Commercial Roof Coating for Rusted Roof

Rusty Metal Roof Coating Options

When the City of Richmond, British Columbia, came to Inland, they feared the worst. With a high degree of rust and multiple leaks at seams and penetrations, they believed a tear-off was the only option for their 20-plus-year-old commercial metal roof. Knowing how disruptive and costly a tear-off would be for operations, the city searched for an alternative.

An inspection confirmed the roof was structurally sound and an excellent candidate for a fluid-applied membrane. Our sales representative, Bob Furness, partnered with Cascade Roofing & Waterproofing to restore the commercial roof while meeting both budget requirements and long-term performance needs.

Rubber Roof Coatings Restoration Process

Instead of replacing more than 17,000 square feet of metal roofing, we developed a restoration plan using a four-step elastomeric roof coating system backed by a 10-year system warranty. The process included:

  • Power washing and wire brushing the surface
  • Surface preparation, including:
    • Sealing fasteners
    • Prepping horizontal seams
    • Prepping vertical seams
    • Addressing penetrations
  • Applying a corrosion-resistant top coat
  • Final cleanup using mineral spirits

The Benefits of Restoring a Metal Roof with Elastomeric Coatings

The SEBS rubber roof coating system required no special primers, making the application fast, easy, and efficient. These ENERGY STAR-rated elastomeric coatings deliver up to 87% solar reflectance, high elongation and tensile strength for long-term durability and corrosion protection.

Before
After

After application, our team and City of Richmond personnel inspected the roof to confirm it met warranty standards. The city avoided a complete tear-off and gained an affordable solution that significantly extended the life of their metal roof.
