Ridge & pitched glass roofs in Horsham: what is involved?
Thinking about ridge & pitched glass roofs in Horsham? The short answer: dual-pitch glazed roofs for side returns, links and long extensions. The longer answer depends on your roof, which is why we survey before we price.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Typical uses for ridge & pitched glass roofs include side returns, links and long extensions.
Horsham is around 12 km from Crawley, and we survey and fit throughout that part of West Sussex, including the RH12 district.

Do you need permission in Horsham?
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.
