4 Types of Roof Coatings

A rubber roof coating is essentially a composite made up of numerous materials. It is a protective layer applied to the roof's exterior to provide shelter to the interior of a building or dwelling.

Acting as the “cherry on top,” a roof coating often extends the life of a roof, seals the roof to prevent leaks, and keeps heat out (acting as a reflective layer). Some roof coatings are better than others, as we’ll explore below with the types of roof coatings in the UK.

“You don’t need to coat a rubber roof. The EPDM membrane is the final and top layer of waterproofing sheet.”

Some other roofing membranes, like EPDM, can also eliminate the need for a roof coating, thanks to their durable properties. Rubber sheets or liquid rubber forms offer solutions for just about every need and are specifically designed to protect your roof and withstand various weather conditions and temperatures.

Factors to Consider When Choosing Roofing Material

If you’ve landed here, chances are you need to replace or construct a roof, which is one of the most crucial decisions any homeowner can make. The type of roof you choose affects the property's aesthetics, durability, energy efficiency, and long-term maintenance needs, not to mention the property’s resale value.

So, when selecting a roofing material that will stand the test of time, you’ll need to consider factors like cost, lifespan, climate suitability, complexity of installation, and environmental impact. Below, we’ll explore all these factors and the advantages and disadvantages of some popular UK roofing materials.

Don't Forget to Consider These Factors Before Purchasing a New Roof

Tips from roofing experts

EPDM RUBBER ROOFING IS THE PERFECT SOLUTION FOR REPLACING OLD FLAT ROOFS

The cost of a new or replacement roof

One primary factor influencing the choice of roofing material is cost—unless you have a big budget, the overall cost of your roof is not a problem.

If you’re trying to stay within your budget, you might find that materials like asphalt shingles and felt are relatively affordable upfront compared to other materials like slate, clay, and metal, which require a higher initial investment.

However, as you’ll likely already know, cheaper doesn’t mean better, so you’ll likely pay for cheap roofing materials like asphalt in the long run.

You might not have considered rubber roofing, which falls into its own category.

The EPDM material offers a cost-effective alternative to traditional materials, making it an affordable yet attractive option for budget-conscious households searching for quality roofing without breaking the bank.

Read more.

The lifespan of your roof

Another critical consideration is the longevity of the roofing material of choice, as it will directly impact the need for future repairs or replacements.

Materials like slate, metal, and rubber are known for their exceptional durability. With the right care and maintenance, they can last over 40 years or more.

Cheaper roof materials, on the other hand, like asphalt shingles, typically have a lifespan of around 20 years.

Still, you’ll also have to consider how they withstand particular weather conditions, which might make them more susceptible to repairs during this time.

Your environmental footprint

With sustainability becoming increasingly important to homeowners, considering the environmental impact of your roofing material is a must.

Materials like metal and rubber are typically made from recycled materials, which are again recycled at the end of their lifespan, helping to reduce their carbon footprint.

In contrast, materials like asphalt contribute to landfill waste and contain harmful chemicals, making it a non-sustainable choice for environmentally conscious homeowners.

In addition, rubber roofs' energy-efficient properties can help homeowners reduce heating and cooling costs, another critical factor in today’s energy market.

New Roof Costs

First, when it comes to pricing up a new roof, one of the main factors influencing the final cost is the material you choose. With most owners aiming for durability, affordability, and aesthetics, it’s important to weigh up the pros and cons of each material, exploring the benefits and understanding not just the initial costs but also the lifetime costs. Then, can you only decide what is best for your budget and long-term maintenance needs.

Roofing Material Costs, Considerations & Financial Choices

Tips from roofing experts

new roof cost

New roof costs vary on the size, complexity and type of material used

As roofing experts, we know that the cost of your project can vary depending on factors such as the roof's size, the installation's complexity, and, more importantly, the type of material you choose.

For example, asphalt or felt are often the cheapest roofing materials. While their price makes them attractive, the initial low cost comes with a trade-off in terms of longevity.

For example, the cost of asphalt roofs is mostly their only benefit. Disadvantages include a lack of energy efficiency and durability, with mildew as a common problem. As asphalt shingles are susceptible to weather damage, they require frequent repairs and replacements.

So, while some roofing materials products might seem the best economic decision upfront, the cumulative costs of replacements and maintenance certainly outweigh the initial affordability in the long run, proving that not all cheap roofing materials are suitable long-term investments.

There is one affordable and durable option…

On the other end of the spectrum is rubber roofing, which emerges as a cost-effective alternative that creates a great balance between affordability and durability.

EPDM roofing (ethylene propylene diene monomer) is a synthetic option that offers several advantages over traditional, pricier options, keeping new roof costs low.

Rubber roofs are inexpensive to install compared to other materials like metal or slate, often making them the number one option for budget-conscious homeowners. Plus, their low maintenance requirements contribute to further cost savings over time.

Rubber’s resilience means fewer repairs and replacements, significantly reducing long-term maintenance costs.

When you consider rubber’s durability, it’s a wiser investment for homeowners who want a roof to stand the test of time.

With a lifespan of 40 years or more, rubber roofs offer the best value for money for its upfront cost.

13 Of The Most Popular Different Roof Types In The UK

All of the different types of roofs uk

Different Types of Roofs

Understandably, homeowners will first consider aesthetics when choosing the style of their new roof. While this is important, architects, for example, would consider efficiency, lifespan, durability, and the best protective barrier against weather. There are numerous types of roof to choose from.

So, when it comes to new build projects, choosing a roof shape can be challenging, especially with so many different roof types featuring their own unique properties.

Below, we break down the most used roof designs, their benefits, durability, and cost per yard. Please note, rubber roofing and EPDM roofing materials are only suitable for roofs that are flat or have a very low pitch. FAQs.

Ranked – Types of Roofs

Tips from roofing experts

FLAT ROOF TYPE1

ROOM TYPE 1: Flat Roof

  • Durability: 40-50 years
  • Benefits: Easier to repair. Highly durable. Almost completely weatherproof.

Flat roofs are low-sloped roofs types that appear flat and allow water to run off by channelling it to a drain. With flat roofs, waterproofing materials are essential to guarantee optimal watertightness and prevent leaking.  More on flat roofs.

Flat roofs are widely regarded as an efficient way to maximise space in a building. Plus, as the surface area is the same as the house, they are cheaper to install than sloping roofs. They are often used in commercial and institutional facilities and residential extensions.

As they do not drain the same way as pitched roofs, they can be prone to leaking without professional sealing, which might require more regular maintenance. However, they are easier to repair and maintain than other types of roofs. See parapet flat roofs or Commercial flat roofs.

Roof Type 2: Garage and shed roofs

When choosing a roof design and material, you don’t need to consider this only for your main property but also for outhouses, sheds, and garages.

Garage roofs in the UK need to withstand low temperatures, prevent water ingress, and encourage good ventilation to protect your items stored from harsh British weather.

As most garage roofs are flat, sheets or tiles are not always suitable to protect from leaks or condensation. Rather, garage EPDM roof membranes are specially designed to withstand the challenges of flat roofs, making it a great material choice. See products.

Non-flat garage roofs tend to use a mono-pitch roof type.

Roof Type 3: Garden rooms

Residential-grade Garden rooms are extremely popular and boost your property’s value. Seeing as their construction is highly modern and sleek, they tend to always feature flat roofs, with the go-to material of choice being EPDM rubber for it’s numerous benefits. Check out rooflights to make the space even more modern-looking.

Roof Type 4: Extension roofs

For any homeowner building a single-story extension to their property looking to keep costs low, and opting for a modern solution should consider the flexible, simple and affordable flat roof solution. Great for extensions of any shape or size, flat roofs featuring rubber materials are cheaper and faster to create. Plus, they’re easy to maintain and repair.

Roof Type 5: Gable Roof

  • Durability: 40 years
  • Benefits: Excellent drainage for rain and snow and more weather resistant. Better ventilation within the home.

Gable roofs types are popular and common as they are easy to build and shed water well. It’s the most basic type of sloping roof, consisting of two equally sized sloping roof surfaces which meet at the top ridge of a rectangular house. As the triangle shape is the most stable form in engineering, the gable roof is strong, making it a popular choice for British homes. Plus, they allow for larger loft spaces.

A drawback to be aware of with Gable Roof types is that they are more prone to wind damage as the gable roof structure can attract wind, which can damage the shingles. So, if you live in an area prone to high winds or extreme weather, gable roofs are not the best choice.

Similar roofs are T-shaped and L-shaped.

More on repairing a gable roof.

hip roof image

Roof Type 6: Hip Roof

  • Durability: 40-50 years
  • Benefits: Great for high wind and snowy areas, leaving no standing water.

Another popular roof, the hip roof, which is pyramid-shaped, allows for better performance in areas with strong winds due to extreme vertical elements. However, gable roofs do not allow optimal ventilation or provide as much roof space for loft spaces. Hipped roofs with a high pitch are more popular on properties or institutions as they are simple to build.

The inward slope of all four sides makes this roof type sturdier and more durable, which is a definite advantage in extreme climates. More.

Roof Type 7: Dutch Roof

  • Durability: 60 years
  • Benefits: Great for high wind and snowy areas, leaving no standing water.

The Dutch roof is unique because it combines the benefits of the gable and hipped roof. The main benefits are that the design facilities access to the underside of the roof and adds extra space and natural light within the property. Best used in residential projects to add a higher flare of design whilst maximising space, Dutch roofs feature high strength and optimal water drainage.

Not as common as alternatives in the UK, the Dutch roof is often referred to as a Gablet roof, which allows for more standing room in a loft space but is more complex and costly to create.

dutch roof image
barrel roof image

Roof Type 8: Barrel vault roofs

  • Durability: 50-100 years
  • Benefits: Complete resistance to wind, hail, and fire damage.

The Barrel roof type uses a continuous arch shape, like a semi-circle, to create a curved style of room and is often paired with a metal roof tile solution. In the UK, it's often seen in the architecture of churches or museums, or in the form of shelters, taking inspiration from Spanish and Mediterranean styles.

However, a high barrel tile roofing system can generally cost two to three times as much as an asphalt roof.

Roof Type 9: Shed Roof

  • Durability: 10-50 years, depending on the material.
  • Benefits: Good for extensions and attached buildings.

Shed roofs are very similar to flat roofs, but they have more pitch and tend to be used more as additions to properties with other roof styles. The single-pitched roof is a single gable that slopes to one side and is not connected to other parts of the property.

Drainage is effective and simple, with no connection points to other slopes, making it easier to maintain. It’s a low-cost, long-lasting material, making it a popular choice. More.

Essesstionaly, the EPDM rubber membrane mirrors a number of benefits found in natural rubber whilst making the material UV resistant.
butterfly roof image

Roof Type 10: Butterfly Roof

  • Durability: Up to 50 years.
  • Benefits: Good aerodynamic properties. Resistant to weather damage from high winds.

Also referred to as the V-roof, the Butterfly roof is modern and aesthetically pleasing, where the roof slopes inwards, making it an inverted gable roof. However, it’s typically associated with the mid-20th century and modern US architecture. The Butterfly roof type provides adequate ventilation but prevents challenges for draining water as the rain is collected and then channelled to a drain.

Roof Type 11: Gambrel Roof

  • Durability: With the right maintenance, it can last over a century. Depending also on material.
  • Benefits: Suitable for most climates. Increased interior space.

Typically used in contemporary barns, a gambrel roof is like a gavel roof, but instead of being triangular, it pitches at two different angles that are steeper at the bottom. It provides more space in the loft and is better suited for living space; however, the weight can sometimes push the steep outwards. The design is most commonly seen in traditional American aesthetics.

gambrel roof image
dormer roof image

Roof Type 12: Dormer Roof

  • Durability: Up to 50 years.
  • Benefits: Good aerodynamic properties. Resistant to weather damage from high winds.

Typically, a dormer roof, is an addition to an existing roof, where a window and a roof, whether gable, hipped or flat protrudes 90 degrees from the existing slope. The addition of a dormer roof creates usable space extending from the roof to provide more natural light and headroom.

Roof Type 13: M Shaped Roof

  • Durability: Up to 50 years.
  • Benefits: Good for natural light when windows are installed. Extra storage space.

Typically seen with semi-detached houses or extensions, m-shaped roofs are double gables roofs with two sloped sides that meet in the middle, creating an M shape. They allow for better natural light to enter and have a central gutter to prevent snow and rain from building up. It’s not a common roof type for single homes, but the shape can be incorporated into modern designs.

m-shaped roof
flat roof porch

 Porch Roofs

  • Durability: 40-50 years.
  • Benefits: Increased home value, additional space and improved aesthetics.

Porch roofs can feature several shapes, from flat to pitch, with the type you choose is based on the fitting of the house's overall design or made on a price decision. The most common porch roof tends to be a gable roof. However, more homes nationwide are opting for flat roofs as an alternative.

How to Fix a Leaking Roof

Not only do leaking roofs cause damage to the interior of your home, but they could potentially lead to costly repairs in the thousands.

But as roofing experts, we know that first, it’s important to understand the cause of the leak and to take into consideration your current roofing material as a factor in not helping you in your fight to

As homeowners ourselves, we know how a leaking roof is a homeowner’s nightmare.

The Fastest Way to Stop a Leaking Roof

Tips from roofing experts

Roofing materials that are the best for preventing leaks

  • EPDM has emerged as the perfect solution for roof repairs, particularly flat roofs.
  • Its flexible and elastic nature allows it to expand and contract with changing weather conditions.
  • Rubber roofing is also lightweight, making it applicable to most roof structures.

Rubber roofing materials like EPDM help homeowners address the issue of roof leaks and should be considered a leading option to prevent further leaks.

Rubber roofs are incredibly great at weatherproofing your roof and protecting your home against severe weather, which we see a lot here in the UK.

Not to mention that it’s one of the most cost-effective roofing materials. However, rubber roofing can only be applied to flat and low-sloped roofs, where shingled roofing is no longer the best option.

Best materials to prevent leaking on pitched roofs:

  • Synthetic rubber materials
  • Concrete or clay tiles
  • Slate roofing
  • Proper roof deck preparation and underlayment, and insulation

*Pro tip: be careful with materials like concrete or slate, which are heavier, meaning the root structure needs to be designed to support the weight of these heavier materials.

What professionals recommend:

Professionals tend to recommend materials that feature waterproof membranes, flashing systems and sealants to prevent leaks, providing an effective barrier from moisture intrusion and improving durability and resistance to bad weather conditions.

Roof repair costs

The cost to repair your roof can vary, depending on the cause of the leak, the severity and the action required to fix it. However, if you’re using a material that is not the best equipped to withstand the elements, it might be better to consider a replacement rather than a repair.

For example, rubber roofing membranes are particularly popular for preventing leaks and waterproofing your roof. Plus, if your roof ever needs a repair in the future, it’s cheaper and easier to repair with rubber. For example, minor damages, such as punctures or tears, can be easily patched with uncured flashing tape or a specially designed patch kit.

In particular wet areas, polyurethane, silicone or rubber sealants are even better to prevent water from penetrating the roof and causing internal damage. See Poylmer Sealant from £10.50 or Water-Based Deck Adhesive from £24.00.

Using rubber membranes for your repairs will save you time and reduce the overall maintenance costs associated with roof repairs, ensuring a secure and leak-free home for years to come.

Causes of leaks

  • Damaged or missing shingles (shingles that have cracked, curled or broke)
  • Exposure to harsh weather conditions (rain, snow, UV rays)
  • Strong winds can lift or remove shingles leaving the underlying roof vulnerable to water infiltration.
  • Inadequate flashing installed or damaged flashing around roof openings like chimneys, vents, and skylights.
  • Improper sealing.

Roofing materials that are more prone to leaks

  • Traditional asphalt shingles deteriorate over time, especially in regions with extreme weather conditions.
  • Felt roofs are highly susceptible to damage and leaks, this is because felt is known to weaken in wet and windy weather.
  • GRP or fibreglass roofs often leak due to poor installation, causing the roof to crack and allowing water to enter.
  • Metal roofs, whilst durable, develop rust and corrosion more easily.

4 Essential Steps For Fixing A Flat Roof

Fixing a flat roof leak

In 2024, flat roofs are mostly water-resistant, with homeowners usually not having to worry about water damage. But flat roofs have not always had the best reputation, as in the past, they’ve been known to be more challenging to get rainwater to run off them.

However, with the involvement of professionals and innovative rubber materials, it’s possible to extend the life of flat roofs and preventing leaks altogether.

But if your current flat roof has not been installed to be watertight, or you’re noticing water pooling, then it’s likely that the water will work its way through the materials – which is why it’s especially vital to waterproof your roof and maintain them. But first, let’s walk you through the steps to repair your leaking flat roof, and then advise you on the best next steps to keep it dry!

Follow These Steps to Fix Leaks & Keep Your Roof Dry

Tips from roofing experts

Fixing A Flat Roof

Step 1:

Identifying the Source of the Flat Roof Leak

  • Carefully inspect the flat roof, paying close attention to signs of damage like cracks, tears, or gaps in your roofing material. Pay special attention to areas where water might accumulate or build up, like around drains, vents or flashing. This will prevent future leaking.
  • A hose can simulate rainfall so you can observe where water runs off and where water enters the roof.
  • Determine the extent of the damage. Involve a professional if you have to.

Step 2:

Clean and Prepare the Flat Roof Surface

  • Clean and prepare the roof surface for repair materials. If your roof material is EPDM, you can use our EPDM Membrane Cleaner (£11.99) to remove contaminants from the surface.
  • Remove debris, dirt and loose roof material using a brush or pressure washer.
  • Before repairing, ensure the surface is dry and free of moisture. This will allow the sealants and new materials to adhere properly.

Recommended products to repair a leaking flat roof:

  • Primers can be ensured to improve adhesion and ensure a long-lasting repair. Explore our EPDM Primer (£7.50).
  • 5″ Circular Patch (£7.50) designed to flash outside corners or to be used as a cover patch for small repairs.
  • 12″ Uncured Flashing Tape (£24.00) - ideal for flashing and waterproofing.
  • Flashing can prevent leaks on a flat roof and is typically installed around roof penetrations like vents and chimneys. See flashing products.

Apply Rubber Roofing Sealant

Using a rubber roofing sealant is a versatile and durable solution for repairing leaks in flat roofs, as it forms a flexible, waterproof barrier that withstands harsh weather conditions and temperatures.

  • Using a brush, generously apply the rubber roofing sealant to areas where the leak occurs. See professional kits.
  • Overlap the damaged area of the roof by several inches to create a watertight seal.
  • Allow the sealant to dry completely according to instructions, and proceed to the next step.

Step 4

Perform Regular Maintenance

The trick to avoiding a leaking flat roof is prevention and maintenance. You can prolong the life of your flat roof by performing regular maintenance checks to inspect for any signs of wear or damage.

Ensure the roof is clear and clean of debris to prevent water from pooling. Also trim any overhanging branches or any vegetation that could cause damage to the roof’s surface. Protective coating or sealants can also further enhance the waterproofing quality of your rubber roof.

How Long Does a Flat Roof Last? | Rubber Roofing Direct

How Long Does a Flat Roof Last?

A rubber roof is incredibly long-lasting and durable. The rubber used for making the synthetic rubber membrane isn't damaged by the sun's UV rays.

If installed correctly, you can expect a rubber flat roof to last up to 50 years.

Because an EPDM flat roof comprises durable rubber, it can withstand extreme weather conditions such as hail or snow and typical weather such as rain and strong winds.

Furthermore, if the rubber membrane is ever damaged, torn, or split, it's straightforward to repair quickly. A flat rubber roof has been installed commonly since the 1970s, which is why it's popular with homeowners.

It requires minimal maintenance throughout its lifetime

This makes rubber roof membranes attractive for commercial and privately owned properties. They're incredibly cost-effective and generally have a longer lifespan than traditional materials such as asphalt or felt.

How Can I Improve My Flat Roofing Installation?

By simply installing a rubber roof membrane and always using flashing tape, even the most challenging flat roofs can be made watertight!

We also offer a range of products designed to divert rainwater from your flat roof to your drains properly.

Rainwater doesn't affect the properties of the rubber membrane, but we offer a range of accessories designed to manage roof water runoff correctly. All our rubber flat roofs come with a 20- or 25-year warranty to certified installers.

  • Unlike traditional materials such as tiles, slates, steel or felt, the roof membrane isn't vulnerable to rust or moss growing on it, nor will it tear, split or crack.

WHY DO EPDM ROOFS LAST LONGER THAN OTHER MATERIALS?

Part of the EPDM chemical structure is made up of carbon black, which is resistant to material decomposition and degradation from UV exposure. It is also highly flexible, expanding and contracting when temperatures become cold or hot. It can withstand high winds, and its synthetic rubber composition is totally waterproof.

Its longevity was also proven when 2010, the EPDM Roofing Association (ERA) based i,n Washington DC test,ed ,roof membrane samples of at lethat weret 30 years old. ERA evaluated its mechanical and physical properties using standards set by ASTM (American Society for Testing and Materials standards). Properties evaluated included its tearistance, tensile strength and wat,er absorption amongst, others. The results proved positive, proving that even after thirty years of exposure, all ASTM minimums were exceeded or met.

Other Benefits of EPDM Rubber Roofing

The advantage of a longer lifespan is only one of the many benefits of this type of roofing material. You can find some of the other ones below.

GO GREEN

Endorsed by Greenpeace as a low impact membrane and 100% recyclable you can do your bit for the environment if you choose EPDM as your roof replacement material. The extended lifespan and reusability of EPDM mean that it has a limited impact on the environment.

COST-EFFECTIVE

Over its lifetime, EPDM is the most cost-efficient material for a flat roof. You'll find cheaper materials, but they sacrifice longevity. Some materials, such as fibreglass, are comparable, but you can expect to pay a much higher price.

LOW MAINTENANCE

If the rubber roofing has been installed correctly, there is little post-installation maintenance to carry out.

How EPDM Has Evolved Over The Years

EPDM roofing was first introduced to the market in 1962 and became a popular alternative to asphalt during the seventies and eighties. When the Middle East oil embargo resulted in increased prices and lower-quality asphalt, EPDM positioned itself as a contender in the flat roofing market and hasn't looked back since.

Over the decades, advancements have been made to the product making it more durable and longer-lasting than ever. Still, even the less developed EPDM roofing systems of the sixties are protecting flat roof buildings to this day, which stands as a testament to its robustness. Advancements over the years include improvements to the seams, making EPDM more puncture resistant and stronger flashing details.

How Does Rubber Compare with Other Roofing Materials?

Of course, rubber roofing isn't the only material used for flat roofs. Let's examine some other flat roofing materials and find out how long they last.

FIBREGLASS FLAT ROOFS, HOW LONG DO THEY LAST?

Fibreglass roofing, also known as GRP (Glass Reinforced Polyester) Roofing, can last for 30 years or more, so in longevity, it is close to EPDM. However, you also have to consider the price, which is much higher, and installation fees. Many homeowners like to install rubber roofing themselves as it is a relatively simple process and reduces overall costs. GRP involves a much more complicated installation method and needs to be carried out by a professional.

WHAT IS THE LIFESPAN OF A FELT ROOF?

A felt roof will last somewhere between 10 and 20 years. The older pour and roll method of installation has now been superseded by torch-on felt which is melt welded on to a flat roof. Felt is generally the least expensive option and was a common choice for many flat roofs before materials such as rubber became more popular. Still, even though it is cheap, it does degrade faster, can't be DIY installed and, as pointed out, may need replacing in as little as ten years. Felt roofs.

WHAT'S THE LIFE EXPECTANCY OF TPO FLAT ROOFING?

TPO (Thermoplastic polyolefin elastomers) is the new kid on the block so it is a bit of an unknown, estimates are that it could last around 20 years. The price of a TPO flat roof is similar to that of EPDM  as is its durability, but the latter is still the winner when it comes to life expectancy by a few decades.

How to Maintain a Flat Rubber Roof

Maintenance doesn't have to be a chore, but it's best to carry it out a couple of times a year, we'd suggest once in spring after the cold, damp winter months and once in autumn after the hot summer months. You should also check the roof after heavy rain to make sure that water isn't pooling on it.

When you carry out your bi-annual maintenance, remove any debris, such as leaves from the roof, that could block the water from draining and cause it to pool.

If there are overhanging tree branches above your roof then cut them back, heavy branches falling on the rubber membrane could damage it.

Just as with any other roof, you will need to undertake repairs occasionally. Fortunately, there are inexpensive repair kits and patches designed for easy maintenance of an EPDM roof.

Common Issues That Can Affect the Longevity of a Flat Roof

Problems that will affect the life expectancy of your flat roof can vary depending on the material used, and as we discussed above, ensure that you do a little maintenance from time to time.

A poorly installed flat roof can also affect its performance. Either use a professional to do the work, or if you do it yourself, take your time and follow the instructions closely. Also, aim to choose the highest-quality material you can afford from a reputable dealer. Using High-quality rubber-like Flexiproof and correct installation will ensure that your investment is long-lasting.

When Does a Flat Roof Need Replacing?

If your roof is leaking, the most obvious place to start is trying to repair it, but in most cases, it will need replacing. If the leaking is extensive, you might want to use the services of a roofing professional to check that it is structurally sound enough to install new roofing.

If water is continually pooling on your roof, this could also be a sign that it needs replacing. If this frequently occurs and the water has been left over an extended time, it could cause leaking or rotting.

It might just be time to update your roofing system because it has become outdated. If you have a felt roof, for instance, and it is ten years or older, it might be best to pre-empt any roofing issues before they occur. If you invest in a new rubber roof, it is likely to be a one-off cost and could last 50 years or more giving you peace of mind that your home is protected from the elements for decades to come.
