Roof Ventilation Problems and How to Prevent Them

With the improper ventilation or airflow, your attic can retain excess heat – leading to uneven melting of snow and costly ice dams.

Roof ventilation problems can mean more than just a stuff attic.

Thankfully, there are some measures you can take to prevent roof ventilation problems.

How to prevent roof ventilation problems

Your attic and roofing system do more than just keep the rain, wind, snow, and ice out of your home, they also work together to maintain proper ventilation and airflow. There’s a reason you see vents such as ridge vents, gable vents, and soffit vents in the roofing system. A good ventilation system will let the hot air rise and escape from the attic while letting cooler air circulate from the bottom, unlike some roofing ventilation problems you might experience.

Why is roof ventilation important in New England?

If the attic floor is poorly insulated, your attic can heat up quickly. If the attic and roofing system doesn’t allow for that hot air to escape and be replaced by cooler outside air, this can spell trouble in the winter. When your roof is covered with a snowpack, having a warm attic and roof can melt the snow underneath. This melting snow drips down your roofline and can refreeze at the gutter or roof edge, creating an ice dam.

Then when the melting continues, the water builds up with nowhere to go – and can back up through your shingles into your house, causing water damage. To avoid these destructive ice dams, it’s best to address your roof ventilation problems early on.

Make sure none of your belongings are blocking airflow

Attics are a common storage area for most homeowners but make yourself familiar with the venting system in your attic, and be sure your storage belongings are not blocking the natural airflow.

Inspect and replace any damaged insulation

Take a close look at the current insulation on the attic flow and look for damage or areas of replacement. For example, if a roof leak or ice dam wets fiberglass insulation, it can become matted down and compressed, reducing the insulation’s effectiveness. Other types of insulation become less effective as well, and all become susceptible to mold and mildew.

Ensuring proper insulation on your attic floor will not only save you on heating and cooling costs but also help the attic ventilation system regulate the temperature effectively. Consult a professional to determine the appropriate insulation level for your attic as well as how to remove and replace insulation materials safely. 

Have a professional assess your ventilation system.

Sometimes involving professionals is the best approach when evaluating the overall ventilation system. In addition to inspecting the insulation, they’ll look at vent placement and airflow.  

They may recommend insulation replacement, additional vents, or even attic fans to mechanically encourage airflow. It’s best to address these issues as part of your spring, summer, or fall maintenance to have all the work done before snow flies, if at all possible.
