Quad Cities Roofing Pros

Quad Cities Best RoofingG.W44


Any good Quad Cities roofing company will tell you that all high quality roof replacements start with a tear-off. This is because it allows a visual inspection of the roof deck, and any problems associated with the deck, can be quad cities roofingcorrected before the application of the new roofing membrane. Underlayments and ice & water shield can also be installed to a clean roof deck. Although, removal of the old roof is a good starting point, there are several other components in a quality roofing system that work together to give you the protection and durability that you expect.

Attic Ventilation

Attic ventilation is often overlooked on new roof installations. The attic space is part of the roofing system, and certain conditions need to be maintained, which affect the durability, longevity, and warranties of today’s roofing products. The purpose of roof vents is to release moisture buildup and to keep your attic temperature as close to the outside temperature as possible.  Attic ventilation is an important element in the prevention of ice dams and water infiltration in the Wintertime.

Attic Insulationroofing quad cities

Most homeowners don’t relate insulation to a roofing system, but attic insulation is another important element in roofing systems in the colder parts of the country. As stated above, the roof vents are there to rid heat in the attic and keep the attic temperature near the same as the outside temperature. Adequate attic insulation will help prevent interior heat from leaking  into the attic space in the Wintertime.

Ice Dams

Ice damming occurs on many homes in the Quad Cities every Winter. In freezing temperatures, accumulated snow will begin to melt on a roof when the attic temperature is above freezing. The water from the snow melt will re-freeze at the overhangs, or eaves where there is no attic heat. This melt freeze process creates large ice formations along the eaves of a roof. The water on the backside of the ice dam can get several inches deep. The water can run back under shingles leading to interior leakage.

Ice & Water Shield

As a final preventative from water infiltration caused by ice dams, a waterproof underlayment, or ice & water roofingshield, should be applied to a clean roof deck along eaves and in valleys. The modified bitumen membrane is designed to seal around all roof fasteners that penetrate it.
