Ridge & pitched glass roofs for Castlereagh: the essentials
Our ridge & pitched glass roofs service in Castlereagh 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.
Many Northern Irish homes have later flat-roofed kitchen extensions where an old dome can be swapped for glass. In Castlereagh, as anywhere, ridge & pitched glass roofs are the usual choice for terraced-house side returns that would otherwise be dark.
Jobs in Castlereagh are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

Planning, building control and Castlereagh
Northern Ireland's householder permitted development allows rooflights within limits — no more than 15 cm projection on road-facing slopes and a 0.5 m margin from ridge, eaves and party walls. Listed buildings also need listed building consent from the council.
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.

Common questions
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.
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 the survey in Castlereagh free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Castlereagh?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
