Commercial Roof Coating for Rusted Roof

city-of-richmond-beforeWhen 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 commercial metal roof that was over twenty years old.

Knowing how disruptive and costly a tear-off would be for city operations, an inspection found  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 instead restore the City of Richmond’s commercial roof, both meeting their 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 to provide a 10-year system warranty.

Our process entailed:

  1. Power wash and wire brush the surface to bring to tight rust finish
  2. Prep the surface area including:
    1. Sealing fasteners
    2. Prepping horizontal seams
    3. Prepping vertical seams
    4. Addressing penetrations
  3. Apply our corrosion resistant base-coat, the RC-2013-M, and the RC-2014-T as the top coat
  4. Clean up with mineral spirits

The Benefits of Restoring a Metal Roof with Elastomeric Coatings

The rubber roof coating process that we used required no special primers so it was quick, easy, and efficient to apply. Our elastomeric roof coatings have up to 87% solar reflectance (Energy Star rated), 500% elongation and 1520 PSI tensile strength for long-term durability and corrosion protection.city-of-richmond-after

After the application process was completed, 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 brand new installation, we provided the client with an affordable solution that dramatically extended the life of their metal roof.
