Liquid Roofing Systems

Liquid roofing systems are applied in a wide vary of applications and system build ups. Emulsion and acrylic systems were available for coating during the 1950s and were installed as a repair and full systems by roller and brushes. As time went on the liquid roof systems improved and by the 1980s moisture cured polyurethane came into play and greatly improved in performance. A polyurethane coating system is a layer (type of polymer) that is applied and protects base material from weathering, abrasion and corrosion. The system normally is a single or a twin pack that may have fleece or fibre glass matting and is installed ‘Wet on wet’. As this product has progressed the liquid has now become odour free, and is ideal for projects on offices, schools, hospitals and other sensitive areas.

GRP or glass reinforced plastic was first developed in the late 1930s and If extremely strong and is non-corrosive. This roof system is ideal for smaller projects (under 60m²) and can be laid directly on OSB board or can now be used as an overlay system. With the resin/ matting/ resin has been applied, a topcoat is applied, and the finish looks like a moulded plastic roof finish.

PMMA (Polymethyl Methacrylate) systems for roofing are probably the most widely applied to present date due to its rapid curing and can be applied in foot trafficked areas. It is highly flexible, hard weaning and with a track record spanning back to the 1930s this liquid roof system has stood the test of time.

Thermoplastic block Copolymers (SEBs) has been around since the 1950s, SEBS polymers are applied to profiled sheets and metal, bitumen, single-ply plastics and many other surfaces. The product can cope with extreme expansion and contraction as with the other systems, this has a reinforcement layer and adds to the strength of the product.

Cold applied Bitumen were used in the 1780s-1800s and was combined with straw or jute to provide a waterproof solution. With time introduction of polymers (Rubber based) these have greatly improved the flexibility of the product where old bitumen roofs were a 5-10year system. As roofs experiences thermal change and hotter summers with colder winters, it led to expansion and contraction movement. This roof system can provide a 20-year guarantee quite comfortably.

Why Choose a Liquid Roofing System?

Liquid roofing has many advantages. It’s main features and benefits are it is waterproof, cost-effective, perfect for complex cetailing and can be cold applied. Liquid roofing can be applied in a variety of different applications of all shapes and sizes. This include flat roofs, pitched and dome shaped roofs. Upon application dependent on the temperature the roof with a liquid coating becomes waterproof within 2 hours and in many cases immediately.

Benefits of Choosing a Liquid Roofing System

Cold Applied: No Heat or Flame. This eliminates both the inconvenience and hazards which present themselves with hot works. Another benefit is buildings can be occupied and operational throughout the installation of a liquid roofing system.

Usable at Low Temperatures: Liquid Roofing can be applied all year round if the temperature is above 0℃.

Perfect for Complex Detailing: Liquid Roofing Systems can fill every tiny detail of a roof which it is applied to. This ability sets it apart from other membranes.

Easy Maintenance: Liquid Roofing Systems can be easily maintained and boast excellent through life costs. As it is a liquid system repair work can be carried out without any disruption to the inhabitants of the building being repaired. Obviously, this is a huge bonus in commercial properties as no downtime will have to be endured.

Water Repellent on Application: Some of the Liquid Roofing Solutions we provide become weatherproof immediately upon application. Others take up to 2 hours. These times can vary in extreme temperatures.

Vapour Permeable: Liquid Roofing’s vapour permeability allows moisture vapour within the building it covers to escape. This makes a Liquid Roofing System a great solution for building which have historically suffered from water ingress.

Excellent Elasticity and Tensile Strength: Can withstand natural roof movements without splitting or shearing.

Cost Effective Wet on Wet System: Liquid membranes are a durable waterproofing option. Their lifetime can be between 5 and 30 years, depending on their purpose and the environment they are applied in. This makes liquid roofing a durable waterproofing solution. Due to it being a liquid solution it also has lower maintenance and repair costs.
