Comprehensive Commercial Roof Inspection Services

We deliver thorough inspections that identify all relevant issues affecting your commercial flat roof. Our approach covers every aspect necessary to assess the condition, functionality, and safety of your roofing system, ensuring no detail is overlooked.

Full Roof Assessment Procedure

Our inspection begins with a detailed visual survey, both on the roof surface and from ground level, using binoculars and high-resolution cameras. When appropriate, we deploy drone technology to capture aerial views, allowing us to identify hard-to-reach damage or irregularities.


We use infrared thermography to detect moisture accumulation and possible leaks beneath the roofing membrane. This non-destructive technique highlights areas with trapped water, which could lead to structural decay or mold growth.


Documenting all findings, we generate a comprehensive condition report including photographs and maps of affected zones. This report serves as a critical reference for our other services such as commercial flat roof repair, maintenance planning, or insurance claims.

Inspection of Roofing Systems and Materials

We assess the specific roofing materials installed on your commercial flat roof, such as TPO, EPDM, PVC membranes, modified bitumen, or built-up roofing (BUR). Each material requires unique evaluation criteria for wear, seam integrity, and puncture resistance.



Our team checks for membrane degradation due to UV exposure, chemical spills, or thermal cycling. We also inspect flashing, sealants, and fasteners to ensure all components maintain waterproofing standards.


Special attention is given to installed rooftop equipment interfaces and penetrations to prevent potential leak points. Our experience with various brand systems allows us to recommend the best repair methods based on material composition and warranty considerations.

Evaluation of Drainage and Structural Integrity

Proper drainage is vital to a commercial flat roof’s performance. We examine scuppers, gutters, internal drains, and downspouts to confirm they function without blockage or corrosion, preventing water ponding which accelerates roof deterioration.



Our structural review includes an inspection of the roof deck, support joists, and insulation layers. We look for signs of sagging, deflection, rust on metal decks, or compromised insulation that reduces energy efficiency.


We also evaluate rooftop load capacity, especially if modifications have been made or heavy equipment is present. This ensures the roof can safely bear current and future demands without risking structural failure.

Common Issues Identified During Roof Assessments

During our roof inspections, we focus on critical problem areas that can compromise the roof’s integrity. These include physical damage from weather, water penetration risks, and material deterioration over time. Identifying these issues early allows us to recommend precise repairs or maintenance to extend the roof’s lifespan.

Storm Damage

Storm damage often results in loose or missing roofing materials such as membrane panels, flashing, or fasteners. We conduct detailed inspections to find punctures, lifted seams, and damaged drains caused by wind uplift or hail impact. Immediate repairs are essential to prevent further structural damage and water infiltration.



Our team uses infrared imaging and moisture detection tools to identify hidden damage below the surface, which can go unnoticed during visual checks. We prioritize safe, fast interventions after storms to restore the roof’s weatherproof barrier and avoid costly downtime for your business.

Water Intrusion

Water intrusion is one of the most frequent and damaging roofing issues. Leaks often develop around penetrations like vents, HVAC units, or flashing areas that have deteriorated or were improperly sealed. We use thermal imaging and moisture scanning to pinpoint exact leak locations without unnecessary removal of roofing materials.



We address ponding water by regrading low spots or installing tapered insulation systems to ensure efficient drainage. Standing water accelerates membrane degradation and can cause structural stress, so eliminating it is a key part of our assessment and repair strategy. Our solutions emphasize long-term prevention to maintain a watertight roof envelope.

Aging and Wear

Commercial roofing materials naturally degrade due to UV exposure, temperature cycles, and general use. Membranes like TPO, EPDM, or modified bitumen may show signs of cracking, blistering, or adhesion loss as they age. We assess the condition of insulation and reflective coatings to determine if upgrades can improve energy efficiency and extend roof life.



Our approach involves determining whether restoration or complete replacement is necessary based on wear severity. We minimize disruption by using durable materials and manufacturer-approved techniques. Regular maintenance recommended by our team can delay costly replacements and optimize the roof’s performance for years.
