AlphaGuard BIO Liquid Applied Roof Restoration Solution:

AlphaGuard™ BIO Liquid Applied Roof Restoration System

Sometimes, the easiest choices are really easy!

Gravel-surfaced built up-roofs (BUR) are tough but they still deteriorate. Until now, all you could do was replace the roof (expensive, labor-intensive, messy, disruptive or restore it with aging, limited technologies.

No more.  Tremco’s AlphaGrade restoration system can restore these roofs with a new, environmentally responsible waterproof covering while reducing stress for building occupants.  Download our AlphaGrade restoration system flyer to learn more.

After we determine that a BUR roof is suitable for restoration, loose gravel is vacuumed up and necessary repairs made. Then we apply three layers of bio-based weatherproofing protection:

• AlphaGrade, a leveling coat that locks in the gravel.
• AlphaGrade Base Coat
• Highly reflective AlphaGrade Top Coat

Easy as 1, 2 3.  There is little disruption to those using the building, no risk of fire, almost no smell, and most importantly, you'll have fully restored roof that will perform for you for decades.

and you AlphaGuard BIO benefits don't stop there.  This solution has excellent properties to help keep your existing roof performing at a high level.  AlphaGuard BIO carries a variety of product listings including Cool Roof Rating Council (CRRC), Florida Building Code, UL, and USDA BioPreferred, and is FM Approved as a maintenance coating only, not for use as a roof cover.   It's easy to maintain and repair, which is good for sustainability over a long period of time, designed to perform extremely well in third party laboratory hail testing and cold weather, and resists mold, mildew and fungus.
