Ice Dam Repair & Prevention Solutions

Homes in this area of the country are exposed to frigid temperatures and snow every winter.  Because of this, ice dams are a common issues that homeowners deal with.  Ice dams are caused when heat inside your attic warms the underside of the roof and causes ice and snow to melt. Ice dams can cause serious damage to your roof and can leak into your attic. When we talk about ice dams, one of the most frequent questions we get asked are" how do I prevent or repair ice dams?".  Preventing ice dams is fairly simple with the use of proper insulation and air sealing.

We are planning to do insulation for our basement and attic.
Vicinity of Carriage Drive in Bethany
We are primarily concerned with getting more heat in the finished room over the garage that is always cold (or hot). We probably need someone to inspect the adequacy of the heat duct/return to the room (which does nothing) and also check heat going to other living areas and improving the insulation. The garage is finished.
