It is not always easy to decide between cool roof coatings, because there are several factors to consider when weighing their performance. The right coating for your roof will depend on the quality of the substrate, local weather conditions, and several other factors. Both TRC 7000 Perma-Coat Roofing and Elastek 127 Solar One Plus have a lot to offer consumers. So, which one is right for your roof?
Elastek 127 comes out well above TRC 7000 in terms of elasticity or elongation, so it may be the right choice for climates with extreme weather fluctuations, since changes in temperature are what will cause the roof coating to expand and contract.
Alternatively, TRC 7000 outranks Elastek 127 in tensile strength. Both have good adhesion to good substrate, but TRC 7000 can adhere much better than Elastek to poor substrate.
Elastek performed better on the scrub test, showing that it does maintain high durability. However, TRC 7000 is the winner for dirt retention, reflectivity, and bleed through.
Overall, these products both rank very closely, so the ultimate decision may lie with the quality of the substrate and the local weather conditions.
