BRANDS WHO PUT THEIR TRUST IN MELBOURNE PROTECTIVE COATINGS

Slash Roof Maintenance Costs with Lasting Waterproofing

Leaks, ponding water, and storm damage can take a huge toll on commercial buildings. Water seeping through your roof doesn’t just damage structures—it disrupts business and increases maintenance costs. If left untreated, small issues can become big problems that cost thousands to repair.

Our commercial roof waterproofing Melbourne services offer a proven, preventative solution. Unlike patch repairs that fail over time, our seamless waterproofing solutions create a long-lasting protective barrier over your existing metal roof. The application process is fast—often completed in days—and designed to minimise disruption to your business operations. With warranties ranging from 5 to 20 years, you’ll have peace of mind knowing your roof is protected for the long run—without the ongoing hassle of temporary fixes. Whether you manage a retail store, warehouse, or industrial site, we’ll help you protect your assets from leaks, rust, and weather extremes.

Superior Waterproofing That Protects Your Business

Total Leak Prevention

Our waterproofing coatings form a seamless, flexible barrier that stops water from penetrating your roof at its most vulnerable points. Whether it’s joints, seams, or ageing sections, we apply a consistent layer that blocks rain, standing water, and seepage. Designed for Melbourne’s unpredictable weather, our solution gives your roof the defence it needs all year round.

Extend the Life of Your Roof

Waterproofing helps prevent leaks while extending the long-term performance of your roof. Our coatings protect against rust, rot, and membrane failure caused by constant water exposure. This allows you to avoid early roof replacement and get more value from your original investment.

Save on Emergency Repairs

A reactive approach to roof leaks often means costly callouts and damaged interiors. By waterproofing proactively, you eliminate the cycle of patch jobs and emergency repairs. Our coatings provide long-lasting protection, saving you time, money, and unnecessary stress.

Minimal Disruption

We understand your business needs to keep running. That’s why our team coordinates closely with you to minimise downtime and disruption. Most installations can be completed while your operations continue as normal, with safety and cleanliness as our top priority.

Backed by Warranty

We stand behind our work. Our waterproofing systems come with up to 15 years of manufacturer warranty and a 6 year workmanship guarantee. That means your roof is protected long after the job is done, and so is your investment.

Fully Compliant

Our coatings meet ISO 9001:2015 standards and are low in VOCs, making them safe to apply and environmentally responsible. Whether you're operating in retail, hospitality, or manufacturing, our products comply with all applicable safety and environmental regulations.

Fits All Commercial Properties

From shopping centres to schools, factories to strata buildings, we work on it all. No matter your property’s size or structure, our team delivers a customised waterproofing plan that suits your needs and keeps your building protected.

Case Study

Tottenham Factory (Florsheim)

Project type: Commercial - Sub-Contracted
Project Outline: Waterproofing Roofing Membrane

Florsheim’s primary Melbourne distribution centre in Tottenham was experiencing severe roof leaks, resulting in merchandise losses exceeding a million dollars. A full roof replacement was not a viable option due to its high cost and the potential business disruption. Melbourne Protective Coatings (MPC) was subcontracted by TOPPS Australia to collaborate with Programmed in applying a high-performance waterproofing membrane across two expansive roofs, covering over 10,000m2.

Harry and the team completed a commercial roofing project at our office last week. They were all fantastic to deal with, updating us throughout the works, and put in a lot of care to make the process as seamless as possible. Thanks guys - couldn't recommend more highly!
- Emma Bester
The team at Melbourne Protective Coatings went above and beyond my expectations. Their team were very easy to deal with, thorough, and professional in their approach to repairing, sealing and coating all of our rusted box gutters, and entire upper roof of our office warehouse. The solution has effectively prolonged the life of our roof for at least the next 10 years. Thank you Harry and team.
- Brad Shannon
I am based in Brisbane and contacted Melbourne protective coatings to seal a small retail center roof that had multiple leaks and rust. The guys were a pleasure to deal with, did everything they quoted with a minimum of fuss and on time. We will definitely use them again as the job was perfect.
- Russell Bowkett
Harry and his team professionally treated and sealed our rusting metal roof on a block of 6 units.
It saved us replacing the roof at a fraction of the cost and they give a 10 year guarantee and possibly lasting another 20 years.
We were also prepared to replace the gutters but surprisingly Harry offered to treat and seal them at no extra charge.
Such amazing value and generosity from this easy to deal with company.
I would highly recommend them anytime.
Thanks Harry and Team
- Joe Zammit
Harry and his team at Melbourne Protective Coatings did an amazing job to restore our rusty roof using their anti-corrosion waterproof membrane. Harry is an awesome guy and a pleasure to work with. From discussing options, putting together a quote, finding a block of warm, dry days in the middle of winter to start the work, and even doing some extra painting for free, Harry and his team made this so easy. The quality of their work is excellent and was so much cheaper than a new roof. I would highly recommend Harry and his team for any painting work, especially if it’s something technical like properly restoring a rusty roof.
- Daniel Broughton
Harry and his Team did an amazing job restoring the rusted roof on our apartment block roof saving owners $$$$ on an entire roof replacement. Harry liaised with the OC walking us step by step through the process.

MPC were incredibly communicative and responsive to any a needs of owners and tenants. From start to finish they went above and beyond to provide and deliver a high quality finish and customer service.

Would highly recommend MPC for any painting project, and will be using them for all our future painting works.

Thanks guys! You’re legends!
- Laura White
Melbourne Protective Coatings recently repaired a retail roof I manage, and we haven’t had a single leak since. Excellent work and a budget-friendly alternative to a full replacement. Highly recommend Harrison and his team.
- Bertrand Bienvenu
We got Melbourne Protective Coatings to do a restoration job before it became a replacement job on our roof. The aim was to stop some leaks, prevent further corrosion and to provide some thermal insulation. We got all that.

Harry turned up on time a gave us a clear explanation of the process and time required. The guys turned up on time and were as non-intrusive as they could be. They also communicated each step of the way what would be done and how it would effect us. A pleasure to work with on our restoration. I could not recommend them highly enough.
- Dale Thompson
We engaged Melbourne Protective Coatings to undertake a large project for us that had been problematic for quite some time and had several other companies tangled in confusion and despair.

Melbourne Protective Coatings are 100% professional in every way, they put together a strategy to carry out the project and outperformed my expectations everyday. Anyone associated with the company while carrying out the project was professional and respectfully a pleasure to work with.

We have been in construction a long time and it’s rare to come across a company of motivated professionals like Melbourne Protective Coatings that perform so well in their given field.

I can honestly say, they come highly recommend by me personally and from our company.

Looking forward to working with them again in the future.

Innovative Waterproofing Solutions, Backed by Experience

Step 1

Assessment & Preparation

We begin with a detailed roof inspection to identify structural vulnerabilities, signs of wear, and existing leaks. The surface is then pressure cleaned to remove dirt, moss, old coatings, and contaminants. This step ensures strong adhesion and reveals hidden issues that need repair before coating.
Step 2

Repair & Priming

We carefully patch all penetrations, fix damaged flashings, and treat corroded or weak areas. Once repairs are complete, we apply a specialised primer suited to your roof type—metal, concrete, or membrane—to ensure optimal bonding and long-term durability of the waterproof coating.
Step 3

Waterproof Coating Application

We apply multiple coats of high-performance waterproofing products using spray, brush, or roller, depending on the roof’s size and access. Each layer is allowed to cure fully before the next is applied, building a seamless, UV-resistant, watertight barrier over the entire surface and gutters.
Step 4

Final Inspection & Ongoing Support

After curing, we perform a final inspection to ensure quality and consistency across the entire roof area. You’ll receive comprehensive warranty documentation and tailored maintenance recommendations to maximise system lifespan and ongoing leak protection. Our team remains available for support long after the job is done.

Safety First

Melbourne Protective Coatings are unwavering advocates for both exceptional workmanship and uncompromising safety standards. In every roofing project we undertake, we now incorporate live-edge guard‑rail systems to maintain compliance with Worksafe Victoria's mandatory fall-protection measures-especially on pitched roofs.

We utilise a variety of safety controls for efficient and secure roofing and painting operations:

All roofing division employees are trained by the Positive Training Academy and hold current Working at Heights (RIIWHS204E) tickets.

MPC holds full WorkCover registration (16881750) for all employees and is fully insured with Allianz public liability coverage ($20 million, policy 118U357018BPK), providing complete peace of mind.

Projects on pitched roofing profiles always include specialised anchor points along with live-edge guard‑rails-a form of temporary rail system-to ensure passive fall-prevention as required under Worksafe regulations.

Worksafe expressly mandates physical edge protection on sloping roofs where falls from height (≥ 2 m) present a risk

We prepare and follow detailed Safe Work Method Statements (SWMS), in line with high-risk construction protocols, ensuring all tasks are planned with effective supervision

By combining the correct use of live-edge guard‑rails with rigorous training and anchored systems, Melbourne Protective Coatings not only achieves top-quality results but also safeguards every team member - fully aligned with Worksafe Victoria's fall-prevention mandates.

Specialised anchor points are used on roofs with pitched profiles!

Frequently Asked Questions About Waterproofing

Do you offer emergency repairs?
Our waterproofing systems are designed for full-roof applications, not quick patch jobs. However, during colder months or in urgent situations, we can apply temporary sealing to help control leaks until full installation can be completed. This gives you peace of mind while you wait for optimal weather conditions.
Can you install it on my roof year-round?
In warmer parts of Australia, yes. But in Victoria, application depends on specific temperature and dew point requirements. We aim for the warmer months for best results, although smaller projects can sometimes proceed during autumn or winter when conditions are mild enough.
Can you waterproof gutters?
Absolutely. Our team applies the same high-performance waterproofing solution to commercial box gutters, sealing joints and cracks and preventing costly replacements. This adds long-term protection against overflow, rust, and structural water damage.
Will my roof leak during installation?
Possibly. We take precautions to limit water ingress, but if your roof already has leaks, some water may enter during pressure cleaning or repairs. We clearly communicate potential risks and can assist with internal paintwork or damage remediation if needed.

How do you stop roof leaks?
Leaks can occur for many reasons, and each type needs the right solution to stop further water damage and protect your roof for the long haul:

Small penetrations: For tiny holes or cracks, we use a thick, self-sealing coating that spreads smoothly and forms a watertight seal without needing additional reinforcement.

Medium penetrations: When there’s more damage, such as screw holes or small gaps, we reinforce the area by embedding specialised sealing fabric into the first coat before applying additional layers.

Large penetrations: Larger holes or damaged sections are addressed with custom-cut repair patches. These are sealed in place using multiple coats of protective waterproof coating for added strength and durability.

Extra-large penetrations: If a section of your roofing sheet is beyond repair, we remove and replace it with new material before sealing the area with protective coating. In more complex cases, a qualified roof plumber may be brought in—either your own or one we can recommend.

Download our roofing brochure to see real examples of how we tackle each scenario and keep roofs watertight.

What’s the difference between your service and a roof plumber?
There’s a clear distinction. Roof plumbers usually handle physical roof repairs, flashing installations, or temporary fixes using materials like silicone and tape—often at a higher cost and without long-term protection. Our waterproofing system is designed to coat the entire roof and gutter area, delivering a like-new, fully sealed surface that restores waterproof performance. Unlike quick fixes, our approach provides lasting durability and is backed by warranties for both materials and workmanship. While roof plumbing can be helpful in managing urgent issues, we offer a long-term solution that addresses the root causes of water damage. We value roof plumbers as collaborative partners and are happy to work together when needed to ensure the best outcome for your roof.
Is this cheaper than replacing the roof?
Yes, significantly. Roof replacement is often disruptive and expensive, while our waterproofing system costs a fraction of that and extends your roof’s life by 10 to 15 years. It’s a smart way to protect your investment without major renovation.
What surfaces can you coat?
Our system works on a wide range of commercial surfaces including metal, concrete, encapsulated asbestos, and roofs previously treated with older waterproofing products. If your building has an outdated or deteriorating coating, we can safely prepare the surface and install a modern waterproofing solution designed to perform better and last longer. We’ll assess your roof during inspection and confirm compatibility before beginning any work.
How long does the coating last?
With proper preparation and installation, our systems last between 10–15 years depending on climate and roof condition. Each project includes a product warranty and a 6-year workmanship guarantee, giving you full confidence in durability.
