There is more to a roof than shingles and felt paper. Experienced roofers know that a quality roofing job actually starts in the attic. Proper ventilation is essential to the health of the roof and a great roofing company will inspect the attic and correct ventilation problems. Here are a few of the problems that can result from the attic not being ventilated properly.
Purpose of Ventilation
The attic is meant to move air across the bottom of the roof decking. Cooler air is pulled in along the walls of the house at the soffits and it helps move the hot air out of the attic through the top vents. This reduces heat, moisture and many other problems.
Mold, Mildew, Rust
When the attic is not ventilated, condensation can build up along the bottom of the roof deck. A professional roofing company will look for signs of mold and mildew in the attic, as those are indications of poor ventilation. Rust streaks around the nails are also another strong sign that the attic ventilation must be corrected.
Frost and Ice Dams
Frost can actually form in the attic from poor ventilation, and ice dams can quickly build up on the exterior of the roof. Water from a melting ice dam is liable to find its way through your roof deck and into the attic space. There, the water from ice dams or frost may cause problems with mildew or mold and work its way into your house. If you notice water stains on your ceiling, there is a good chance that your attic is not properly ventilated.
High Cooling Costs
The heat that builds in your attic will push down on your home, causing your air condition to work harder. The unnecessary strain on your air conditioner unit can cause it to fail sooner rather than later.
Shorter Roof Life
The constant moisture directly under the roof and excessive heat takes a toll on the roof decking. Plywood may start to rot and even the shingles’ integrity can be compromised. Roof repair in Oklahoma should always include correcting any ventilation problems so your roof will last as long as possible.
