Liquid-applied roofing in Dundonald

Liquid-applied roofing in Dundonald: primer, reinforced base coat and top coat, built up wet to form a single jointless membrane. It goes on cold, follows any shape and, where the old roof is sound, can often be laid without stripping. Our vetted teams work under S&K from survey to final check.

Why choose a liquid-applied roof in Dundonald?

Liquid systems suit balconies and walkways in Dundonald because they form neatly at door thresholds, railings and drains, and some products are designed to take foot traffic. Converting a roof into a new terrace is a different matter, and usually needs planning permission first.

Around Dundonald, flat roofs are common on shops with flat-roofed rear stores below flats and on terraced streets with flat-roofed rear kitchens and bathrooms. 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?

  • Detailing of upstands, outlets, pipes and corners before the main area
  • Top coat with optional anti-slip finish, and guarantee registration where available
  • Surface cleaning, repairs and removal of loose material
  • Survey of the existing roof, including moisture and adhesion checks

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.
