Michigan summers might seem mild compared to winter—but don’t be fooled. Heat, humidity, UV rays, and severe storms can cause serious wear and tear on commercial roofing systems. Minor problems overlooked during summer can develop into significant, expensive issues by fall if not addressed.
Now is the perfect time to focus on roof maintenance in Michigan. Here’s how to protect your commercial roof during the hottest months of the year—and beyond.
1. Inspect for Heat and UV Damage
Flat and low-slope commercial roofs absorb a lot of sun. Over time, UV rays can dry out membranes, crack sealants, and weaken adhesives. This leads to premature aging and system failure if not addressed.
Look for:
- Blistering or bubbling
- Cracks along seams and edges
- Faded or brittle membrane surfaces
Schedule a professional inspection mid-summer to catch heat damage early—before it leads to leaks.
2. Check for Storm-Related Issues
Summer storms in Michigan often bring high winds, hail, and heavy rain. After every major weather event, it’s smart to visually inspect the roof or call for a quick check-up.
Pay close attention to:
- Debris buildup (especially near drains)
- Loose or lifted flashing
- Signs of impact from hail or flying branches
Quick action after a storm can prevent minor issues from becoming full replacements.
3. Keep Drainage Systems Flowing
Standing water is a major risk during the summer. Downpours can overwhelm drains or scuppers, especially on flat roofs. Make sure your drainage system is ready to handle sudden summer rain.
Routine maintenance should include:
- Leaf and debris removal
- Ensuring downspouts are clear and connected
- Checking for soft spots near drainage areas
Effective drainage is one of the most important aspects of roof maintenance in Michigan, no matter the season.
4. Inspect Rooftop Units and Penetrations
The summer heat puts added stress on rooftop HVAC units and other equipment. If the seals around them are cracked or shrinking, water can easily enter the building.
Inspect around:
- HVAC units
- Skylights and vents
- Pipe boots and cable penetrations
Look for cracked caulking or soft membrane areas. Tight seals around all units will help your roof resist both summer rains and the freeze-thaw cycles to come.
5. Prepare for What’s Next
While summer is the focus now, it’s also the ideal time to plan ahead. Addressing small repairs during warm, dry weather is safer and more cost-effective than waiting until fall or winter.
This includes:
- Scheduling inspections
- Repairing minor membrane damage
- Recoating or sealing if needed
Getting ahead of seasonal maintenance now will keep your commercial property protected year-round.
Keep Your Roof Ready, Season After Season
Don’t wait for cold weather to start thinking about your roof. The high heat, UV rays, and storms of summer can cause just as much damage if you’re not prepared. Regular inspections, proactive repairs, and clear drainage go a long way in protecting your building.
With a seasonal approach to roof maintenance in Michigan, your commercial roof will be ready for whatever the weather brings next.
