Metal Roof Cladding Coating Systems

To keep your property protected, you need to ensure that the metal roof over it is overlaid with waterproof sealant formulated specifically for specific metal roofs that will keep it free of corrosion and damage. We use metal specific protective sealants. For example, for tin roofs, we use specialist galvanized roof sealants only.

At Storm Coatings, we ensure that your metal roof protective coating is applied throughly and evenly to make it fully sealed to keep it safe from leaks and heat stress. We paint your metal roof panels for improved looks of the property.

Depending on the roof and the coating treatment selected, you receive 10 to 25 years’ guarantee on the work delivered by us.  This also ensures that your metal roof coating cost per square metre pays in the longer run as you don’t have to incur cost of recoating metal roof anytime soon again.

Metal Roof Coating Solutions

Our metal roof coating systems are formulated specifically for profiled steel and aluminium cladding. Whether you have a corrugated metal roof, trapezoidal profile, or standing seam system, we apply high-performance protective coatings that seal against moisture, prevent corrosion, and restore the appearance of weathered cladding. All coatings are applied on-site with no need to strip the existing surface.

Why Metal Roof Cladding Deteriorates

Metal roof cladding is durable, but over time exposure to UV, rain, temperature cycling, and atmospheric pollutants breaks down the original factory-applied coating. Cut edges and fixings are the first areas to show corrosion, followed by the sheet face. Without treatment, corroded metal cladding leads to leaks, structural weakening, and eventually the need for costly full replacement. A metal roof cladding coating applied at the right time can extend the roof life by 20-25 years at a fraction of the replacement cost.

Metal Roof Waterproofing Process

Our metal roof waterproofing process begins with a thorough survey to assess the condition of the existing cladding, fixings, and flashings. We then clean and prepare the surface, treat any cut edge corrosion, replace degraded fixings, and apply a multi-coat protective system. The finished coating provides a seamless, weather-tight barrier that withstands the most demanding UK weather conditions.

Frequently Asked Questions

How long does a metal roof coating last?

A properly applied metal roof coating system typically lasts 20-25 years. We use high-performance liquid waterproofing systems specifically designed for metal substrates.

Can you coat a rusted metal roof?

Yes — provided the metal is structurally sound. Surface rust is removed during preparation, and specialist primers are applied to stabilise any remaining corrosion before the waterproof coating is applied.

What types of metal roof can be coated?

We coat all common metal roof types including profiled steel sheets, standing seam roofing, composite panels, corrugated iron, and aluminium roofing. Each substrate is treated with the appropriate primer and coating system.

Will coating my metal roof stop condensation?

A roof coating alone will not solve condensation problems, as these are caused by inadequate ventilation or insulation. However, we can advise on condensation solutions as part of a roof refurbishment project.

How much does metal roof coating cost per square metre?

Costs vary depending on roof condition, access, and the coating system specified. We provide free surveys and detailed quotations. As a guide, coating is typically 50-70% less than full re-cladding.
