Liquid-applied roofing in Rushden

Our liquid roofing service in Rushden and across Northamptonshire covers overlays of sound roofs, full re-roofs with a new deck and insulation, and repairs to failing details. Every job starts with careful preparation, because a liquid membrane only performs when it is bonded to a clean, dry and stable surface.

Why choose a liquid-applied roof in Rushden?

Liquid roofing suits a roof in Rushden 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 a town like Rushden, flat roofs are commonly found on 1960s and 1970s link-detached houses with flat-roofed garages and porches or low-rise post-war blocks of flats. The East Midlands is drier than the west of Britain, so most flat roofs here fail through age, UV and poor detailing at upstands rather than sheer rainfall.

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

At East Midlands guide rates, a typical 18 m² garage roof in a liquid-applied system comes to £2,000–£3,200 including VAT. 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?

  • 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
  • Fleece-reinforced liquid membrane applied to the specified thickness

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.

£2,000–£3,200 for a typical 18 m² garage roof in a liquid-applied system, at East Midlands guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

Does a liquid roof smell when it is applied?

Some systems, particularly PMMA, have a strong odour during application, while many polyurethane and water-based products are milder. We tell you what to expect and plan around windows and vents.

Is liquid roofing the same as a roof paint?

No. A proper liquid-applied membrane is built to a specified thickness and usually reinforced with fleece, while roof paints and simple coatings are much thinner and mainly used to extend the life of an existing covering.
