As winter transitions into warmer weather across Missouri and Illinois, commercial roofs often carry damage that isn’t immediately visible from the ground.
Snow, ice, and fluctuating temperatures—often swinging 30-40°F within a single day during freeze-thaw cycles—can create small issues that go unnoticed until spring storms or summer heat make them worse.
At Jewett Roofing, we often see problems surface in spring that actually started months earlier during winter conditions.
A spring roof inspection is one of the most effective ways to catch these issues early and avoid costly repairs down the line.
Here’s what property managers should be paying attention to right now.
Winter Damage Isn’t Always Obvious
Winter weather can take a toll on roofing systems in ways that aren’t immediately visible.
Freeze-thaw cycles, snow load, and ice buildup can lead to:
- Loose or separated seams
- Damaged flashing around penetrations
- Stress at roof edges and corners
- Small punctures from ice or debris
These issues may seem minor, but they create entry points for water as conditions change.
In our experience, spring is when these hidden problems begin to show up—often after the first heavy rain.
Drainage Systems May Have Been Compromised
Drainage is one of the most important—and most overlooked—parts of a commercial roof.
After a winter season, it’s common to see:
- Blocked or slow-moving drains
- Debris buildup in scuppers and gutters
- Improper water flow or pooling areas
Standing water (ponding) that remains for more than 48 hours after a rain event can significantly accelerate membrane wear and increase the risk of leaks.
Ensuring that drainage systems are clear and functioning properly is a critical part of any spring inspection.
Early Signs of Membrane Wear
Before summer heat intensifies, spring is the ideal time to evaluate the condition of the roofing membrane.
Look for early indicators of wear, including:
- Surface cracking or brittleness
- Blistering or bubbling
- Shrinkage or pulling at seams
- Discoloration from UV exposure
UV exposure alone can reduce a roof’s lifespan by 20-30% over time if not properly maintained.
Addressing these issues early can extend the life of the roof and prevent more extensive damage during hotter months.
Small Issues Now Can Become Bigger Problems Quickly
One of the biggest risks this time of year is assuming everything is fine because there are no visible leaks—yet.
In reality, small vulnerabilities left over from winter can escalate quickly with:
- Spring rainstorms
- Increased temperature swings
- Prolonged sun exposure
What could be handled as a routine repair today can turn into a larger, more expensive issue if delayed.
We regularly work with property managers across Missouri and Illinois who catch these issues early—and avoid much larger repairs later in the year.
What a Spring Roof Inspection Should Include
A professional inspection goes beyond a visual check. It should include:
- Evaluation of seams, flashing, and penetrations
- Inspection of drainage systems and water flow
- Identification of membrane wear or damage
- Assessment of overall roof condition and attachment integrity
At Jewett Roofing, our inspections are designed to give property owners a clear understanding of current conditions—and a plan for what comes next.
The Bottom Line
Spring is a critical window for commercial roof maintenance.
Addressing winter damage, clearing drainage systems, and identifying early signs of wear can help prevent bigger issues as the seasons change.
If you’re unsure how your roof held up over the winter, a professional inspection can help identify issues before they become costly problems.
