Ice dams are formed by the continuous melting and refreezing of snow on the roof. This is caused by heat escape, usually due to lack of insulation or the backing up of frozen slush from the eavestrough. Water from the melting snow flows under it until it reaches the unheated soffit area and refreezes. This causes a dam where it can easily push back up under the shingles and cause water to enter the attic causing damage to the interior walls, ceiling, insulation and of course the roof deck.
When it comes to choosing the right roofing contractor, there are many things you should consider before making the final decision. Your roof is protecting one of your most valuable assets (your home), so it’s important to make the right choice when it comes time to repair or replace.
