Is Your Roof Properly Ventilated?

Did you know that proper ventilation on your roof at the Lake of the Ozarks can play a part in how long your roof last? A typical asphalt roof should last anywhere from 15 to 20 years but if you don't have proper ventilation, the life of your roof could go down considerably. In addition to the life of your roof, your roof ventilation can affect the performance of your heating and cooling system. Not sure if your roof is properly ventilated? Our roofing company at the Lake of the Ozarks has 4 signs that your roof isn't ventilated properly. 


1. Matted or Flattened Insulation

When excessive moisture starts to collect in your attic, it penetrates the insulation first. If you notice that your insulation looks clumped or flattened, it's likely from moisture. To inspect the situation further, put on a respirator, separate a few batts of insulation and look for mold inside. Mold tends to grow when it's warmer so this issue may become more noticeable in the spring and early summer.

2. Damp or Moldy Rafters and Ceiling Joists

One of the most noticeable signs that your home is improperly ventilated is the presence of condensation, mold, and mildew in the attic. Under cold weather conditions, the moisture in the warm air from inside your home will condense on the underside of the roof deck, leading to mold growth and the rapid deterioration of the wood decking under your roof. Inspect the rafters and ceiling joists for moisture and any signs of mold or mildew.

3. Rusty Metal Fasteners

Fasteners include screws, nails or bolts. When your attic is filled with excess moisture from improper ventilation, these fasteners can easily become rusted. When those get rusty and loose, you could experience shingle loss. The moisture caused by condensation inside your attic can also lead to rust on things like plumbing, heating and venting duct straps.

4. Ice Dams on Your Roof

During the winter months, improper ventilation can lead to ice dams on your roof. This is where snow melts on your roof and then freezes again at the edge of the roof or in the gutters, prevent the proper flow of water off the roof. The main cause of this roofing issue is an excessively warm attic.
