Commercial roofs are built to last, but even the strongest systems can face problems over time due to weather, poor maintenance, or installation errors. Knowing how to identify and fix these issues early can save property owners thousands of dollars in repairs and energy costs.
H2: 1. Roof Leaks and Moisture Damage
H3: The Problem
Leaks are among the most common issues in commercial roofing. They often result from damaged flashing, aging materials, or punctures caused by foot traffic or debris. Over time, water infiltration can lead to mold growth and insulation damage.
H3: The Solution
Regular inspections and immediate patch repairs are key. For single-ply systems like TPO or EPDM, leaks can often be sealed using compatible membrane patches and adhesives. For built-up or modified bitumen roofs, resealing or applying a new protective coating can stop water intrusion effectively.
H2: 2. Ponding Water
H3: The Problem
Flat commercial roofs are prone to ponding — water that sits for more than 48 hours after rain. This can accelerate membrane deterioration and increase the risk of leaks.
H3: The Solution
Ensure proper drainage by cleaning gutters, downspouts, and scuppers regularly. If ponding persists, a roofing contractor may recommend re-sloping or installing tapered insulation to improve runoff.
H2: 3. Blistering and Bubbling
H3: The Problem
Blisters form when air or moisture gets trapped between roof layers, especially in asphalt-based systems. Left untreated, they can rupture and expose the substrate to the elements.
H3: The Solution
Small blisters can often be cut, dried, and resealed with bitumen and a patch. However, widespread blistering may indicate poor ventilation or water damage beneath the membrane, requiring partial replacement.
H2: 4. Damaged Flashing
H3: The Problem
Flashing protects roof penetrations like vents, skylights, and HVAC units. When flashing cracks or separates, water can easily enter the building.
H3: The Solution
Inspect flashing joints during every maintenance cycle. Re-secure loose sections with roofing cement or replace deteriorated flashing altogether. For long-term protection, consider installing flexible metal or thermoplastic flashing materials that resist corrosion.
H2: 5. Shrinkage and Cracking
H3: The Problem
EPDM and other single-ply membranes can shrink over time due to temperature changes and UV exposure. This shrinkage can pull seams apart or cause surface cracking.
H3: The Solution
Routine roof coating applications can protect the membrane from UV rays and extend its lifespan. When shrinkage becomes severe, the affected sections should be replaced and re-anchored to prevent further stress on the roof system.
H2: 6. Poor Installation or Maintenance
H3: The Problem
Even high-quality materials will fail if the installation was rushed or handled by inexperienced contractors. Common signs include uneven seams, loose fasteners, or premature deterioration.
H3: The Solution
Always hire certified commercial roofing professionals. Regular preventive maintenance — at least twice a year — ensures that potential problems are detected before they escalate.
H2: Conclusion
Proactive maintenance and professional inspections are the best defense against costly commercial roofing problems. Addressing minor issues early can extend the life of your roof and protect your business investment for years to come.
