevenoaks
Ridge & pitched glass roofs in Sevenoaks means dual-pitch glazed roofs for side returns, links and long extensions. We cover the TN13 district and the rest of Kent, with a survey before any price is fixed.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. In Sevenoaks, as anywhere, ridge & pitched glass roofs are the usual choice for terraced-house side returns that would otherwise be dark.
We work across Kent, including Sevenoaks, and in neighbouring towns such as Tonbridge and Orpington. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Sevenoaks
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.

Ridge & pitched glass roofs in Sevenoaks: questions
Will it be noisy in the rain?
Glass is quieter than polycarbonate. Triple glazing or laminated glass reduces rain noise further.
How long does a ridge roof take to fit?
Typically two to four days once the walls and supports are ready, depending on length and access.
Can it be partly solid?
Yes — part-glazed, part-insulated roofs balance light and heat.
Will I need planning permission in Sevenoaks?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line.
Do I need to be at home for the survey in Sevenoaks?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
