A suburban school outside of Atlanta, Georgia had a roof system that was leaking and nearing the end of its service life. The roof system included six metal roofs totaling over 60,000 square feet in addition to another 30,000 square feet of TPO. While a complete tear off and replacement of the roofs was one option, the school system was interested in alternative solutions that would be less costly.
An ALDOCOAT acrylic roof coating system was prescribed as the solution, utilizing three ALDOCOAT standard products and a custom color solution for the metal roof.
ALDOPRIME 710 was spray applied at a rate of one gallon per 100 square feet. This provided a proper anchor to maximize adhesion of the acrylic base and top coats. All areas of suspected water penetration were then treated with ALDOSEAL 750 Sealant. Once this was completed, a coat of ALDOCOAT 374 Gray base coat was spray applied and allowed to cure for 24 hours. Finally, the ALDOCOAT 374 Malted Milk custom color was applied.
The ALDOCOAT acrylic system was an ideal alternative to roof replacement and restored the roofs to their original color. The ALDOCOAT 374, a CRRC approved product, extended the service life of the metal roof system for another 10 years and its reflective Malted Milk color reduces heating and cooling costs. This was accomplished for 70% less than the cost of a tear off and new installation. Additionally, there was no roof tear off waste added to the local landfill. The project was another example of quality low cost alternative to expensive, unnecessary and wasteful roof replacement.
