100%Silicone vs Elastomeric coating

My 2000 square foot roof that is displayed in this video really just needs replaced, due to several layers of preexisting roofing. I did some jerry rigging just to patch the holes, I was trying to go cheapest way to stop roof leaks, I have put about $8000.00 into the roof so far if I wasn’t so lazy in the first place I could have stripped it and did it right in the first place but of course I tried to go cheap, now if I did re-deck it and put down the silicone on new roof, this would last at least 25 yr for sure, the silicone it’s like creating a rubber sole on the roof.
Found it at lowes silicone roofing. I just wanted to add if you buy this stuff in the winter it seams to be over $100 per 5 gallon bucket cheaper than the summer, at end of summer it was about $350 and now in the winter had to buy more it was about $250.

[@mikenoble8517]

I used 100% silicon from Henry the product is tropi-cool. . My house is in there demo video. 5 years and no regrets. The roof is cement with Rolls of bituminous waterproofing membrane. This is a Florida home and we receive 60 to 70 inches of rain a year but the biggest surprise was how effective it slows down the suns heat by reflecting it away and thus penetrating the roof. It has reduced our summer time HVAC bill approximately 35%

[@style_icon997]

Did you apply it directly to asphalt shingles? Did it stick to it well?

[@turbocon86]

If you are only paying $77 for a 5 gallon pail of modified acrylic, you should expect those results. The best modified acrylic elastomerics are in the $200 for a 5 range. Both products have their drawbacks. The biggest one for me with silicone is that nothing sticks to it. That makes future repairs and modifications to a roof coated with it very difficult. I've been using modified acrylics for two decades and if you use a base coat, poly fabric, and top coat system it stands up well. The only drawback is having to have near perfect weather when applying it. Silicone is much more forgiving in that sense.

[@829joliver]

Even with "perfect weather", there's a bit of a gamble. Shortly after I finished the second coat of elastomeric coating to a flat garage roof on a late July afternoon, a "pop up" thunderstorm unexpectedly rolled in on what had been a cloudless day. In the span of ten minutes, my labors were now all for not...

[@raymondmontgomery4795]

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

[@backendhandyman]

I’ve recently came up with my new motto. “May not be the right way, But it’s my way.” I really don’t know what I’m doing most the time just trying to figure it out, and if I learned a valuable lesson I’m happy to share the value I guess… I will say with Any of the silicone roofing, I wouldn’t recommend going over a several layer roof. When I got this building, it had 3 layers of patched up, tar, asphalt, elastomeric and stuff I couldn’t tell what it was, I was thinking thick rubber would fix it, but biggest issues was over the thick Tar spots, in the summer the tar would heat and crack, and that would cause splits and bubbles in the silicone for me… but I wasn’t really 100% on the proper prepping of the surface either. It should have all been torn off and redecked, before this was applied. So by the time the building sold, I had $8000 -$9000 in roof repairs for the 7000 sq ft roof, if I would have removed, redecked, and then did it, I’d say it would have been cheaper, and I could see this stuff lasting 50+ years if done right… although not sure how deterioration is over that long of time from the sun. Thanks for watching!

Just did my 40ft 5th wheel roof with APCO 576 pure silicone sealer. No looking back, it’s a bit expensive but well worth the extra cost.

[@surgio154]

We all know the silicone is better on a flat roof but the elastomeric works real well on a slanted roof and is not wet after 24 hrs, it dries in 1 hour , my roof is slanted just a little and the elastomeric works great , I keep adding more layers every year to freshen it up , all my low spots I use the silicone , where the water pools

Thanks for sharing this information with actual results. Great help and much appreciated.👍😀

[@stevesummer4057]

I prefer the white because it reflects the sunlight . Sun on a roof damages it fast from heat.

[@stevesummer4057]

Also before you use the white stuff make sure your surface is clean wash it off with a hose with a hose let it dry for a couple day days in the sun other otherwise the white stuff will start looking dirty, the dirt will mix and come through it. blow it off with a blower each before you work each time e even when e even between coats if there a day apart on the white stuff , let water on it dry it's . blow it off with the cordless blower I use a battery one. It's elastic will dry in a few hours if it's summer time or Sunny day out Like 75 or above

Acrylic (Elastomeric) is not good for flat roofs because the solvent is water. Water will emulsify it after it has cured. Silicone is fine under ponding water and it doesn’t break down in UV light. Will last for decades.

Good vid. I had the pros do my flat roof that had old silicone. They power-washed, filled in all cracks with UNIFLEX FLASH and then 2 coats of UNIFLEX 44 SILICONE. THAT ROOF IS SUPER Solid. Like almost rubber. I tried a smaller roof overhang myself with elastomeric. That stuff is so thin, even with a few coats. I would def go with Silicone, lot more cost, but well worth it.

[@backendhandyman]

to me it was a no brainer.

[@2agunguy5]

Roofer here, elastomeric is water based and when power washing a roof off the water will flow off white....loosing breaking down the product. Power wash a silicone coated roof you get perfectly clear water, what's the old saying the proof is in the pudding! Most roofers spray on elastomeric coating which is thin, silicone most of the time (unless you have a very expensive silicone sprayer) is rolled on which is much thicker. Silicone is superior but it is also more expensive. You will have to recoat every 3-7 years depending with elastomeric where as silicone you may never have to recoat! I prefer silicone coatings but depends on the customers plan for the building. As far as your video, cleaning it the way you did is overkill, power wash it off with a 40 degree tip watching how close you get to the deck, push excess water off the roof with a push broom, blow dry with a leaf blower, tape any seams or cracks, or use Sherwin Williams one flash, coat by dipping a 3/4" nap only pour from the container at the end when you no longer can sink your nap in. Most silicone says one coat is good I always do 2 coats.

[@backendhandyman]

R 808 this stuff goes on like paint, one fair warning on a deck surface is once it’s on it’s slick, I’ve heard of people sprinkling sand on top of the final coat to create a less slippery surface, when it rains this would make a great slip and slide lol, but I just cleaned everything best I could and it bonded pretty good.

It is crazy how many people misuse the term elastomeric in coatings. All coatings are elastomeric, all of them. Do they stretch, yes. interiors paint not sure much, but those aren't coatings. Those are paints. Caulkings, roof coatings, silicone, acrylic, urethane, polyurea, thermal plastics, all of them elastomeric.

It looked like the dried silicone in the bucket tore pretty easily -- is that a concern. How does silicone durability compare to Liquid Rubber ? Thanks for the video.

Dave Bean it pretty much is rubber, and the elastomeric was easily torn but the silicone was like a rubber coating

[@sien481]

You're an idiot.

[@JoeLinux2000]

There is a so called liquid rubber coating which is not silicone based. I have not used it, but reading the comments it appears adhesion is somewhat poor. You can read my long post on the subject, but I think the premium acylics are extremely durable and can be reinforced with fabric in any problem areas. Best of all it's easy to apply and clean up is easy. Any needed repairs are very easy. Use a brush or roller. Do not pour a large pond out onto the roof to roll out as is seen in this video.

[@davebean2886]

[@raywite6665]

Yep and when it does and water gets between the layers it is there until you do a tear off.

[@adventurefuel5172]

It depends on the application and situation. Silicon would be better personally for a flat garage at home where I don’t want to touch it again, but in facilities maintenance we have a limited annual budget so we need to stretch and that material price hurts. I can do elastomeric on a building in 2020, then have it back in the rotation for recoat in 2025, and I can do a recertification of the 5 year condition for accreditation. Labor doesn’t count in my budget and I got to keep my guys busy.

Elastomeric is a term meaning "Able to accomplish 200% elongation or more" it is not a type. It's like saying hail rating, permeability, or flame spread. Silicones are in fact elastomeric, in most cases. The 2 products have different uses and resistances, what one is great for the other isnt.

[@backendhandyman]

No longer own the property. It did keep piping up leaks though. Like I said it was a temporary fix to a long term issue. The whole roof was layered with previous layers of roofing, and didn’t help with the parts that were tar... the heat from the sun would actually heat the tar and make it swell and contract which impacts the silicone pretty bad. Especially if you walk on it a lot, little nicks and cuts can chip at the coating making it leak. Honestly I could see if it was original layer, prepped and layered as just that the silicone would last way longer than tar, and shingles. It really is a rubber coating.

@@vikramparmar8093 well that’s where the gamble comes in. See when I did this, this roof had roll roofing, silicone, elastomeric, tar, even had some shingles in spots, when the elastomeric starts flaking off, it makes a poor base for the new coats to stick too. By the time we sold this building I had almost 10k in roofing product on this roof. And mine still leaked, most my leaks came from tar under the silicone roofing cracking and creating more holes due to the heat. Now the part that had the elastomeric coating I was able to go over it with silicone, as long as it’s thick enough coating… however, by the time mine was all said and done, I wish I would have just stripped all roofing and added a whole new roof, since I was doing it myself, it would have been about the same price as what I spent adding more and more coatings of silicone and elastomeric. Main reason for this video was to show the difference between the two. I’d put it this way. If the roof you are wanting to fix has several layers of pre-existing roofing this will more than likely be a nightmare, but if your pre-existing roof is really sturdy and in pretty good shape, try it out. I would recommend no less than three coats for the roof though, and if your not planning to re cover the whole roof, I’d stick with the elastomeric just for spot fixes, and if you can’t get it clean where nothing is flaking off it may be a waste of time and money all together, cause if I remember right the elastomeric gets kinda chalky and that would create a horrible base to coat.

the elastomeric coating needed a primer

Never seal your roof with silicone! No repair will ever stick to it later!!

[@backendhandyman]

Have a pretty good point, however you can always add more silicone or put roll roofing over top.

Tell me a few brands we can trust. Silicone.

Well most DIY people don’t, this video is just to show the main difference between the two... don’t like it cool, have a good day 😉

Will silicone be ok to put on an older mobile home metal roof?

[@backendhandyman]

If it will adhere to it I don’t see why not. I used it on top of my box truck, and I’ve seen it used on camper trailers

[@chadhaire1711]

use 3 coats......

[@kendalgee5808]

Theres you tube videos where silicone on metal flat roofs got a pinhole, then the entire metal roof had rust, lmfao. lol. Don't do it. Im a year late. But go back in time and don't do it.
