As a Michigan homeowner well versed in the varied weather patterns in this region, you may assume winter takes a greater toll on your roof. However, the truth is, summer can be just as demanding. Prolonged exposure to high temperatures, intense UV rays, and sudden storms can all shorten your roof’s lifespan. It can also result in costly roof repairs if ignored.
Here’s a look at how summer weather affects your roof and what you can do to protect your investment. Hiring a roofing contractor in Metro Detroit to periodically inspect your roof is a wise proactive move.
How Heat Affects Roofing Materials
Your roof absorbs a lot of heat during the summer. On sunny days, roof surface temperatures often hit well above the outdoor air temperature, causing roofing materials to expand throughout the day and contract again as temperatures cool overnight.
This constant cycle of expansion and contraction weakens your roof over time by:
- Causing shingles to become brittle over time
- Loosening roofing nails and fasteners
- Creating small gaps where moisture can enter
- Accelerating the aging of roofing materials
Over many years of repeated heat exposure, your roof’s performance can really take a hit.
The Impact of UV Rays
Sunlight doesn’t just generate heat; it also exposes your roof to ultraviolet (UV) radiation. These rays degrade the protective oils within asphalt shingles so that they dry out and become brittle.
You may start noticing:
- Curling or buckling edges
- Cracked or brittle shingles
- Granules collecting in your gutters
- Fading or discoloration
Summer Storms Can Make Existing Problems Worse
From strong thunderstorms and heavy rain to hail and high winds, summer storms can make existing problems on your roof much worse and possibly lead to major leaks.
After every storm, inspect your property for signs of damage such as:
- Missing or lifted shingles
- Fallen tree limbs
- Water stains on ceilings
- Damaged flashing around vents or chimneys
- Debris accumulating in gutters
Everything may seem OK from the ground, but there could still be hidden damage present. This is why regular, professional inspections are so important in pinpointing issues before they spiral into expensive repairs.
Don’t Forget About Roof Ventilation
Proper attic ventilation will help to protect your roof during the summer. Insufficient airflow traps heat in the attic, causing temperatures to climb even higher. Excessive attic heat can:
- Drive up energy bills
- Prematurely age roofing materials
- Place additional stress on attic insulation
- Cause moisture buildup due to fluctuating temperatures
A well-ventilated attic not only regulates temperatures, it supports the long-term health of your entire roofing system.
