Why Invest in Metal Roof Waterproofing?

Metal roofs are a cornerstone of South African architecture, valued for their affordability, durability, and versatility in residential, commercial, and industrial settings. However, South Africa’s extreme weather—characterised by heavy rainfall, scorching UV exposure, and temperature fluctuations—poses significant challenges.

Corrugated iron, IBR, Kliplok, and zinc roofs are particularly susceptible to rust, leaks at screw lines and joints, and damage from thermal expansion. Without proper waterproofing, these issues can lead to corrosion, water ingress, and costly structural repairs.

At SealPro Coatings, our metal roof waterproofing services address these vulnerabilities with a comprehensive approach that combines advanced materials and expert craftsmanship.

Our key benefits include:

Leak Prevention

StretchSeal embedded with Flex create seamless, flexible membranes that seal screw lines, joints, and overlaps, preventing water ingress even during heavy downpours.

Rust and Corrosion Protection

Referro rust converter and SteelPro 3in1 halt corrosion, protecting rusted metal roofs and extending their lifespan.

UV and Thermal Resistance

SteelPro 3in1 delivers a UV-stable, high-gloss finish that reflects harmful rays and adapts to thermal expansion, reducing wear and energy costs.

Customised Solutions

We tailor our services to suit corrugated, IBR, Kliplok, or zinc roofs, addressing specific needs like low-pitch roof sealing or solar bracket waterproofing

Long-Lasting Durability

Our products come with a 10-year warranty, subject to regular maintenance, ensuring lasting protection.

Offering transparent pricing, detailed proposals, and free inspections, we ensure leak-proof, rust-resistant finishes that enhance property durability and value in South Africa’s harsh climate.

Our Expert Metal Roof Waterproofing Process

SealPro Coatings approved applicators follow a meticulous, seven-step process to ensure your metal roof is thoroughly protected against South Africa’s challenging conditions:

1. Comprehensive Inspection

We begin by inspecting your roof for loose or missing screws on sheeting and ridgelines, loose flashings, damaged sheeting, compromised mounting points for solar panels or other equipment, and signs of rust. This thorough assessment identifies all potential failure points, ensuring no issue is overlooked.

2. Rust Treatment and Sheeting Replacement

Light rust is removed with a wire brush and treated with Referro rust converter to neutralise corrosion. For heavily rusted or damaged sheeting, we replace the affected sections with new, high-quality sheeting to ensure a robust surface for waterproofing.

3. Securing Fasteners

Loose or missing roof screws are replaced with Class 3 self-seal roof bolts on sheeting, flashings, and ridgelines. These bolts provide a watertight seal, preventing leaks at critical fastening points.

4. Sealing Joints and Screws

We apply StretchSeal and Flex to seal screw lines, joints, and repaired sections, creating a flexible, impermeable barrier. For low-pitch roofs (below 5 degrees), we may also seal overlaps with our stretch membrane waterproofing system to enhance protection against water pooling.

5. Degreasing and Surface Preparation (Recommended Extra Step)

The roof is degreased using a high-pressure washer or handwashing to remove dirt, grease, and contaminants.

6. Priming with Referro (Recommended Extra Step):

For roofs with moderate to heavy rust or old Chromadek surfaces, we apply Referro to convert rust and prime the surface in one step. Referro also ensures excellent adhesion for Chromadek roofs, preventing coating failure and preparing the surface for the final topcoat.

7. Final Coating with SteelPro 3in1 (Recommended Extra Step)

We apply two coats of SteelPro 3in1, a high-performance product that serves as a rust inhibitor, primer, and topcoat. This UV-stable, high-gloss finish protects against South Africa’s extreme weather, resists corrosion, and enhances the roof’s aesthetic appeal.

Why Metal Roof Waterproofing Matters in South Africa

South Africa’s climate places immense stress on metal roofs. Heavy rainfall, can exploit weak points like screw lines or joints, leading to leaks that damage interiors and equipment.

Intense UV radiation accelerates rust and coating degradation, while thermal expansion causes joints to shift, increasing vulnerability. Waterproofing maintenance not only prevents these issues but also extends the roof’s lifespan, saving property owners from costly replacements.

Our use of Referro, StretchSeal, Flex, and SteelPro 3in1 ensures a tailored solution for every metal roof type.
