How to Fix Leaking Commercial Roofs: 1 Minute to Solve Your Roof Issues

Fixing leaking commercial roofs is essential to protect your building’s structural integrity and prevent costly damage. A leak can be caused by age, weather, poor installation, or inadequate maintenance. Here’s a step-by-step guide to help you address the issue:

1. Inspect the Roof

Begin by performing a thorough inspection. Look for signs of ponding water, cracks, bubbles, damaged flashing, or punctures in the membrane. Inspection is especially important after heavy rain or storms.

2. Identify the Source of the Leak

Assess the area below the leak for water stains, mold, or dampness. Trace the path back to the roof surface to locate the entry point. Sometimes water travels along beams or insulation before appearing indoors, so checking adjacent areas is critical.

3. Clean and Prepare the Surface

Remove debris, dirt, and any standing water. Dry the area before attempting repairs, as proper adhesion of sealant or patch materials requires a clean and dry surface.

4. Patch Small Leaks

For minor leaks or punctures, apply a commercial-grade roofing sealant or patch kit designed for your roof’s specific material (TPO, EPDM, PVC, or metal). Follow the manufacturer’s instructions for best results.

5. Repair or Replace Flashing

Damaged or corroded flashing can let water seep through. Replace sections of flashing as needed and seal joints with appropriate waterproofing compounds.

6. Deal with Larger Damage

If the damage is extensive, such as a large tear in the membrane, warped panels, or recurring leaks, consider replacing the affected section or scheduling professional help. Temporary patches can buy you time, but they shouldn’t replace full restoration.

7. Maintain Regular Roof Checks

Routine maintenance prevents leaks by spotting early signs of wear and tear. It’s wise to establish a maintenance schedule, especially for older roofs or those in areas prone to severe weather.

As a designer, I always prioritize effective drainage and surface planning in commercial roof projects. Advanced roof planning tools can help you visualize and optimize commercial spaces, reduce risks of leaks, and select the best waterproofing solutions before implementation. Leveraging digital solutions like a 3D Floor Planner ensures precise roof layouts and effective long-term fixes for leaks.

Tips 1:

Consider upgrading to high-quality roofing materials with longer lifespans when making repairs, and use reflective coatings to improve energy efficiency and reduce weather-related damage. Consulting a professional is recommended for complicated leaks or large areas of damage.

FAQ

Q: What is the most common cause of leaks in commercial roofs?

A: Common causes include age-related wear, poor installation, damaged flashing, and lack of regular maintenance.

Q: Can I repair a commercial roof leak myself?

A: Minor leaks can usually be patched with sealants or kits, but larger or recurring leaks should be addressed by professionals.

Q: How often should a commercial roof be inspected?

A: Twice a year is standard (spring and fall), plus after major storms.

Q: Are there preventative measures to avoid future leaks?

A: Yes, routine maintenance, clearing debris, and upgrading flashing are effective preventative steps.

Q: Should I repair or replace a leaking commercial roof?

A: If the damage is confined to a small area, repairs may suffice. For extensive damage or frequent leaks, replacement is more cost-effective long term.
