AlphaGrade™ is designed to be a quick, non-disruptive and environmentally friendly alternative to restoring aged gravel-surfaced built-up roofs. 

As a gravel surfaced roof gets older, the rock loosens, becoming dangerous in high-winds and below. As a building owner, it is up to you to find solutions for how to lock down the rock while also extending the lifespan of your roof.  

Traditionally, the options to remedy aging gravel surfaced built-up roofing (BUR) are high-cost and labor intensive or a short-term solution like foam recovers and asphalt-based flood coats. However, the perfect restoration solution for aging gravel-surfaced roof systems is here! 

Tremco’s AlphaGrade™ System, is the first-ever bio-based two-component, polyurethane liquid applied restoration system for existing gravel surfaced built-up roofs. This bio-based technology locks down rock and easily glides over gravel to transform a roof from aged to a bright white sheen with a layer of waterproofing protection. 

This unique system offers an alternative that fully restores problematic gravel rooftops without incurring unnecessary costs or occupancy disturbances.  

Additionally, the process is sustainable. Restoration itself is a greener process that reduces landfill waste by preserving existing roofs. The inherent properties of the product are environmentally conscious, made with high bio-content and post-consumer recycled content. Plus, the highly reflective finishes contribute to the reduction in energy usage and the Heat Island Effect. And with low VOC, you won’t have to worry about releasing fumes into the air.  

Conclusion 

Ultimately, AlphaGrade™ is another product committed to Tremco’s aim to manufacture and deliver solutions and services that perform at the lowest possible life-cycle cost. If you have an aging gravel surfaced BUR, look to the future with the AlphaGrade restoration system and extend the life of your roof today. After all, why replace, when you can restore with AlphaGrade ™?
