What do ridge & pitched glass roofs involve?
Across Lancashire, our ridge & pitched glass roofs work covers dual-pitch glazed roofs for side returns, links and long extensions. Survey first, fixed price second, fitting third.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed.

Planning and building rules in England
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. 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.

Common questions
Can it have opening vents?
Yes, top-hung vents with electric actuators are common, often with a rain sensor.
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.
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.
Will I need planning permission in Lancashire?
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.
