The dangers of roof icing
Most roofs can endure a heavy snowfall without damage, but ice can be more problematic. Jerry Hughes, a roofing contractor in Denver says ice damage has a very simple root cause: “The cause is a warm roof and cold soffit area."
Ice does damage as it expands in the roofing, either under shingles allowing a gap to form, or in an advanced case, actually pushing the wooden structure apart. This allows water into the structure of the roof where it obviously should not be. This expansion damage can be caused without a heavy storm; a pattern of temperatures dropping below freezing and returning above freezing coupled with precipitation is enough to do damage.
Gutters, loose shingles, flashing and of course trees and limbs that hang over your home all pose a potential danger to your roof and are more problematic when ice is involved.

Even in areas not associated with heavy winter storms, homeowners need to be aware of ice damage on roofing. Magnum Roofing's Piper Chilson, Dallas roofing contractor, warns that there is likely little chance of seeing damage to your roof from the ground, he says, "But if you can see damage from the ground, things have gotten extremely bad...You need a professional to determine just how bad the damage is.”
In addition to avoiding a roofing disaster in the middle of winter, another benefit to not waiting until ice has caused visible damage is that catching this kind of ice damage early can help you avoid bigger, more expensive issues down the line.
Chilson remarked that shingle prices are based on supply and demand, meaning that storms on the other side of the country could put you into a situation where you’ll be paying more based upon events far outside your region. A roofing contractor in Denver is going to pay as much for shingles as a roofing contractor in Dallas will, regardless of the fact that Denver might have more severe winter storms.
Catching a problem early may mean that you can choose when to do major roof repairs as opposed to when you’re forced to act quickly. When choosing a roofing contractor in your city, check out the member reviewed and top rated service professionals found on Angie's List.
