Three Other Benefits
One: When we
super-heat our attic it also super-heats our roof tiles which causes excess
wear because of the cooling (shrinking) and heating (swelling). If we heat our roof tiles up hotter than they
are rated, the shrinking and swelling over time will cause damage to the roof asphalt shingles. Let’s not even talk about the tar
paper that can be underneath. I know
that may sound a little over-exaggerated, but it really has that effect.
Keeping an even temperature in the attic may very well extend the life of your
Two: As the attic is
adjacent to the rooms below, a hot attic will prevent those rooms from cooling
off naturally. This creates a higher
demand on your air conditioning unit. So, reducing the temperature in the attic
improves your energy efficiency by a reduction in air conditioning energy
consumption. It also increases the life of your AC unit.
Three: Air movement in the attic also helps prevent moisture
from building up on the bottom of roofing materials and the rafters in the
summer. In the winter, the attic is cooler but still needs movement to prevent
ice dams from forming on the roof. If you turn off the solar powered roof vent in the winter, make sure your vents are operating properly so air can still
travel through the space.
