Long-Lasting Protection for Metal Roofs

Metal roofs are strong, practical and widely used across South African homes, factories, warehouses, farms and commercial buildings. However, constant exposure to rain, UV, heat, temperature changes and corrosion can cause leaks, rust, failed coatings and water ingress over time.

U-Proof metal roof protection products are designed to help seal and protect corrugated and sheet metal roofing systems. With correct cleaning, rust preparation, priming, reinforcement and waterproofing, U-Proof helps create a flexible protective barrier over vulnerable metal roof areas.

Common Metal Roof Problems U-Proof Helps Solve

Metal roof leaks often begin at overlaps, fixings, seams, flashings, rust-prone areas and roof edges. U-Proof helps reinforce and seal these vulnerable details with a flexible waterproofing system.

Rust & Corrosion

U-Proof helps protect prepared metal surfaces when used with the correct primer and waterproofing system.

Leaking Fixings

U-Proof Fibre Filler helps reinforce fixing areas before applying the main waterproofing layer.

Overlaps & Seams

U-Proof helps seal these vulnerable areas and reduce the risk of water ingress.

Failed Roof Coatings

U-Proof Liquid Rubber forms a seamless, flexible membrane over correctly prepared metal roof areas.

Flashings & Ridge Details

Reinforcement and waterproofing help protect these high-risk roof details.

Weather Exposure

A flexible waterproofing system helps protect the roof while allowing for normal surface movement.

Suitable Metal Roof Protection Areas

U-Proof can be used across a range of metal roof surfaces and detailed areas when the roof is correctly cleaned, prepared, primed and reinforced where required.

Corrugated Metal Roofs

Protect corrugated roof sheets against leaks, weather exposure, overlaps and corrosion-prone areas.

Sheet Metal Roofs

Waterproof suitable sheet metal roof surfaces affected by rain, UV exposure and ageing coatings.

Roof Screws & Fixings

Seal vulnerable fixing points where water can enter through loose screws, washers or worn fasteners.

Overlaps & Seams

Reinforce sheet overlaps, seams, joins and transitions where metal roof leaks commonly start.

Flashings & Ridge Caps

Protect flashings, ridge caps, valleys, roof edges and detailed roof connections.

Rust-Prone Areas

Prepare and protect suitable metal roof areas affected by corrosion, surface wear or coating failure.

Recommended U-Proof Metal Roof Protection System

For the best metal roof protection result, focus on rust preparation, adhesion, reinforcement and flexible waterproofing protection.

  • Step 1Inspect the Metal Roof

    Check the roof for rust, loose fixings, damaged sheets, failed coatings, leaking overlaps, flashings, seams and signs of water ingress.

  • Step 2Clean & Prepare

    Remove dirt, dust, grease, loose paint, rust, flaking coatings and unstable material so the surface is clean and sound.

  • Step 3Prime Where Required

    Use the correct primer where needed to improve adhesion and help protect prepared metal surfaces before waterproofing.

  • Step 4Reinforce Fixings, Seams & Problem Areas

    Apply U-Proof Fibre Filler to screws, overlaps, seams, flashings, ridge caps, roof edges and other vulnerable leak points.

  • Step 5Apply U-Proof Liquid Rubber

    Apply U-Proof Liquid Rubber over the prepared and reinforced areas to create a seamless, flexible waterproofing membrane.

  • Step 6Inspect and Maintain

    Allow the system to cure correctly, inspect the finished surface and maintain roof areas regularly to help prevent future leaks and corrosion.

Metal Roof Protection FAQs

Find answers to common questions about protecting metal roofs, sealing fixings, preparing rust-prone areas and using U-Proof products for waterproofing.

Can U-Proof be used on metal roofs?
Yes. U-Proof can be used on suitable metal roof surfaces when the area is correctly cleaned, prepared and primed where required.
How do I waterproof leaking roof screws and fixings?
The area should be cleaned and prepared first. U-Proof Fibre Filler can then be used to reinforce fixing points before applying U-Proof Liquid Rubber over the repaired area.
Do metal roofs need a primer before waterproofing?
Some metal surfaces require priming to improve adhesion and help protect prepared areas. The correct primer depends on the roof condition, coating type and level of corrosion.
Can U-Proof help with rust-prone roof areas?
Yes. Rust-prone areas should be properly cleaned and prepared before applying the correct primer and waterproofing system.
What areas of a metal roof commonly leak?
Common leak points include screws, washers, overlaps, seams, flashings, ridge caps, valleys, gutters and roof edges.
