Problems Caused by Poor Attic Ventilation

Does your roof get ice damns in the winter?

Are the rooms on your second floor unbearably hot in the summer?

These problems all start with a lack of attic ventilation. And it’s not just a little ice or heat you have to worry about. Insufficient ventilation in your attic can create serious problems for homeowners.

Let’s take a look at warning signs of poor attic ventilation.

Poor Air Flow

Heat rises, and with a lack of ventilation, that heat gets trapped in your attic. In the summer, trapped heat can create unsuitable temperatures in your upstairs rooms, making it difficult to sleep in or use the rooms. On a 90° day, the temperature in your attic can reach 140° or more. Excessive heat puts your shingles at risk, leading to expensive repairs or replacement.

Ice Dams

Without proper ventilation, your attic won’t be evenly heated. In the winter, you’ll have warm air near the roof peak which can melt snow. As the melted snow travels downward to the eaves of the roof, it can refreeze against the cooler surface, which leads to ice damns. As water thaws, freezes, and expands it can damage your shingles and cause leaks.
