Liquid-applied roofing in Greenock

Our liquid roofing service in Greenock and across Inverclyde 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 Greenock?

If a flat roof in Greenock is ageing but still dry, firmly bonded and on a sound deck, a reinforced liquid system can be applied over it. That avoids the cost and mess of a full strip-out, provided the moisture and adhesion checks at survey show the existing roof is fit to build on.

In a town like Greenock, flat roofs are commonly found on newer estates where the first extension roofs are now being replaced or terraced streets with flat-roofed rear kitchens and bathrooms. Scotland averages roughly 1,570 mm of rain a year, with the west far wetter than the east, so drainage, falls and wind uplift are part of every specification we write.

Can a liquid roof go over my existing roof, and what preparation is needed?

Yes, if the existing roof is dry, firmly bonded and sitting on a sound deck. A liquid membrane is only as good as what lies beneath it, so we test the old roof before agreeing to overlay it.

At survey we check for:

  • Trapped moisture: soft spots, blisters or wet insulation mean the roof should be stripped, because water sealed in will cause new blisters and decay.
  • Deck condition: any sponginess or deflection needs repair first.
  • Adhesion: on felt and asphalt, loose areas are cut out and patched, and the existing surface must take the primer properly.
  • Falls and ponding: a coating follows the roof as it is. If water ponds now, it will pond on the new surface too unless the falls are corrected.

Preparation then follows: loose chippings removed, the surface cleaned and left to dry, blisters cut back and repaired, cracks filled, and the right primer applied. On older felt, mineral surfaces may need extra cleaning to give a good bond. Where the tests fail, we say so plainly and quote for a strip and re-roof. Read more on ponding water.

What's included?

  • Fleece-reinforced liquid membrane applied to the specified thickness
  • Top coat with optional anti-slip finish, and guarantee registration where available
  • Primer matched to the substrate
  • Surface cleaning, repairs and removal of loose material

Building standards in Scotland

In Scotland the building standards technical handbooks (Section 6 for energy) apply, and the council's building standards service decides whether a building warrant is needed. Like-for-like repairs to a roof covering can be exempt; alterations, structural work and new roofs usually need a warrant before work starts. The domestic roof benchmark is 0.12 W/m²K, applied as far as reasonably practicable on an existing roof. More on the rules.

Liquid-applied roofing in Greenock: questions

Who checks building standards for a flat roof in Greenock?

Where the work needs approval it goes to Inverclyde Council building standards. We tell you at the survey whether your job needs it and deal with the paperwork as part of the quote.

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

£1,950–£3,100 for a typical 18 m² garage roof in a liquid-applied system, at Scotland 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.
