Experienced Ice Dam Prevention
Ice dams are accumulations of ice that can form on the edge of your roof. Ice dams can also lead to major damage inside your home. Protect your most important investment from this risk with help from C V Insulation LLC.
Backed by years of experience, our technicians know how to install insulation that will minimize the potential of ice dams forming while also saving you money on energy costs.
How Ice Dams Are Born
It all starts when heat collects in your attic and warms the roof, except where the eaves are. The snow that is on the warm roof begins to melt, but then freezes when it meets the eaves. Ice accumulates along the eaves, forming a dam. Meltwater from the warm roof backs up behind the ice, flows under the shingles, and then into the house.
Invest in Adequate Attic Insulation
Better insulation in your attic is part of the solution for preventing ice dams. In Iowa, it is recommended that your attic insulation be at least 12 inches deep. It should be installed correctly, without any gaps between sections, and in conjunction with a vapor barrier. You can count on our skilled team to make sure that happens.
Make Sure Your Attic Has the Right Ventilation
Ventilation is the second part of an ice dam solution. Your attic should have adequate inlet and outlet vents. If these do not exist, look into installing a continuous soffit and ridge ventilation system. With this system, a vent is installed that runs the entire length of your roof's apex. Hot air rises up and out through this ridge vent.
The ridge vent helps creates a vacuum inside your attic when it sucks cold air in through the soffit vents, further cooling down the trouble zone at the eaves. It is a natural solution that does not require fans, wires, or anything else that might need maintenance.
