We had the privilege to work with JP King Auction Company to capture photos of 19 lots for a development in Greenville, TX going up for auction soon. They provide land auctions all over the country for developers ready to off load open lots for sale. To market the properties effectively, they must have up to date, quality photos of the lots and overall property showing highlights and selling points. We captured aerial photos of the entire property as well as highlighting the sections of available lots left for sale. They wanted to see photos of the creeks and areas where lots have already been developed and people already call home. Most of the open lots remaining are cleared and make perfect equestrian properties. This community is located just south of town right off of US Highway 281. Here are a few more photos from the shoot and provide an example of how we can help others in the great state of Texas highlight properties for marketing purposes! Drones are perfect for the job and we are always willing to travel to get the job done right the first time.

We recently worked with Geo Solutions out of Kensington, PA on a project in Greenville, TX document the progress of a mostly completed dam project. We capture aerial photos and various video of the project for marketing purposes. Geo Solutions was looking for a unique perspective to showcase there work to other prospective clients in the future. They provide meticulous and timely work on every project and we are happy to help them show off their work! Tarillo Vue’s capabilities dont just start and stop at helping to provide unique marketing materials. We also help provide inspections services for projects like this.
For this project, we utilized the DJI Matrice 210RTK with the zenmuse X4S. We were able to capture video footage in 4k at 60 frames per second and took 20mp still shots. This drone is capable of a dual camera payload allowing us to also fly with a thermal camera. Redundant internal systems ensure it flies safely and captures smooth, stable photos consistently without dealing with heavy magnetic interference.
The capabilities of this drone would give us the ability to help out with much more than just creative aerial photography and videography. The use of high resolution thermal and standard imagers can ensure the Dam is strong and solid throughout. If moisture was able to get through the back side of the Dam, we would be able to identify it with ease. Having this peace of mind helps to reduce liability by having peace of mind the project is completed properly.

The most recent buzz on the street is that “storm created openings are the only thing that gets paid in Texas. High resolution inspection, thermal by air and by hand, coring to prove the findings.” As professionals in the industry, no matter what your role is, you are always looking for new tools to add to your belt to help make your job easier and prove roof conditions clearly to the property owner or insurance provider. The insurance providers are now making the phrase “a picture speaks a thousand words” a reality, meaning you have to provide them with the evidence that most clearly reveals and proves moisture!
The evidence you gather helps you determine if an insurance or warranty claim is possible or decide if the roof can be repaired or replaced. Gathering this data and information to make an educated decision often comes at a cost, but in most situations, can save property owners and other companies a lot of time and money. There are many professionals in the commercial roofing industry. Many of them are not even directly involved in handling the repair or replacement of a roof system. Public insurance adjusters, lawyers, engineers, inspectors and obviously roof construction companies are just to name a few. All of these professions utilize a “set of tools” to accomplish there job efficiently and effectively…
Physically walking and inspecting the roof will never be replaced as the best way to gather hard data on roofs. You can identify problems from the surface where there is ponding water and soft spots under the roof system. You can then follow up your suspected problem areas with core sampling to learn the roofs construction and identify if there is moisture present in those areas. Other methods also include the use of moisture probes and dec scanners.
All of these tools are necessary for effectively performing a complete study on a roof. But why would you spend hours inspecting an entire roof for minor details when you can now collect evidence to help you narrow in on where your search needs to take place? Thermal imaging is not a new technology, but there are new and unique ways to deploy the technology to gather more data quicker and safer than ever before.
New Tools – Drone and Plane Thermal Inspections
Drones. The buzz word across many industries today. If you are a professional in the roofing industry and your business does not take advantage of drone technology, you are really missing out on a resourceful opportunity to help your clients. Drones can provide you with a perspective you would not have otherwise obtained. You can drastically reduce risk by targeting specific areas for physical inspection to save time spent on a roof.
Drone technology has come a long way since they were first introduced just a few years ago to the marketplace for professional application. Longer battery life, better cameras, and even the implementation of thermal imaging on drones have made it’s capabilities unmatchable compared to alternative inspection and data collection methods.
So what can it do? Drones can capture both thermal and visible images of a roof for detailed review and inspection. This data helps you narrow in on where problems exist within the roof system. This collection of data can be used to:
estimate costs for repair or replacement.
process detailed reports to prove conditions in legal or insurance battles.
calculate if 20% or more of the roof is compromised.
learn where physical inspections should be conducted based on the thermal scans.
perform moisture and core sampling to verify suspected moisture.
TPO (Thermoplastic Roof Systems) roofs are typically white, can be mechanically fastened, fully adhered or point affixed applications, contain various types of insulation, and are well adapted for harsh weather climates. The material is highly reflective. In warmer climates, property owners can qualify for tax breaks by using these roof systems on commercial properties in efforts to help reduce energy consumption. Due to the reflective nature, these roofs can be hard to image with thermal cameras and many thermographers are scared to take on these roofs. Because most of the heat is reflected, it cools off faster than other roof systems after the sun sets. Just because these roofs are challenging and reflective does not mean they are impossible to inspect. Catching the roof at just the right time and utilizing an experienced thermographer will give you the desired results for the inspection.
EPDM (Ethyline Propolyne Diene Terpolymer) roofs are a single ply rubber membrane that is highly tolerable of harsh weather conditions such as hail and heavy sunlight. These systems can be ballasted, mechanically attached, or fully adhered. These roof systems, like TPO’s, can be difficult to inspect due to the nature of the membrane’s composition. Just like with TPO roofs, many thermographers are afraid of these roofs due to the difficulty of getting the right information, but with the proper time and conditions, along with an experienced thermographer, the appropriate data can be collected for the inspection.
BUR (Gravel Built Up Roof Systems) roofs are comprised of multiple layers including felts, fabrics, or mats that are laminated together with bitumen, with either asphalt or coal tar pitch. The application incorporates alternating layers of plies and bitumen and the surface is layered with a gravel application, mineral cap sheet, or a weather resistant coating. These roofs present a different set of challenges for thermal imaging. Since many of these roofs are typically covered with gravel, the displacement of heat in the cooling process is different and can be hard to locate. We often recommend that the areas of concern are cleared before a thermal inspection is performed, but a roof scan can be conducted with an experienced thermographer and proper conditions.
Mod Bit (Modified Bitumen Roof) roofs area blend of old and new technology to bring you an elite roof system that is highly resistant to physical abuse and heavy foot traffic. These systems are comprised of asphalt reinforced by either polyester or fiberglass. Two different polymers APP (Atactic Polypropylene polymer) and SBS (Styrene Butadiene Styrene) are used to modify the elasticity and temperature flexibility of the membrane. Of the roof systems that exist that are capable of being inspected, this one is the most friendly of them all.
Provide in House or Contract Out
So now your probably thinking this is a pretty cool resource and you want to take advantage of it, right? You have 2 options. Either take on the technology in house or contract it out to a professional. There are obviously pros and cons to both options.
Thermography is more than just taking a picture of a roof and identifying where water is. You have to understand the science of it to effectively capture what is inside the roof and know how to interpret it. The camera’s job is to identify temperature differences on the surface of the roof, not specifically identify water inside it. This means there are many variables that come into play and other objects and atmospheric conditions that can create false exceptions that the inexperienced eye would not be able to differentiate.
In order for your drone thermal inspections to be reputable, stand up in court, be valid in an engineering report or in insurance eyes, you must have your level 1 (or better) thermographers certification along with a good understanding of what your doing. The last thing you want to do is put together a report with false information. For legal drone operations you must have your UAV pilots license and follow the rules under Part 107 set by the FAA. Anyone who has the slightest understanding of thermal imaging knows you have to perform your inspections in the evening just after dark. The FAA prevents you from being able to do so unless you have a waiver to operate at night, 107.29 Daylight Operation. Flying a drone is not as simple as many think. Providing the service in house requires a lot of time and effort to do it right. If this is the route you pursue, I highly encourage you to do it right. Where problems arise flying drones “illegally” is in the event something goes wrong. If a lawsuit arises from suspected peeping or the drone crashes causing personal injury or property damage, your insurance will not cover you if you do not have proper insurance or have proper licensing and authorization from the FAA.
Bringing drone services in house has the potential to save your company time and money. We can assist you in determining whether your company is large enough to realize the savings. Many companies have implemented successful in house programs, but it is not always appropriate.
Alternatively, you can work with professionals who are already setup and established to do the job right with proper certifications and knowledge. This allows you to provide a valuable service and means your following the rules. This route can be more costly over time, but can save you a lot of time and headache implementing a new program when your main focus is selling roofs, working with insurance companies, and processing engineering reports for your client. It is difficult to be a jack of all trades and be the expert at them all.

North Texas has been getting a lot of rain lately. If you study this aerial photo closely, you can probably guess that all the water pictured should not be here. Many people near the main rivers and lakes have experienced high water levels. This is a flooded construction site outside of Rosser, TX right along the Trinity River. The river levels got so high that it flooded this 60′ deep construction site and everything that was in it. The yellow crane sticking out of the water is a good indication of the hundreds of thousands of dollars worth of assets and equipment that are submerged under the water. The engineer suspects it will take roughly 2- 3 weeks to drain the water from this site, delaying this project for potentially months.
The construction company wanted to use a drone to capture legal documentation of the flood levels for insurance purposes. We will be back on site as soon as the water has receded to document what equipment and assets are totaled due to the flooded site. The construction company will be able to use this to prove what equipment was actually totaled for efficient replacement to help get the construction project back in motion.
To learn more about how drones can help you provide legal aerial photography documentation of assets and equipment in times of difficulty, such as flooding, contact us today at (214) 842-6000!
A sign of a thriving market is seeing cranes working on new construction projects everywhere. Throughout Dallas and most of Texas, if you look up, cranes are what you see. Anywhere from office buildings, retail, and multi family communities to new neighborhoods, developers across Texas are looking for new opportunities to invest in.
Any experienced developer knows how many studies must be completed and hoops have to be jumped through before making a purchase on a property for development. It is important to have up to date property details and surveyor data. Every property requires land moving to make it suitable for construction and can be a costly expenditure. If the land would require to much work, it could make or break the deal financially.
Traditional Way to Collect Data
Before buying a piece of property, you have to assess the costs that will be incurred before it can be developed or flipped. Every deal made has to be a financially viable opportunity. One of the biggest costs, that could make or break a deal, is land moving. The due diligence process can already be costly and there is often a good chance all the money spent in the process could go to waste if it is decided not to proceed with a purchase.
Traditionally, a developer would bring in a land surveyor to perform a detailed land study to gather information to estimate the costs associated with “prepping the land.” While a Land Survey is vital and even required to move forward with the construction and development of the property, there are other ways to more quickly and affordably collect preliminary data prior to making the purchase.
Drones are changing how many industries capture valuable data and information. With drones, we can fly an entire property capturing hundreds of GPS located direct overhead aerial images. We process these images into a highly accurate and detailed aerial map. As shown on the image to the left, we can consistently provide 3- 5cm of true ground level accuracy with pictometry and export a resolution of as good as 1/2″/ pixel of the image, allowing you to see every detail of the property. The DJI Matrice 210 with RTK triangulates its location to precisely capture each images location for precise map processing. This image can be very valuable both in the early stages of considering buying a property and being correlated down the road with the engineer certified land surveyor. The use of this data collected can save the survey team in the field time and you money. In the overlay here, you can see how much more accurate what we can process is in comparison to google maps.
DTM (Digital Terrain Model)
For developers, the real value is found in the Digital Terrain model. As pictured to the left, this export can give you a pretty accurate read on areas of a property that will be difficult to work with such as creeks, sloughs, ditches, and areas that are prone to retain water. Knowing the elevations and lay of the land give you the data you need to perform calculations and estimations on where the land needs work, quickly calculating how much the investment will require, and calculating what the return on investment could be. Aerial mapping can be surprisingly efficient and we can sufficiently map large properties to fit in your time constraints. Multiple exports are available to fit your capabilities from a .jpg to a geolocated image that can be plugged in to Google Earth and even Auto CAD.

We recently worked on a project in Houston, TX that presented a variety of challenges. We worked closely with a roofing company, legal team and engineering firm to assess a roofs condition for a law suite against the roofing company who performed the installation of the new roof system for our client, the property owner, back in 2016. We performed 3 thermal inspections at various times throughout the night. We also performed a physical inspection thoroughly walking the roof and the interior of the building studying where persistent leaks were occurring. The roofing company that was apart of the process performed 1 core sample on the roof identifying moisture is present. Outside of that, no other destructive testing methods were used.
This “case study” will review the suspicions and reason the inspection was requested, review the science of how the materials act and react with different climates and situations, understand the results and date we collected and discuss how we came to the conclusion we did and tell you a little bit about the equipment we used.
Roof Construction & Back Story
The roofs construction included a 60 mil TPO membrane, 1.5″ of ISO boards and a 2″ Gypsum Deck and is roughly 40,000 sq’. As we understand it, the client had paid for a Built Up roof system (like a cadillac) and the roofing company installed the TPO roof (like a Chevrolet) instead. They were to salvage and reuse the Gypsum deck that was not already saturated. The issue here is that they did not receive the roof they were promised and moisture was entrapped in the roof system upon installation rather than it being properly replaced. Anyone with common since knows that trapping moisture in a building only leads to more problems and head aches down the road…
Due to the TPO roofs components and reflective nature, the roof system will cool down much quicker than other types of roofs. This makes them very difficult to inspect. Even at a direct 90 degree angle where you should see the least amount of possible reflection, the roof system can still have reflective tendencies. Cloud cover during the day and at night affect the roofs ability to radiate, surrounding buildings will reflect temperatures off the roof, and even the wind can cause heat from surrounding areas to blow over the roof system causing false thermal anomalies to appear in the images. Capturing images at various times from different altitudes and angles allows us to collect various data to study and determine if what we are seeing is actually moisture. Of course, the only way to know for certain is to perform a moisture test with either a probe or core sample on suspected areas.
Results & Detailed Report
After thorough investigation and review of the various inspection photos and physical findings, we concluded that this roof system (the TPO and 1.5″ ISO Boards) was installed over an already wet Gypsum Deck from the previous roof system or there was a lot of rain during the installation of the new system. Gypsum is very susceptible to moisture as it tends to soak it up like a sponge. There were 2 leaks located from the inside of the building and are directly correlated in location with moisture found within the roof from the IR inspection. We were also unable to find any other punctures, tears or penetrations indicating that the majority of the identified moisture was in the roof prior to installation. Since the roof was fairly new and the ISO boards were not directly in contact with new water getting into the roof system from the surface, we suspect that we were unable to see the majority of the roofs moisture. Insulation helps to keep energy, both hot or cold, from escaping to the outside of the building. If the Gypsum deck is wet but the ISO boards are not, we will not see our typical IR patterns on the outside, making it difficult to identify how much of the Gypsum is saturated. We suspected moisture to be present in about 25.8% of the roof system and verified roughly about 8.44% total from the walk through.
Some of the patterns we identified were very similar in shape to some of the debris on the roof. The debris and low areas that are prone to ponding water indicate deterioration of the insulation within the roof and would be suspect of current or at least past moisture problems either way. If the ISO boards aren’t soaking up the moisture, when the roof system sweats the moisture on the inside, it can become trapped between the ISO boards and the TPO membrane and can cause these thermal patterns. Our other images did not reflect much change in pattern on other days.
To see all the details and study the report to understand our findings, here is a sample based on this particular project: Project Sample Report
We utilized the DJI Matrice 210RTK with the x4s for visible images and zenmuse xt 640R for the thermal scan. The combination of this equipment gives us adequate flight time, the resolution imaging we need to properly inspect and get the detail we need on a roof system, allow us to see visible and thermal images to understand what we are looking at from the outside in comparison to the thermal scan and help us maintain visual awareness of the drones relation to structures and other objects in the area while flying at night.

Drones can be beneficial for a variety of industries. There are only a few applications though where they can be invaluable in comparison to other resources available today, and curtain wall/ building envelope inspections is one. Rather than spending an incredible amount of time and money on lifts, scaffolds and hanging over the sides of buildings, we can use a drone to capture up close images of high rise buildings. Utilizing this resource is beneficial for the due diligence process when time is of the essence and when an engineering firm or property owner needs preliminary imaging and information about the condition of the exterior of a high rise building for maintenance concerns or remodeling projects.
We utilize a DJI Matrice 210RTK- D for our envelope inspections for a few reasons. This drone has redundant systems and a 360 degree obstacle avoidance system built into it to ensure safe flight operations within close proximity to large buildings and structures. These systems help with human error and un predictable winds to maintain stable and accurate flight to collect the necessary data and information. The RTK flight system allows for triangulation with multiple satellites and location systems to help with the location data and UAV communications with the pilot. We have an array of cameras to help capture what you need from a safe flying distance to include the x4s, x5s, Z30 for collecting visible imaging. We also are licensed and utilize the Zenmuse xt 640R for thermal inspections where applicable.
From this inspection, we identified multiple areas where the MP1 was weather and cracking, allowing water to get in to the expansion joints where it freezes, expands and causes chunks of the exterior of the building to break off and expose the rebar. If this problem is not corrected properly and efficiently, you will see long term negative effects on the condition of the building. What has gone from an inexpensive preventative maintenance item has become a costly problem to repair. Below are images collected from the problems we identified.

The demand for the use of drones with thermal cameras to inspect commercial roof systems is growing rapidly. If you are a company involved in the commercial roofing industry and do not have the use of drones incorporated in your practice somehow, you are missing out on a big opportunity. We used thermal imaging from a drone to help a property management company for an office building locate where 2 leaks were most likely coming from. We located 2 areas we suspected moisture intrusion and provided a full report to the roofing company for physical inspection and repairs. This process saved the roofer a lot of time and the property management company a lot of hassle as we were able to help get the problem corrected more quickly and efficiently.
Drones help to give you a close up direct overhead view of the problem at hand. As thermographers, we constantly deal with what we call heat reflections from other objects effecting our images. Capturing a direct overhead shot takes that element out of the equation and lets us get up close in comparison to the use of airplanes. We dont even need access to physically get on the roof, meaning the property management team doesn’t have to be on site at unusual hours.

The use of drones is expanding in many industries as technology only gets better by the year. For utilities companies and energy providers, we can provide thermal drone inspections, aerial mapping and imaging, and LIDAR services to help you complete a job more efficiently and effectively. Our team at Tarillo Vue operates legally under the guidelines and regulations set forth by the FAA and are fully insured. All of our pilots are certified UAV operators and where applicable, have at least a level 1 thermographers certification.
We utilize the DJI Matrice 210RTK- D (drone) paired with the Zenmuse XT 640 with Radiometry thermal camera and X4S 2omp camera. This combination gives us standard and thermal HD eyes in the sky from an extremely stable platform. This drone is designed to deter strong magnetic interference, making it much safer and easier to fly near high powered powerlines.
Drone Thermal Inspections
When we conduct an IR inspection, we are simply looking for hot spots on power line components. We often perform inspections on newly constructed, active and re- activated power grids. Some of the components and problems we can identify are:
Failing lightning Arrestors
Bad strands on cables
Poor ground or nuetrals
Bad insulators/ cutouts
In past inspections, we have located hot spots on insulators, cut out doors, lightning arrestor and possible loose connections. Once the hot spots are located, components are identified, load data and component ambient temperature data is collected, we provide a full detailed report on the hot spots located giving you the information needed to conduct a physical inspection to make repairs accordingly. The use of this process makes it easy to plan everything out, be prepared for what parts and components are needed, avoid power outages and down times, spending time locating where the failures took place and what else was affected. All the photos we capture are GPS located, making it easy to locate where in the field the problems exist and identify exactly where the problem is on the line.

Aerial Imaging and Mapping
The resolution and accuracy we can provide with drones to create aerial maps is like nothing else we have ever seen before. If we can coordinate with a land surveying crew to capture GCP’s (Ground Control Points), we can guarantee an accuracy of 3- 5cm. Once images are captured in the field and processing is complete, possible deliverable exports include:
2D Orthomosaic Model- We can provide high resolution exports ( as good as .4″/ pixel of the image). These are exportable in JPG or GeoTIFF formats.
Elevation Survey (as is with plants, vegetation, structures, etc.)- Exports available in GeoTIFF, JPG, Raw Elevation Values (DEM), Contour DXF (AutoCAD), Contour SHP (Shape File)
3D Model- Exported as an OBJ file, we can deliver a full 3D model of the field and what it looks like with trees, structures, etc.
Point Cloud- We can export .las and .xyz point clouds.
Exports without Plants, Vegetation, Strutures, etc.- These exports provide us with a true portrayal actual ground level elevations and studies. We can have shrubs, trees, tall grass, buildings and anything else in the way removed to put together an true ground level survey.
Using drones, we can capture a birds eye view of all the assets and equipment in the field for documentation and office use. These images are high resolution and help you know what you have in the field without having to drive out there or be onsite to properly communicate with your field crews.
LIDAR on Drones
We have the ability to utilize LIDAR technology on drones to more affordably build out accurate 3D models of power lines in relation to ground levels to calculate line sags. Having these 3D models would also be valuable for new construction planning.
We conducted a drone roof inspection on The Oasis Apartments in Denton, TX for Multi- Family Investments. Utilizing a DJI Matrice 210 RTK with an X4s and a Zenmuse XT 640 with Radiometry, we were able to capture images inspecting both the interior and exterior of the roof. This roof is a TPO flat roof system. With todays technology, we can perform more organized and detailed roof inspections, providing you with all the information you need to know to make an educated devision on whether the roof is a total (20% or more) loss or determine what repairs need to be made. The data we provide can be extremely valuable to property management companies, property owners, insurance companies, public adjusters, roofing companies and engineering firms.
When it comes to thermal imaging, you often have a short window around sun rise or sunset to capture the data while the roof temperatures are changing. Drones make this process much quicker, safer and easier. We can organize the information collected much more efficiently, capturing an overview of the roofs condition while having the ability to capture close up images of the issues located within the roof system. Every image is correlated with a gps location, giving us the tools to identify exactly where problems exist on large roof systems. We can process the images of an entire roof into a map to generate measurement tools.
How Can You Benefit?
Save time and money by locating where all the moisture exists on the inside of the roof system.
Provide your roofer or engineer with a preliminary detailed report putting them right on top of where the issues already exist rather than spending hours looking in areas that aren’t problematic.
Calculate a true 20% total loss.
Have online measurement tools at your disposal to determine the size of damaged areas and exact locations from other objects on the roof.
Use our detailed reports as hard evidence to help win insurance battles faster by proving internal conditions.
Compare hight resolution daylight and thermal images to examine the exterior of the roof in correlation with internal exceptions.
The use of thermal images can prove a roofs condition prior to a hail storm (must be completed before the storm hits) and its condition afterwards.
What We Deliver
Our deliverable on a project includes a full detailed inspection report, full size images for detailed review and processing, and the option for a processed aerial “map” map of the roof, giving us the ability to perform precise calculations to determine if a roof is a true 20% total loss or not.
