VS.
During its lifetime, your roof experiences thermal shock, or wide
variations in heat and cold. StormMaster® Slate shingles are built
to mitigate the eects of expansion and contraction due to
temperature changes.
ThermalCore™ Technology also leads to better granule adhesion.
Even as the shingles expand and contract, they are less prone to
shedding granules.
Granule adhesion is important because shingle granules play a
critical role in protecting your roof from the elements. Premature
granule loss can lead to accelerated aging, asphalt exposure, and
roof deterioration.
