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 Project What 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 Photography Aerial 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 Video One 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.
Drone Inspection

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 roofs Note 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

Infrared imaging on a rainy, windy day So 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 Imaging Infrared Drone Uses The 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 Infrared Hvac 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.

PIC AND AN INFRARED DRONE PIC used to stand for Picture.  No longer, the FAA has taken it for there very own.  It stands for Pilot in Command.  The FAA wants every person that is going to fly commercially to be trained.  Flying without an Airman Certificate is Illegal.  That's why everyone at Drone Infrared Imaging must pass the Aeronautical Knowledge Test before they fly.  If nothing else its gets you to think about more than just picking up a controller and taking off.  There is a lot to think about, like the weather, obstacles, wind current around buildings, aircraft, line of sight, visual observer, magnetic fields, down drafts, updrafts and the like.  Our ultimate goal is to be safe.  An infrared drone is a very expensive proposition and believe me we don't want anything to happen to it. Infrared Drone               Infrared Drone Airspace Yes we have to share airspace.  The above images were taken in Class D airspace.  Because the airport has a Control Tower, they had to be contacted so we could get permission to fly.  It is a little bit of a hassle to actually speak to the tower, however the overall process was quite painless.  They gave permission and we were able to fly. https://www.droneinfraredimaging.com/infrared-scans/
Roof Safety

Roof Safety

BASIC PRACTICAL RULES FOR ROOF SAFETY If it looks unsafe it probably is unsafe.  I don't know how many times we have been on job sites to see obvious glaring violations.  The worst is when the owner comes on the roof and they can tell the violations without knowing the violations.  Point being make sure your roof projects look safe!  One final note here, if your job site looks crappy even though you are safe, it gives the appearance of being unsafe.  Let's keep job sites cleaned up. Roof safety should be taught and caught.  Don't get caught in the trap of, well we didn't have many accidents last year so let's skimp on safety this year.  It always works out bad.  Having Drone Infrared Imaging capture pictures and video from your projects to use in the roof safety class room is priceless.  Not only to point out the things that need correcting but hopefully to point out perfectly staged job sites. When safety equipment looks old, it looks unsafe.  Yes I know some of us are conservative and we like to use things until it dies but let's try to stay clear of doing that regarding safety. AN OUNCE OF PREVENTION.. An ounce of prevention is worth a pound of cure.  A little precaution before a crisis occurs is preferable to a lot of fixing up afterward.  Roof safety can prevent a lot of personal injuries.  It can also prevent the ultimate tragedy which is loss of life.  Workman's compensation claims can cost a tremendous amount of money and can drag on for years.  If there is time given in the class room with pictures from Drone Infrared Imaging, that's a great start.  After that having tool box talks with your guys on a weekly basis.  One more thing, your foreman should be very safety conscious and as a result should hold all the guys under his care to a high standard of safety. BE SAFE!

ROOF INFRARED OR LOTS OF COOL COLORS

Roof Infrared Interpretation Yes the roof above does have leak issues. The roof is a BUR roof and the gravel is spread evenly across the roof (meaning the roof should have cooled off at the same temperature which it did not). Can you just look at a roof infrared scan and tell what is going on?  Are all the red areas on the scan a roof leak?  Are there some roofs that can't be scanned?  These questions will be answered in this blog post. Question #1.  First off, there are so many different roof membranes producing so many levels of radiant heat that a hot spot could mean many things.  For example a large area of ponding water could cause the membrane to be cooler than it should be.  Another example could be repairs that are black in color could produce hotter than usual temperatures.  This would lead one to believe that the roof has leaks in all of those areas.  This is why it is very important to have someone like Drone Infrared Imaging with 30 years of commercial roofing experience interpreting what the infrared scan is revealing. Question #2.  There are different palettes of color that Flir Camera can be set at, so saying that all the spots that are red are leaks won't work.  Even if it is set at a rainbow setting, red spots could come from many different avenues.  HVAC units (see picture) in the summer operate very hot and can cause the membrane to stay warm longer.  Different membranes DJI_0049used on the same roof systems for repairs.  Even tar that has bled through the gravel of a BUR roof system can cause hot spot.  My point here is you need to know your membranes and the ambient heat that they produce. Question #3.  For the last question the answer is yes.  One example is a EPDM Ballasted Roof.  The ballast stays at a consistent temperature masking the real temperature of the EPDM under the ballast.    
Commercial roofs need infrared imaging

DRONE INFRARED IMAGING

Drones provide quick infrared results There 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 deficiencies It 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.

Thermoplastic Roof

THERMOPLASTIC ROOFS, BENEFIT IN THE MIDWEST?

White thermoplastic roofs are cool The most common thermoplastic roofs are PVC (polyvinyl chloride) and TPO (Thermoplastic Olefin).  Both of these materials will prove to be cooler roof systems than most materials out there.  On a 90 degree day, an EPDM roof can get upwards of 170 degrees.  On a 90 degree day, thermoplastic roofs will be at a temperature of 110 degrees (approx.).  This is a significant difference in temperature.  Most consultants would argue that the temperature doesn't matter in the Midwest because they want the warmth in the winter.  I will tell you the biggest benefit in the last paragraph. Thermoplastic roofs in the summer Whether you are in the Midwest or not having a cool roof allows buildings to stay cooler thus reducing the cost of cooling buildings.  The other thing it does is allow HVAC units to operate more efficiently through reduced heat around the unit.  Both of these factors contribute to energy saving costs in the summertime months.  In future posts, I will have infrared shot via a drone to prove my points. Thermoplastic roofs in the winter The effects of the sun is significantly less in the wintertime because the sun is no longer high in the sky or directly overhead.  The absorption of the suns rays is not as strong as the dead of summer causing the black roof materials to reach temperatures that are less than if the sun would be directly overhead.  Don't get me wrong, is it beneficial to have a roof that is warm in the winter on a sunny day, YES.  The effects however are not as significant as the summertime cooling.  Is the energy savings more significant in the south, YES. Thermoplastic roofs biggest benefit Ultraviolet rays are probably one of the most damaging factors to any roof system.  Roof materials deteriorate because they dry out and crack or shrink.  Anything that can be done to avoid this process would be beneficial the roof system.  Thermoplastic roof can have a .070 - .085 reflection of the sun.  Thermoplastic white products are reflecting 70-85% of the suns rays back into the atmosphere as opposed to absorbing them and drying out the product.  So whether you are in the Midwest or the deep South, this benefit will always remain.
