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 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.

What 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 option

The 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!

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.

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 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 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.
