What does roof vent maintenance entail? It’s all about when and why

We all know that proper ventilation, and keeping air circulating, is important throughout a home. But what about on top of a home?

Those roof vents you may not notice the rest of the year are especially important in the winter months, when snow or ice may be making an appearance. So if you have questions, MTB Mechanical would like to share some tips regarding the “when and why” of roof vent maintenance. 

First of all, what do roof vents do?

Your roof vents act as the gateway between your attic space and the outdoors, and help ensure that moisture doesn’t build up. Vents come in a variety of shapes and sizes, but all help your home “breathe” correctly. 

Should I cover my roof vents during the winter months?

Short answer: NO.

Why should I leave my roof vents uncovered?

It may be natural to think that covering your vents will help to prevent heat loss during the colder months. But keep in mind that most attics are insulated, and the heat from the rest of your home isn’t able to enter the attic easily. The cool air from outside should not affect your indoor air and energy consumption.

What happens if I cover my roof vents?

Without air circulating, your attic space could get warm and wet, and the excessive moisture may lead to potentially dangerous and costly conditions. This is why it’s essential to keep your roof vents open. The ventilation will keep the temperature regulated for the season and help prevent moisture from building up underneath your shingles.

When should I do maintenance on my roof vents?

Preparing your home for winter means thinking ahead. During the cooler seasons of spring and fall, when the temperatures aren’t blazing hot in your attic or on your roof, is a good time to inspect your roof vents. 

What does roof vent maintenance entail?

The most critical thing to look for is debris, and removing leaves, cobwebs and other obstructions from your:

  • Attic fan
  • Exhaust vents
  • Eaves

If all of these pathways are clear, air can flow freely from your attic, and the ventilation will function as it should in your home — from top to bottom, during every season.
