Why choose a liquid-applied roof in Antrim?
Liquid roofing suits a roof in Antrim 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.
In and around Antrim, flat roofs are typically found on shops with flat-roofed rear stores below flats, and on low-rise post-war blocks of flats. 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 Antrim?
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.

Do building regulations apply if a liquid coating goes over my roof?
They can. In England, Wales and Northern Ireland, re-covering more than half of a roof over a heated room is usually renovation of a thermal element, even when the new membrane goes over the old, so the roof should be insulated towards the renovation standard where feasible; for a Scottish property, the local building standards team will confirm whether a warrant is required.
A minor coating repair to a small area is different from re-covering the whole roof. Where insulation is needed, an overlay is not always practical, because the insulation has to go under a new waterproof layer. In that case we may recommend stripping to the deck, fitting a warm roof and applying the liquid system on top. Where approval applies, we deal with the paperwork; details are on the building regulations page.
What's included?

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.

How much does a liquid-applied roof cost in Antrim?
£1,800–£2,850 for a typical 18 m² garage roof in a liquid-applied system, at Northern Ireland guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
Can liquid roofing be applied in the rain?
No. The surface must be dry, and most systems need a dry window while they cure. Some fast-curing products shorten that window, but the team will not apply onto a damp roof.
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.
