How Summer Heat Affects Your Roof (and What You Can Do About It)

Summer in Michigan is a welcome change—longer days, lake trips, BBQs, and warm weather. But while we’re soaking up the sunshine, your roof is taking a beating. At BC Exteriors, we want to help homeowners understand how intense summer heat can quietly damage your roof over time—and what you can do to prevent costly issues down the road.

 

The Michigan Summer Sun: A Silent Roof Killer?

Here’s what’s happening up there on a hot July day:

  • UV Rays break down shingles, even on cloudy days. Over time, this leads to cracking, curling, and loss of protective granules.
  • Thermal Expansion causes materials to expand during the day and contract at night. This movement can cause shingles and sealants to separate or loosen over time.
  • Poor Ventilation traps heat in your attic, which can “cook” your roof from underneath—and even damage insulation and raise your energy bills.
  • Humidity and Summer Storms create the perfect environment for mold, algae growth, and moisture damage if your roof isn’t properly sealed or ventilated.

It’s not just about looks. These conditions can lead to serious structural issues and a shortened roof lifespan if left unchecked.

What Can You Do About It?

You don’t need to climb on your roof to stay ahead of the game—just call in the pros (that’s us!).

Here’s what we recommend:

  1. Schedule a Mid-Summer Roof Inspection

Our experienced team can spot the early signs of heat damage, granule loss, and poor ventilation before they become expensive repairs.

  1. Check Your Attic Ventilation

Proper airflow in your attic is key. We make sure it’s doing its job—keeping your roof cool, extending its life, and reducing your energy bills.

  1. Clean & Inspect Gutters

Backed-up gutters can lead to water damage during those surprise summer storms. We’ll check for clogs and ensure your system is flowing properly.

  1. Consider a Reflective Roofing Material (if it’s time for a new roof)

We offer high-performance shingles designed to reflect heat and withstand intense summer conditions. And yes, they still look great.
