4 Signs Your Roof Isn't Properly Ventilated

 Ventilation plays an important role in the lifespan and durability of your roof. A typical asphalt roof should last 15-20 years and sometimes even longer depending on the quality of your shingles. If your roof isn't properly ventilated, damage can occur and decrease the lifespan of your roof. Not sure if your roof is properly ventilated? Read on to find our four signs your roof might not be properly ventilated. 

 

#1 Damp or Moldy Rafters and Ceiling Joists

One of the most noticeable signs 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. 

#2 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. 

#3 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.

#4 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.
