Metal Roof leak repairs

We have been using Turbo Poly Seal on all our Metal Roof Repairs. The hardest part always is to remove all the junk people have used trying to repair leaks. From silicone caulk to adhesive tapes to tar. It is our experience that metal roof seams are big issues and a battle for owners to keep it from leaking hence all the repairs. When we started using Turbo Poly Seal we were elated with results on how much time and money we saved. In many instances, we covered large rusted holes with great success.

The standing seams in metal roofs cause many problems when skylights or airconditioner curbs are installed. When the standing seams buts up to the curb wall, it causes water to pool. This creates a problem over time. To combat water collecting between the standing seams above a skylight or Airconditioner unit, we cut a section away of the seam to allow the roof to be flat around the curb so water can flow around the curb. To seal the cutout metal seams, we use Turbo Poly Seal.

The following images will give a detailed explanation of standing seam issues against curb flashings of skylights and air conditioners.

The arrow points to the rusted area and a hole in the metal roof due to standing water. This problem happens all the time when standing seams butts up against a curb causing water to collect. See how we went about it to repair it with Turbo Poly Seal.

First, take an angle grinder with steel brush attached and clean the surface from rust. Remove all old caulking and tar. Try to remove as much rust as possible.

After cleaning and preparing the surface take a brush and paint a coat of Turbo Poly Seal covering the rusted areas. Make sure to cover the fasteners and extend over the seam panels.

After covering the surface, install a Polyester Fleece over the entire coated surface. Smoothe the Fleece out with your fingers to remove any air pockets.

After leveling the Polyester Fleece, it is time to add a final coat of sealant. Take the can and pour the content out over the fleece.

Take a disposable brush and spread the sealant evenly over the Polyester fleece.

The final result should look like this. There is no need to install a polyester fleece over all the areas. If the metal surface is still good, then a coat of the Turbo Poly Seal will be good enough.

    1. Sorry, we do not sell in Canada yet. We still have to get approved by Customs.
      Yes, Turbo Poly Seal performs well in cold climates

  1. I live in the American Southwest, El Paso, Texas, how will this product hold up to the scorching heat of the Desert? If I can get five years between resealing of the roof fixtures and skylights I’ll be happy.

    1. Hi
      After applying the Turbo Poly Seal I recommend you coat it with Silver coating.
      That way you are sure that it is protected against ultraviolet rays.

        1. The silver coating is Aluminum Asphalt that can be purchased at Home Depot or any roofing supply house.

    2. Hi John. You should get 5 years easy. What I recommend in severe ultraviolet exposures is to paint the Turbo Poly seal with silver coating or any other oil-based paint. But, before painting it, paint an extra coat and wait a day or two before painting it with protective paint.

  2. how many square feet does 1 gallon cover?
    can this be used directly on top of a concrete chimney crown? what surface prep is required?

    1. Yes, it is perfect to apply it directly to any surface accept EPDM rubber. It works perfect on cement surfaces like chimney caps. There is no prep necessary.

      1. can you give me an examples of epdm rubber? is rubberized wet patch epdm? are rubber boots on vent pipes epdm? thanks

        1. EPDM is a black synthetic rubber that is the same they use for innertubes on car tires. I used the Turbo Poly Seal over a roof boot that is made from EPDM but made the transition from the pipe to the roof itself or the flashing.

    1. Not at this present time. We still have to register with customs. I don’t know of a similar product that can perform like Turbo Poly Seal.

  3. Bill Hallbauer

    do you have a retail store in your plant that I could visit to pick up my items and chat to be sure I understand how to successfully use your product?

  4. Can I use a product called Permakote (Nationwide Coating) as a top coat for the roof after I have installed Poly Turbo Seal where needed? It is a white roof coating used a lot here in Florida. The metal roof has had a few bad patch jobs and has a few leaks. Just bought the building so I want to start on the roof first.

    1. It is always to prepare the surface. Rust is like dirt. The Turbo Poly Seal will bond to the rust but the rust will flake away eventually.
      Rust is duo to Oxygen and moist. So anytime you cost metal with any type of coating, it is likely to prevent rust. In this case, yes, Turbo Poly Seal will prevent rust.

  5. What is the application temperature range?
    I have a metal roof and not sure if it would be too hot to apply Turbo Seal during the afternoon, if that is an issue.
    Thank you

    1. You can apply it at any temperature that you can work in.
      I have not seen or heard of any problems as far as temperatures.

  6. Can i spray paint turbo poly or just paint it.
    What type of paint do i have to us. You still do not sell in Canada.
    I want to fix a metal roof , which product is better. Turbo or the super silicon .
    Thanks Ewen

    1. Hi Greg. We don’t sell in 5 gal pails. The price would be the same whether you get it in Gallons or 5 gal pails. We found that it is best to use Turbo Poly Seal from gallons instead from 5 gal pails. The reason is once the container is opened, you are forced to use it it up what’s in the container. There is but a few days shelf life after opening the container. So using 1 gallon at a time allows you to pace the project better.

  7. Hi, I have a metal roof with a pitch to a flat metal roof with cracks where I had rolled out the silver coating over old tar repairs. Can I use the turbo poly seal right on top of the old repairs, or should I get down to the metal and wire brush clean before use?

  8. Hi, after doing a repair with the poly turbo seal on a flat metal roof, will you recommend using fibered aluminum coating or non-fibered aluminum coating? Any benefit of using one or the other? I am in South Florida where temperature are very hot and I believe the fibered have less elasticity on temperature changes,but definitely will like your opinion on this.

  9. Hi!
    On September 13th, in replying to a comment, you mentioned “… once the container is opened, you are forced to use up what’s in the container. There is but a few days shelf life after opening the container. ”
    I just received the turbo poly seal kit with two 29 oz cans. There is no mention of limited shelflife after opening a container; the only thing the can mentions, is to
    ” tightly seal all partially used containers.”
    Aside from closing the cans immediately after using, what things can be done to maximize the shelf life of containers that have been already been opened once? By “a few days” I’m guessing you were saying that once a can is opened, it must be used within three days. Is that a fair assumption?
    What is the shelf life on unopened/unused containers of Turbo Poly Seal?
    Thank you.

    1. Hi Michael
      I’ll try to explain it better this time. Like any paint, Turbo Poly Seal is a combination of urethane and bituminous resins. Urethane cures when in contact with moisture. You will notice that most of the time the cans are overfilled, almost to the brim. The reason is to have as little air in the can when shipped to provide a longer shelf life. When you close the lid after using some of the content, as in any paint, you are trapping more air and moist in the can. This will cure a layer of the content in the can, but the layer will become the seal between the trapped air and the Turbo Poly Seal. I have used Turbo Poly Seal a month after opening the can but had to remove that fleece that forms on the top.
      There is no telling how long a shelf life you can expect. Sometimes the air is more humid and some times less. The reason I said to use all of the product in the can once opened, is to avoid people complaining. It is impossible to expect everyone to use common sense, some just don’t have it. Common sense comes with experience in a certain field.
      I really appreciate you bringing attention to this, I’ll make sure the labels will instructions include this situation as well.

      1. Thank you for your excellent explanation Naasfer!
        My favorite wood treatment — Minwax Helmsman Spar Urethane — also forms a hard cured layer on top in between uses. I now keep it in a glass jar to keep a better airtight seal. I don’t mind removing the film at each new use of the urethane — I always considered it part of the deal. I would not complain about something like that and it’s just as well that every DIYer knows what to expect and the many possible variables that come into play. It’s always great, and a real pleasure, to be enlightened by a true expert in any particular field. Thanks again!!

        1. Thanks for the compliment. Sometimes I am so tired, that I don’t spend enough time to explain things, but you are an encouragement to me

    2. Hi Michael
      I am reading through the post this morning and noticed that I have never answered your questions. Sorry about that.
      Turbo Poly Seal is a combination of Urethane and Bituminous resins. Bitumen takes time to dry because of the petroleum in it has to evaporate. On the other hand Urethane cures because of humidity. When it comes in contact with moist then it starts curing. That is why when we fill the containers is to leave as little air as possible in it to limit the amount of moist trapped in the can at the time of shipping. Once you open the can and use part of the material, you then will trap air in the can after closing it. This happens with paints, urethane, and other paint products you buy at Home Depot or other stores.

  10. How long is the expected out door life on a repair on a chimney flashing repair, untill you need to add another application of turbo seal? Also how big of a gap would you recommend that turbo seal can seal over properly?

    1. Life expectancy varies from place to place. But I think between 10 and 15 years.
      To get better results, I normally fill the gaps with a urethane caulking. But I have made transitions over 2 inc gaps already.

  11. Once turbo seal is applied and has dried. what are the steps and procedures if a repair needs to be made on the flashing etc, how is turbo poly seal removed?

    1. I hope you never have to remove Turbo Poly Seal. It sticks pretty well to metal and everything else. Several times I had to throw away the paint mixer that I used to stirr up a 5 gal bucket after it dried up. Lately, I clean the blades very well so the Turbo poly seal would not harden on it.
      I don’t know the answer to that.

  12. I have a “lean to” carport that was not flashed but was “sealed” with silicone (something called ‘through the roof’, I believe). I use the term “sealed” very loosely because it leaks like a sieve. Should I remove the old silicone before applying the Poly Seal?

    1. Hey Bob
      Yes, you have to remove the silicone. Turbo Poly Seal will not adhere to silicone. The easiest way to go about it is to use an angle grinder with a hardwire bristle cup and grind the silicone off.
      Preparation is the key to ensure a leak-proof transition. Make sure to use either lacquer thinners or acetone that you can buy at Home Depot to remove the thin film left behind from the silicone. Use a rag and thinners and scrub it hard to get it clean.
      I am sorry that you have to do this over again.
      Good Luck

  13. One more question Naasfer… I have about 25 linear feet of seam to cover. Will the two quart kit be enough to complete that?

    1. Yes, it should be enough. The Turbo Poly Seal Kit comes with a 25 roll of fleece. What I suggest is to cut the fleece in half lengthwise. That way you will have enough fleece to do the job. As long as there is about an inch of fleece on either side of the seam

  14. Hello sir, greetings from Northern Idaho! I am excited to use your product and most all questions have been answered here and on your great YouTube videos. It is an early, bitter cold winter here so far and just bought a home with a metal roof leak. I understand clearly all the prep work and application of Turbo. All I want to know is can I apply this product in below freezing temperatures and it will cure or dry still?

    1. Hi Ryan
      Congratulations on the purchase of your new home. I have applied Turbo Poly Seal at temperatures around 20 degrees Fahrenheit and had no problem with it. Yes, it will cure because of humidity. Urethane cures fast when it comes in contact with moist.
      Also, it can rain 20 after applying the sealant and the rain will not harm it.

  15. Hello,
    I will be using the turbo poly seal to repair a cement chimney crown and the flashing on my brick chimney. I will also be treating the brick with a sealer(Seal Krete) . Should I apply the turbo poly seal before or after sealing the brick or does it not matter?

    1. Hi Jared
      Thanks for all the images you shared about the chimney. After reviewing the images, I concluded that it was not necessary to use any sealant on the face of the chimney. Turbo Poly seal is the right thing to use for the chimney cap and the flashing.
      Send me pics after you did the chimney please.

  16. It says this product “should last 10-15 years depending on thickness of application” my first question involves uv exposure, is this 10-15 years when coated with a uv protector like karnak silver, or is that 10-15 years with nothing covering the turbo poly seal? Also if we, as a company are going to charge a company or homeowner to apply your product they are going to want to know whats the warranty? do you have any guarantees/warranty’s on your product

    1. Hi Matt
      Unlike the products that you see on the shelf of Home depot like caulking, which gives a 50-year life guarantee Bergstrom Industries does not provide any guarantees. There are too many variations to be able to do so. The rule of thumb is, the better the preparation, the longer it will last. The number that I give “10 – 15 years” is with protection. But in reality, if you protect anything from UV’s, it should last indefinitely. Ultraviolet rays are what degrade most products and life.

  17. i’m reusing a steel roof on a metal carport frame and now my hole spacing is off can i patch the old screw holes with this product or do you know how i should go about this? would it be best to fill in the old holes with panhead screws first or can this handle that kind of void as is? also how long do you estimate it will last?

  18. Question : Will this product repair roof leaks on steel shipping containers? Do you have any how to videos for this type of repair?
