As we had mentioned before, the LO/MIT-I reduced the surface temperature of the goodyear black rubber roof by 50+ degrees. While applying the LO/MIT-I product, we checked the surface temperature with an infrared non contact thermometer, and saw average readings on the untreated areas of 135 to 138 degrees. The areas we had already applied the LO/MIT-I were reading from 83 to 87 degrees.
