Rusty Metal Roof Coating Options

When the City of Richmond, British Columbia, came to Inland Coatings, they feared the worst. With a high degree of rust and multiple leaks at seams and penetrations, they thought 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 looked for another option. That’s when an inspection deemed the roof to be structurally sound and an excellent candidate for a fluid applied membrane. Our sales representative, Bob Furness, teamed up with Cascade Roofing & Waterproofing to restore the commercial roof, meeting both budget requirements and long-term needs.

Rubber Roof Coatings Restoration Process

Rather than replacing a more than 17,000 square-foot metal roof, we developed a plan of action using our 4-step elastomeric roof coatings backed by a 10-year system warranty.

Our process entailed:

• Power washing and wire brushing the surface
• Prep the surface area including:
  • Sealing fasteners
  • Prepping horizontal seams
  • Prepping vertical seams
  • Addressing penetrations
• Applying our corrosion-resistant RC-2013 base coat and RC-2014 top coat
• Cleaning up with mineral spirits

The Benefits of Restoring a Metal Roof with Elastomeric Coatings

The SEBS rubber roof coating process that we used required no special primers, so it was quick, easy and efficient to apply. Our ENERGY STAR-rated elastomeric roof coatings also offer up to 87% solar reflectance, 500% elongation and 1,500 psi tensile strength for long-term durability and corrosion protection.

After the application process was complete, our team, along with City of Richmond personnel, inspected the roof to ensure that it met the application standards for warranty approval.   Not only was the city able to avoid a complete tear-off and installation of a brand-new roof, but we also provided the client with an affordable solution that dramatically extended the life of their metal roof.
