Ice damming is one of the most common causes of homeowner insurance claims in the winter, and usually happens when snow and ice melt upon contact with the heat radiating from a poorly ventilated roof. The resulting water trickles down into the unheated eavestroughs, where it pools and eventually refreezes to form frozen build-ups of ice.
As snow and ice continue to melt, these ice dams may then cause additional pileups of water to seep back into the roof underneath the shingles. After infiltrating a home’s attic, the water may even trickle down into the ceilings of the home, all while causing mould, mildew, fungus and structural rot to develop.
Aside from causing expensive repair bills, mould, mildew and fungus growth can significantly harm the indoor air quality of your home, leading to further health problems for you and your family.
Professionals in the mould removal industry have found that improperly ventilated attics can hold up to half of all the mould that is typically found in homes. If allowed to accumulate unchecked, mould can even lead to an entire home being condemned by local authorities in extreme cases.
It’s not just owners of older homes who have to be wary of these problems. Newer homes are especially at risk since the types of insulation used in newer homes usually absorb and retain much more moisture.

The lineup of solar-powered attic fans offered by iSolar Solutions provide the perfect answer to preventing these problems before they develop. These attic fans work by channeling warm air outside and away from the areas where snow and ice normally accumulate. This keeps your attic cool during the winter months, preventing problematic ice dams from forming in the first place.
Home heating bills already make the winter months quite expensive for homeowners. Designed with efficiency in mind, solar powered units are used to improve home comfort with no increase to the electricity bill. Most iSolar models have an automatic temperature shut-off option which will stop the fan once an attic has achieved a significant temperature reduction.
For added protection against the elements, iSolar’s flagship 19W-MOD-SNV Solar Attic Fan can be paired with the SNOWVENTCO Roofers Vent Cover in a package deal. Together, these products keep your roof cool during the winter months, and protect your roof from strong winds that may blow snow, hail and other moisture-inducing contaminants into your attic through the roof vents. All of iSolar’s products are built to last, and come with a 20-year limited manufacturer’s warranty.
