Long Island winters are notoriously cold, which means we want to turn up the heat. As we all know, heat rises and prompts the question, is there mold in your attic?

If there happens to be an attic in your house, that’s where it will rise to. If you have inadequate insulation you may end up with a mold problem.

The space above our living area isn’t thought of as much as we think of our kitchen or other frequently used areas. However, it is part of our indoor living environment.

Proper air flow is required to deal with the warmth that flows up. The roof gets cold and when that flow has no where to go, we end up with condensation. Just like that ice cold can of pop in the summer, except this time the moisture build up is on the inside

The longer the surface of the sheathing stays wet, the higher the chance for mold to grow. It can become accelerated based on how high the thermostat is set

While I am not a roofer by trade, I’m aware of a a few ways to get your space a little breathing room.

A soffit vent is simply a vent installed into the underside of your home’s eaves (called the soffit) that permits fresh outside air to be drawn up into the attic.

Another example is one at the top or ridge of your roof https://youtu.be/lOgYudKD-S4 here is a video example of an installation

Some homeowners may even install an exhaust fan which can pull air out with the flip of a switch or sensor.

Between December 2020 and January 2021 I inspected several attics in both commercial and residential settings and they all shared the same common trait of improper ventilation.

If you have not inspected yours in a while then you owe it to yourself to take a peek and see what’s going on, for if there is a problem you want to catch it before it gets out of hand as an attic mold remediation job can cost several thousand dollars.
