Why choose a liquid-applied roof in Carryduff?

Choose liquid roofing in Carryduff when the shape of the roof makes sheet materials awkward: curved edges, small dormers with many corners, or a mix of levels joined by short upstands. Each detail is reinforced in the same material as the main area, so the whole roof is continuous.

In and around Carryduff, flat roofs are typically found on bungalows with flat-roofed side extensions and dormers, and on shops with flat-roofed rear stores below 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 long does a liquid-applied roof last, and how is it guaranteed?

Cold liquid-applied roofs typically last 10 to 25 years or more, depending on the product and the thickness applied. One reinforced system has a BBA assessment of over 25 years, while lighter coatings designed to extend an existing roof sit at the lower end of the range.

Because life varies so much by product, it pays to know exactly what is being applied. Your quote should name the system, the reinforcement and the build-up.

Manufacturer guarantees are often tied to a named system, with lengths such as 10, 15 or 20 years depending on the specification, and some require registration or an approved applicator. We handle that registration where the system permits it. Every re-roof also carries our written workmanship guarantee, with the length set out in the quote, and you can ask about insurance-backed options. A BBA certificate is a product assessment, not a guarantee; our guarantees guide explains the difference.

What's included?

  • Survey of the existing roof, including moisture and adhesion checks
  • Surface cleaning, repairs and removal of loose material
  • Top coat with optional anti-slip finish, and guarantee registration where available
  • Fleece-reinforced liquid membrane applied to the specified thickness

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.
