ROOF SYSTEM X-RAY

Roof System x-ray (sort of read on)A roof system x-ray or better known as an infrared of your roof system, performed with a drone, can be both cost-effective and eye-opening.  The featured picture is an infrared of the below building.  Drone Infrared Imaging flew about 80' off the ground to capture the below image.  The pvc roof system has seen its better days.  The roof is now dull and dingy.  The black stained areas usually have to do with the lack of drainage on the system.  A roof that has poor drainage does not mean those areas are leaking.  In this example, it is revealed that it is opposite.roof system x-rayWhat would a roof consultant say?A roof consultant would probably recommend a complete tear off for this roof system.  Good plan if the owner of the building could afford it.  The infrared drone is just reading the moisture of the layer of insulation directly under the roof system.  It can't read the other layer which is under the initial roof system and over the deck.  The only way to know the moisture content in that layer would be to investigate leaks by doing a series of core samples.Infrared Scan helps to provide economical roof system optionThe roofing contractor removed the top layer of roofing.  The infrared helped make this decision.  The moisture did not penetrate the initial layer of insulation over the deck so they could leave that roof in place.  This made it very affordable and something that the owner was willing to do.  The requirements for roof insulation are very high.  Roof insulation is now the highest component of the roof system.  A recovery board was installed instead of all the different layers of insulation which saved money.  There was a labor saving by not tearing off the bottom roof.  As a result, a building owner was happy!
Thermoplastic Roof

THERMOPLASTIC ROOFS, BENEFIT IN THE MIDWEST?

White thermoplastic roofs are coolThe 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 summerWhether 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 winterThe 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 benefitUltraviolet 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.

FLAT ROOFS LEAK. TRUE?

What's the real reason flat roofs leak?If you talk to almost any facility manager they would tell you all flat roofs leak.  In this article we are going to look at the reasons why a commercial roof would leak.  Before we get started, please note that this is not about one particular roof or owner.  This is about flat roofs in general.  Doing an infrared scan of any roof is a good starting point towards taking care of any roofing system.  With the latest technology, an infrared scan can be performed through drone technology.  Most roofs can be scanned with several infrared photographs.Roofing mistake #1Owners, property managers, leasing companies, and retailers often make one mistake which is waiting until their roofs leak to take care of the problem.  Commercial roofs are a major investment and they need to be taken care of similar to your car.  Would anyone wait for their car to stop before they maintain the vehicle?  Never changing the oil in the car will cause the car to fail way before its time.  It is the same with any roofing system.  If you don't maintain the roof it will fail way before it's time.  Manufacturers of roofing material all want their roofs to be maintained.  Why because they want to know how their roofing material is performing.  There is also some things that are not covered in the warranty that need continued attention.  All sealants such as pourable sealant and caulking are not covered under the warranty agreement.  So if the pitch pocket (where wires and lines come through) dries out and or shrinks and the roof leaks, this makes one think that the roof system is failing.  Not true.  Please maintain your roof at least once a year if not twice a year, it will save you money in the long run.Roofing mistake #2Realizing that the above is the most important for any type of roofing system whether it is new or old, the next thing that needs to be done is know who is going onto your roof.  I can't tell you the number of times I have been on a roof that has a leak that was caused by other contractors.  This is usually the scenario.  A contractor goes onto the roof, works on a piece of equipment, finds out he needs to replace something and drops the part or tool on the roof causing a puncture.  Sometimes these can be very small and take a good while to show up as a roof leak and sometimes they can leak immediately.  Oil from condenser unit can cause havoc on a lot of roof system especially EPDM (rubber roof).  They will begin deteriorating shortly after the oil is spilled.  The bottom line is make sure you trust the people who are going onto your roof.

Roofing mistake #3Putting additional pieces of equipment through your roof needs to have a professional roofing contractor install the flashing.  What you don't want is for a subcontractor to install the equipment and install roofing cement to the bottom flange.  This is about a one year fix and sometimes it is less depending on the movement of the equipment as it is operating.  A professional install of the flashing takes time and will cost some money, but it is well worth it in the end.  The most vulnerable area of your roof is the penetrations through the roof, if they are done right, there is a better chance to extend the life of your roof.

THE USE OF DRONES IN AGRICULTURE

Agriculture and the use of Drones

On a large farm, the inspection of crops can be an overwhelming task.  How can a farmer other than walking the fields or renting a helicopter ever be able to tell how his crops are doing.  The land especially in Illinois is very flat with no rolling hills to climb onto to have a look to see how the crops are preforming.  Crops are a farmers livelihood, so if they are not producing there is money that is thrown away.  Early detection is the key.  If there are large acres that are not growing or growing slower than others, the areas can be pinpointed and inspected to figure out what the best course of action should be.  Agriculture is using technology more and more every day.

Should I take an infrared, video or take a topography map with a drone?

A determination needs to be decided ahead of time.  What is needed to help your crop (your bottom line).  I was a farmer for the first 18 years of my life.  My first thought when I heard of using drones for crop inspection was, "Why would you ever need that?".  After hearing all the technology that could help produce more crops, my tune soon changed.  Taking pictures or video can tell bare areas or crops that are not growing at the same rate of speed as the rest of the crop.  Taking infrared can tell the moisture content of the ground to see if that is effecting the growth.  Taking a topographic map of the land can also pinpoint areas of concern.

PROPERTY MANAGERS NEED TO KNOW HOW THEIR ROOFS ARE PERFORMING

ROOFS LEAK! When do people usually take care of their roofs... when they leak!  There is another alternative.  Taking care of roof begins with a good inspection to access to see if there is any damage.  Buildings that are over two stories tend to get neglected the most.  Every storm has the potential to blow off one shingle, chimney cap, ridge cap or exhaust vent.  Would you want to know if these are missing and schedule to fix them before it leaked into the plywood, then onto the insulation and finally through the drywall.  I believe the answer would be... YES.PROPERTY MANAGER INSIGHT Commercial flat roofs can experience the same kinds of damage.  Actually flat roofs are more susceptible to larger roof blow offs that are shingle roofs.  Inspections are a good way to know for sure that your roof is safe and secure.  At Drone Infrared Imaging, we can put a drone in air and quickly assess damages.  Property managers especially need to be in the know.  Dealing with complains all day is exhausting for property managers.  Wouldn't it be great to know your roof is safe and secure thus eliminating that headache.DRONE INSPECTION We recommend have properties inspected at least 2-4 times a year with possible drone inspection right after a severe storm.  The drone can take pictures of every aspect of the building, not just the roof.  Drones have the ability to capture pictures like a 3-D.  So the perspective is different from a straight up google earth picture (although they are starting to use some 3-D).  To be able to see if there is soffit or fascia torn off or gutters missing or plugged can save money in the long run.  How can it save you money?  By being able to fix the issues before it causes inside damage. Inside damage is costly to fix, so anytime this can be avoided, it will be beneficial for all involved.

THE NEW SUPERINTENDENT IN THE SKY

Drones have many uses and one of them is to document the progress of a construction site.  Snapshots or video can be taken for many purposes.  One of those purposes could be to practice safety on the job site another could be for training of employees still another could be to communicate to the client in an impressive way.  Drone footage gives a wide perspective that can capture the whole project in one photo.  Another exciting way is to video 360 degrees all the way around the site.
