Why it's vital to prevent leaks on your Westminster property
The roof on your home is a major investment. It certainly isn’t cheap to put a new roof on a home, so you want to make sure that you get the most out of your roof’s lifespan. The weather in Pimlico can certainly be harsh at times; it may rain for days, or your roof may have to bear the weight of snow for several days at a time. Westminster roof sealing companies can help you extend the life of your roof, keep your home dry, and even prevent expensive repairs due to leaks.
The process of waterproofing a roof essentially restores the surface by filling cracks, stopping leaks, and protecting smooth surfaces. Instead of rainwater and melting precipitation seeping into cracks, it can simply roll off your flat roof into gutters or onto the ground as it should. Waterproof roof coatings can last for up to a decade or more, which provides homeowners with peace of mind that their homes will remain structurally sound, even despite harsh weather conditions.
Discover the tell-tale signs that your Pimlico roof needs to be waterproofed
If you’re building a home with a flat roof, you should have it waterproofed before you move in. This way, you can protect your investment from the start and provide yourself with some extra peace of mind. If you’ve just purchased a home with a flat roof, it’s important to call a contractor to inspect the roof for things like damage and leaks. Your contractor can likely tell you about the condition of your Pimlico roof and whether a coating should be applied (or reapplied.) Some coatings are good for five years, and others are good for a decade or more. You should waterproof your roof per the coating manufacturer’s recommendations or more frequently in particularly harsh weather conditions.
There are several different types of waterproof coatings that you can use to protect your roof for many years to come, but they all go on wet or tacky and take time to dry. Most these coatings will require anywhere from eight to 24 hours to set, but these timeframes can go even higher if the coatings are applied during especially humid conditions. As such, your contractor should only attempt roof waterproofing jobs during times that will be free of rain and relatively dry. The summer months are often the best in Pimlico and the Westminster area as they offer up warmer temperatures, lower humidity, and less frequent precipitation.
Deciding on how much of your roof needs to be sealed
Many home and business owners ask about the differences between partial and total waterproofing, especially if they seem to have a problem with leaks in just one area of their roofs. There are a couple of instances in which partial waterproofing may be acceptable, but for the most part, total waterproofing is always the best option.
Total waterproofing occurs when a material or coating is added to the entirety of your roof to protect against damage from the sun or weather and prevent leaks in the future. Total flat roof waterproofing provides extra peace of mind, and in many cases, it is guaranteed by the contractor or the sealant manufacturer.
Partial waterproofing occurs when only one area of the roof is coated in a sealant or other protective material. This is most common when an area of the roof has been damaged by a falling limb or other debris, but the rest of the roof is still intact and covered by a waterproofing material. In these cases, there are companies that can waterproof the new (or repaired) section of the roof and blend it in with the existing coating.
With this information in mind, Pimlico flat roof sealing work should only be partial following damage to a specific part of the roof. Otherwise, total waterproofing is recommended as it will protect your roof – as well as your home or business) – in its entirety.
Depending on the material there are various methods of sealing a roof
There are many different methods a contractor may use to waterproof your roof, and each one has its own unique set of pros and cons.
This is the simplest flat roof sealing method out there, but it is typically reserved for wet areas inside of a home or building. It is rarely used in roofing because the cement-like product is especially heavy and can cause undue strain on your home’s structure.
A liquid waterproofing membrane usually goes on in coats. This consists of a primer coat that is allowed to dry before two top coats are applied by trowels, rollers, or sprayers. These membranes are far more flexible than cementitious waterproofing materials, too. After it dries, it creates a rubbery coating that can resist water and the elements. What’s more, the durability of this coating varies depending on the type of polymer the manufacturer uses when it makes the product.
Bituminous membrane waterproofing is very popular in Pimlico, and it’s also common on homes or businesses with roofs that have a very limited slope. These are applied in two different ways – by a torch-on process or through self-adhesion. The torch-on product requires heat to adhere to the surface of the roof, but the self-adhesive product sticks without heat. However, because the bonding properties diminish over time, most contractors prefer the torch-on bituminous membranes.
Bituminous coatings are typically comprised of asphalt, which means they can break down when exposed to sunlight. As such, many manufacturers of bituminous coatings intended for roofing projects will modify them with flexible polyurethane or even acrylic polymers. These coatings are more popular than membranes because they tend to last longer after they are applied.
Finally, a polyurethane liquid membrane is also quite popular in Westminster flat roof waterproofing projects. In fact, it’s recommended for areas that are exposed to not only the sun, but also to wind and other elements that may cause weathering. Polyurethane, by its very nature, stands up to harsh temperatures and extreme precipitation. It lasts longer than any other type of waterproofing membrane, but it’s also the most expensive of all the roof waterproofing methods.
Get an idea of the costs involved in sealing your roof
There are many things that may affect the price associated with waterproofing Pimlico flat roofing, too.
On average, aside from the cost of materials, which you can calculate based upon the size of your roof and the recommended thickness of the material, bear in mind that most contractors charge roughly £2 to £3 per square meter to apply the material or sealant. For example, the labour alone for a 800 square meter roof may come to £1600 to £2400, depending on the contractor. Therefore, it is always a great idea to obtain quotes from multiple contractors. It will help you get the best possible price for your project.
A compilation of FAQs for your convenience
We thought it might be useful to provide answers to some of the frequently asked questions we receive regarding sealing a flat roof. If you'd like to know more, why not apply online and speak to a professional about your roofing needs?
The best way to determine which Westminster roof waterproofing method is right for you is to get in touch with local contractors who have the knowledge and expertise to make recommendations based on your unique situation.
If you’ve had your roof waterproofed in the last few years and only a small section is leaking, it may be possible to only waterproof that area. However, if it has been several years since your roof was last sealed, it’s almost always advisable to seal your roof in its entirety. This will protect against future leaks and provide you with unsurpassed peace of mind.
Absolutely. In fact, if you’ve recently purchased any property with a flat roof, it’s always a good idea to have the roof inspected before you make any decisions. A roofing contractor should be able to tell you what sort of waterproofing was applied in the past – if any at all – and whether it is time to waterproof again.
The aesthetic appearance of your finished project will vary based upon the product used to seal your roof. Some coatings and membranes are clear, which will hardly affect the appearance of your roof at all. Bituminous membranes and coatings will provide an asphalt-like look, and polyurethane sealants come in a variety of colours based upon the polymers used in them. In some cases, you can choose to have your coating coloured to your preferences, but not all contractors do this.
The materials used in flat roof waterproofing are designed not to fade. In fact, if you have a metal flat roof, these coatings may actually protect your roof from rust and improve its longevity.
If your flat roof is in poor condition and needs to be replaced, waterproofing is not advisable. Waterproofing only works well on roofs that are in good condition. You should have your roof replaced or repaired as required, then consider waterproofing to protect your investment for the future.
What types of Pimlico roofing will benefit from being sealed?
When it comes to flat roofs themselves, there are several different types of materials and systems in use throughout Westminster and the Pimlico area.
This stands for Built Up Roofing, and are sometimes called “tar and gravel” roofs. Asphalt BUR is the most commonly-found flat roofing material in the area. It’s durable, affordable, and lasts a long time when compared to some of other types of roofing systems. It is typically comprised of four layers of materials, which are bitumen and fabric, that create a finished membrane.
Ethylene Propylene Diene Monomer, or EPDM, is a type of single-ply membrane that is rubber-like in texture. It is used on flat and low-slope roofing surfaces that is incredibly inexpensive due to the nature of the material and the minimal labour required in its application. When applied properly by a professional, it can last as long as 25 years.
TPO stands for Thermoplastic Olefin, and it is essentially sheeted material made with polypropylene and ethylene polymers that have been reinforced with polyester. They contain other materials, too, including flame retardants, colourants, UV absorbers, and more. PVC sheets offer more flexibility than TPO, and these contain stabilizers, plasticizers, and colourants designed to offer aesthetic appeal.
This is another single-ply roofing material designed to provide a shield against ice and water, but the surface is impregnated with a variety of materials designed to help protect against weathering. It can reflect light in the summer and lower cooling costs, but it does little to help with heating costs during the cooler months.

Need urgent help with your roofing? Read below
Many of the flat roof sealing products that Westminster contractors use require dry conditions to apply and cure. However, there are some products out there that are made to be used in emergencies when there are small to moderate leaks and no breaks in the wet weather. Some of these are DIY-friendly, meaning home and business owners may be able to apply them on their own to prevent damage. However, it is important to remember that emergency waterproofing products are all temporary fixes and will not take the place of professional waterproofing done by a qualified contractor.
Many of these compounds are fibred, which means they stay somewhat liquefied and loose throughout their lifespans. They are made to be applied in wet conditions when the source of the leak isn’t readily known. The home or business owner can simply spread the material over the portion of the roof that is causing the leak, and the fibrous material will reroute water away from the area, thus temporarily stopping the leak.
