Why Choose Vanguard CladGuard™ Coating for Commercial & Industrial Roofs?

Images from Sharmans

Not every roof needs removing. In fact, many still have a sound structure beneath the surface wear. Coating allows us to refurbish these roofs quickly and effectively, sealing over cracks, corrosion and damage with a seamless waterproof layer that’s built to last. 

If you’re looking for something that will last and protect, a high-quality spray or roller applied coating provides exceptional durability, resistant to UV exposure, chemicals and extreme temperature fluctuations (all big causes of roof deterioration and damage). 

When roof sheets are cut, the protective coating and galvanised layer are breached, exposing bare steel to moisture, chemicals, and airborne contaminants. Left untreated, this corrosion spreads leading to leaks, structural damage, and costly downtime. This problem is especially challenging in coastal areas where the weather conditions accelerate it. 

One of the key advantages of coating is its ability to create a seamless, uniform membrane over complex roof shapes and profiles. Traditional application methods can struggle with hard-to-reach areas, but spray application ensures complete, consistent coverage with excellent adhesion. This not only enhances the lifespan but also improves the roof’s aesthetic appearance.

From commercial buildings, hospitals, hotels, busy care homes, apartment blocks and warehouses, our coating service offers a reliable, tidy and budget-friendly option that doesn’t compromise on performance.

The Benefits of Coating Roofs

Cost-Effective vs. Full Replacement

If the structure is sound, there’s no need to start from scratch. Coating saves time, money and materials - making it ideal for property managers, landlords and business owners alike.

Seamless & Watertight

The liquid-applied coating forms a continuous membrane with no seams, joints or overlaps that could fail. It creates a protective barrier that keeps rain, frost and UV out.

Treats Common Problem Areas

We target issues such as cut-end corrosion, lifting metal laps and worn surfaces, especially useful for older metal roofs and profiled sheet systems.

Fast and Disruption-Free

The coating is clean, quiet and quick. We’ll be professional, efficient and will keep disruption to a minimum.

Long-Term Protection

Our coatings are UV-resistant, flexible and able to handle rain, heat and cold. Two types of systems are available and depending on which system that is chosen it will give a 10 year or 25 years guarantee to your roofs .

Backed by Warranty

All coating systems are backed by long-term manufacturer guarantees and our workmanship warranty, giving you total confidence.

How It Works: Our Coating Process

Step 1: Free Survey & Assessment

We’ll carry out a full roof inspection to assess the condition, identify any damage or corrosion and confirm suitability for coating. We then create a tailored made specification for the work needed.

Step 2: Cleaning & Preparation

We’ll clean the surface thoroughly, remove any rust or debris and carry out any necessary pre-coating fixes, including replacing fasteners or sealing joints.

Step 3: Cut-End & Lap Treatment (if needed)

For metal roofs, we’ll treat cut-end corrosion and seal laps using flexible, weather-resistant sealants to prevent future failures.

Step 4: Coating Application

We apply the high-performance coating in layers, forming a seamless, waterproof membrane that cures into a strong, flexible barrier.

Step 5: Final Quality Check

Once the coating has cured, both the Vanguard team and manufacturer will inspect everything carefully to ensure it’s bonded, watertight and finished to a high standard.

Step 6: Warranty & Maintenance Advice

We’ll issue your Vanguard warranty alongside the manufacturer’s warranty. We’ll also provide guidance on future maintenance and checks to help you get the most from your new coating.

Excellent from start to finish – highly recommended I recently had a complete replacement of a large L-shaped flat roof, including multiple skylights, parapet walls and a number of other complexities. Having previously had the roof repaired twice by other companies and still experienced leaks, I decided enough was enough and wanted the whole roof stripped back and replaced by a reputable company. I’m so glad I found Pro Active Flat Roofing. I was massively impressed with the whole process from beginning to end. Trish was fantastic from the initial booking of the survey, keeping me regularly updated throughout. Steven carried out the initial survey and was incredibly thorough, talking me through everything and patiently answering my many questions. The quote came through quickly and was detailed, which gave me a lot of confidence in the company. Damian and Steven then worked with me on value engineering to get the project within my budget, without compromising on the quality of the solution. The whole team was also incredibly understanding when I unexpectedly needed to delay the project by a month. The operations and logistics were equally impressive. Becky and the team kept everything organised, with the scaffolding, skips and roofing team all arriving exactly when they were supposed to. I received regular updates throughout the project, including daily photographs, and any queries I raised were dealt with quickly and effectively. The team on the ground were brilliant. They were polite, professional, hardworking and clearly took a huge amount of pride in their work. They were real perfectionists and kept me updated throughout, including flagging any potential issues and discussing them with me before proceeding. The quality of the finished roof is excellent. It looks really smart and, most importantly, we’ve since had some torrential rain and it finally doesn’t leak! After years of dealing with problems, that is a huge relief. They also went above and beyond by sorting out an issue that was outside the scope of the project while I was away on holiday, which I was incredibly grateful for. I would have absolutely no hesitation in recommending Pro Active Flat Roofing. I’ve come to realise that you really do get what you pay for. Having previously tried to save money on cheaper repairs and ultimately paid twice, I only wish I had found Pro Active sooner. A fantastic company, an excellent team and a first-class job. Highly recommended.

I engaged Proactive to replace a flat roof for me after being expensively let down mid-job by another 'firm'. To say that Proactive are highly professional would be to understate the matter - they are simply excellent. An initial survey, followed by a technical survey led to the production of the time and materials schedule and all associated documentation. All costs were itemised up-front and a price for the whole job agreed. I had my own (attractive and intelligent) project manager allocated and she kept things on track and kept me informed. Everything was properly co-ordinated, including materials delivery, skips and scaffolding - thanks, Becky. The guys who did the work, Jake and Rocco, were first-rate and fun to have around as well as working like beavers on some of the hottest days of the year. Once the job was done it was re-inspected by the relevant managers for any snagging issues before being signed off. The guarantee is first-rate, and I have a client folder with dozens of photos showing the work progression at the end of each day. Overall, I could not be happier with this. Well done, PRF.

Having been let down badly with poor workmanship. I contacted Proactive Flat Roofing After a very thorough survey of my roof by Mr Stephen Day, it was decided that the only option I had was to get the roof redone. After getting another report from an independent surveyor who also condemned the roof as not fit for purpose. I accepted the very concise written quote from Proactive Flat Roofing.I also received a very good guide booklet explaining in detail their product and their guidance to getting your roof done. From the first site visit by Mr Stephen Day and then to the great communicational and organisational skills of the support team Becky,Cloe,Yvonne,Charlotte,and Carla. To the Skill and Professionalism of Dave the Roofing Technician. I genuinely believe that I could not have contracted a more dedicated to customer satisfaction driven team of people. If you are getting your flat roof done, do not go down the route I did by NOT checking the roofing businesses certification and accreditation certificates. To get a "Proper Job" done Think about giving PROACTIVE FLAT ROOFING A CALL

The team are highly professional. Paull helped us sort a roof on a house we had recently purchased that had some major construction flaws. Communication from the start was outstanding. Every member of staff we dealt with were very knowledgable and answered all our questions. Would certainly recommend, quality work.

A very professional organisation that attended site at agreed times to investigate our fault and came up with the required solution. The operatives were polite and friendly and kept us constantly informed of their progress. They kept disruption to a minimum and tidied up after them selves. A pleasure to deal with and would highly recommend.

Proactive Flat Roofing undertook a roof refurbishment project that I was overseeing in Battersea. They were extremely professional, co-operative and adaptable (we had a few obstacles to overcome due to difficult tenants) and their workmanship was excellent. Overall very pleased and wouldn't hesitate to recommend them on any future suitable projects

FAQs: Vanguard CladGuard™ Coating for Commercial & Industrial Roofs

Is coating suitable for my commercial roof?
Yes. If the structure is sound but the surface is worn or suffering from corrosion, coating is often a great alternative to full replacement… and far less disruptive. Coating provides a uniform membrane over complex roof shapes and profiles, so no matter the roof, we can offer effective coating.
Absolutely. We’ve coated roofs on shops, schools, warehouses, care homes and more. It’s ideal for any building that needs fast, cost-effective protection.
We can target high-risk areas like seams, laps or corroded ends without having to coat the entire roof – saving time and money.

Our systems can last between 10 and 25 years depending on the type of product most suitable for your specific roof. We’ll recommend the right system for your needs and budget.

Very little. We keep noise and disruption to a minimum. Most clients can stay in the building during the work, even in the case of businesses and busy premises.

Safety and sustainability is a priority with our coating solution. Many modern systems (like ours) offer high fire ratings. In fact one of the systems we install is the only AA fire-rated roof coating available under BS 476-3. And on the environmental perspective, coating can even help lower your building’s carbon footprint by helping you maintain temperatures and use less power to heat and cool.

So coating can be both a safe and sustainable way to protect your roof and keep your building safe.
