How we approach ridge & pitched glass roofs in Formby
For Formby homes and buildings we offer ridge & pitched glass roofs: dual-pitch glazed roofs for side returns, links and long extensions. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Ridge & pitched glass roofs suit terraced-house side returns that would otherwise be dark.
Formby sits about 10 km from Maghull and 10 km from Southport, and we cover the whole L37 postcode district and the roads in between.
Specification options
- Fixed or retractable shading
- Dual-pitch or mono-pitch
- Aluminium systems in standard and RAL colours
- Opening vents and electric actuators
- Integrated gutters and box gutters
- Works with exposed brick and period detail
- Solar-control glass for south-facing slopes
Things we check at survey
- Junctions with existing walls need lead or flashing detail
- Overheating is a real risk on south-facing glass roofs
Planning, building control and Formby
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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. 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.

Ridge & pitched glass roofs in Formby: questions
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.
Will it be noisy in the rain?
Glass is quieter than polycarbonate. Triple glazing or laminated glass reduces rain noise further.
Can you work alongside my builder in Formby?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Formby free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
