Commercial Roofing Maintenance Mistakes to Avoid

Maintaining a commercial roof is a year-round responsibility, and neglecting even the smallest details can lead to costly repairs, downtime, or premature failure. In Santa Monica, CA, where buildings face salt air, sun exposure, and seasonal weather changes, avoiding common roofing mistakes is critical for asset protection. At Economy Roofing, we’ve seen how a lack of maintenance or improper care can shorten a roof’s life by years.

In this blog, we highlight the most frequent commercial roofing maintenance mistakes—and how to avoid them to maximize your roof’s lifespan and performance.

Mistake #1: Skipping Regular Inspections

One of the most common missteps is waiting until there’s a leak to inspect the roof. By then, water may have already caused structural or interior damage.

Solution:

Schedule professional roof inspections at least twice a year—ideally in spring and fall—and after severe storms. Proactive checks help detect wear, membrane punctures, or loose flashing before they become major issues.

Mistake #2: Delaying Minor Repairs

Small problems like cracks, open seams, or clogged drains may seem harmless, but they can escalate quickly.

Solution:

Address minor issues as soon as they’re discovered. Routine maintenance often costs a fraction of what emergency repairs or full replacements do.

Mistake #3: Allowing Foot Traffic Without Precautions

HVAC technicians and maintenance crews often walk on commercial roofs. Without proper pathways, their foot traffic can damage membranes or create punctures.

Solution:

Install walkway pads or designated traffic paths, especially near equipment areas. Educate service personnel on where and how to walk safely on the roof.

Mistake #4: Improper Drainage Maintenance

Pooling water accelerates membrane deterioration and increases the risk of leaks. Blocked drains and scuppers are a leading cause of standing water.

Solution:

Regularly clear drains, gutters, and scuppers of debris. Make drainage inspection part of your routine maintenance checklist.

Mistake #5: Ignoring Manufacturer Guidelines

Failure to follow manufacturer maintenance protocols may void your roof’s warranty. Brands like Malarkey and Owens Corning outline specific requirements for inspections and repairs.

Solution:

Partner with a certified contractor who understands and adheres to your roof system’s warranty terms. Keep detailed records of maintenance to support future claims.

Mistake #6: DIY Repairs or Hiring Unqualified Contractors

Commercial roofs are complex. Unlicensed repairs or patch jobs can cause more harm than good and often don’t comply with building codes.

Solution:

Always hire experienced commercial roofing professionals with a proven track record. Vet them for proper licensing, insurance, and manufacturer certifications.

Final Thoughts

Avoiding these common commercial roofing mistakes can mean the difference between a long-lasting investment and early failure. A well-maintained roof protects your operations, inventory, and peace of mind.
