When the Michigan summer heat hits full force, you’re probably focused on staying cool inside your home. But what if your roof is working against you? At BC Exteriors, we’ve seen it time and time again—homes struggling with excessive indoor heat and high energy bills simply because of poor roof ventilation.
Let’s talk about why proper ventilation is a key player in keeping your home comfortable during hot weather—and what can happen if it’s not doing its job.
Why Roof Ventilation Matters in Summer
Your attic acts like a heat trap. When sunlight hits your roof, the shingles absorb the heat and transfer it into the attic space. Without proper airflow to carry that heat away, your attic can soar to 150°F or more on a hot day.
That trapped heat doesn’t just stay put—it seeps into your living spaces, making your air conditioner work overtime. The result? Higher cooling costs, reduced HVAC lifespan, and a whole lot of discomfort.
The Right Ventilation Creates a Cooler Home
A well-ventilated roof system uses a combination of intake and exhaust vents to keep air flowing through your attic. This steady movement of air helps:
- Expel hot, stagnant air from the attic
- Reduce moisture buildup, which can lead to mold or rot
- Improve energy efficiency by easing the load on your cooling system
- Extend the life of your roof, shingles, and insulation
When ventilation is balanced, your attic stays closer to the outside temperature instead of turning into a sauna.
Warning Signs of Poor Ventilation
Think your ventilation might not be up to par? Here are some red flags to watch for:
- Your upstairs rooms feel significantly hotter than downstairs
- You notice higher-than-usual electric bills during the summer
- Your attic feels stifling or smells musty
- Your roof shingles are curling or deteriorating prematurely
If any of these sound familiar, it might be time for a ventilation inspection.
At BC Exteriors, we believe in doing it right the first time. When we inspect a roof, we’re not just looking at the shingles—we check the entire system, including intake and exhaust ventilation. Whether it’s upgrading soffit vents, installing ridge vents, or rebalancing airflow, we’ll make sure your roof helps your home beat the summer heat—not trap it.
