The History of Roofs

Man has been around for a long time now and over the years we have endured a great deal of development. It’s strange to think that in such a technology driven world we didn’t even have a public supply of electricity 136 years ago! In fact, the very first telephone call between Alexander Graham Bell and his assistant took place 5 years before we even had public electricity in 1876! Man’s tendency to build and create began a long time ago and here at Valent Roofing, we’re going to go over the history of roofs…

  • Cavemen are said to have covered their structures with earth and plants and whilst they were not particularly waterproof, they provided very effective insulation against the elements.


  • In around 735 AD, thatched roofs, which is a roof built with materials such as straw, were created. Around 300 years later, wood shingles were introduced.


  • It has been discovered that the first known use of clay tiles occurred around 5,000 years ago in China and in 100 BC, the Romans brought variations of it to England.


  • Due to the easy spread of fire, King John of England issued a law in the 12th century which stated that all London inhabitants had to replace thatch roofing with clay tiles.


  • With industrialisation taking hold, clay roofing was industrially produced at the beginning of the 19th 100 years passed and concrete roof tiles were used for the first time too. In the early 1900’s, a pigment was added to the concrete to help it appear more aesthetically pleasing and in the 1970’s Germany began to develop green roof systems.


  • Over the years, we have come a long way in terms of roof developments and advances in glass, polymer and smog absorption means that the door is wide open for future progress. It is expected that environmentally friendly roofs will be the next big trend.

Advantages and Disadvantages Metal Roofing

Here at Valent Roofing, we are the people to speak to when it comes to industrial roof related enquiries. After all, the team here are the experts and our experienced staff will be able to answer any questions you may have. In this blog, we’re going to place the focus on metal roofing and let our readers know a few pros and cons of this type of material…


  • When they are correctly installed, a metal roof has a fairly high life expectancy. In fact, some say they can even last as long as a house itself before it will need replacing. Being able to withstand high winds, heavy snowfall and water sneaking into the property is an obvious bonus when it comes to a lifelong investment.


  • Many people presume that because the roofing is made from metal that it will be very heavy however it is a fairly lightweight material, especially when compared to tile.


  • The biggest drawback of a metal roof is the initial upfront cost, however many buyers tend to consider it an investment for the future. Metal roofs are especially beneficial if you have no plans to move house in the future or are operating a business inside an industrial building and want to invest in the building itself.

If you’ve got any further questions regarding metal roofing or simply want us to ease a few concerns, get in contact with the team here at Valent Roofing. As the best of the best in the industrial roofing industry, there’s no concern that we can’t fix!

The Lowdown on Flat to Pitched Roof Conversions

Here at Valent Roofing, we offer a range of different services at competitive rates whilst also ensuring that our customers get the best work possible. One of the services we offer is a flat to pitched roof conversion. Sometimes it is difficult to decide whether a roof conversion is for you so the team here at Valent Roofing have done the job for you! Here is the lowdown on this type of roof conversion…

Why have your roof converted?

There are usually many issues associated with owning a flat roof and, most of the time, this is the reason why many people will opt for a pitched roof conversion. Until recently, the most popular materials used on flat roofing was tar, gravel and asphalt. In fact, some companies still recommend using asphalt- however this material is known to dry and crack, causing issues before the build is even one year old. In addition to this, a badly installed flat roof means that customers are left dealing with constant repairs. A roof conversion offers the opportunity to wave goodbye these issues once and for all.

Is a roof conversion for you?

Sometimes is not as easy as jumping straight into a roof conversion as we have to be sensible and weigh up the pros and cons. These days roofing materials have advanced with the introduction of flat roofing membranes like TPO. It is said that these can be just as water tight as a pitched roof at 3 to 4 times less that the cost of a conversion. Despite this, many people still complain that their flat roof does not seem structurally sound and frequently hear the sounds of the wooden frames creaking under the weight of heavy rain and snowfall. If you face these issues, a pitched roof conversion could be what you are looking for.

Pros of a flat to pitched roof conversion

  • A pitched roof is aesthetically pleasing and has a very attractive look to it. When money isn’t an issue, you can make the most of your pitched roof conversion.
  • Converting your roof means that insulation is easier and more effective as insulating a pitched roof is said to be more economical.
  • Vapor drive occurs in flat roofs and causes moisture to puddle on the underside. This does not occur with a pitched roof because an airflow pattern can be created easily.
  • More storage space is available with a pitched roof, especially if you can form an area in-between the old flat roof and the new pitched roof.
  • Pitched roofs are said to last around 20-25 years, which is roughly 40% longer than a flat roof meaning that they are a worthwhile investment for the future.

Why You Should Hire Professionals To Remove Asbestos

When it comes to replacing an old existing roof, your primary concern is probably going to be what the new roof is going to look like and how much it’s going to cost. This is understandable, as both are two very important factors when hiring a professional roofing company, and so it’s no surprise that most people forget all about the asbestos.

There are some people, however, that are fully aware of the asbestos’ presence, and determine themselves to take care of the issue themselves. Asbestos has to be removed before a new roof can be installed, and some property owners attempt to get rid of it before the professionals come in. This can be a very bad idea, as it’s no secret that asbestos can be very bad for your health.

Health Concerns

By attempting to tackle any asbestos yourself, you’ll be running the risk of inhaling fibres that can prove extremely damaging to your health. Mesothelioma, lung cancer and pleural thickening are just a few examples of how asbestos can be cause for concern. Of course, people that develop these diseases are generally people that have been exposed to asbestos for long periods of time, however you’re bound to be better off letting the experts handle it just in case!

What The Professionals Bring

By bringing in a reliable asbestos removal company, you’ll be ensuring that it’s been removed efficiently. Ultimately, their level of expertise will mean that the asbestos is taken care of in a timely manner, as well as that it’s been completely eradicated. Asbestos is notoriously difficult to identify unless you know what you’re doing, and it can prove to be even harder to then actually get rid of it. Well, a professional company will know exactly how to get rid of any asbestos in your roofing, and will ultimately be able to create a safer environment. Through their access to top of the range equipment and their all-round industry knowledge, asbestos removalists are becoming an absolute necessity.

Here at Valent Roofing, we provide a range of industrial roofing services, and can also remove any asbestos when we are recladding an existing roof. For any further information on the services that we provide, please don’t hesitate to contact our dedicated team.

3 Big Benefits of Rain Screen Cladding

When it comes to designing a new building, the importance of your roofing cannot be overestimated- particularly when it comes to a commercial premises. Your roof will constantly be exposed to the elements and is actually the most vulnerable part of your premises, meaning that it’s important your roofing is constructed to a high standard.

Fortunately, here at Valent Roofing we provide a wide range of excellent roofing services that are dedicated to ensuring that our clients are given a top quality roof. One such service is our rain screen cladding, which can be successfully applied to a brand new build or on top of cladding that has already been installed.

Rain screen cladding provides a number of benefits, making it an essential part of many industrial roof installations, and we’re here to run you through 3 big ways it could be beneficial to you.

  • Improved Insulation

At this time of year, the cold weather can really become a nuisance, and many people will find themselves constantly reaching for a thick jumper or gloves due to the lack of warmth. For large industrial properties, attempting to keep the interior warm will soon rack up large energy bills and will prove to be very expensive, and so many businesses will endeavour to battle through the cold.


However, rain screen cladding provides a certain amount of thermal insulation, meaning that heat finds it much harder to escape and will eventually create a warm, toasty environment. This will ultimately make it more comfortable to spend time in the structure and ensure that you’re kept warmer this winter!


  • Maintenance

Perhaps the biggest advantage to rain screen cladding is the fact that it will reduce the amount of maintenance work needed on your roof. As it protects the other roofing materials from the bombardment of wind, rain and even snow, rain screen cladding ensures that your roof is kept safe. Due to this added protection, you’ll find that you no longer have to keep calling out for maintenance- which will obviously save you time and money in the long run!


  • Long Term Investment

By reading the previous two rain screen cladding benefits, this last one should be fairly self-explanatory. Of course, the installation of rain screen cladding will incur an upfront cost, however you need to take into account just how much money it will save you in the long run. With the improved insulation and the lack of required maintenance, this means that rain screen cladding will be an incredible investment that will most certainly pay dividends!

Valent Roofing Gearing Up For A Busy Christmas!

As unbelievable as it may sound, November is already coming to an end and that means that Christmas is just a few weeks away. Brace yourselves for a month full of mince pies, cheesy songs and tear-jerking adverts, because it’s almost time to get into that festive spirit once again. At this time of year, things can get a little quiet here in the roofing industry; however, this year we are in the fortunate position of having plenty to be getting on with.

Here at Valent Roofing, we provide a wide range of excellent services that are all designed to offer clients an efficient roofing solution. From rain cladding systems to the installation of industrial roofing, our experts have experience working on a wealth of different projects, and it’s good to see that word of our excellent service seems to be spreading.

As we carry on towards the inevitable arrival of Christmas and New Year, we’re finding ourselves to be very busy here, and we’re working on a couple of really exciting projects that we thought you’d like to hear a little bit about.

Block 15, Alderley Edge

It was back in January when planning permission was finally granted for the redevelopment of a group of buildings at Alderley Park over in Alderley Edge. These buildings were previously known as the Central Toxicology Laboratories (CTL), but they haven’t been used for over ten years- and are now simply known as Block 15. And as you’ve probably guessed, Valent Roofing have been brought on to handle some of the redevelopment!

The renovation is geared towards creating more offices, laboratories and manufacturing facilities, and we’re sure that locals are thrilled to see that something is finally happening with the buildings. We’ve  been busy designing and installing a brand new roof to go on top of the new steel frame building since August, and we expect the work to be done by the end of January/start of February. Keep an eye out for the finished project, as it’s going to be a perfect example of the high quality work that we are able to provide!

Today’s Community Church, Wigan

Another project that we’re expecting to have done by the end of January is our work on Today’s Community Church in Wigan. The project involves the building of a brand new auditorium, which will end the area’s 30-year-wait for a four figure seater concert hall. Today’s Church have first refusal on the brand new arena, but it’s expected to be used for a variety of uses- such as different events, meetings and conferences.

The project has involved the building of a new steel frame structure, and we at Valent Roofing are going to be supplying the roof. Although our work will be done by the end of January, the auditorium itself won’t open for another couple of months after that- but it’s going to be a grand opening night at the end of March, and we’re very excited to be part of such a big project.


These are just a couple of examples of the industrial roofing work we’re going to be doing over the next couple of months, and so keep an eye on our blog for any further updates as to what we’ve been up to!

What Are The Advantages of Industrial Cladding?

Industrial cladding is one of the most important aspects of the building or renovation process for industrial properties. While the need for this particular method of external reinforcement is generally less immediately evident than the need for adequate industrial roofing, for example, the truth is adequate industrial cladding can play just as important a role in ensuring the longevity and protection of an industrial property.

This is why industrial roofing and cladding experts, such as the ones working for Valent Roofing, tend to advise their customers to devote as much attention to their cladding as they generally do to their roofing. It is essential that factory owners and industrial property managers are aware of how best to go about choosing and installing industrial cladding in their newly-built or refurbished buildings; and yet, more often than not, specialists working for companies such as Valent Roofing find these types of professionals have but a passing notion of the importance of cladding to the longevity and protection of an industrial property.

Indeed, one of the most frequent questions the team here at Valent Roofing gets asked by both existing and prospective clients has to do precisely with the role cladding plays in an industrial building, and the reasons why specialists recommend it be installed in such a facility. That is why we have taken it upon ourselves to dedicate this month’s blog post to answering that question. The lines below will go over the benefits carefully chosen and adequately installed industrial cladding can have in terms of protecting an industrial property from external factors and prolonging its lifespan.

What are the advantages of industrial cladding, then? The paragraphs below hold the answer!

Increased Longevity

The first way in which industrial cladding can impact an industrial building or facility is by prolonging its longevity and lifespan best site.

Being more often than not located on the outskirts of large towns or in isolated areas in the countryside, industrial buildings are even more subject to wear and tear deriving from external factors than commercial or residential properties located within urban areas. The average industrial building is subject to such damaging external agents as weather conditions and wildlife, and with materials such as brick or stone being quite easy to damage, many industrial buildings begin to appear run-down only a few years into their lifespan.

Industrial cladding is a good way of preventing, or at the very least minimising, this effect. The characteristics innate to most of the common types of cladding available on the market ensure they retain a relatively sleek, well-kept appearance even over the course of time, and as a result, contribute to make any building they are applied to appear in better condition than it might have done without outward cladding.

The impact industrial cladding has on the outside of a building is, however, more than simply aesthetic. As noted above, certain types of cladding panels actively protect the walls of a building from elemental wear and tear, as well as any other damaging agents, effectively ensuring the premises enjoy a longer lifespan. Not only that, cladding panels are easier to maintain and care for than traditional building materials, which can also positively impact the longevity of industrial premises.

It is, therefore, easy to see how the installation of adequate industrial cladding can impact the durability and lifespan of the exterior of an industrial building; however, this method also has considerable impact on the inner area of a property, and that impact will be explored in the lines below.

Added Protection

Even more so than for increasing the longevity and durability of the outside walls of a factory or industrial installation, industrial cladding is renowned for the protection it offers to the inside of this type of building.

As noted above, industrial buildings tend to be set in out-of-the-way areas, and as such, exposed to the elements, as well as a number of other external damaging agents. These have an impact not only on the outside, as described above, but also on the inside, namely because repeated wear and tear deriving from atmospheric conditions or wildlife inevitably leads to such issues as breaches, infiltrations and damages to the structural integrity of the building.

The reason industrial cladding is considered such an important asset to these types of buildings is because it can prevent this type of issue. Appropriate cladding, carefully selected to cope with the circumstances and conditions each building faces, can offer an additional layer of protection and insulation to a building, therefore reducing the risk of breaching or infiltrations occurring, and thus also the risk of damage to the interior of the building.

This is particularly important insofar as the interior areas of industrial premises tend to house items of heavy machinery, highly specialised appliances and often technologically advanced devices, all of which are vulnerable to infiltrations, mould, or any other damaging agents resulting from wear and tear to the outside walls of the building. Industrial cladding thus plays a major role within the construction or renovation process, often spelling the difference between a durable, safe industrial building and one which will rapidly become run-down and prone to infiltrations or structural damage. This, in turn, constitutes another reason why factory managers and industrial real estate owners should pay particular attention to this aspect when building or renovating their property.


The lines above have sought to give an overview of the many ways in which industrial cladding can help preserve the outer condition and structural integrity of factory buildings and premises, and of the advantages of considering this option when building or renovating industrial property.

What are the advantages of industrial cladding, then? As the article above has demonstrated, this type of material is beneficial not only from an aesthetic perspective, but most importantly, where insulation and protection of the structure itself are concerned. In other words, not only will industrial cladding allow a building to look better for longer, it will also actively contribute to protect its structure from the effects of the elements, and minimise the risk of leaks, cracks and other structural damage deriving from natural wear and tear.

When those functions are taken into account, it becomes easy to see why industrial cladding is worth investing in; we can only hope this article has contributed to make more industrial property managers aware of the benefits this type of technique can bring to their premises, and motivated them to invest in it!

The Different Types of Industrial Roofing Sheets

The Different Types of Industrial Roofing Sheets

Industrial roofing is one of the key components of any industrial building. Essential in shielding the building and its contents from the elements, as well as occasional hazards posed by flying animals or other airborne fouling agents, the roof is an element which must definitely be given the appropriate amount of importance and consideration when first building or renovating an industrial building.

Sadly, many industrial property owners and managers are not aware of just how important this element is, and tend to neglect or rush their choice of industrial roofing. This, in turn, results in the roofing sheet inevitably damaging, bringing about the need for additional roof repair, and the added expenditures that brings about.

As such, it should be evident why it is important for industrial property owners to know how to pick the right type of industrial roofing for their factory or plant; and a good place to start when attempting to ascertain which might be the right type of roof for any given property is to become aware of the different types of industrial roofing sheets available on the market, and the different characteristics each one possesses.

It is in that spirit that the present article attempts to make potential customers aware of precisely that factor. The paragraphs below will aim to introduce less knowledgeable customers to the different types of industrial roofing sheets they can choose for their factory or plant, so as to help them make an informed decision when making a choice of covering for their property.

EPDM Rubber Roofing

Of all the different types of industrial roofing sheets available on the market, EPDM rubber is one of the most popular and widespread, having been used as the covering for factories the world over for over four decades. Ethylene propylene diene monomer, the type of synthetic rubber used in this type of roofing, possesses several traits which make it a firm favourite among contractors and factory managers alike, and which have earned it its status as the most popular type of industrial roof covering in modern western society.

Perhaps the main trait making EPDM rubber roofs particularly suited to cover industrial sites such as factories and plants is the fact that the material is especially treated to ensure long-lasting life and service. Built from oil-based by-products and treated with stabilising and modifying products for optimal performance, EPDM is highly resistant to some of the main hazards typically faced by industrial roofing, such as UV exposure, inclement weather, roof traffic (from birds as well as humans,) puncturing and impact. These roofs are also able to retain their pliable nature and ability to withstand structural movement even under extreme weather conditions or heavy usage, further contributing to make them highly regarded among industrial roofing specialists.

As well as being durable and resistant, typically with a lifespan of several decades, EPDM roofs also stand out for being easy to install. The process of installing an EPDM rubber roof is relatively straightforward, and requires no specialised equipment; rather, the roof is simply glued to the deck by way of an adhesive, after which the seams are sealed using special tape. This easy, quick installation process is another major selling point in favour of EPDM roofs where builders and factory managers are concerned, and when combined with the sturdy nature of the material, contributes to make this type of industrial roofing the most common and widespread in the western world nowadays.

PVC Roofing

EPDM rubber is not, however, the only material commonly used as industrial roofing; in fact, this type of covering has one major ‘competitor’, which has been around for just as long and is almost as popular.

This is, of course, PVC roofing, a type of industrial roofing developed in the 1960s, precisely as a response to the perceived shortcomings of EPDM rubber roofing. Initially developed in Europe, this type of roofing quickly caught on the world over, and has been the main alternative to EPDM roofs ever since.

A typical PVC roof is made up of a single-ply, polyester-reinforced membrane, with hot-air welded seams. This membrane is subjected to a series of treatments during the manufacturing process in order to enhance its stability, flexibility and resistance to tearing and breakages, ensuring the longevity of the material. The hot-air seams further help make the roofing membrane pliable and water-tight, even under extreme weather conditions, thereby protecting the roofing from common issues such as ponding water, dampness, fungi, bacteria and alkali. In addition, PVC roofing tends to be resistant against UV radiation, fire and chemicals, ensuring well-rounded protection for any industrial property it is applied to.

If there is one downside to PVC-based industrial roofing as opposed to its EPDM counterpart, it is that it is slightly pricier. This is offset, however, by the fact that it is also, in every regard, superior to it: sturdier, longer-lasting, more environmentally friendly and offering superior protection, an important aspect when dealing with sensitive equipment or heavy machinery, such as tends to exist in industrial premises.


Ultimately, the choice between EPDM and PVC-based roofing comes down to the personal preference of each factory owner. Both of these materials tend to be warranted for a minimum of ten years, with their lifespans often extending to a second decade, and both offer perfectly adequate protection to any industrial building they are applied to.

PVC tends to be, overall, slightly sturdier and less prone to leakages and other defects in the long run, but is also somewhat pricier, which may be a determining factor for property managers on a budget; on the other hand, EPDM rubber is an affordable and well-rounded option for its price, but also slightly more likely to damage in the short run and with a slightly shorter lifespan. As such, the decision between one or the other ultimately comes down to the factory manager’s expectations; if they do not mind springing for a replacement in the medium term, and would rather spend less in an initial stage, EPDM is an excellent choice; otherwise, PVC should be preferred to this alternative.

Regardless of which material a factory manager goes for, however, it will no doubt come as a relief to know that either of the different types of industrial roofing will offer adequate and comprehensive protection for their industrial facility!

What Are The Most Common Types Of Industrial Cladding?

Industrial cladding is one of the most important elements in ensuring the outside face of an industrial building is kept protected from the elements and any other potential sources of damage. If properly applied, industrial cladding can protect a building from the elements and other outside sources of potential damage, and therefore extend the property’s longevity and lifespan.

Industrial cladding can be carried out in a number of ways and using a number of different materials. Each of these works in a different way, but all of them serve the same basic purpose and achieve roughly the same results; the choice of which one to use therefore comes down to each individual customer’s needs or the circumstances of the job. The lines below details the most commonly used among these methods and materials.

PVC Cladding

PVC is one of the most common materials for industrial cladding jobs, on account of being both affordable and easy to maintain, especially as compared to other types of cladding. White PVC cladding is the cheapest type of industrial cladding available on the market, making it a popular choice among factory owners.

Tile Hanging

Tile hanging is the most traditional method used in industrial cladding, and also one of its most popular, alongside PVC. This is the type of material and method most often associated with cladding, and is particularly prevalent in older factory or plant buildings.

Brick Slips

Though most common in domestic buildings, brick slips are also sometimes used in industrial cladding, particularly thanks to their sturdy and resistant nature. The wide variety of styles and colours these slips tend to be available in further make them attractive to factory and plant owners looking for something different from the traditional colour schemes.

Each of these types of industrial cladding has its own strengths from an aesthetic and functional standpoint. Here at Valent Roofing we assess each individual project and look at the best methods to use in terms of safety and security above all things.

Three Water-Related Causes for Roof Repair

A previous post on this feed presented three common reasons why industrial properties might require roof repair, namely inclement weather, bird-related damage, and sub-par installation and maintenance.

However, these are far from the only factors causing an industrial building to need roof repair. There are plenty of less significant ways for an industrial roof to become damaged, many of which related to drainage or water flow. Three of these are detailed in the lines below.

Overfilled Gutters

Gutters are an essential part of any roof, as they are the main element facilitating the drainage process. However, they do also tend to become filled or blocked rather easily, whether by birds nesting in them or by debris such as leaves or branches floating in with the wind. As such, they require frequent, thorough cleaning, to ensure the flow of water is unimpeded. However, many owners of industrial buildings neglect this process, usually resulting in roof repair professionals having to intervene and correct the issue.

Water Leakage

Water leakage is a frequent problem in industrial roofing, and can have a number of causes, from the age of the roof itself to potentially faulty installation or missing sections of roof. Whatever the cause, however, this issue inevitably brings about the need for roof repair, lest the materials or furniture inside the property be damaged.

Water Ponding

In addition to water leaking through into the inside of the building, there is also the danger of pools forming on the roof, usually as a result of roof debris or blocked drainage, as described above. Industrial properties where this problem is spotted usually need debris cleaned from their roof or their gutters cleaned.

These are only three of the many ways in which water-related damage can bring about the need for roof repair. To avoid unnecessary expenses, the best thing for property owners to do is ensure the roof of their industrial building is regularly maintained and kept in good shape.
