Flat Roofing in Northern Ireland

Flat roofs are everywhere in Northern Ireland, covering kitchen extensions, garages, porches, dormers and garden rooms. They are practical and affordable, but they need to be installed properly to cope with our rainfall. RoofersNI connects you with fully insured local roofers who specialise in flat roofing.

EPDM rubber roofing is laid as a single seamless sheet, is highly resistant to weather and UV and can last 30 to 50 years. GRP fibreglass forms a hard, seamless surface that is ideal for roofs with foot traffic and lasts 25 years or more. Traditional felt, now usually torch on built up felt, is cost effective and modern versions can last 15 to 25 years.

Older felt roofs on NI extensions and garages often suffer from blistering, cracking, splits at joints and ponding water where the deck has sagged. Leaks can track a long way before showing up inside, so water staining on a ceiling may not sit directly under the problem.

If the roof is relatively young and the damage is local, a patch repair may be all that is needed. If it is leaking in several places, the deck is soft or the felt is past 20 years old, replacement with EPDM or GRP is usually better value long term.

In Belfast, countless terraces have back return extensions with ageing felt roofs. In Lisburn, many estate homes built in the 1980s and 1990s have garages and kitchen extensions that are now due for renewal.
