Tremco Roofing’s AlphaGrade Restoration System was designed for and proven to restore aging but still functional gravel-surfaced built-up roofs (BUR). After repairing a restorable roof and removing loose gravel, three layers of bio-based, liquid applied, cold waterproofing protection are installed:
• AlphaGrade, a leveling coat that locks the remaining gravel in place
• AlphaGrade Base Coat
• Highly reflective, weather-resistant and restorable AlphaGrade Top Coat
Because all restoration layers are liquid, installation requires much less material and equipment than replacing a built-up roof. In addition, there is little impact on those using the building and no odor.
