Protect and Maintain Your Roof During Extreme Summer Heat

Extreme summer heat can be surprisingly hard on roofing systems, especially in Kalamazoo and Southwest Michigan where you get big temperature swings between seasons that can cause issues requiring roof replacement. The main issues that your roof faces in the summer are UV degradation, thermal expansion/contraction, and trapped attic heat that can “cook” shingles from underneath.

Booko Brothers offers some practical things you can do to protect and maintain your roof during hot weather:

Increase Attic Ventilation

When attic temps spike, shingles age faster due to heat trapped from below. Adding ridge vents, soffit vents, and powered attic fans (when properly balanced) can help push hot air out and pull cooler air in. A poorly ventilated attic can shorten roof life significantly, even if the shingles look fine from the outside. You should also make sure attic insulation is balanced with ventilation. This is a common mismatch, as too much insulation without airflow can trap heat instead of managing it.

Keep Gutters and Roof Edges Clear

Built-up debris in your gutters doesn’t just affect your roof when it rains; it can also trap heat and moisture along the edges of your roof system. This can accelerate shingle curling and wood deterioration at the eaves.

Trim Overhanging Branches

This is a catch-22, as shade is helpful in keeping your home comfortable, but heavy coverage can trap heat and moisture against the roof surface, which can facilitate algae growth, over time. Shingles can also become damaged when wind causes branches to rub against shingles that have been softened by long-term heat exposure.

Inspect Shingles for Early Heat Damage

When the heat soars into the 80s, 90s, or above, take the time to inspect your shingles and look for signs of curled edges or blistering, and check your gutters for areas when granules from the shingles are collecting. These are all telltale signs that your roof surface is drying out and aging faster than usual.

Check Flashing and Sealants

Any sealants around vents, chimneys, skylights, or other roofing features can soften or dry out with exposure to extreme heat. This can result in minor gaps that will can become leaks that allow water to enter your home when it rains.

Consider Reflective or “Cool Roof” Upgrades if Replacement Required

Lighter-colored shingles or reflective coatings reduce heat absorption and can noticeably lower the temperature of your attic.

Visually Inspect for Signs of Thermal Stress

After any extended heat wave, you should do a quick visual inspection of your roof for curled, cracked, blistered, faded, or loose shingles, as these can be signs of potential leaks or structural issues.
