For commercial property owners and facility managers, a proactive approach to roofing maintenance can save thousands of dollars in repairs, extend the lifespan of the roof, and preserve the safety of the building’s occupants. One of the most effective tools in this approach is a professional roof inspection. But what exactly happens during an inspection, and what do roofing contractors look for when assessing the condition of a commercial roof? Understanding what we find in commercial roof inspections can help you make informed decisions about your building’s roofing system.

The Importance of Regular Roof Inspections
Commercial roofs are built to be durable, but they are still vulnerable to the elements, structural shifts, and everyday wear and tear. Scheduled inspections help identify small issues before they turn into major, costly problems. In a coastal environment like Santa Monica, CA, buildings are exposed to a combination of intense sunlight, moisture, and salt in the air—all of which accelerate roof degradation.
By scheduling inspections at least twice a year—ideally in spring and fall—businesses can protect their investment, meet warranty requirements, and ensure a safe working environment inside the facility.
Exterior Surface Evaluation
One of the first things contractors examine during a commercial roof inspection is the surface of the roof itself. Whether the system is flat or sloped, the surface must be clear of debris, standing water, or damage. Inspectors look for cracks, punctures, blistering, and worn membrane areas. On flat commercial roofs, ponding water is a major concern. If water isn’t draining properly within 48 hours after rain, it can weaken the membrane and lead to leaks or structural damage.
Roofing experts also check the condition of the roofing material—whether TPO, EPDM, modified bitumen, or metal—for signs of aging, such as brittleness, discoloration, or UV damage.
Flashings and Penetrations
Areas where pipes, vents, HVAC units, or skylights penetrate the roof are common trouble spots. Flashings are installed around these penetrations to seal and protect them from leaks. During an inspection, flashings are closely reviewed to ensure they are securely attached and free from rust, gaps, or separation.
Improper or failing flashings are among the most frequent sources of roof leaks on commercial buildings. Detecting issues early can help avoid water intrusion and interior damage that often goes unnoticed until it’s severe.
Drainage Systems
A functioning drainage system is vital for maintaining the integrity of a commercial roof. Inspectors will assess gutters, downspouts, scuppers, and internal drains to make sure water flows off the roof efficiently. Clogs caused by debris, leaves, or accumulated dirt can back up water and cause structural deterioration, particularly in low-slope systems.
Regular cleaning and inspection of these components are crucial, especially during the fall and after major storms, when drainage systems are most vulnerable.
Interior Inspection and Signs of Water Damage
A thorough commercial roof inspection also includes checking the building’s interior. Inspectors will look for signs of roof leaks, such as water stains on the ceiling, mold growth, bubbling paint, or soft spots in drywall. These indicators often point to hidden roofing problems that might not be visible from the surface.
Thermal imaging tools may also be used to detect trapped moisture beneath the roof membrane or insulation. This moisture can reduce energy efficiency and cause long-term damage if not addressed quickly.
Roof Edge and Perimeter
The perimeter of the roof, including edges and parapet walls, is another critical area. Inspectors will check for secure edge flashings, tears, or separation between different roof sections. These areas are often subject to wind uplift and weather stress, making them more susceptible to damage.
A compromised roof edge can allow wind-driven rain to enter the structure, especially during seasonal storms in Santa Monica.
Assessment of Roofing Attachments and Equipment
Many commercial roofs support mechanical systems like HVAC units, solar panels, or satellite dishes. The mounting points for these systems are closely evaluated to ensure they’re not damaging the membrane or causing structural stress.
Inspectors will check for shifting equipment, improper installations, or corrosion around metal components. If equipment is not properly supported, it can puncture the roofing surface and compromise the waterproofing layer.
Documentation and Recommendations
After the inspection, a reputable roofing contractor will provide a detailed report, including photographic documentation and a list of findings. The report should also include repair recommendations, maintenance suggestions, and estimated timelines for service.
This document is invaluable for tracking the roof’s condition over time, planning budgets, and maintaining compliance with manufacturer warranties and insurance policies.
