Somay Roof Mastic®

SOMAY ROOF MASTIC® is a premium quality formulation, incorporating heavy duty acrylic resin emulsions which give it incredible resistance to degradation from exposure to the elements, and thus exceptional durability even in hot, tropical climates, the most severe environmental conditions for coatings to endure.

SOMAY ROOF MASTIC® is resistant to wind, rain, sunlight, ultraviolet solar rays, salt air, snow, sleet, hail, etc. First formulated in 1966, it has been tested and proven in use for years in various climates around the world, from Maine to California, from Canada to the Caribbean, from the deserts of the Middle East and Southwestern United States, to South Pacific tropical islands.

SOMAY ROOF MASTIC® will seal, waterproof and protect practically any smooth, structurally sound, well-drained roof surface when applied at the proper thickness according to instructions. TWO VERY THICK COATS of liquid SOMAY ROOF MASTIC must be applied so that they dry and cure to a virtually impenetrable, flexible, seamless, waterproofing, protective membrane. SOMAY ROOF MASTIC® will adhere to properly prepared roof surfaces without cracking, peeling, chipping or flaking due to climatic exposure.

SOMAY ROOF MASTIC can provide HURRICANE PROTECTION for your roof. It is the ONLY ROOF COATING which stood up to the 175 m.p.h. winds of HURRICANE ANDREW on August 24, 1992. During Hurricane Andrew, roofs protected with the SOMAY ROOF MASTIC System stayed on, even in the middle of Homestead, Florida, in south Dade county, which received the most severe winds, while other roofs that were NOT protected with SOMAY ROOF MASTIC were peeling off and flying away, leaving houses exposed to the sky, the wind and the rain. ONLY SOMAY ROOF MASTIC has a proven record of providing superior HURRICANE PROTECTION for your roof!

SOMAY ROOF MASTIC is an excellent SOLAR HEAT INSULATOR. Based on independent research by the Thermophysical Properties Division of Battelle's Columbus Laboratories, SOMAY ROOF MASTIC has a thermal conductivity rating similar to that of wood or insulating firebrick, and 1/100 that of steel, and 1/1000 that of aluminum! Conclusion: SOMAY ROOF MASTIC is "considered a very good thermal insulator" ... i.e., it is a very poor conductor of heat.

SOMAY ROOF MASTIC is an excellent SOLAR HEAT REFLECTOR ."White" SOMAY ROOF MASTIC has a solar reflectance value of 83%, which is exceptionally high for a coating, leading to the conclusion that SOMAY ROOF MASTIC is "superior in relation to all common building materials in the rejection of radiated heat" ... i.e., it is a very poor absorber of heat.

Thus, SOMAY ROOF MASTIC is unique among building materials in that it is BOTH a very good THERMAL INSULATOR (Non-Conductor of Heat) and a superior THERMAL REFLECTOR (Non-Absorber of Heat).

Because of these unique properties, SOMAY ROOF MASTIC can very significantly reduce AIR CONDITIONING ENERGY CONSUMPTION. This was confirmed by additional independent research conducted by The Florida Solar Energy Center (Part of The State University System of Florida), as shown in Report No. FSEC-P-F-274-94. Results after SOMAY ROOF MASTIC was applied to a variety of roof surfaces, including asphalt shingles, bitumen, tile roofs, etc. showed that the SOMAY ROOF MASTIC:

1. Increased roof reflectivity over 234%
   (from .22 to .73).
2. Reduced roof top surface temperatures over 35%
   (from 170° F. to 110° F. = 60° F. reduction).
3. Reduced under roof (attic) temperatures over 31%
   (from 134° F. to 93° F., = 41° F. reduction equal to practically ambient temperature)
4. Reduced Air Conditioning Energy Consumption over 43%
   (from 1478 W. to 838 W.). , and "savings would have been higher had the house had an air conditioner capable of meeting the cooling demands prior to the application of ROOF MASTIC. After the ROOF MASTIC application, the air conditioner CAN keep the house interior cool!"

SOMAY ROOF MASTIC breathes to allow water vapor to escape and structures to breathe.

SOMAY ROOF MASTIC has exceptional flexibility and elongation to accommodate the normal expansion and contraction of roof surfaces.

SOMAY ROOF MASTIC has exceptional durability and long service life.  Weatherometer tests have shown that SOMAY ROOF MASTIC shows NO degradation even after 15 years of ultraviolet light exposure.  Actual roof applications, even in the very severe climate and ultraviolet sunlight exposure of South Florida, have shown that many applications are continuing to serve satisfactorily after more than 25  or 30 years.  So that why we say it can allow your roof to last indefinitely!

SOMAY ROOF MASTIC is FIRE-RESISTANT and will not support combustion.

SOMAY ROOF MASTIC is both USER and ENVIRONMENTALLY FRIENDLY. It complies with all known current federal, state and local Volatile Organic Compounds (VOC) regulations ... it has NO unpleasant odors (so much safer and nicer to have around and work with than hot, smelly tar kettles) ... it eliminates the expense, bother, noise, dust, dirt and mess of tearing off old roofs, which then require being hauled to landfills or dumps. ROOF MASTIC will never have to be taken off to be disposed of, because SOMAY ROOF MASTIC can last indefinitely - and you can clean up yourself and your application equipment with just soap and water.
