How we approach ridge & pitched glass roofs in Belfast
For Belfast 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.
Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting. In Belfast, as anywhere, ridge & pitched glass roofs are the usual choice for side returns, links and long extensions.
We cover all of Belfast and the BT1 district, and nearby Castlereagh and Newtownabbey.
Specification options
- Aluminium systems in standard and RAL colours
- Fixed or retractable shading
- Dual-pitch or mono-pitch
- Opening vents and electric actuators
- Solar-control, self-cleaning or tinted glass
- Solar-control glass for south-facing slopes
- Slim aluminium glazing bars
Before you order: points to check
- Overheating is a real risk on south-facing glass roofs
- Large glass roofs affect the energy calculation for the extension
Do you need permission in Belfast?
Most rooflights on houses in Northern Ireland are permitted development under Class B, but not in a conservation area or on a listed building's curtilage. A side-facing window within 15 m of a neighbouring boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Northern Ireland's energy rules assess rooflight U-values in the vertical position — unlike England and Wales — and expect 1.6 W/m²K or Band C for replacements. Extensions follow a 25% glazing allowance in Technical Booklet F1.

The process, step by step

- Free site visit. For new installs we survey free, measure and confirm the roof detail.
- Fixed quote. Product, work and price in writing — nothing is ordered until you agree.
- Fit and make good. We fit, seal, test and finish the reveal, then hand over the paperwork.

Questions about ridge & pitched glass roofs in Belfast
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.
Will it be noisy in the rain?
Glass is quieter than polycarbonate. Triple glazing or laminated glass reduces rain noise further.
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.
