Gutters – Why are they high risk leak areas and how can RapidGutter help?

November 29th, 2021 by

Gutters are intended to protect your home from roof and basement leaks. Unfortunately, over time they get clogged and damaged, becoming a high-risk area for leaks. Despite this issue, the gutters are out of sight and easily forgotten by most homeowners. They take them for granted unless they need repair or replacement. Just being a proactive homeowner and by timely undergoing repair or maintenance, you can prevent costly issues down the road.   

First, let’s have a look at the reasons why gutters are high-risk leak areas in your home.

Why are gutters so important?

Gutters direct rain and melting snow or ice away from your home. With such, they prevent erosion and other water damages to the foundation and surrounding landscape. Gutters play a vital role in protecting your roof and basement from leaks, mold, rust, and foundation cracks. Such issues when not addressed promptly can leave you with the annoyance of costly repairs.

So, always try to select functional gutters and engage a reputable company to have them installed in your home. Properly functioning gutters are your first line of defence in keeping your home’s exterior in immaculate condition for years.  

What is the risk to gutters?

Leaves and debris can easily clog the gutters, but these are obvious and common issues. You can climb a ladder and clear the clogs without much trouble. But some issues are serious and can cause extensive problems for your roof drainage system.

When gutters don’t direct water safely away from the house, it can cause cracks in your foundation or the surrounding areas. Similarly, if you’re seeing standing water in gutters, you may have to call an expert to drain it. Otherwise, you can face problems like basement floods, leaks, and mold.

Gutters that are either damaged or are not properly installed will not serve the intended purpose. They need to be securely installed to drain water properly. So, if you’re seeing sagging, you need to secure them properly. Moreover, they are exposed to elements and can get cracked or rusted over time. So, if you see visible damage, you must call for repair immediately.     

Why RapidGutter is the best choice

RapidGutter is LRS’ unique waterproofing system for gutters, that not only prolongs the gutter’s life but also makes it leak-proof. It can be applied easily by a brush or roller, and it typically cures within 20 minutes. The coating is elastic and flexible to cope with most structural movement, unlike rigid systems.

RapidGutter is the perfect solution for all sorts of commercial and industrial projects. It is available in grey or standard black colour, but you can convey your colour requirements for a custom order.

The best thing about rapid gutter is that you don’t need a primer to install, and it adheres to most surfaces. There’s no need for any flashings, trims, or expensive detailing.

Time to save your gutter.

Gutters are high-risk leak areas in your home. An improper material or installation can put your home at risk of costly water damage. So, if you’re worried about your home or business becoming water damaged, RapidGutter is an ideal solution.

Liquid Waterproofing Systems | Why Are They Becoming More Popular?

November 1st, 2021 by
Liquid Waterproofing System
Liquid Waterproofing System (FastCoat)

There are multiple options when it comes to deciding how to waterproof your roof. In the past, people have used systems including single ply, EPDM, hot melt, and felt. However, the introduction of liquid waterproofing has come with many additional benefits.

Compared to other flat roofing systems, liquid waterproofing systems offer a unique and diverse option for roof waterproofing. Early systems have been used from as far back as 1800. However, more sophisticated technology allows the mixing of new formulas. As a result, improved systems are becoming more readily available at increasingly cost-effective prices.

In this article, we will take an in-depth look at why cold liquid applied waterproofing membranes are becoming increasingly popular for many roofing companies. We will also tell you which liquid system we would recommend using for different roofing projects.


Liquids are applied cold, eliminating the need and risk of naked flames and hot melt. This eliminates the potential of scolding yourself on the job, making your work safer for yourself and your colleagues.


Unlike other systems, in a lot of cases, there is no need to dismantle a roof and re-apply a new one. Liquids can be used over the top of existing roofs. This minimizes your time on site but also means you won’t be dealing with the excess material of the old roof. This makes liquid-applied products much more eco-friendly than other systems.

Time-Saving and Cost-Effective

With cure times as fast as 20-minutes you can finish domestic projects in a single day, reducing your own time on site as well as labour costs. Even more importantly, you to get to your next job sooner, therefore increasing the number of clients you can deal with in a year.

Tackle More Roofing Problems

Liquids can be applied much more freely than other products. For example, some roof repairs or a pitched roof can be quite challenging to completely waterproof, but with a spray-on liquid waterproofing system, it has never been easier.

It also makes it possible to securely waterproof gutters, an area that attributes to many leaks.

Improved Elasticity

Liquid waterproofing systems can offer between 200-600% elasticity to deal with most roof movements. As a result, the manufacturer can offer longer guarantees of up to 25 years, and will more than likely last much longer. This means you can be confident about your work and offer your clients the best of the best.

Product Recommendations

Now you know why roofing contractors are starting to use liquid systems, we suggest the following…

RapidRoof, a unique PMMA with high performance and rapid curing, is manufactured by LRS. Applied by brush or roller, RapidRoof is one of the fastest and most cost-effective waterproofing options for both commercial and residential projects.

FastCoat, also manufactured by LRS, is a single component liquid applied pure polyurethane. It provides fully bonded, tough and durable seamless waterproofing systems. FastCoat provides long performance life and exceptional UV resistance.

Elasto-Kote, manufactured by Karnak, is a SEB thermoplastic waterproof system designed specifically for application onto pitched roofs. It is ideal for metal, coated metal, concrete, and asbestos surfaces.

Flat Roof Overcoat System

May 28th, 2021 by

Once a flat roof starts to fail and cause water ingress to the structure below, you have two options:
1.) Rip up the failing roof and replace it with a new one.
2.) Use an overcoat system to coat the existing one, returning it to its watertight state.

Both ways of repairing a failing roof have their benefits and, in this blog, we will look at the benefits and costs associated with both ways of doing it.

Whichever way you prefer to deliver a roof that meets its function, having a cost-effective solution to repairing failing flat roofs in your arsenal can give you a much greater advantage when bidding for job opportunities.

Not all systems can be used to overcoat failing roofs. Some can only be applied to new build OSB boards, and so, you only have one option with these – strip and re-board. But there are systems on the market that are specifically designed to save you the time and effort of a full strip and re-board and enable you to complete jobs to the same level of quality, for a fraction of the cost.

Don’t believe me?

Read on…

Roof Strip and Re-Board

Have you been called out to a job to fix a failing roof and when you arrive, you just know that the timber structure below will be sodden? More than likely. With roofs that have degraded poorly, this can be easy to tell. And in this situation, there is typically only one option.

But some contractors believe this to be only one option to fix all failing flat roofs; strip and re-board.

If you expose the timber beneath the liquid coating and discover the timber to be sodden, you should complete a full job of ripping up the timber and re-laying new boards.

However, if the timber structure is still sound, you can save yourself the costly exercise of stripping timber boards and decking as well as the labour to complete the extra work.

If there was a more cost-effective solution, would it be worth looking at?

Roof Overcoat Systems

Certain liquid roofing systems are designed specifically to overcoat failing systems.

They have become a large part of the market due to the need for roofing contractors to offer a more cost-effective solution than entirely ripping up a roof.

When you’re tasked with fixing a roof you factor in the cost of labour and materials.

When a business or building owner is thinking of having their roof fixed, it’s not just the cost of materials and labour they need to think about. If as a roofing contractor you are going to fully strip their roof off, this means their business cannot function for that time. Whether that be a day, a few days, or even a few weeks; the cost of closing their business for any amount of time can very quickly add up!

So, for these customers, if you can offer a solution that negated the need to rip the roof off their building, do you think this might be a more attractive offer?

That’s where overcoating systems come into their own.

How to Know What Overcoating System is Best?

Now that we’ve established that having an overcoating system to offer your customers can be a massively beneficial tool to have in your arsenal. Next, it helps to know what overcoating system is best for different applications.

Depending on what the failing roof substrate you’re looking to overcoat is, there will be a range of systems suitable for this application. Let’s have a look at a few of these here and determine the best overcoating option.

Liquid Coatings, GRP, Single Ply

One of the best overcoating systems on the market for these substrates is RapidRoof. A high-performance, fast curing PMMA system that delivers excellent bonding properties, flexibility, and a seamless finish.

Felt, Asphalt

Overcoating felt and asphalt can bring up additional challenges and you will need a tried and tested system if you are looking to overcoat this type of substrate. The best system for this on the market that we know of is FastCoat, a pure polyurethane (PU) cold liquid applied coating ideal for this type of project.

Metal, Concrete, EPDM, Asbestos

You will struggle to find a system on that market suitable to cover some of these substrates. EPDM can bring up several problems, and when it comes to asbestos you need to be extremely careful. We only know of one system that can overcoat all these as well as safely encapsulate asbestos: Elasto-Kote. A SEBS elastomeric polymer that can be spray applied to make large roofing projects simpler.

Top 5 Best Cold Liquid Applied Waterproofing Systems

April 15th, 2021 by

Cold Liquid Applied Waterproofing Systems

Compared to other flat and pitched roofing systems, cold liquid applied roof waterproofing systems offer a unique and diverse option. Early systems have been used from as far back as 1800. As more sophisticated technology allows the mixing of new formulas; new and improved systems are becoming more readily available at increasingly cost-effective prices.

In this article, we will take an in-depth look at five of the best types of cold liquid applied waterproofing membranes available on the market today, and the best application for their specific formulas.

Knowing which system to use is not always easy. This will shed some light on which liquid waterproofing membranes are best for different specifications and roof substrates. We will also list some waterproofing systems available in each category and the specific benefits of these systems.

Whether your buying criteria are for certification, speed of application, cure time, or cost; liquid waterproofing has something to offer everyone. If you’re interested, read on to find out more.

Polymethyl Methacrylate (PMMA)

PMMA’s were first developed in Germany in the first half of the 1900s and were brought to the market only a few years later. PMMAs have rapid curing qualities, they are very flexible yet extremely tough and robust. This has made it a very successful product for many applications in the construction industry.

PMMA is typically a two-component system, comprising resin and catalyst. The use of the catalyst or hardener in this system causes a chemical reaction creating heat which cures the product at a rapid rate, even at temperatures down to 0oC or lower.

Roofing contractors will mix the two components on-site and apply the complete system immediately, ensuring they have enough time to evenly lay the product to its correct specification before it is cured.  

PMMA’s are ideal for roof waterproofing projects where access is restricted and there are time restraints. Because it is a flexible, durable, hard-wearing, and rapid curing roof waterproofing system.

By far the most effective PMMA waterproofing system on the market in our opinion is RapidRoof Pro. A high-performance, rapid curing, cold liquid applied flat roof waterproofing system with a typical curing time of 20 minutes. This system has been rigorously tested, has over 200% elasticity, and will cure down to 0oC making it suitable for year-round application.

Polyurethane (PU)

Cold Liquid Applied Waterproofing Systems

One of the most popular and widely used cold liquid applied waterproofing systems on the market today are polyurethanes, or PU’s as they are often abbreviated. PUs are some of the most versatile systems as they are used for a multitude of applications including roofs, gutters, and walkways. Due to their durability, they are very suitable and are often used for high foot traffic areas – further cementing their versatility.

Typically, a two-part system contains a double waterproofing layer and a glass fibre reinforcement matting. PU’s have become the preferred choice compared to some other liquid-applied waterproofing systems.

The most versatile and effective polyurethane we believe to be on the market is Liquid Roofing Systems’ FastCoat Pro. This is a single component, fully reinforced, pure polyurethane system that offers an exceptional long-term solution to flat roof waterproofing. FastCoat Pro also offers an additional traffic coating for use on balconies and walkways.

Unlike many alternatives, FastCoat Pro can offer substantial reductions in application time. This helps to save significant amounts of project costs and reduces disruption.


Rubber polymers have seen many advancements since their development more than 50 years ago. SEBS polymer waterproofing systems are used in the development and refurbishment of both metal and asbestos flat and pitched roofs.

Once applied, this system produces an elastomeric roof coating that is long-lasting and excellent protection against water ponding and ingress. Due to its excellent water-resistant properties, it is often specified for flat roofs and roofs that have a lot of standing water.

Its elasticity allows the system to cope with the expansion and contraction that occurs in typical roof movement and makes it a very suitable waterproofing solution for large-scale industrial or commercial roofs.

Many rubber polymer systems are single component and self-priming making them ideal for large-scale projects that are time-sensitive.

The most effective and versatile SEBS waterproofing system on the market in our opinion is Karnak’s Elasto-Kote. It is a thermoplastic system specifically designed to be applied onto flat and pitched industrial roofs. It offers an exceptionally high-performing elastomeric system with a built-in rust inhibitor, 85% solar reflection, and 650% elongation.

Cold Liquid Applied Bitumen

Cold Liquid Applied Waterproofing Systems

Since the early 1800s, bitumen has been used as a waterproofing solution where natural bitumen was mixed with other natural materials and fibres. Modern technology has come in leaps and bounds since its first use. Since then, bitumen roofing systems have become one of the most diverse and widely used systems on the market today. Thermal expansion in materials has contributed to the considerable popularity of these systems, compared to other construction materials such as concrete or steel.

Bitumen roofing systems come in many forms on today’s market, such as felt, asphalt, and rubberised bitumen. The latter, cold liquid applied bitumen is the type of system we will be looking at in more detail in this section of the article. Whether you need a full roof coating system, underground tanking, or a simple roof leak repair product; hopefully here we will have an answer to your problem.

LiquidRubber is LRS’ highly advanced eco-friendly polymer. It comes in two forms as it can be used both as a hand roll-applied system, but possibly more interestingly; LiquidRubber Instant Set is a spray-applied system used to coat large scale industrial roofs in a fraction of the time.

LiquiTank is a variation of the LiquidRubber system. A high-performing waterproofing membrane designed specifically for tanking, structural and underground waterproofing.

Repair Systems

Most chemical compositions and formulas also have repair systems in their range. Each of these is suitable to repair different size and severity of roof damage. We think it best to add a section for roof repair systems. Here we can determine which are most suitable for different repair needs.

Typical roof repair jobs vary from patch repairs, crack repairs, part, and full encapsulations. Depending on if there is a leak, standing water on the roof, or the roof substrate that needs repairing; certain repair systems will work better.

For example, Karnak 19 Ultra is an extremely impressive repair system. It describes itself as the next generation of bituminous elastomeric flashing cement. 19-Ultra is ideal for use on roofs that have a lot of water as not only will it create an instant watertight seal, but it can also actually be applied underwater.

RapidRepair is a PMMA-based repair system that contains premixed glass fibres, which increase its strength and flexibility. providing greater strength and bridging properties, allowing the faster and more effective application to acute areas of damage requiring repair. This repair system is ideal for repairing cracks or split surfaces on flat, dry roofs.

Karna-Flex is an elastomeric, thermoplastic rubber sealant formulated to be used on properly prepared metal, concrete, spray polyurethane foam, and plywood roof substrates. Its ease of application, superior adhesion, elasticity, and durability make Karna-Flex an ideal repair sealant. Available in a brush mastic or caulking cartridge.

What Is Asbestos? | Why Is It Dangerous?

February 26th, 2021 by

What is Asbestos & Asbestos Encapsulation?

Asbestos is a set of six naturally occurring silicate minerals, which all have in common their eponymous asbestiform habit. For instance, their long, thin fibrous crystals, with each visible fibre. They are composed of millions of microscopic “fibrils” that can be released by abrasion and other processes. Asbestos encapsulation means coating these fibres to ensure none are released into the air.

A staggering 5000 deaths each year are linked to asbestos. In homes built before 2000, it is still common to find.

Why is asbestos dangerous?

If asbestos-containing materials are disturbed or damaged, asbestos fibres are released into the air. This can cause severe diseases if inhaled. That said, these diseases will not affect you immediately; they often take a long time to develop. However, once diagnosed, it is often too late to do anything. This is why you must protect yourself now.

This information was taken from (Health & Safety Executive).

Asbestos encapsulation

On the other hand, the good news is that asbestos roofs can be encapsulated using a suitable coating system. This saves the problem of having to get specialists in to clean or remove the existing asbestos.

Elasto-Kote is an ideal solution for this type of roof as it is used to encapsulate asbestos, and waterproof it at the same time.

LRS have roofing systems suitable for asbestos encapsulating. Contact our friendly team of industry specialists today to discuss in more detail, on 01948 841 877. Alternatively, email [email protected].

Sheet Metal Roof Repairs | Commercial and Industrial Roofing

February 8th, 2021 by

Why Use Metal Roofs?

In this article, we will look at some of the benefits of using sheet metal roofing, the problems that can arise, and some easy sheet metal roof repairs for when they do.

Metal is strong, robust, and flexible, which is why it is commonly used in commercial and industrial roofing. It is a lightweight material which offers roof waterproofing and longevity on large scale buildings and structures which need to be kept watertight. As well as that there are several cost-effective solutions for when you do need sheet metal roof repairs.

Due to its lightweight and easy installation, sheet metal roofing is also a very cost-effective roof when compared to tiles, slate, or concrete. This means you can cover a larger area in a shorter time and for less cost. 

Metal Roof Problems

Sheet Metal Roof Repairs

Metal roof sheets are covered with a plastic coating such as plastisol when they are manufactured. This helps prevent the metal from becoming corroded over time. However, when being cut to size in the factory, this often leaves an exposed metal edge which when exposed to oxygen, will begin to corrode the metal and is often the area where roofing problems will develop. Water will begin to exacerbate the problem and cause the coating to peel off from the metal, leading to further problems and increased areas of damage and potential leaking.

If your roof is older than 10 years and has been left untreated then it is highly likely that rust and corrosion will have begun to set in around your cut edges, if it has not already developed further and caused leaking or internal damage from water ingress.   

Overcoating Solutions

Sheet Metal Roof Repairs

I do not need to tell you how expensive full roof replacements are, so if you can offer a solution which re-coats the old roof – instead of fully replacing it – saving you time and money, minimizing disruption to the business below, and increasing your efficiency on site – this is typically the preferable choice for most roof contractors and building owners/managers.

The next problem comes from which overcoating system to choose, and why. With many systems on the market making false promises or claiming to offer flexibility, long life spans and cost-effective solutions – I urge you to take a further look into each system and the manufacturer’s reputability before committing yourself to anyone or the other.

The main benefits to look for when deciding on a liquid roofing system are expressed in the following:


No one wants to be dealing with products or contractors whose roofs only last 2-5 years before needing replacement, so make sure you use a reputable product that has a guarantee of 10 – 20+ years (remember there is a difference between a life expectancy and a guarantee), like Karnak’s Elasto-Kote systems which have a 20-year guarantee.

Time Saving

The quicker you can lay the product the quicker you can finish the job. Elasto-Kote can be spray applied, which means you can apply up to 5X faster than when using a roller or brush. This means your time is therefore worth more. And just maybe you can finish work on time this week.

Cost Effective

Ensure that the system you are using is the most cost-effective for your needs. How much does it cost to install per m2 when considering the cost of material, labour costs, and expenses? Ensure the product is applied most cost-effectively, using a simple spray application.

Minimal Fuss

Roof preparation, set-up, and cleaning are all time-consuming tasks to be factored into the overall cost of roof installation. Minimising fuss around these tasks means that your time is worth more, you are not spending half the day fussing. Elasto-Kote reduces all of this fussing as it is simple to set up, easy to use and quick to apply. This gives you the ideal solution for when you need to complete sheet metal roof repairs.

Ongoing Support

What do you do when you come to an issue on-site? Figure it out yourself? Check the manufacturer’s instruction on their website? Doing all this will waste your time and not always give you the answer you’re looking for.

Or just make one quick call to on-hand technical support and have an answer there and then. Which would you prefer?

At Liquid Roofing Systems, we pride ourselves on our quality products as well as our first-class customer service. Our friendly, supportive technical advisors are always available to support your needs. Monday to Friday, 9 am to 5 pm call 01948 841 879. So, you can stop worrying about roofing problems and start delivering your customers solutions to their problems.
