What are ridge & pitched glass roofs?
Across Cornwall, 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Stone cottages, slate roofs and conservation areas are common in the South West, and conservation-profile rooflights keep the roofline quiet.

Planning and building rules in England
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. 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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

Common questions
Can it have opening vents?
Yes, top-hung vents with electric actuators are common, often with a rain sensor.
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.
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.
Do you fit ridge & pitched glass roofs across Cornwall?
Yes. We survey and fit ridge & pitched glass roofs across Cornwall, including Redruth, Falmouth, St Austell.
