Koolseal? That sounds interesting.
Well, in the interest of accuracy, Koolseal is not recommended for shingle roofs. I used it on an older asphalt shingle roof anyway. <img src="/images/graemlins/smirk.gif" alt="" /> I worked great for at least 5 years and several hurricanes. I lost NO tabs in Hurricane Georges, while houses around me lost a bunch. There are other elastomeric roof coatings that are listed for asphalt shingle
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 which 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.
