Common Roof Defects

Membrane Punctures and Tears

One of the most frequent issues discovered during a commercial roof inspection is damage to roofing membranes. Whether your building has EPDM, TPO, PVC, or modified bitumen, these materials can develop punctures and tears from foot traffic, fallen debris, or improper installation. These openings allow water to penetrate beneath the membrane, causing insulation damage and interior leaks.

Improper Flashing Installation

Flashings are critical components that seal transitions between the roof and vertical surfaces like walls, curbs, and penetrations. During a thorough commercial roof inspection, professionals often find improperly installed or deteriorated flashings. This defect accounts for nearly 80% of all roof leaks and can significantly reduce a roof’s lifespan if not addressed promptly.

Standing Water and Poor Drainage

Commercial flat roofs are particularly susceptible to ponding water, which occurs when water remains on the roof surface for more than 48 hours after rainfall. A professional commercial roof inspection will identify drainage issues caused by clogged drains, inadequate slope, or structural deflection. Standing water accelerates membrane deterioration and can add significant weight to the roof structure.

Aging and UV Degradation

Over time, all roofing materials deteriorate from exposure to the elements. UV radiation causes membranes to become brittle and crack, while thermal cycling leads to expansion and contraction that weakens seams. Regular commercial roof inspection helps identify areas showing signs of advanced aging before they fail completely.

Open Seams and Failed Sealants

Seam failures are commonly identified during commercial roof inspection services. Whether heat-welded, adhered, or sealed, these connection points between roofing materials are vulnerable to separation. Similarly, sealants around penetrations and terminations deteriorate over time, creating entry points for moisture.

Contractor Damage

Surprisingly, many roof problems stem from other tradespeople working on the roof. HVAC maintenance, antenna installations, and other services can inadvertently damage roofing materials. A scheduled commercial roof inspection program helps identify this damage before it leads to significant problems.

Preventative Measures

Implementing a regular commercial roof inspection schedule is the most effective way to prevent these common defects from causing major failures. Biannual inspections, especially after severe weather events, allow for early detection and repair of minor issues before they escalate into costly problems.
