Flat rooflights in Ballymena: what is involved?
Thinking about flat rooflights in Ballymena? The short answer: fixed double or triple glazed rooflights for flat roofs and extensions. The longer answer depends on your roof, which is why we survey before we price.
Northern Ireland has a mix of terraces, bungalows and rural farmhouses, and rooflights are a common upgrade when extending. Typical uses for flat rooflights include kitchen extensions, side returns and flat-roofed back rooms.
Neighbouring towns include Magherafelt (24 km) and Newtownabbey (33 km). We offer a survey date when we reply to your enquiry.

Do you need permission in Ballymena?
In Northern Ireland, roof alterations come under Class B of the 2015 order: a rooflight facing a road must not project more than 15 cm and must sit at least 0.5 m from the ridge, eaves, verge and party wall. 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.
For homes in Northern Ireland, Technical Booklet F1 sets 1.6 W/m²K (or WER Band C) for replacement glazing including rooflights. New dwellings must average 1.40 W/m²K across windows, roof windows and rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Flat rooflights in Ballymena: questions
How long does it take?
Fitting into a prepared upstand usually takes a day. Forming a new opening in an existing roof, including making good inside, is often two to three days.
Do flat rooflights leak?
A well-fitted flat rooflight should not leak. Leaks almost always come from the upstand or membrane detailing, not the glass unit, which is why the upstand height and the way the roof covering is dressed up and under the frame matter more than the brand.
Can a flat rooflight be walked on?
Not unless it is designed as a walk-on unit with structural laminated glass. A standard flat rooflight is for light only — if the roof is used as a terrace, choose a walk-on rooflight instead.
Do you fit flat rooflights in Ballymena?
Yes. We survey and fit flat rooflights in Ballymena and across County Antrim. Send your postcode and we will offer a survey date when we reply.
Is the survey in Ballymena free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
