Commercial Roof Coatings

UK Specialists in Industrial Roof Refurbishment and Protective Coating Systems

Commercial roof coatings are liquid-applied systems used to waterproof, protect and extend the life of industrial and commercial roofs. They prevent leaks, halt corrosion, seal joints and typically provide 10–20+ years of additional service life without removing the existing roof structure.

Total Cladding & Roofing Ltd installs systems from leading UK manufacturers, including Gyromax, HD Sharman (Delcote™ / Seamsil™), Alltimes Coatings, Rooflock and Liquasil. We provide nationwide surveys, specifications and full installation for commercial and industrial buildings.

What Is a Commercial Roof Coating?

A commercial roof coating is a liquid membrane applied over an existing roof surface to improve waterproofing, durability and resistance to weathering. Once cured, it forms a seamless, fully adhered layer that reinforces the current roof and extends its lifespan.
These coatings are commonly used on metal sheet roofs, asbestos cement roofs and flat roofs with ageing waterproofing systems.

Benefits of Commercial Roof Coatings

• Lower cost than full roof replacement

• Minimal disruption to operations

• Extended roof life of 10–20+ years

• Enhanced waterproofing performance

• Corrosion protection at cut edges, fixings and end laps

• Improved building appearance with a uniform finish

• Reduced heat gain when reflective or UV-stable coatings are used

• Suitable for a wide range of commercial and industrial roof types

What Types of Roofs Can Be Coated?

• Metal profile sheet roofs (trapezoidal and corrugated)

• Gutters, rooflights and complex detailing

Suitability is determined through a detailed roof survey.

Commercial Roof Coating Process

1. Consultation and Desk Study

Review of photos, existing reports, drawings and building information.

2. On-Site Roof Survey

Inspection of the roof surface, moisture readings, access considerations and photographic documentation.

3. Specification and Quotation

Selection of the appropriate manufacturer-approved coating system with warranty options.

4. Cleaning and Surface Preparation

Includes washing, rust treatment, cut-edge corrosion repair, sheet repairs and joint sealing.

5. Application of the Coating System

Installed to manufacturer standards with the required film thickness, coverage rates and detailing.

6. Final Inspection and Warranty Issue

A photographic record is provided and the manufacturer warranty is arranged where applicable.

Commercial Roof Coatings vs Roof Replacement

Coating a roof is significantly more cost-effective than replacing it. It reduces labour, waste disposal and disruption while extending roof life.
Replacement is normally only required when the roof structure has severe corrosion, widespread perforation or significant material breakdown. This is assessed during the survey.

How Long Do Commercial Roof Coatings Last?

Most systems last between 10 and 20+ years, depending on:

• Roof condition

• Coating type

• Installation method

• Exposure to weather

• Maintenance

Approved systems from major manufacturers offer extended warranties when installed correctly.
