Urethane Roof System

A versatile, three product waterproof coating system formulated for rejuvenating existing roofs and protecting frequently trafficked roofs requiring high durability and impact resistance. The combination makes up a complete urethane roof system with warranties of up to 20 years.

UF90 GacoMastic

U90 is a fiber reinforced mastic product for use on details and seams.  This eliminates the need for three coarse applications with embedded fabric.  This single component mastic also has a higher viscosity and sag to conform around details and in vertical applications.

U91/U91C Base Coat

U91 is an aromatic urethane base coat for use over most substrates to build the body of the roofing system.  It provides excellent adhesion and tensile performance and is offered in traditional and VOC compliant versions.

U92 Top Coat

U92 is an aliphatic top coat providing UV stability and reflectivity for the finished system. Offering superior puncture, chemical, and abrasion resistance, U92 delivers long-lasting durability, with low VOC compliance across all 50 states.

Why Choose A Urethane Roof System

The U9 series of products are single-component and VOC compliant in all 50 states.  This system can be used over metal, asphalt, and single-ply roofing systems and is the ideal coating solution for rejuvenating existing roofs that require high durability and impact resistance.  GacoFlex U90 mastic provides single pass reinforcement for seams and detail work eliminating the need for three-course application.  GacoFlex U91/U91C provides a weathertight seal that protects the substrate from degradation caused by UV, water, and other normal weathering hazards. Apply a top coat with GacoFlex U92 Aliphatic Urethane to add additional long-lasting reflectivity to your roof. 

GacoFlex U91/U92 may be brush-applied, rolled, or spray-applied and meet the requirements of Florida Maintenance coating specifications (Note: these are pending code compliances). Three coats are recommended for most roof coating applications with the finish coat being the U92 aliphatic. The coating surface can generally receive another coat within 10-12 hours, and may be walked on within 24 hours. 

The GacoFlex U9 system may also be combined with GacoRoofFoam for a total roof replacement solution.
