Why El Monte Superior Roofing is the Best Choice for Thermal Imaging Roof Scans

Our thermal imaging roof scan services are specifically calibrated for El Monte's unique climate conditions. Located in the San Gabriel Valley, El Monte experiences extreme temperature variations that significantly impact roofing systems. With summer temperatures regularly exceeding 95°F and winter lows around 40°F, these thermal cycles create unique stress patterns on roofing materials that our infrared technology is specifically calibrated to detect. This is especially critical for commercial buildings along the I-10 corridor and in the Flair Park business district, where flat roofs absorb tremendous solar radiation.


El Monte's annual rainfall pattern—approximately 17 inches concentrated primarily between November and March—creates distinct moisture challenges that our thermal imaging can identify before visible damage occurs. Properties in the Mountain View neighborhood and along Lower Azusa Road are particularly vulnerable to hidden moisture infiltration due to their position relative to the Rio Hondo Watershed drainage patterns. Our thermal imaging technology is calibrated to detect temperature differentials as small as 0.5°F, essential for identifying subtle moisture patterns typical in El Monte's semi-arid microclimate zone 9b.


The diverse building stock throughout El Monte, from older residential properties in the Five Points area to newer commercial developments along Valley Boulevard, presents varied insulation challenges that thermal imaging uniquely addresses. Our scans comply with L.A. County Title 24 energy efficiency requirements, providing documentation that helps property owners verify compliance with local building codes while identifying specific energy loss patterns characteristic of El Monte's building types and orientation relative to our intense southern California sun exposure.

Thermal Imaging Roof Scan Services We Offer

We use cutting-edge thermal imaging technology to identify moisture, heat loss, and structural issues in roofs. Our services are tailored to different property types and include detailed inspection data to guide repairs and maintenance.

Commercial Roof Thermal Scans


For commercial buildings, our thermal imaging scans focus on large-scale roofing systems such as TPO, EPDM, and modified bitumen. We detect moisture trapped under membranes that can cause delamination or structural degradation.


Our team uses high-resolution infrared cameras, often FLIR E-Series or Testo 882 models, to map temperature variations accurately. This process helps prevent costly downtime by targeting problem areas after roof leak detection.


We also assess rooftop equipment areas and insulation integrity. Regular scans support facility managers in maintaining warranty compliance and extending roof lifespan. Our reports highlight areas needing immediate or future attention.

Residential Roof Thermal Scans


In residential settings, we inspect shingle, tile, and metal roofs for hidden moisture and insulation deficiencies. Thermal imaging reveals water infiltration under shingles and attic heat loss, which are not visible to the naked eye.


We tailor scans for homes using standard infrared cameras calibrated for common roof types like asphalt or clay tiles. This allows us to detect trapped moisture early, preventing mold and rot.


Our process includes roof surface surveys coupled with attic inspections to locate ventilation issues and thermal bridges. Homeowners receive actionable information to guide repairs and increase energy efficiency.

Customized Inspection Reports


Our inspection reports provide clear, annotated thermal images with precise temperature readings. We include summaries of detected anomalies with descriptions such as moisture presence, insulation gaps, or potential material failures.


Reports are designed for easy interpretation by property managers, contractors, or homeowners. We recommend specific repair methods and prioritize issues based on severity.


Documentation includes time-stamped images, roof section maps, and environmental conditions during the scan. This ensures accountability and helps track maintenance history for warranty or insurance purposes.

The Thermal Imaging Roof Scan Process

Our thermal imaging roof scan method is designed to accurately locate moisture in roofing systems with minimal disruption. We use precise timing and industry-standard technology to collect temperature data, then analyze it for actionable insight.

Scheduling and Preparation

We begin by coordinating the scan at a time ideally just after sunset. This timing allows the roof’s dry sections to cool faster in the night air, making wet areas more visible due to their retained heat. Customers should ensure that the roof surface is unobstructed and that any scheduled roof access permissions are in place.



Before the visit, we review building plans and previous maintenance records to anticipate challenging spots. Our team also confirms weather conditions, as clear evenings without rain are essential for accurate results. We prepare our equipment, including high-resolution infrared cameras and temperature sensors calibrated for diverse roofing materials found in commercial and residential properties..

On-Site Roof Scanning

At the site, we use infrared cameras to scan the entire roof surface systematically. We focus on detecting thermal differences that indicate moisture retention beneath roofing membranes or insulation. The scan covers all critical roofing components, such as seams, flashing, and penetrations, that are common entry points for water.



Our team captures thermographic images and videos, paying close attention to areas with temperature anomalies. These images reveal moisture intrusion that’s invisible to the naked eye. This process is non-invasive, requiring no physical roof disassembly, which protects your roofing assets while delivering precise diagnostics.

Post-Scan Analysis and Recommendations

After completing the scan, we review the collected thermal images using specialized software that enhances detection accuracy. We map out the affected zones and assess the severity of water intrusion along with possible sources like leaks or condensation.



Our detailed report outlines findings, including exact location coordinates and images, enabling targeted repairs. We recommend options ranging from focused patching to broader repairs when necessary. This tailored approach helps avoid unnecessary roofing replacement and supports effective budget planning for building owners and managers.

Frequently Asked Questions About Thermal Imaging Roof Scan

  • How much does a commercial roof thermal imaging scan cost?

    Commercial thermal imaging roof scans cost $0.02-$0.06 per square foot, with minimum fees starting at $750-$1,000. A standard 10,000 sq ft scan costs approximately $800-$1,200. Pricing varies based on roof complexity, accessibility, report requirements, and inspection method. Advanced moisture mapping with FLIR E-Series equipment adds 15-20% to base costs. Multi-building assessments qualify for volume discounts.

  • Who provides infrared roof inspections for commercial buildings in El Monte?

    We provide infrared roof inspections throughout El Monte and the San Gabriel Valley. Our certified thermographers hold Level II certification through the Infrared Training Center and use FLIR T-Series thermal imaging systems. We specialize in scanning TPO, EPDM, modified bitumen, and built-up roofing systems. Our inspection protocols comply with ASTM C1153 standards for locating wet insulation in commercial roofing systems.

  • How long does a thermal imaging roof scan take for a large commercial property?

    Thermal imaging scans for large commercial properties typically take 3-5 hours for buildings up to 50,000 square feet. Complex roofs with multiple levels or extensive equipment require 20-30% more time. Our process includes visual inspection, thermal imaging with FLIR or Fluke equipment, verification testing, and documentation. Same-day preliminary results are provided, with comprehensive reports delivered within 48 hours.

  • When should businesses schedule thermal roof scans to detect moisture issues?

    Businesses should schedule thermal roof scans biannually - in late spring to detect winter damage and early fall before rainy season. For optimal results, scans should be conducted after sunset when the roof has cooled, creating maximum thermal contrast between dry and wet areas. Emergency scans following storms or suspected leaks are recommended regardless of season. Aging roofing systems (10+ years) benefit from quarterly scans.

  • Will a thermal roof scan detect all leaks in my commercial building?

    Thermal imaging detects approximately 85-90% of active moisture intrusion within commercial roofing systems, particularly in insulated membrane and built-up systems. The technology excels at locating trapped moisture beneath membranes and within insulation layers. For comprehensive detection, we combine thermal imaging with electrical capacitance testing (Tramex), core sampling, and electronic leak detection (ELD) in critical areas for the most accurate assessment possible.
