The Benefits (And Downsides) Of Liquid Roofing Systems


We are often asked about liquid roofing systems – our clients want to know if it’s a good option for protecting and repairing their industrial roofs. As highly experienced contractors we like to share our knowledge to help people understand the processes a little more, so they can make an informed decision about their property maintenance. 

So if you have a roof that needs repair, you have a new roof that you want to protect or you’re just curious about the ways you can reduce your ongoing maintenance costs, this blog is for you.

Read on to find out what liquid roofing systems are, how they can extend your roof’s lifespan for up to 30 years and if there are any downsides to the process…

What Are Liquid Roofing Systems?

Well, the name gives it away a little – liquid roofing is quite literally a liquid substance that is applied to your roof to prolong its lifespan. Liquid roofing systems use a selection of materials to create a watertight barrier on your roof – different systems have different strengths and weaknesses. 

So, in order for you to know which is the right choice for you, let’s go into more detail.

The use of protective coatings to preserve a surface dates back to ancient times when bitumen was used to line canoes and boats to keep them watertight. This practice continued through the centuries with substances such as tar or pitch used to seal the wooden decks of ships – so the concept of liquid roofing is far from a new one.

But it’s only when you pair the process with the latest developments in waterproofing technology that you see just how far liquid roofing has come.

Nowadays, the substances used to coat your roof have been carefully formulated to handle whatever the weather throws at it – from the coldest frost to the hottest sun.

There are several types of liquid roofing that we can use, depending on the type of roof you have and the problems you’re experiencing.

Polymer Modified Bitumen

As we’ve discovered, bitumen has been used to waterproof vessels for an incredibly long time – and as the saying goes ‘if it ain’t broke, don’t fix it’. Except in this case, it was enhanced. 

For use on your roof, bitumen is modified with polymers to increase its durability and flexibility once dry.

Polyurethane-Based Systems

Polyurethane liquid roofing systems are one of the strongest roof coatings on the market. Its long-lasting durability, coupled with its ability to reflect UV rays makes it a good choice for large roofs that are in direct sunlight.

Polyester-Based Systems

Polyester based liquid roofing systems have the longest life expectancy of all the options, lasting up to 30 years. Some types use fibreglass to reinforce the polyester resin, while others use a polyester fleece (similar to the kind you wear to keep the chill away!) which absorbs the resin to become a uniform and unyielding membrane.

What Are Liquid Roofing Systems Used For?

The primary purpose of liquid roofing is to provide a waterproof coating to your roof. In doing this, your roof is protected against the most damaging weather – rain. 

Any type of liquid roofing system means that any rainwater easily runs off your roof, rather than pooling where it can start to seep through the layers of roofing membrane.In addition to this, at GI Sykes, our liquid roofing systems provide an excellent option for repairing minor cracks, rips and tears.


What Are The Benefits Of Liquid Roofing Systems?

There are plenty of benefits to having a liquid roofing system installed. They key benefits are:

Waterproofing Your Roof

An obvious benefit, we know. A liquid roofing system means that you don’t have to worry about standing water on your roof causing problems.

Your Roof Looks Great

Thanks to its application process, liquid roofing looks neat, smooth and seamless. It helps to give your building a tidy and well-cared for finish.

Seamless Repair

Our liquid roofing systems mean that any cracks or tears to your roof are sealed with a fully bonded waterproof coating. It’s a simple but very effective repair option.

A Roof That Reflects UV Rays

Liquid roofing can reflect UV rays, helping to reduce the temperature within your building. Some liquid roofing systems do this better than others, so if you think you need a cooler environment in the summer, we’d be happy to advise you on the most suitable options.

A Longer Lasting Roof

Liquid roofing adds a protective layer to your roof which helps to extend its lifespan considerably. Not only are you saving thousands in replacement costs, you’re also reducing the environmental impact of adding more waste to landfill.

Less Maintenance For Your Roof

And since your roof is nicely protected, you will find you have less problems with it. Leaks will be a thing of the past, so your roofing maintenance will be much reduced,

Super Fast Installation

Liquid roofing takes very little time to install – some projects take just one day to complete. It’s also non-disruptive so you can carry on about your day while your roof is taken care of.

What Are The Drawbacks?

The list of drawbacks to investing in a liquid roofing system is a one. There aren’t any. 

However, these are the things we think you should consider if you are planning on using a liquid roofing system on your building.

Poor Application Looks Bad

Imagine the Mona Lisa. Carefully placed brushstrokes, all coming together to create a work of art. Now picture a toddler’s painting. Streaks and blobs all over. While cute, it’s not the finesse you want hanging in a gallery (we do love to see them on the fridge though!).

The application of liquid roofing is something that’s best left to the experts – otherwise you might end up with a streaky, blobby mess.

Hazardous When Wet
Due to its waterproof nature, liquid roofing is incredibly slippery when it is wet. The only people who should be on your roof are trained professionals with the right equipment. 

You Need A Reminder

Liquid roofing is so effective, you may forget to book your regular roofing maintenance check. Even though you may not see any problems, it’s still advisable to have routine inspections.
