Can Your Roof Take the Heat? Why Summer Maintenance Is Critical for Commercial Roofs.

Summer in the Midwest is a season we look forward to for obvious reasons. Sunshine, longer days and the energy that comes with finally shaking off the cold are welcomed with open arms by all… except maybe your roof.

While the warmer weather brings plenty of perks, it also brings challenges that can quietly wreak havoc on your commercial roof. And if you don’t prepare now, the hot months ahead could reveal vulnerabilities that lead to permanent damage or even unexpected system failure.

But summer roof maintenance isn’t a job for your internal maintenance crew. Identifying hidden issues and preparing your roof for what’s ahead takes trained eyes and specialized expertise. That’s where a trusted commercial roofing partner comes in.

In this article, we’ll break down the summer-specific challenges commercial roofs face and how a roofing expert will keep your system performing under pressure so you don’t have to.

What Risks Does Summer Pose to a Commercial Roof?

Winter might get all the attention, but summer can be just as brutal on your commercial roof — especially here in the Midwest. When temperatures spike, roofing systems expand. When the sun beats down day after day, UV exposure starts to degrade materials. And when those surprise summer storms roll in, they often bring high winds, heavy rain and flying debris that put your roof to the test.

Unlike cold-weather damage, the toll of summer heat often goes unnoticed until it becomes a costly problem. Just because your roof survived the winter doesn’t mean it’s in the clear. In fact, summer is when some of the most preventable (and expensive) roofing issues tend to appear.

By staying proactive with seasonal maintenance, you can:

• Prevent material breakdown caused by UV exposure and extreme temperatures
• Catch and correct storm-related damage before it impacts the interior
• Ensure rooftop equipment isn’t compromising the roof’s integrity
• Avoid emergency repairs that disrupt your operations
• Keep your building compliant with warranty requirements

Not sure what summer roof maintenance should actually include? Here’s what a reliable roofing partner will do to keep your system in top shape through the heat and storms ahead.

How Can a Trusted Roofing Partner Protect Your Roof This Summer?

When temperatures rise, so do the risks to your roofing system — and the best way to stay ahead is with a detailed summer maintenance plan. A qualified commercial roofing partner like Superior Services will know what to look for and how to take action before small issues become expensive emergencies.

Here are the key steps they should be taking this season:

1. Inspect for UV and Heat Damage

Prolonged exposure to sun and heat can silently break down your roofing materials. A professional will inspect the entire surface for signs of UV degradation, including:

• Faded or brittle membrane materials
• Cracks, blisters or warping that indicate trapped moisture or thermal stress
• Splits along seams or flashing, where expansion and contraction are most likely to cause failure

Flat roofs are especially vulnerable to these kinds of issues because the surface area absorbs and retains heat throughout the day. Beyond spotting surface-level signs, a reliable commercial roofing partner will also assess how heat stress might be impacting the roof’s overall integrity and whether any repairs or reinforcements are needed to prevent failure.

2. Examine Rooftop Equipment and Penetrations

Summer means HVAC systems are working overtime, and those units can be a weak spot if not properly sealed. Your roofing team should closely inspect areas around:

• HVAC curbs and support structures
• Pipes, vents and conduits
• Electrical boxes or other rooftop equipment

They’ll check for loose seals, membrane wear from vibration or water infiltration around penetrations — all common failure points when temperatures rise and systems shift. They should also confirm that service walk pads, if present, are still intact and protecting the membrane from technician foot traffic.

3. Assess Drainage After Heavy Rain

Sudden downpours are common in summer, and if your drainage system isn’t working properly, standing water can become a serious threat. Your roofing contractor should:

• Clear debris from drains, scuppers and gutters
• Check for signs of ponding, especially in areas that saw snow load or damage earlier in the year
• Inspect for algae or plant growth, which indicates long-term moisture retention

Proper drainage is your first defense against summer storm damage. A good roofing partner will not only clear obstructions but also identify areas that need slope corrections or structural attention to prevent future problems.

4. Check for Signs of Material Movement or Separation

As your roof heats up during the day and cools off at night, the constant expansion and contraction can slowly pull at seams, flashing, fasteners and termination points. Over time, this movement can lead to serious vulnerabilities — especially if your roof has already weathered years of seasonal change.

Your roofing partner should thoroughly inspect:

• Membrane seams for gaps, lifting edges or failed adhesives
• Flashing details where different materials meet or where movement is common (like parapet walls or rooftop units)
• Termination bars, fasteners and perimeter edges to ensure everything remains sealed and secure

These small separations may not seem urgent, but even minor gaps can allow water to enter and cause damage to the insulation, decking or interior. A qualified contractor will address these issues before they lead to larger repairs.

5. Review Interior Spaces for Signs of Water Infiltration

Sometimes the biggest roofing problems are discovered from the inside. Your contractor should go beyond the surface and inspect interior areas that may reveal hidden leaks or trapped moisture. That includes:

• Ceiling tiles, walls and insulation for staining, bubbling paint or sagging
• Mechanical rooms or attics where condensation, rust or musty smells may indicate long-term moisture intrusion
• Areas beneath rooftop units or penetrations that are especially prone to slow-forming leaks

Because HVAC systems and rooftop penetrations are working harder in summer, small leaks can worsen quickly and spread undetected. A good roofing partner will use visual inspection (and in some cases, moisture meters or infrared technology) to catch early signs before they become costly issues.

6. Create or Update Your Preventive Maintenance Plan

Summer is the perfect time to step back and evaluate your long-term maintenance strategy. Whether you already have a plan in place or are starting from scratch, your contractor should help tailor a program that fits your roof’s material, age, size and usage.

A preventive maintenance plan should include:

• Scheduled inspections in summer and other critical seasons
• Clear documentation of all maintenance and repairs for warranty and insurance purposes
• Budget-friendly planning for any anticipated capital repairs or replacements

No matter your roof type, a proactive maintenance plan is your best bet to get the most life out of your existing roofing system.
