ROOF INSPECTION

Have a roof inspection done today!A roof inspection is good to do every year.  A commercial roof is a very large expense.  If you wait until your roof leaks through the ceiling to start caring for your roof, you've waited far to long.  At Drone Infrared Imaging one of our specialties in roof inspections.  Roofs of all ages need to have inspections.  I don't know what it is about flat roofs but things happen up there.  Anything from people vandalizing to bullets puncturing the roof from people shooting in the air.  What goes up must come down.  Yes I have seen it.  Animals can cause havoc on a roof.  People storing things on the roof can also damage a roof.  And lastly one of the biggest causes of a commercial flat roof being damaged is neglect.

Core sample of a flat roof

One of the most important part of an inspection is to do a core sample to know what is going on.  The above pictures reveals a poured concrete deck with multiple layers of felt and tar.  It also have a modified bitumen cap sheet.  We know from this that a leak would take a lot of time to penetrate all the way through the concrete.  As a result, inspections for this type of roof should be performed often.  By that I mean once or twice a year.A roof inspection is not an expensive proposition.  They range anywhere from $450-$1200 per building.  They could cost a little more depending on the circumstances.  Or they could cost less depending on how many buildings.  At Drone Infrared Imaging we can also provide an aerial picture and or an infrared picture of you roof.  This would all depend on what service you would prefer for your roof.  Thanks for checking out my blog.  We look forward to hear from you.  Drone Infrared Imaging.

ROOF CONSULTANT

When should I hire a Roof Consultant?Never, if you want to make the mistake that so many others in your shoes have made.  Understanding your roof system and have a professional make some decisions regarding that roof can go a long way in saving you money in the end.  Also a lot of building owners, property managers, condominiums, apartments need the security of hiring a roof consultant.What would a Roof Consultant do for me?He should make a clear and concise assessment of your roof.  He should know every component of the roof system from the deck to the top layer of roofing.  There should be an explanation of  how he got to the decision of picking the roof system he chose.  Pictures are a must for explaining each item involved in the roof system.  We at Drone Infrared Imaging, use a drone with a HD Camera to allow us to capture pictures and video to put in our presentation.Specifications are  probably the most important piece to the puzzle because it keeps everyone on the same page.  How many times have we been in a position of making a decision based on three or four different types of roofing systems.  This leaves us guessing which roof system will be best for our situation and it leaves the door wide open for massive price differences.  If all contractors are bidding from the same specification then the price differences should be small.  Roofing contractors tend to give better pricing if they know they are bidding the same system and are bidding against other who are doing the same.The last piece is to decide on a roofing contractor to confirm their pricing and set up the project.  The consultant can also be involve with the entire roof project to make sure things are getting done correctly.  Aerial photography can be taken periodically to inform all involved where we are at in the progress of the roof project.  Video Overview of a Roof ProjectWhat about Roof Consultant pricing?There are many price points which can be used.  The consultant can just assess the roof system currently install to see if repair can be done which would be a low-cost item.  Or they can be involved in the whole roof replacement process from start to finish relieving the burden of others having to take large amounts of time and energy out of our busy schedules.  All price points will be available after an assessment of the project is done depending on how small or large the project is.
Aerial Photography

Aerial Photography

Aerial PhotographyAerial Photography in roofing can highlight any project from start to finish.  Any contractor can use these services.  Aerial Photography can be used as a safety check, project progress or project completion photographs.  This is a completed roof photograph with no editing, just a raw photograph shot by DJI Inspire 1 pro camera.  What is amazing is that during the time of the photograph it was abundantly windy yet the picture turned out clear.  These amazing machines can be used for so much and will continue to be used for so much more as we learn all of there capabilities.Aerial VideoOne of the most impressive features of a drone is the ability to capture 4k video.  What we are trying to achieve is a butter smooth video to be used on some type of promo website hopefully capturing the magnitude of this building Front of Building Video 1.  This building seems to go on forever, but with the help of a professional drone we can capture a new perspective or as one person on the ground said as he was watching me film on my Ipad, "The building doesn't look so big anymore".  The contractor who did the roof installation used these pictures to really impress the building owner.  This in turn caused the owner to use the photos in many different departments of their company.  In the end all we want is happy customers.

Commercial Real Estate Roof Inspection

Commercial real estate roof inspection with infrared will take the unknown out of the equation in purchasing a building.  With the new codes for roof insulation on a flat commercial industrial roof, commercial roofs have become a very expensive proposition.  As an owner, if you are purchasing a building, an infrared scan of the roof can reveal what current owners probably don't want you to know.  Moisture underneath a roof system will serve as a catalyst to deteriorate the roof system from the underside of the system.   What does this mean?  Replacing your roof could cost between $10-$20 per sq ft.  This needs to be negotiated before the sale of the building!The above infrared roof scan can reveal whether there is moisture trapped under the system.  Is the above infrared something that will make us fearful or something that will make us feel secure?  The answer is secure.  The above system has very little changes in temperature all the way across the roof system thus giving it an "A" rating.  There are no signs of moisture or leaks for that matter.Drone Infrared Imaging can give security knowing for sure the roof on your future facility is in good condition.  We can take the guess-work out of a roofing contractor taking core sample to see if moisture is found.  ONE other important point: Roof insulation can absorb a lot of water before it actually leaks into the building.  So just asking if there are any leaks is not a good determination that the roof is safe and sound.

DRONE INSPECTION

Drones are going to be used in many industries in the years to come, way more than what you think.Will drones be delivering packages?  I don't know.  Currently a drone in between .5 lb and 55 lbs cannot be flown if it is out of our line of sight.  You would be hard pressed to flight a drone two towns over and maintain line of sight.  Oh and by the way no help of anything to enhance vision can be used according to the FAA.  A drone inspection can reveal so much more information we could not see in the past.  Drone inspections can be performed on roofs, construction sites, water towers, electrical towers, stacks, walls, siding, water treatment, agriculture, condominiums, townhouses, factories, commercial buildings and all of these can have infrared imaging.

A drone inspection is done to discover and plan for the future.  At Drone Infrared Imaging, we can inspect whatever property, building, obstacle or object that you may need inspected.  Drone inspections are especially useful for bigger complexes but certainly not limited to them.
Infrared Roof Leak Detection

INFRARED LEAK DETECTION

Infrared leak detection is a smart way to see how your roof is doing, EVEN IF IT IS NOT LEAKING!  Owners, property managers, entrepreneurs and companies usually take the same approach, if my roof isn't leaking we are good.  Not smart.  The smart money is on having an infrared done today by Drone Infrared Imaging to see how your roof is doing.We are heading into the wintertime months, which are going to accentuate every roof leak, even the small ones.  What is going to happen is the small amount of water that is getting under the roof is going to freeze and blow your seams apart causing big leaks.  This doesn't have to happen.See complete report for this roof: Infrared Roof Report  The contractor installed 5 different types of roofing on this building on purpose to see how they would perform.
Infrared Leak Detection

The above picture taken from an infrared drone indicates a leak by a skylight.  The roof overall should cool down the same temperature at night, this small area by the skylight remained hotter than the rest of the roof.

Infrared leak detection is not just for roofsNote that leak detection does not have to be localized to just roofing.  It can be used on any surface that has radiant heat emitted from it.  Walls for instance is a good example.  Many times leaks are improperly diagnosed because the point of origin is not the point at which the moisture gets into the building.  The infrared drone can capture images and or video which take the guess-work out of it.

Infrared imaging on a rainy, windy daySo what does an infrared drone guy do on a rainy windy day... practice.  Happily Flir in conjunction with DJI has upgraded their camera and software to give so many more options.  All the colors and palettes become more vivid and dynamic.  You can even tell how hot your cup of coffee is if you have your drone fired up and running (no propellers) and facing yourself.  The Starbucks coffee was 140 degrees when I first set it on the desk.  Within the first 10 minutes it decreased 20 degrees.  Enough about coffee.Infrared Imaging    Infrared Imaging    Infrared Imaging    Infrared ImagingInfrared Drone UsesThe use of drones and infrared imaging are growing.  A lot of people don't even realize how useful it can be.  I recently had my DJI Inspire Pro with the XT Flir camera flying over a commercial building.  Now I didn't know were the leaks on the building were, but after careful examination I circled areas of concern on the infrared and presented this to the owner.  Surprise surprise the areas that I circled on the infrared turned out to be close to the leak areas on the building.  Now the owner is educated about his roof leaks on his building and a roofing contractor can come out and accurately repair the roof.Roof InfraredHvac contractors can use infrared to see how hot the units are running and believe me some run very hot compared to others (see picture above, two units running hotter).Electric companies can inspect transformers and any other part of the electrical systems to find out what is operating inefficiently.  Any type of piping that runs on the outside of a building can be inspected.Cellular towers can be inspected.Search and rescue, especially at night reveal vivid pictures of human being trying to hide or run from something.The energy efficiency of any building can be determined.
Commercial roofs need infrared imaging

DRONE INFRARED IMAGING

Drones provide quick infrared resultsThere are many ways to evaluate a commercial building.  One way is to do a visual inspection by walking the entire roof.  Another is taking core samples of various areas of the roof.  Still another is through aerial photography.  If a professional roofer is able to look at an aerial detailed picture, many areas diagnosis can be given just from the picture alone.  Probably the most promising is to do an infrared scan of the roof.  Some infrared cameras even allow you to take video.  Isn't technology wonderful.  After getting to the facility and mapping out a plan, making sure it is safe to fly, it is only a matter of 15 minutes and the infrared drone can be up and flying over the facility.  There is so much information that can be gained from the infrared pictures and video.Discover roof leaks, heat duct leaks and energy deficienciesIt is important to note, not all roof types can have an infrared scan.  If the roof is scanned for leaks, roof leaks will be obvious.  Roof leaks will allow water to saturate into the insulation causing those areas to be hotter as emissivity is happening.  Emissivity is the ability of a surface like a roof to emit radiate energy.  Roofs during the warming of the sun can cause some roofs to get to 180 degrees.  If a roof is dry and free of leaks, emissivity will happen consistently across the roof.  Wet insulation under the roof will cause the radiant heat of the roof to stay hot.Some HVAC units are equipped with side mount discharge, meaning the duct comes out of the side of the unit.  These ducts can also be tested for leaks through the infrared scan.Lastly the roof can be scanned to discover potential energy deficiencies.  For example, over time the roof insulation shrinks causing gaps under the roof membrane.  These areas can be detected through an infrared scan.  If it is cold outside and the building is being heated then the lines along the edges of the insulation will test hotter because the hot air is trying to escape.To learn more about emissivity go to: https://www.youtube.com/watch?v=75PmF7KLf4A
