Signs Your Roof has Poor Ventilation

Your roof is the first line of defense for your home against the harsh elements of the Twin Cities Climate. Your roof protects the rest of your home from rain, hail, sleet, snow, wind, and countless other elements mother nature can dish out. When your roof has poor ventilation, the chances of ice dams forming in the winter will rise. Along with ice dams, the shingles on your roof will deteriorate much faster than roofs with proper ventilation. Lastly, moisture can build up much quicker in your attic with poor ventilation.

Let’s take a go over some signs of poor ventilation you should look out for!

Deteriorating Insulation

Insulation in your attic plays an important role in keeping a proper temperature in your home all throughout the year. In addition to a consistent temperature, insulation in your attic helps prevent ice dams during the winter.

When you have poor ventilation in your attic, your insulation will deteriorate at a rate much faster than proper ventilation. When warm air sits and stagnates in your attic, moisture from that air will be absorbed in the insulation which will lead to faster degradation.

Damp or moldy insulation is a sure sign of poor roof ventilation.

Moisture in Attic

As mentioned above, warm air will sit in an improperly ventilated attic. This trapped warm air will not only damage your insulation but will also damage other parts of your attic as well. Mold and mildew can form in warm, moist environments such as this which can cause deterioration of the framing of your roof.

If you inspect your attic and find spots of mold or mildew growth, your roof’s ventilation is severely lacking.

Damaged Shingles

The moisture in your attic not only affects parts of your attic, but it will also damage parts of your exterior as well. A warm attic is a perfect recipe for ice dams in the winter.

When an attic traps warm air inside, it keeps the overall temperature of your roof warm as well. During the cold months, snow can melt as a result of the warm temperature. The snow melts will trickle to the end of your roof and freeze. This process repeats until you have a full-fledged ice dam on your roof. Ice dams can cause tremendous amounts of damage to your shingles and can be a hazard for your family as well.

If you spot an ice dam forming on your roof, chances are you require proper roof ventilation!
