Rooflight glass replacement across County Antrim

Rooflight glass replacement in County Antrim

No two rooflight glass units in County Antrim cost exactly the same to fit, and a guide price only gets you so far.

We quote rooflight glass replacement across County Antrim with each of those spelt out. Send photos for a first figure, or arrange a survey where the job calls for one.

What's included

Sealed unit ordered to match or improve on the original glass
Joints water tested and the glass cleaned inside and out
Measuring visit to size the glass and identify its make-up
Condensation or a failed seal — We confirm whether the mist is inside the sealed unit or on the room-side surface.
Matching the glass make-up — We identify the existing glass so the replacement performs at least as well.

Rules that apply in Northern Ireland

Northern Ireland's building regulations set a minimum of WER Band C or 1.6 W/m²K for rooflights and roof windows in existing homes, assessed under Technical Booklet F1. New openings involve trimming the roof structure, so expect a building control application. Many house rooflights don't need planning permission, but conservation areas and listed buildings are excluded, and side windows near a boundary have obscure-glazing rules. We confirm what applies.

Common questions in County Antrim

Can you replace just the glass in my rooflight?

Often, yes. If the frame, gaskets and drainage are sound, a new sealed unit can go into the existing frame. If the frame has failed, is distorted or leaks around the edge, replacing the whole rooflight is usually the better answer, and we tell you that.

Can I upgrade the glass while it is being replaced?

Usually. Solar-control, self-cleaning, toughened or laminated glass can be specified as long as the frame can take the thickness and weight. We check that on the measuring visit and price the options side by side.

How long does new rooflight glass take?

The new sealed unit is made to the measured size, so there is a gap between the measuring visit and the fitting visit while it is produced. We give you the expected timing when we price the glass, and book the fitting once it has arrived.
