Ridge & pitched glass roofs for Islington: the essentials
Our ridge & pitched glass roofs service in Islington covers dual-pitch glazed roofs for side returns, links and long extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Ridge & pitched glass roofs suit side returns, links and long extensions.
Islington sits about 2 km from Highbury and 2 km from Holloway, and we cover the whole N1 postcode district and the roads in between.

Planning and building rules for Islington
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
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.
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.
Do I need to be at home for the survey in Islington?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Islington?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
