When most homeowners think about replacing a roof, the focus usually lands on shingles, underlayment, or warranties. But there is one critical component that often gets overlooked. Proper roof ventilation. In Michigan, where weather extremes swing from subzero winters to humid summer heat, ventilation can be the difference between a roof that lasts decades and one that fails prematurely.
In this guide, we will break down what ventilation does, why it matters for Michigan homes, the most common ventilation types, and how Roofing Army ensures your roof is set up for long term performance. By the time you are done reading, you will see ventilation not as an extra but as a core part of your roof’s defense system.
Your roof’s job is more than just keeping out rain and snow. A well designed roof system also allows air to flow through your attic space, keeping temperatures balanced and moisture under control.
Without proper ventilation, your home can experience:
In Michigan, where temperatures can jump from freezing to humid in just a week, ventilation is your roof’s year round pressure relief valve.
A balanced ventilation system includes both intake vents (usually at the soffits) and exhaust vents (at or near the ridge). Intake vents pull in cooler air from outside, while exhaust vents push warm, moist air out. This constant airflow keeps your attic closer to outdoor temperatures, reducing stress on your shingles and structure.
The key is balance. Too much exhaust without intake, or too much intake without exhaust, makes the system inefficient. That is why proper design and installation matter.
Ridge Vents
Installed along the peak of your roof, ridge vents allow hot air to escape naturally. When paired with soffit vents, they are one of the most efficient systems available.
Box Vents
Individual static vents placed near the roof’s peak. They are less continuous than ridge vents but still effective when spaced properly.
Soffit Vents
Located under the eaves, soffit vents bring fresh air into the attic and are crucial for balance. Without them, exhaust vents cannot work as intended.
Gable Vents
Installed in the gable ends of a roof, these can supplement other ventilation types but are not as effective alone in complex roof designs.
Skipping ventilation or installing it incorrectly can cause serious and expensive issues.
We have seen Michigan roofs fail years ahead of schedule simply because ventilation was not addressed during installation.
At Roofing Army, ventilation is never an afterthought. Every roof replacement we do includes a ventilation assessment as part of our Recon Report. We measure your attic space, check existing vent locations, and calculate exactly how much intake and exhaust is needed to meet manufacturer specifications and building codes.
Our approach ensures:
A great shingle without proper ventilation is like a sports car with no oil. It might look great, but it will not last. By ensuring your roof has balanced, efficient ventilation, you are protecting your shingles, your home, and your wallet from unnecessary repairs.
