Gravel Roof Restoration Just Got a Whole lot Easier

By Cass Jacoby.  

The AlphaGrade™ Restoration System is designed to be a quick, non-intrusive and environmentally friendly alternative to replacing aged gravel-surfaced built-up roofs. 

Looking for the perfect restoration solution for aging gravel-surfaced roof systems? Allow us to introduce Tremco Roofing’s  AlphaGrade System, the first ever bio-based, two-component, 100% solids, low VOC, polyurethane liquid applied restoration system for existing gravel-surfaced, built-up roofs (BUR). This bio-based technology locks down rock to transform a roof from aged to a bright white sheen with three layers of waterproofing protection. 

As a gravel-surfaced roof gets older, the rock loosens, becoming dangerous in high winds to objects and people below. Traditionally, the options to remedy this were high-cost and labor intensive or a short-term solution like foam recovers and asphalt-based flood coats. The unique AlphaGrade restoration system offers an alternative that fully restores problematic gravel rooftops without incurring unnecessary costs, environmental waste or occupancy disturbances. Here is how: 

3 steps for a simple gravel roof restoration 

Step one - Tremco’s process begins with safely removing any loose gravel and debris; embedded gravel stays in place. After that, a Tremco approved applicator will clean and prepare the roof surface for an application of AlphaGrade.  

Step two – Apply AlphaGrade leveling coat, which seals the gravel in place and provides the initial layer of waterproofing. 

Step three - Finish with the environmentally friendly AlphaGrade Base and Top Coats for additional waterproofing and to offer a bright, highly reflective finish that protects the roof and reduces energy usage. On average, Tremco reports that the three coats combine to provide over 300 mils of waterproof protection in addition to the underlying multi-ply BUR system. 

The entire process is typically completed in a few days, with little disruption to the building occupants, as these products have no smell and do not require as much equipment or steps as a roof replacement. 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. 

Conclusion 

Ultimately, the AlphaGrade restoration system is another product demonstrating Tremco’s commitment to manufacture and deliver sustainable solutions and services that perform at the lowest possible life-cycle cost. If you have an aging gravel-surfaced BUR, why replace it?  Look to the future with the AlphaGrade restoration system and extend the life of your roof today
