Cool Roof Testing (ASTM E-903; ASTM E-408)
To qualify as a cool roof system a roofing material must demonstrate
at least an Albedo (total solar reflectance) of 50 percent and maintain
at least an emissivity of at least 90 %. If either of these levels are
not maintained the system is not truly a cool roof system. The newest
testing standard qualifying for a cool roof system is the Hemispherical
Spectral Reflectance (ASTM E-903) and Emittance Test (ASTM E-408)
The test report concludes that Hydro-Stop’s PremiumCoat system has one of the highest “cool roof” ratings available in the industry. PremiumCoat white FinishCoat achieved a rating of better than 78% Spectral Reflectance while maintaining an emittance of greater than 94%.
Factory Mutual (Class 4470) Testing for Class 1 Roof Assembly
Hydro-Stop is very proud to be listed by Factory Mutual as a class one
roof system over a variety of substrates including concrete, steel, and
insulation board. Hydro-Stop is the only manufacturer of fluid applied
systems to have a class A-4470 roof recover as a stand alone roof system
over insulation board. To achieve this designation the PremiumCoat system
is subjected to strenuous testing for fire, wind uplift resistance, hail
damage, water leakage, and resistance to foot traffic. Having a FM approval
also requires periodic plant audits to insure the product formulation
and quality has not been altered or changed.
NSF National Sanitation Foundation Certification for Potable Water

of NSF/ANSI Standard 61 – Drinking Water system components.
