LIQUID ROOFING FOR COMMERCIAL & AGRICULTURAL BUILDINGS
We apply liquid roofing systems to commercial flat roofs where refurbishment or complex detailing make sheet membranes impractical.
The cold-applied coating bonds directly to the surface, allowing us to create a seamless protective layer around plant, penetrations and irregular roof shapes.
When do you need commercial liquid roofing repair or refurbishment?
Liquid systems are commonly considered where:
- Flat roofs show widespread surface wear
- Existing coverings are reaching the end of their service life
- Localised defects are appearing across larger areas
- Budget constraints make full renewal impractical
In some cases, liquid application provides a practical refurbishment route without full strip-out.
Our commercial liquid roofing services
Our commercial liquid roofing work includes:
- Application of specialist liquid coatings
- Refurbishment of ageing flat roofs
- Detailing around vents, ducts and equipment
- Reinforcement of vulnerable junctions
- Connection with existing drainage and edge systems
Liquid systems are a good option for roofs with irregular layouts or multiple service penetrations, where typical membranes would require extensive cutting and jointing.
We also apply liquid systems as part of phased refurbishment strategies where appropriate.
Why choose commercial liquid roofing?
Liquid roofing earns its place on the more complex jobs, where membranes would require extensive cutting and jointing, or where the budget doesn’t support full renewal.
- Bonds directly to most existing substrates – concrete, metal, felt, single-ply – without requiring a full strip first
- Applied in liquid form, it bridges minor surface imperfections
- Different grades of reinforcement available, from light-use maintenance coatings to fully reinforced systems with extended design lives
Suitability depends on deck condition and moisture levels but we will provide you with a full assessment.
FAQ’s
Can liquid roofing be applied in all weather conditions? +
No. As a cold-applied system, it requires suitable dry conditions during installation to ensure proper curing and adhesion.
Can liquid roofing cope with rooftop access and equipment? +
Yes, when correctly specified. Reinforced systems can accommodate light foot traffic and rooftop plant areas.
How long does commercial liquid roofing last? +
A correctly specified and applied liquid system typically lasts 20 to 25 years. Systems with thicker reinforcement or higher-grade coatings can perform beyond that. We’ll specify accordingly for your building and budget.
Are different grades of liquid roofing available? +
Yes. Systems vary in thickness, reinforcement and intended lifespan, and we’ll recommend the right specification for the building.
