Thornton Roofing: Article About Protecting A Home From Ice Dams
Cold, snowy winters can wreak havoc with even the best roof. Fortunately, Thornton roofing contractors have some excellent advice on how homeowners can protect their roofs and how they can avoid the high cost of spring roof repairs.
When snow and cold weather combine, roofs that are not properly protected can develop ice dams. These ice dams are simply ridges of ice that form in the valleys of a roof or along the roof's eaves and gutters. Icicles hanging from roof edges might be a common sight during winter months, but it's important to realize why these icicles and ice dams form. The fact is, these ice formations occur because the underside of the roof is getting too warm.
Some people might think that there is no harm in having ice on their roof. After all, come spring, that ice is going to melt, along with any snow that is still standing on the roof. While this is true, the longer those ice dams remain on the roof, the greater the possibility that water will leak under the roofing shingles and find its way through the underlayment and onto the roof decking. This is a catastrophe waiting to happen.

Once water reaches the roof deck, the deck becomes saturated, can start to rot and will eventually lead to water leaks that cause damage inside the home.
Preventing ice dams does not have to be difficult. A roofing contractor can inspect a homeowner's attic and look for potential problems. There are a few major factors that can lead to a roof being too warm. One of these factors includes warm air entering the attic from gaps around vents, light fixtures and other elements that open into the attic. Sealing these gaps can keep warm air in the home and leave the attic cool. Other factors include poor air circulation and not having the right insulation, or R value, for the climate.
Insulation should be checked to make sure it is sufficient to prevent heat transfer to the roof. When the underside of the roof becomes warm, snow on the outside will start to melt. This dripping water leads to ice dams and, eventually, roof leaks. If the problem is poor air circulation, experienced roofing contractors can increase ventilation with the installation of attic fans as well as vents in the eaves or soffits.
Protecting a roof requires making sure the attic remains cool throughout the winter. With a few minor steps, roofing contractors can ensure homeowners have the right environment to keep their roof cool and prevent the damage that can occur when ice dams form.
