Why choose a liquid-applied roof in Irlam?
Where a building in Irlam has an older asphalt or concrete roof that is sound but tiring, a compatible liquid system can sometimes refresh it. The key is matching the primer and system to the substrate and dealing with any blisters, cracks or poor falls before the membrane goes on.
Around Irlam, flat roofs are common on bungalows with flat-roofed side extensions and dormers and on newer estates where the first extension roofs are now being replaced. The North West is one of England's wetter regions, averaging roughly 1,290 mm of rain a year, so falls, outlets and well-detailed upstands matter more than the membrane colour.
How much does a liquid-applied roof cost in Irlam?
For Irlam we use North West rates: £1,950–£3,100 is the guide for a typical 18 m² garage roof in a liquid-applied system, VAT included. The fixed price comes after a free survey for new and replacement roofs.

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?
- Fleece-reinforced liquid membrane applied to the specified thickness
- Survey of the existing roof, including moisture and adhesion checks
- Detailing of upstands, outlets, pipes and corners before the main area
- Primer matched to the substrate
Building regulations in England
Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.

How much does a liquid-applied roof cost in Irlam?
£1,950–£3,100 for a typical 18 m² garage roof in a liquid-applied system, at North West guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
Is liquid roofing good for balconies?
Often, yes. It forms neatly around railings, door thresholds and drains, and some systems take foot traffic. A new balcony or roof terrace generally needs planning permission, so check before converting a roof.
How long does a liquid roof take to cure?
That depends on the product and the weather. Some systems are rain-resistant within an hour or so, others take longer, and full cure can take a day or more in cool weather.
