Rust. It’s a serious threat to industrial and commercial roofs. Left untreated, it can compromise structural integrity, cause leaks, and lead to costly damage. At Unitech SA, we specialise in industrial roof repairs, ensuring your business stays protected. Here’s how we tackle rust on industrial roofs with precision and expertise.

Why Winter is the Best Time for Roof Repairs
As winter approaches and the heavy summer rains subside, now is the perfect time to address rust and damage on your industrial roof. With drier conditions ahead, repairs can be completed without weather disruptions, ensuring your roof is in peak condition before the next rainy season hits. Fixing rust now prevents leaks and structural issues when you need your roof to perform its best.
Step 1: Safety First – A Secure Approach
Safety is our top priority before we begin any repairs. Our team follows strict safety protocols, using personal protective equipment (PPE) and secure access systems to ensure a risk-free work environment

Step 2: Surface Preparation – Clearing the Way for Repairs
A clean surface is essential for effective rust treatment. We remove dirt, debris, and loose rust using high-powered tools, including pressure washers and industrial brushes. This allows us to assess the extent of the damage properly.
Step 3: Identifying Problem Areas
After cleaning, we conduct a thorough inspection to pinpoint rusted sections, corrosion, and any structural vulnerabilities. This step ensures that we apply the correct treatment for lasting results.
Step 4: Professional Rust Treatment
We use industry-leading methods to treat rust effectively:
- Rust Converters – These chemically stabilize rust, preventing further spread and preparing the surface for coating.
- Rust Inhibitors – These create a protective layer, preventing new rust formation and extending the roof’s lifespan.
- Protective Coatings and Paints – We apply industrial-grade rust-resistant coatings to shield your roof from future corrosion and environmental exposure.

Step 5: Application Process – Precision Matters
Following manufacturer guidelines, we apply coatings in multiple thin, even layers, allowing each coat to dry properly. This ensures maximum adhesion and long-lasting durability, providing superior protection for your roof.
Step 6: Ongoing Maintenance & Prevention
Our job doesn’t end with treatment. We offer ongoing maintenance services to ensure your roof remains in top condition:
- Regular Inspections – Scheduled assessments help detect early signs of rust and address them proactively.
- Cleanliness Maintenance – Keeping the roof free of debris prevents rust from forming in the future.
- Touch-Ups & Repairs – We provide periodic maintenance to ensure long-term durability and performance.
