Commercial Roof Leak Detection Services We Provide

Early detection saves money and prevents extensive damage to your commercial property. Our specialized equipment and trained technicians identify leaks quickly so you can address problems before they worsen.

Thermal Imaging Inspections


We use professional thermal imaging cameras to detect temperature differences that indicate moisture and leaks in commercial roofing systems. This technology shows us exactly where water is entering your building, even when leaks are not visible to the naked eye.


Our thermal scans work on all flat roof types and help us create accurate repair plans based on actual leak locations. These non-invasive inspections save time and money by pinpointing problems without unnecessary roof removal or exploratory work.

Electronic Leak Detection


Our electronic leak detection equipment sends low-voltage electrical currents through your roof membrane to locate holes, cracks, and damaged areas precisely. This method works especially well on single-ply roofing systems like TPO, PVC, and EPDM, where small punctures can cause significant water damage.


We mark all detected leak points and provide you with a detailed map showing exactly where repairs are needed. This scientific approach ensures we find every leak source so repairs are complete and effective the first time.

Moisture Testing and Analysis


We perform comprehensive moisture testing using calibrated moisture meters that measure water content in roofing materials, insulation, and structural components accurately. Our technicians check multiple areas across your roof to identify patterns that indicate ongoing leaks or areas at risk for future problems.


This testing helps us determine if insulation replacement is needed and whether structural damage has occurred from water infiltration. Detailed moisture analysis prevents mold growth and helps maintain healthy indoor air quality for your employees and customers.

Why Choose Our Professional Leak Detection

Professional leak detection saves you money and protects your commercial property investment long-term. Our systematic approach identifies all leak sources so repairs address root causes instead of just visible symptoms.

Advanced Technology Benefits


Professional thermal imaging and electronic detection equipment costs thousands of dollars and requires specialized training to operate correctly and interpret results accurately. Our investment in this technology means you get precise leak location without guesswork or extensive roof removal that increases repair costs. 


Comprehensive Documentation


We provide detailed written reports with photos, thermal images, and leak location maps that help you prioritize repairs based on severity and budget. Our documentation includes recommendations for immediate repairs versus items that can be scheduled for regular maintenance cycles without emergency action. 


Insurance and Warranty Support


Our certified leak detection services provide documentation that insurance companies and roofing manufacturers require for claims processing and warranty validation. Professional inspection reports demonstrate that you are maintaining your commercial roof properly, which can prevent warranty voidance due to neglect. 

Common Leak Locations and Causes

Understanding where leaks typically occur helps property managers spot warning signs and schedule inspections before problems worsen. Our experience shows that certain roof areas require more attention due to design factors and weather exposure.

Roof Membrane Seams


Seams where roofing membrane sections join together are common leak points because they rely on proper installation and ongoing maintenance to remain watertight. Temperature changes cause membrane materials to expand and contract, which can stress seam bonds and create small openings over time. Our thermal imaging easily identifies seam failures because water infiltration creates temperature differences that show up clearly on infrared cameras. Regular seam inspection and maintenance prevent small seam issues from becoming large repair projects that require membrane replacement.

Flashing and Penetrations


Areas where pipes, vents, HVAC equipment, and other items penetrate the roof membrane require special flashing systems that can fail due to weather exposure. Flashing around roof drains, skylights, and equipment supports experiences constant temperature cycling and UV exposure that can cause cracking or separation. Our electronic leak detection excels at finding small holes around penetrations where water enters but may not be visible during visual inspections. Proper flashing maintenance is critical because penetration leaks often cause the most expensive interior damage when water enters electrical or mechanical systems.

Drainage Systems


Clogged drains and gutters cause water to pool on flat roofs, which increases pressure on membrane seams and can create new leak points. Our moisture testing identifies areas where standing water has saturated insulation or caused structural damage that requires immediate attention. Drainage problems also accelerate roof aging because constant moisture exposure breaks down roofing materials faster than normal weathering processes. Regular drain cleaning and inspection prevent most drainage-related leaks and extend overall roof life significantly through proper water management.

FAQs About Our Commercial Roof Leak Detection

  • How much does commercial roof leak detection cost?

    Detection costs depend on roof size and building complexity but typically range from $300 to $800 for most commercial properties. Professional detection saves money by preventing expensive emergency repairs and interior damage from undetected leaks.

  • How long does a leak detection inspection take?

    Most commercial leak detection inspections take 2-4 hours depending on roof size and the number of suspected problem areas. We provide same-day results with detailed reports and repair recommendations for immediate action planning.

  • Can you detect leaks during rainy weather?

    We can perform limited leak detection during light rain, but thermal imaging works best in dry conditions for accurate results. Moisture from recent rain can interfere with some detection methods, so we recommend scheduling inspections during clear weather when possible.

  • Do you provide repair services after finding leaks?

    Yes, we provide complete leak repair services for all commercial roofing systems including emergency repairs and scheduled maintenance work. Our 28 years of experience means we can fix any leak problems we discover during detection inspections.

  • How often should commercial roofs be inspected for leaks?

    We recommend annual leak detection inspections for roofs under 10 years old and twice-yearly inspections for older roofing systems. Regular inspections catch problems early and prevent expensive emergency repairs that disrupt business operations.
