Cementitious roofing has proven to brilliantly improve the life expectancy of SPF roofs; however, with the way UV rays break down the roof’s layer of acrylic-modified cement over time, when it comes to restoring the roof, most coatings simply cannot bond to the aged surface. Now with the early cementitious projects approaching their end of life, building owners are seeking successful coating options for reviving them.

Ecodur's extreme adhesion has proven to bring these roofs back to life indefinitely — in instances where no other coatings performed with long-term performance or longevity! Its unique chemistry gives Ecodur its incredible ability to stick to exceptionally slick surfaces, and to even bond or partially bond in others.

Cementitious Roof

Every year, more than one million Americans are diagnosed with skin cancer, making it the most common form of cancer in the country. In the United States, one person dies of skin cancer every hour of melanoma every year. Not surprisingly UV also ravages unprotected inanimate surfaces, whether they be exposed lumber, car paint, fabrics, plastics or roofs. This case study focusses on cementitious roofing in the heart of the US high UV radiation belt.

Foam and Cementitious Roof

Spray polyurethane foam (SPF) roofing is a popular choice in hot sunny environments. With R values up to R-6.5 per inch of thickness, an SPF roof can be a very effective way to insulate a building and keep utility costs low. However, SPF itself has no resistance to damage from UV rays and can be ruined in less than 5 hours of direct exposure. While many options exist for protecting SPF from UV exposure, cementitious roofing is one of the longest-lasting and toughest available. Though cementitious roofing offers many benefits, it presents significant challenges as it approaches the end of its life.
