Verona Roofing: Article About Protect Roofs By Preventing Ice Dams
Anyone who lives in an area that gets heavy snowfall and freezing temperatures is probably familiar with the ridges of ice that commonly form on rooftops. While finding ice dams on roofs during the cold months of winter might be common, they are certainly nothing to ignore. These ice dams not only pose a threat of significant damage to the roof, decking, interior walls, ceilings and floors, but they are also an indication that there is a problem with the roof.
Understanding how and why ice dams form can help homeowners take preventative measures to ensure their home is protected. In cold, snowy climates, it is important to make sure that the underside of the roof remains cool. This is accomplished by providing sufficient ventilation in the attic or space under the roof. Additionally, the proper level of insulation in the attic as well as sealing leaks from the home can help keep the underside of the roof cool. A Verona roofing contractor can evaluate a home and make the corrections needed in order to protect the roof.
When the underside of a roof is warmer than the exterior, standing snow can start to melt. Unfortunately, the snow doesn't melt evenly. Typically, when attic ventilation or insulation are insufficient, the roof ridge or peak will get the warmest.

This causes snow to melt at these higher areas, but as the melting snow runs down the roof, there is no place for it to go. It hits the areas along the eaves where the roof is still below freezing and standing snow has not yet started to melt. As it hits this colder section of the roof, the draining water refreezes and ridges of ice begin to form.
Ice ridges should be removed as soon as they are noted. As melting snow begins to back up behind a block of ice, the water will find its way up under roofing materials and eventually to the roof decking. Once this happens, the decking becomes saturated, begins to rot and water may continue to spread to the inside of the attic and eventually into the home.
The time to take steps to protect a roof from this type of damage is before the first winter snowfall. However, if a homeowner discovers that there are ice dams forming on their roof, temporary measures can be taken. For example, commercial heat tape can be installed by a roofing contractor to help allow dripping water to drain off the roof.
