Why choose a liquid-applied roof in Ballymena?

Liquid roofing suits a roof in Ballymena that is full of penetrations, such as soil pipes, vents, aerial brackets and rooflights, because the liquid flows around each one and cures into a single skin. There are no cut pieces or taped corners to work loose over time.

Ballymena's flat roofs are mostly on lock-up garage blocks on estates, with plenty on shops with flat-roofed rear stores below flats too. Northern Ireland averages roughly 1,150 mm of rain a year, spread over many wet days, so a roof that sheds water quickly to clear outlets lasts far longer than one that holds puddles.

How much does a liquid-applied roof cost in Ballymena?

At Northern Ireland guide rates, a typical 18 m² garage roof in a liquid-applied system comes to £1,800–£2,850 including VAT. The fixed price comes after a free survey for new and replacement roofs.

When is a liquid roof the best option, and when is it not?

A liquid roof is often the best option for roofs crowded with pipes, vents and upstands, for balconies and walkways, and for overlaying a structurally sound roof that is starting to fail. It is the wrong choice when the deck is rotten, the insulation is wet or the falls are badly wrong.

Advantages: continuous finish with no laps; forms details around pipes and odd shapes easily; cold-applied with no flame; can often go over felt, asphalt or concrete; some systems take foot traffic.

Disadvantages: higher cost per square metre than felt or EPDM; needs dry weather and careful thickness control; only as good as the surface it is bonded to; product quality varies widely across the market.

For a straightforward re-roof on a fresh deck, EPDM or GRP may offer better value. Larger flat areas suit torch-on felt or single-ply. On a sound mastic asphalt roof, a compatible liquid system can sometimes be applied over it. See also our guide to overlay or strip.

  • Top coat with optional anti-slip finish, and guarantee registration where available

Building control in Northern Ireland

In Northern Ireland, Technical Booklet F1 sets roof insulation at 0.18 W/m²K when a roof over a heated room is renovated or newly built, where that's feasible. The district council's building control should be contacted before work starts, and we prepare the details it asks for. More on the rules.

Can liquid roofing stop a leak on a flat roof?

It can, if the leak is at a detail or the membrane is worn but the roof beneath is sound. If water has soaked the insulation or deck, coating over it will not cure the problem.

What is a fleece-reinforced liquid roof?

It is a liquid membrane with a polyester fleece embedded between coats. The fleece adds strength, helps control thickness and resists cracking where the surface moves slightly.
