Why Rust Shouldn't be ignored
Rust is progressive. Once corrosion begins, it continues to spread beneath the surface — weakening metal roofing and structural steel over time.
Exposure to moisture, oxygen, and harsh weather conditions accelerates oxidation. Left untreated, rust can lead to surface deterioration, recurring leaks, structural weakening, and costly repairs.
Repainting over corrosion does not stop it. Without proper treatment, rust will continue to develop beneath the coating.
Professional rust management is about stabilising corrosion, sealing the surface correctly, and preventing further oxidation.
How We Manage Rust
Rust management requires more than surface repair. At Rubber Roofs, every project begins with a detailed inspection to determine the extent of corrosion and assess structural integrity. During this stage, we identify whether affected sheets can be restored or if replacement is necessary, and this is discussed before any work proceeds.
Where restoration is appropriate, we apply a structured rust management system that stabilises active corrosion and seals the surface correctly to restore protection and extend service life.
Approved systems are backed by a 10-year product and workmanship warranty.
Our Rust Management Process
• Detailed inspection to assess corrosion and structural integrity
• Identification of sheets that require replacement before treatment
• Surface preparation to remove contaminants and loose rust
• Application of RostTech™ to convert active corrosion into a stable compound
• Sealing and protection using liquid rubber technology with built-in RostGuard™ rust inhibition
• Long-term barrier against moisture and oxidation

• Experience across residential, commercial, and industrial properties
• Nationwide service capability
frequently asked questions
Can rust be stopped without replacing the entire roof?
In many cases, yes. If corrosion has not compromised the structural integrity of the sheet, it can be stabilised and sealed using a structured rust management system. During inspection, we determine whether restoration is possible or if certain sheets require replacement.
Why does rust return after repainting?
Paint alone does not stop active corrosion. If rust is not converted and stabilised before coating, oxidation continues beneath the surface. This causes bubbling, peeling, and recurring corrosion. Proper treatment requires conversion, sealing, and protection.
What are the signs of rust damage?
Common signs include flaking metal, visible red or brown corrosion, bubbling coatings, thinning sheet metal, recurring leaks, or rust spreading around fasteners and joints. Early detection reduces long-term repair costs.
Do you need to grind rust back to bare metal?
Not always. RostTech™ penetrates and converts active rust into a stable compound, reducing the need for aggressive grinding in many cases. The correct preparation method is determined during inspection.
How long does professional rust treatment last?
Approved rust management systems installed by Rubber Roofs carry a 10-year warranty on product and workmanship, provided the roof is structurally suitable for restoration.
Is rust treatment environmentally safe?
The products used in our rust management system are water-based, environmentally friendly, free from harmful chemicals, and include mould inhibitors.
How much does rust management cost?
Cost depends on the size of the roof, the severity of corrosion, and whether sheet replacement is required. A detailed inspection allows us to provide a structured quotation.

Waited for 2 rainy seasons to pass before posting this review. I had serious problems with a leaky roof. All issues are sorted. Have a skylight in the kitchen that was the bane of my existence, they even managed to stop that from leaking. Very good job and thank you!

We recently utilized Rubber Roofs services on our business commercial building located in Durban Port.
We found Rubber Roofs pricing to be the most competitive when compared to the local competitors in KZN.
Their communication throughout the tender process was instant and informative, which made the award simple for me having to deal with day to day running of the business.
Their integration into our yard safety procedures was seamless.
While they were carrying out the service they communicated status updates and planned ahead well with the maintenance staff on the ground.
The quality of work was impeccable.
I would definitely recommend Rubber Roofs for both private and commercial purposes.

From beginning to seamless end, our experience with Marc, Blessing and the team was only a pleasure. Everyone was professional. We were kept fully appraised of the progress until completion. Each day we received photos of what was happening on the roof. No mess or issues. Team was presentable and tidy. Cost was affordable and guess what? No extra costs. Proper prep work and lots of different steps to the job.
Our old tin roof leaked a lot. This summer I am looking forward to the rain. They get the Golden Buzzer from me.
