11 Common Commercial Roof Problems and Solutions

Keep commercial roofing problems from turning into leaks and costly repairs. Knowing what commercial roofing problems to watch for and what action to take can prevent severe roof damage.

New Image Roofing Atlanta explores 11 reasons commercial roofs develop significant problems and how to efficiently solve them.

• ✕Problem: Low spots or poor drainage cause water to pool for more than 48 hours after rainfall.
• ✔Solution: Regrade insulation, clear blocked drains, and install tapered insulation systems to promote water flow.

• ✕Problem: Flashing seals the edges, penetrations, and transitions on a roof. Damaged flashing allows water to infiltrate.
• ✔Solution: Inspect flashing regularly and replace any sections showing cracks, warping, or separation.

• ✕Problem: Foot traffic, dropped tools, or debris can puncture a membrane, letting moisture penetrate.
• ✔Solution: Install walkway pads for foot traffic and repair punctures immediately with manufacturer-approved patches.

• ✕Problem: Leaves, debris, and sediment block water flow, causing overflows and leaks.
• ✔Solution: Schedule regular drain and gutter cleanings to ensure continuous proper drainage.

• ✕Problem: Inexperienced installers may leave seams unsealed or components misaligned.
• ✔Solution: Hire certified, experienced commercial roofing contractors and conduct post-installation inspections.

• ✕Problem: Seams between membrane sheets can loosen over time due to thermal expansion and contraction.
• ✔Solution: Seal open seams promptly using compatible adhesives or heat-welding methods.

• ✕Problem: Trapped moisture or air beneath the membrane causes raised blisters that weaken the roof surface.
• ✔Solution: Remove blistered sections, repair the substrate, and reinstall the membrane (following the manufacturer’s specifications).

• ✕Problem: HVAC units, vents, skylights, and other penetrations are common issues when flashing or seals fail.
• ✔Solution: Inspect all penetrations during routine maintenance and reseal or replace components when deterioration appears.

• ✕Problem: Aging or poor-quality materials can shrink and pull away from edges and flashing.
• ✔Solution: Replace affected sections and upgrade to a higher-grade membrane with proper expansion capability.

• ✕Problem: Building settling or structural shifting can crack roofing materials or break seals.
• ✔Solution: Use flexible roofing materials that can accommodate slight building movement and repair damaged areas quickly.

• ✕Problem: Constant exposure to sunlight degrades roofing materials, making them brittle and prone to cracking.
• ✔Solution: Apply reflective roof coatings and replace damaged sections to extend the roof’s life.
