To understand what a liquid roof is we need to understand the history of liquid roofing. Historical records indicate liquid roofing systems have been around for hundreds of years. Originally made up of natural bitumen combined with felt and straw to add reinforcement for a flexible solution due to bitumen’s brittle drying properties.
By the late 1950’s emulsion and acrylic liquid roofing systems were introduced to the market. These were great additions to the available liquid roofing systems. They could be used for both complete re-roofs and minor repairs. And could be applied by either a brush or a roller.
During the late 1960’s, styrene butadiene’s and unsaturated polyesters began to be used. The introduction of these liquid systems further developed the effectiveness of flat roof waterproofing.
Over time with advances in technology further improvements in liquid roofing were developed. And with this more systems came onto the market. In the 1980’s moisture cured polyurethane systems started to be used. This liquid roofing system can still be seen on sale today (some 35-years later).
Most of todays modern systems come from continuous improvement over the years. Many of today’s systems have made used advanced chemical engineering to allow for improved curing times and high flexibility to meet modern day requirements.
As with a lot of roofing systems, liquid roofing systems are completely seamless where, they are laid seams or laps.
A liquid roof has the added benefit of having working life that can exceed a lot of modern systems such as felt and mastic asphalt.
Nearly all liquid systems have a zero-service life and nearly all are self-terminating. The liquid system used for a liquid roof can also be used for zero falls roofs such as roof ponds and waterproofing steps.
Liquid waterproofing on flat roofs has not changed much since early applications.
With surface preparation to clean and reinforce angle changes or joints, reinforcement to the liquid or roll applied with chop stranded mat (CSM), fleece backed or a simple binder within the liquid itself. This enhances an already robust system.
With the age of technology machine spraying of the liquid waterproof coating for flat roofs is not an uncommon sight. This means larger areas can be spray applied with the capability of covering a surface area of 500m² in a single day.
As time goes on, liquid roofing systems are becoming increasingly popular both domestically and commercially. This is due to the ease of applying a liquid roofing system. With all this taken into consideration liquid roofing systems are here to stay.
