Your Roof Repair Checklist: 5 Signs Of Poor Attic Ventilation And How To Fix Them

Is your attic's insulation covered in mold? Do you have to fight off ice damming frequently? If you answered yes to either of these questions, then you might be dealing with poor attic ventilation. Here are different signs of poor attic ventilation and roof repair solutions to fix them:

1. Moldy Odor

Do you sense a musty smell when you climb into the attic? It's likely that there is a buildup of moisture due to poor ventilation. A quick fix to this problem is by installing a vent fan or exhaust fan. This will help remove any excess moisture from the air, preventing mold growth.

2. Condensation on Ceilings

If you notice any condensation on your ceilings, it's a sign that your attic isn't ventilated properly. It shows the moisture level is very high or has been going for a long time to cause stains on the ceiling. 

If you can see stains on the bottom side, the inner is usually extensively infested by mold. To fix the problem, you'll need a roofing contractor to assess whether you need a roof replacement.

3. S-Curves in interior walls

If you notice S-shaped curves in your interior walls, this is a sign that your attic isn't properly ventilated. These curves are caused by the warm air in your attic rising and causing the snow on your roof to melt. 

This water can then refreeze, causing the S-curves. Roof repairs for this problem involve adding more ventilation to your attic. This can be done by adding more vents or by installing a ridge vent.

4. Ice Damming

This occurs when heat escapes from your home through the roof, melting the snow on your roof. The water then refreezes, forming a dam that prevents melted snow from draining off your roof. This can cause serious damage to your roof and home. To prevent ice damming, make sure your attic is properly ventilated. 

5. Moisture Stains on the Upper Sections of Interior Walls

If you see moisture stains on the upper sections of your interior walls, it's a sign that your attic isn't ventilating properly. The streaking is caused by water flowing down from the attic. To fix the problem, you'll need to add more vents or install a powered attic fan.

High levels of moisture in the attic can cause a myriad of problems, including persistent respiratory allergies. Therefore, you need regular inspections to identify and remedy emerging problems early enough. Call a roofer to schedule an inspection and determine the kind of roof repairs you need.
