Multiple issues here. 1) Never mentions how old the acrylic roof is. Acrylic coatings tend to lose 1-2 mils of thickness per year due to weathering which is why most manufacturers offering 10 years or more for warranty purposes require at least 2 coats. Better products with higher acrylic solids perform better and offer more flexibility and this coating from visual observations doesn't appear to have had such high solid concentrations. This roof appears to be at least 15 years old or more given how brittle the coating was, but he doesn't mention the age of the coating once. 2) Obvious to anyone who has been on hundreds of metal roofs that were coated with either acrylic or silicone, this roof was prepared poorly for the coating application. As with any paint or coating, preparation is everything if you want it to stick. He scrapes and wire brushes the metal roof and never bothers to clean the dust off or wipe the area he is working on before applying the product. So now a majority of his wonderful repair and product is adhered to dust on the metal panel area from wire brushing. 3) Metal roofs tend to have a lot of expansion and contraction, so as the original coating becomes more brittle there will obviously be cracks and fissures forming on the coating surface. 4) He runs panhead fasteners into the pan of the panel, not the best place for fasteners without an EPDM grommet on the fastener. Given the force he applied while driving the fasteners, my guess would be all the fasteners he installed were overdriven and will eventually begin to back out due to expansion, contraction and being overdriven. 5) He has applied his product which is relatively thick and has basically created a coating seam that is bucking water on the uphill side of the repair. Constant rains will eventually work its way under the repair given the area was prepared so poorly over time creating the same issues he is highlighting. 6) Did he bother to check if the rusted fasteners utilized were even compatible with the metal panel. Often times, contractors fail to realize some fasteners they use during repairs are not compatible with certain metals and this accelerates rusting issues between the fastener and the panel. The entire thought process that coatings are bad for metal roofs when in fact you are applying a coating yourself is ridiculous at best. As someone who has served as expert witness in multiple litigation cases on issues revolving around roof system installations, I can state I have seen extremely good coating applications and have in fact represented some in court that were not so good. A majority of the issues revolved around poor preparation with maybe 1-2% of my investigations involving around issues with the product itself. With any coatings, choosing the right coating and thorough preparation of the substrate either provides a long term solution or a short term nightmare. Bottom line, do your homework and understand the most expensive coating isn't always the best. All in all, if this was meant as a positive promotion for their product, it was done poorly at best.

Is silicone roof coating good for tropical zone?

Not a fan of elastomerics but for some roofs that don't really need to extend their service life i guess it is an OK fix. Our roofing company has used pretty much everything out there over the last 25 years. We use only one products after 8 years of success and not callbacks. There is a Liquid butyl rubber made by epdmcoatings. What we like about it is that it does not need a primer for any of the roof types we have applied it over that goes for metal, BUR, epdm, foam but NOT silicone. also it is a one coat application so we close much more business with this product because we come in as the lowest bid! It is a solvent product so primarily the reason it last all the years. Cheers

Any advice for removing rust on large scale for a big roof like in your video? I saw people use acids

Great video..one question, on an R-panel roof if it looks somewhat bend in or stepped on hard..like someone stepped on it very hard and now it looks like bend downwards and to the sides where it was stepped on....will this case the R-panel to leak?

That seal will last 3 years tops, if that. Not to mention it was applied over an apparent wet and very cold surface which means adhesion is minimum. This will dry, crack and peel very fast. Also, the black color will take a beating from UV rays that will further accelerate deterioration. I'd love to see the state of this patch currently as this video is now 3 years old.

I have tested both and have used both products extensively. Super Silicone Seal is more fluid and will cause runs easily if the roof is slanted making it harder for a clean job whereas Turbo Poly Seal is leas liquidy. Turbo Poly Seal gives you less linear feet per gallon. I really can't say which one is better. f you use Super Silicone Seal with the fleece in harsh Florida sun will last longer and you don't need to protect it against UV's.Turbo Poly Seal is nice for difficult areas and vertical surfaces as in flashing. Turbo Poly Seal is also much tougher. Honestly, I really don't know which one is better. Thanks for your comment. You are a good observer.

Our 30 year old ministorage has 30k sq ft of 29ga galv or galvalum on 5 of 6 buildings. Similar product as your video but never painted. Purlins are 1x3 wood spaced too wide at 36"-42" on factory wood trusses 3/12 slope. Concrete block sidewalls. New gutters and downspouts. In our 3 years have learned that NOBODY goes on the roof except a personally trained worker. Fortunately we identified dents which allowed gaps in the overlap seams (from 30 years of untrained roof-walkers) and have sucked them together with rubber-grommeted screws on top of the metal profiles. Replaced probably 25% of the suspect screws with larger diameter (75% yet to go) Appears leak problems are NOT accelerating, original fastenings mostly without rust stain (thanks to galvalum corrosion protection & rubber isolation washers). We've made significant gains against the very few customer complaints of water. Was a risky investment! BUT the facility is below road-level such that the roofs present a poor image of our business and brand. Multicolor stains over white oxidized alum as you would expect. Unthinking, I thot to paint to achieve unform color, prhps white for heat control. But I know it will get dirty. THANKS for the headsup about coating. But what shall I do for COSMETIC? And how to invest in a long-life impermeable roof? I'm thinking to add z-metal purlins on top of existing roof, one above each 1x3, plus one between, then a new powder coated roof over top. This way 190 tenants aren't exposed during the project. And prhps we insulate the space between old and new roof. How can I reach you as a consultant?

Aluminum roof coatings is all i use. It doesn't have the cracking problem that acrylic and elastomeric coatings do

Preparation is essential and proper application is important. However, using an acrylic elastomeric that doesn't lose key characteristics, like essential flexibility (elongation), is key to a superior roof coating. Most roof coatings on the market will use inexpensive plasticizers (for flexibility), which leech out, and cause eventual cracking and/or flaking. Same thing happens with asphaltic based products (i..e aluminum asphalt), as their oils will leech out of their coating. Acrymax's acrylic elastomeric won't lose their flexibility as it is built into the backbone of the very polymer (of their resin). This allows Acrymax coated roofs to have their life extended almost indefinitely with simple periodic recoats (at 5, 10, 15, or even 20 year intervals). Recoats simply maintain mil thickness. The thicker, the more robust, the longer before a recoat. See this video link, highlighting a college's roofs, done with Acrymax nearly 40 years ago and still going strong today: kzread.info/dash/bejne/g2ahmtSBcqy7hso.html

Acrylic coatings are great for metal roofs. Like you mentioned in your videos, it's all about preparation. They obviously didn't prep this one. In California some contractors use a seam tape that has a peel and stick backing and polyester surface. Once that's installed over seams and voids we apply acrylic gel and then after it's cured we apply lMetacrylics coating. That particular Astec didn't fare too well in Ca. Too much ceramic in the formula and lots of what you see there. I enjoy your videos 👍🏽. Keep them coming.

Acrylic is horrible, especially on metal. Don't be delusional.... or be delusional and paint your car with acrylic because you think it's so great.

In actuality, the problem is way more complex than what he's making it sound. It could have been a cheap coating. It could have been poor Surface Prep. We have no idea how old the coating was in the first place. It's very important to recoat your roof when it's necessary, not when you have leaks. It's also important to use a rust inhibiting primer underneath your top coat and seal off your Fasteners with caulk. His logic is very over simplified.

At 9.15 when you screw the sheets together and water comes out. Can this be due to condensation running down underneath the top sheet into the lap? Sealing the top surface of the joint keeps this water in. There is a reason why you should probably leave the lower edge of the lap joint open to drain. The alternative is to seal the top and the bottom of the overlap to keep the condensation out, making sure you use screws with washers to ensure the water tightness there as well.

I originally thought the same, that condensation is trapped one's I closed the seams. Come to find out that there is no condensation due to the insulation on the inside. If condensation was an issue, then all the seams would be leaking almost every day. So, I realized that the seams were so rusted because of the acrylic coating that trapped the water in, I then decided to clean every seam up and do a proper seal using Turbo Poly Seal and sometimes Super Silicone Seal

I'm sorry but you don't know half of what you're talking about. The roof is rusted and cracked because the acrylic coating was never reapplied to spec and/or the roof wasn't prepped/coated properly.

Interesting topic. I plan to paint my roof with a white acrylic paint like that. There is a difference though. I see that you had ice underneath the paint. My house is in the tropics where I NEVER have ice formation. I think the melting and freezing of ice (which causes expansion) is a major cause for the paint to be pulled off the roof. Even if it would affect the durability of my roof, it's probably worth it painting my roof, because of the aircon energy I can save from painting it white. I do have a lot of expansion and contraction from the hot sun, but perhaps the white paint can help to reduce that expansion a bit.

Just like some of the under coatings sprayed under cars on the frame. Some just trap the water & salt causing it to rot out faster.

Sold in 5 gal?

I have a Galvalume roof and would never just slap an elastomeric coating on it without surface prep. I would first spray it with a bleach solution to kill mold and bacteria, rinse, and then make a dop stick by stuffing an old athletic sock inside another one and zip-tying it to the end of a screw-type wooden rake replacement handle. I would get a gallon of Ospho rust converter and saturate the dop stick and dop each screw, twisting the stick to get thorough coverage. I also would seek out any rust (generally not a problem unless you let the roof go way too long before taking action). I would then use aluminized fibered roof coating to cover each screw and seam before applying elastomeric coating. I would then wait several days until the coating had cured and then apply two coats of elastomeric coating, letting the first coat dry thoroughly.

Thanks so much for this. A friend mentioned he used marine primer on his roof. Does that work?

Your teachings are very good. Thank you.

It's called washing very well and priming all your bolts and edges then coming through and spraying it correctly alot of painters don't know the proper way to spray always spray your corners and edges first similar to cutting in maybe 3 panels then come back and spray your face surface I've sprayed many metal roofs and never got a call back it's all about taking your time and taking pride for your customers

@@angryhands9564 I ended up going with a product from Sherwin Williams called bond-plex. Even had it matched to my paint color. Holding up so far.

This is just an example of a bad job. My grandfather, my Dad and I have a combined experience of over 80 years of roofing. We have seen acrylic coated coated metal last for 20 years without a recoat. On the other hand, we have seen them fail just after 4 years on some bad jobs. This video is not a good representation of an acrylic coated metal. Just bad coating or bad preperation.

Hi, I’ve been reading the comments and have a question. I just built an Arrow metal shed in my backyard and I want to waterproof the metal....some parts already have some small rust parts😡 I don’t want to paint it, what clear coating could I spray over it to weatherproof it? I live in South Texas where it’s ALWAYS humid so any recommendations would be appreciated.

1. A combined experience doesn't mean a thing. Technologies change rapidly all the time. My son who was with me for 8 years has his own roofing business and is already is in other types of roofing applications. I stuck with Torch Down which I still believe is superior to any other roofing system. 2. Acrylic coatings are water-based paints. There is no latex or acrylic coating that can last 20 years on a vertical wall without being compromised. On a metal roof that gets super hot, it has less of a chance. Then all these paints shrink. As seen in the video. It is almost impossible to prepare the surface of the metal roof in such a way that it would be free from crut and dust. I have seen the same thing over and over again and every coating I saw was applied by so-called "specialist" in roof coatings. They all have failed. Now I really appreciate your comment, because there is some truth to what you said. Standards and quality have dropped. Maybe there are products that are designed to withstand the elements. But as you said, bad products and bad preparation make for an expensive job. Thanks, buckethead151 you are a good man

You miss the point. Any sealant is not equal to others, and the Fleece is the secret to the strength

I would have chemically treat the rust first to neutralize it. Grinding off thick rust and covering it up just looks good. The rust remains and grows again. IT is a band aid that looks good. The rust remains.

Can you do a video on your opinion on flat roof safety barriers?

@FlatRoofDoctor

4 жыл бұрын

Hu Andrew. I am not an expert on any safety stuff. I don't follow OSHA rules on roof safety because it is impractical. I would be out of business if I had to set up a safety thing every time I do something on a roof. Residential roofs are to small to setup safety flags and barriers. On commercial roofs, to have flags with a safety line 5 ft from the perimeter is impractical. Putting a harness and then tie yourself down because I am going into the 5 Ft zone of the perimeter does not make sense. Anyway, I admit that I had close calls falling off a roof several times and flag lines would have prevented that. But not 5 ft form the perimeter. Anyway, it is such a big subject that it would be impossible to try and discuss it here. Anyway, thanks for your comments Naas

CI Roofing I Have to agree and Disagree with your opinion We have Sprayed over 700,000 sft so far in 2020 of Acrylic on Metal Roofs and don't have that issue At the end of the day its all about proper preparation and cleaning Theres is a lot of flyby night shady roofers out there So I feel you not being partial to the product that Hundreds of vendors sell the Acrylic The application you have applied is the basic Roof cement that I totally despise that makes by Coating look bad after it dries because it shows thru I respect your view But I still trust Acrylics if applied correct

And whats the black stuff you put??

Silicone coating fits dry and hot areas more since it’s UV resistant

Absolutely! I see the eyes

I will point out some facts. 1) Surface preparation is everything on any roof coating. a. Remove any loose rust with a wire wheel. b. Treat solid rust with an agent that chemically changes the rusted surface. c. Replace bad screws d.Pressure wash and THOROUGHLY DRY. Make sure pressure wash removes all loose material 2. Epoxy is best by acrylic will probably work if you follow surface prep. It is almost cheaper to replace than to properly coat depending upon surface preparation required and material choice.

RIP that man

We love coating metal roofs 😊 Love your videos though!

this roof was not cleaned very well no etch primer and was over coated bad job

I have been coating roofs for 20 years . The best way to coat a roof is to, patch all nail heads with through the roof / geocel. And coat roof with asphalt aluminum non fibered . Asphalt aluminum wears off and never peels , all silicone and acrylic will eventually let lose over time and then you have a mess. Also asphalt alum is a rust inhibitive roof coating . This man knows what he is talking about
