20 Best Enclosed Trailer Roof Sealant (2023 Updated)

I bought this based on the reviews, the price made me think about it but in the end I bought it. The 5 gallon pail weighs over 65#! It took me almost 15 MINUTES to completely mix the stuff up using a drill!! I used a paint brush to do the entire roof.

I didn’t like how it went on with a roller. The finished roof looks and feels incredible!! I was curious to see how thick it set up using the paintbrush. I put some on a piece of tinfoil, using the same technique I did on the RV roof.

After completely dried it took a little bit of time to get it to come off of the tinfoil, which I thought was a positive. In my opinion, this means that it should adhere to the rubber roof even better because of its porosity.

Peeling the RV Fletcher pair off the tinfoil resulting in about a millimeter to 1. 5 mm worth of product thick on the roof. Very impressive! I highly recommend this stuff, it is worth every penny. I have a 33 foot fifth wheel, even putting it on with a paintbrush I still have about 2 gallons left over.

Five roof vents, 1 AC unit etc… Recommend the stuff, and I will definitely buy it again if I need to.

This stuff is super thick and changes the feel of the roof entirely. I am a full grown man about 230 pounds. The roof before this stuff had a minor flex to it. After doing a single thick coat of this sealer it’s like a rock up there.

No give to the roof. I love it! In some of the more poor areas of the roof I just poured the sealer in the area and spread it out evenly as possible with a roller. Did a total of two coats. I scraped the flaky stuff off before I painted.

I also removed the satellite dish that was I never used and the RV antenna that was outdated. The more up there the more possible issues in the future. I used their tape to cover the holes and areas they were in after cleaning it properly.

I sealed around the edges / trim with an adhesive. I don’t think I will ever have to touch my roof again.

This is really a good product went on easily enough, but took some work to get it on, I used a roller and a brush to get it on thoroughly. First I prepped the roof by scrubbing it twice to get all the dirt up and then let it dry thoroughly before applying.

I applied it later in the afternoon so that I did not have direct sun overhead. It looks really good and covers very well, had some strong rains a couple of days later and the water just rolled off. I bought the 5 gallon bucket and that was way too much, I should have only bought a couple of gallons.

I have enough left to do another coat and my sons camper as well.

Had a couple tubes for months but do to work I never had time to recaulk vents and skylight. Last night it rained and hailed hard for 25 minutes and moderate rain for another 35 minutes. Had towels out soaking up huge amounts of water from the 3 leaks.

I took work off today and 3 to 5 minutes after applying to to problem areas it started down pouring non stop. I feared the worst but no leaks after 1 hour of heavy rain and it s still raining. Great product!.

Great product and the price was excellent. Camping World was ALOT more expensive. ALOT more expensive. So if you need to seal your RV roof this is the stuff to use.

This is an excellent product. Installed a new satellite on the RV and sealed the mounting brackets with this sealant. It looks OE to me and sealant has remained plyable but completely sealed. No leaks at all from those screws holding the brackets.

We have had some serious rains here and its doing its job. Great! Highly recommend it for any roof repairs on your RV.

I absolutely love this product!!! I used this for my RV roof seals where the standard Dicor has been used for years. We have been battling the never ending challenge of leak prevention for our rig every year.

I diligently inspect the roof every 3 months to find the same old Dicor faults of drying out, cracking, and peeling up, forcing me to add more Dicor. I decided to give Ziollo lap sealant a try and couldnt be more impressed with its performance.

The product sets so smooth and just the feel of the Ziollo after it has set gives the impression that is is a lifetime product. Im planning on resealing my entire roof soon with Ziollo RV roof sealant and ( I cant believe Im saying it, BUT) I am looking forward to that project.

THANKS Ray for your time and efforts in creating this AWESOME PRODUCT!.

Great purchase. You can literally paint this stuff on, which is great for narrow spaces. It can also be layered and adheres well to surfaces, even vertical ones. It does take time to dry, but that’s to be expected in a damp climate.

(It would actually be harder to work with if it dried too quickly. ) Four tubes was more than needed, but this is a good thing too — it’s smart to have some extra on hand for the next time the travel trailer springs a leak.

Had to reseal my 1999 24 Foot 5th Wheel, ordered 8 tubes, the product went further than expected. Used 2 tubes on the front seam, two on the rear, then went around 3 skylights, and other stuff having 2 leftover.

very easy to work with. A brush helped going over old and new.

I am a huge fan of the liquid version of this product. I tried the cartridge, and found it nearly impossible to get it to stay down. When you try to end a bead, it pulls off the work. Then trying to get it back down is an exercise in futility.

I ended up having to do an area multiple time. It’s so thick it requires significantly more pressure to get it out than normal caulk. I enlarged the hole in the tip, punctured the seal multiple times, and it still required two hands to get it out of the tube.

This sealer has got to be the best roof sealer that I have used in a very long time. I had a problem with a stubborn leak on a vent pipe, and this stopped it the first time. I highly recommend this product for your next roof problem!.

I’ve used any number of tar-based sealants on roof leaks over the last 4 decades. None were as easy to use or as effective as Through The Roof.

This product creates a good, flexible seal around an RV’s exterior openings, especially when installing new or replacement parts/ equipment. The “no-sag” sealant works well on horizonal and vertical surfaces.

It is still more viscous than many household sealants, and can be a bit messy to use and clean up. As a result, our nickname for the product is “guckempuckie”. With care, it can give you a good, watertight seal that looks good on your RV.

Vertical application not dry after an hour. Pulled off painters tape and the side of the caulk strung out like spaghetti off of clean aluminum.

Great product for trailers and rv units. Must call Dicor on the application and use. It applies differently from other types of sealants. It is an art to make the application look good. All in all, it works and seals like nothing else that you’ll ever use on your RV.

Product is as advertised. Very good quality and value for monies spent. Does everything “it” claims to do. VERY happy with usage and end results Thrilled that Aubuchon carried the EXACT item I needed/wanted.

Works somewhat. Tried to write a specific review twice and lost it. It doesn’t last basically. Yeah also good luck on warranty. No response!Used it on used and new substrate. It does work, but splits and bubbles in spotsWould give 3 stars of they respected the warranty or at least responded.

I have not found anything better though???.

The first pail I received was a solid block, the silicon had already cured in the bucket. I was sent a second pail at no charge. It had been tipped over in transit and had leaked in the box. I tried to use it but it had already started thickening.

It was very difficult to spread.

I’ve used hundreds of gallons of the top brands for commercial roofing and this product is #1 in my opinion because this elastomeric roof coating has silicone in it and is much better. I have repaired leaks for customers with this product when several other roofing companies could not.

So I purchased 4 quart containers of this sealant a few years ago with intentions to do some repairs that were actually not necessary following some roof reconstruction. That said, this stuff sat in my shed for around 4-5 years before I had a chance to use it (not climate controlled – full swing of weather in the NE).

I was afraid that like caulk tubes this very expensive purchase would be a loss but I was pleasantly surprised to find that all 4 containers stayed viable! I had a small leak in my roof SOMEWHERE that I could not pin down.

I decided to just hit every possible infiltration point with this sealant and see (roof vents, waste line vents, a few cracked shingles, etc. ). Well, one of the spots I hit must have been the leak point because months later there’s no further leak evidence even following some pretty horrific rain storms.

I am so happy with the results that I wanted to share a few things I learned while using this sealer. 1) I see a lot of people recommend foam brushes for this stuff, but I would counsel getting short utility paint brushes instead.

My asphalt shingle roof would have shredded the foam brushes and the traditional bristles of the utility brushes I purchased let me really get into the cracks with the sealant. Also – the bristles are a bit stiffer than many foam brushes – good for getting the last of the sealant out of the jar, especially as it starts to cure.

I used a 2″ wide brush (with 1″ long bristles) which just fit into the mouth of the quart jar. I got a box of these things for peanuts a long while ago and still haven’t run out of them. 2) A note about the curing.

some other reviewers mentioned getting gallon containers instead of the quart size containers. Do this ONLY if you are going to use this stuff all at once and relatively quickly. I was very careful to recap my quart jar as I moved about the roof and I still barely got to the bottom of the container before it started to gel up to the point it became unusable.

Unless you have a big project, get a bunch of quart size jars so that the most you will use/lose per job is one quart. Plan your job ahead of time so that you will spend the least amount of time after jar-open.

3) Plan to lose what you don’t use. I carefully re-capped what little I had left in the last quart jar I was using – even did the “breathe into the jar for CO2 layer” trick and the stuff still completely cured within hours.

Once air gets into the jar the timer starts ticking. 4) Be careful cleaning up. I got this on my extension ladder, jeans, shirt, shoes, etc. I was wearing work clothes and work gloves so no problem there, but you would NOT want to get this on anything you care about.

One unexpected bonus – the work gloves I was wearing now have a water resistant side – the sealant coated the palms and fingers of the work gloves and they are still flexible and workable! 5) Be aware that this sealant is somewhat shiny when cured – so if your roof is visible from ground level, the repair patches will be noticeable if you’re looking.

It’s not “ice in the sun” shiny, but on an asphalt roof it stands out. I don’t care because anything was worth nailing that leak, but it’s something to take into consideration. The net sum is that this sealant really works, sticks to anything and everything, and is still pliable and well adhered almost a year later after being applied to a swept but weathered roof in full exposure to the elements.

I can only hope that it lasts until it’s time to re-shingle the roof again.

One day it was pouring & water was dripping through the ceiling in the bedroom. I checked in the attic as seen here in the picture. I could only get a general idea exactly where it was leaking. On the roof I figured it somewhere within 5 square ft.

I coated with about 1/3 the can. Next rain, it still leaked. Coated with another 1/3 can, leaked again. I used the last 1/3 of the can coating the whole area including the side of the ridge along the edge of the shingles.

It seems that was the only area not covered. Since then its rained hard many times and it stopped leaking. Good stuff if you can locate where the leak is.

I have applied 2 1/2 gallons since I discovered this product about 6 months ago. I have applied it on a 2=12 pitch metal roof/deck where it joins the house and on the screws and seams of this new covering and no leaks yet, also on our 1994 RV trailer roof which had some leaks and does not appear to be leaking, also applied to the metal roof of an old (1981) mfg home rental on the Oregon coast and today applied to the metal roof of our rural home that has had a regular leak next to the brick fireplace chimney, covered all joints and screws.

I like the way this product flows into cracks after it is brushed on. I did not like the foam brushes so went to stiff paint brush then to a small stiff nylon bristle scrub brush. The bristle scrub brush was shaped like a wire brush with a handle, this seemed to work the best for me.

as for the product stopping leaks we will see after this western Oregon winter. This product appears to be flexible when dry and does not seem to be prone to cracking like regular caulk or asphalt rain patch.

The clear roof plastic light panels on our metal shed are always bombarded with acorns & branches in the fall and seasonal weather overall can be harsh (baking summer sun, cold winters, wind, etc). We had a few major leaks (a branch poked a dime sized hole in one panel, there were a few lenghty cracks and others leaked where mounting screws were located) buckets were temporarily necessary until we decided what to do.

“Sasho Through The Roof” immediately ended the leaks! It was raining during some of the applications, made no difference in performance, Bottom line is, this stuff really works and fast! No more leaks.

1 quart of this gel-like sealant goes a long way. Easier to apply than caulking gun, used a brush for precise, thick application. Smells alot like airplane glue, so make sure you have proper ventilation.

We’ll find more uses for this, I’m sure! Great product. We recommend and will buy it again, as needed.

I had a roof leak that was relentless. I tried more than half a dozen products. Most of them dried out in the sun and cracked. I worked on this for a year but nothing worked until I found this product.

I liked the clear finish and the way it covered with a sponge brush. I put on two coats and now have no problem and we have had some very heavy rains lately.

Not cheap, but does the job in areas where something else won’t do. Shelf life is somewhat limited and not like you can keep in on hand for a very long time. Order this, because my other had since dried up.

About half a container, at half the price would have been better for my applications.

This stuff is the best sealer available. I fixed an 18 yr. old RV that I ran through a wicked hail storm. No leaks, its awesome! Before starting to seal wash thoroughly with a good detergent like Dawn.

Rinse well and patch tears and holes, seams, and cracks with RV Roof sealer tape. Then put on as many coats as you think it needs. ( the more the better). Allow 3-5 hrs cure time between coats depending on temperature/humidity.

Update; After a year of brutal Texas weather this coating is still looking like new. UV resistance is great and its staying pliant. No leaks or checking from shrinkage. Im very satisfied with this product.

Update-; I had softball/grapefruit size hail that beat all the windows out of my house, and the RV. Busted the windshields out of my vehicles also. 8 days later baseball size hail again broke the windshields that were replaced.

The HENGS roof on that RV is 100% ok. It withstood three ferocious hail storms. I am not exaggerating, the RV is history/totaled/shredded, but that roof doesnt appear damaged. There was a some rain and it does not leak.

i read the reviews on this product and took a chance. The price was more than i hoped but i ordered 4 gallons to do a 1994 10×30′ motor home. I read that coverage was about 2 1/2 gallons for this size.

after a weekend of GOOD prep i was ready for the coating. WOW this was a great coverage product. used about 5quarts (a little over a gallon) for the first coat. Im a journeyman painter and put on alot of products but this covered great.

I brushed the cut work and rolled the flat and put a good heavy coat down and im very pleased with the results. if the product holds up IM SOLD. a bit of advise. use on a cooler day as it will skin over in the bucket and roller tray.

low humidity was about 70 and overcast but no rain. I will put a second coat on and see how it holds up. 2 thumbs up.

This is an initial review, time will tell. The product seems to be of very good quality and has a thickness to it. Pre-cleaning of the roof area is a must and following the instructions is a must. I used dawn liquid but made sure it was washed off completely, had no problem with this.

The product went on simple and easy on my old EPDM roof/after minor repairs were made. I would give the product an excellent rating, but check back with me in a couple of years.

I didn’t find the product to self level. I waited and had to smooth it out/flatten it with a putty knife before it dried. It does seal well though.

I didn’t find the product to self level. I waited and had to smooth it out/flatten it with a putty knife before it dried. It does seal well though.

Way too thick to self level properly. Stays pretty much how it comes out of the tube in a noodle. needs to be lower viscosity. I also have the Alpha 1010 non self leveling- not a whole lot of difference.

This sealant will set up completely in 24 hrs. Also paintable, in about 2 hrs. This sealant comes out of the tube a little runny, but tacks up quickly. Works great for self leveling. It will dry to a rubber consistency.

Completely water proof.

I used this on my travel trailer roof about 5 years ago. My trailer is required to live outside in the elements (Utah winters and summers) and this has held up very well. It applies easily, doesn’t require any pushing into place like regular caulk; it flows into cracks and valleys, providing an even finish.

I do not think I need to replace what is on the roof, but it is showing a little more weathering than I am comfortable with so I will cut/peel what is in place and do it again. Excellent product.

Seems to work well as sealant. Is not entirely self leveling, but more-so than most. Applied to a surface not entirely level it would probably be ideal. Seems to bond well to painted aluminum.

So heres the tuing that got me thinking. rv user manuals instruc one not to use any type of thinner or petroleum distillate (charcoal lighter fluid or mineral spirits) to clean/prep the roof. They claim these products will damage the roof.

Now, Dicor actually has mineral spirits in it to make the sealant pliable when applying and to cure the minieral spirits essentially evaporate. Its pretty hypocritical to teller xonsumers not to use one type of prodcut then advocate to another product with the banned substance as an ingredient.

Why isnthis? Money. All of these products are made by the same organization. Now personally, i think its crap to tell consumers not tomuse something then advocate a product with that item in it. Dicor itself is a self-leveling sealant that is used to seal potential leaks from openings in an RV roof.

It will, after exposure, dry out and crack which can allow water to enter your rv, causing you more problems than you want. I found this sealant after researching other products they have that are used for concrete.

This sealant serves the same purpose and is labeled as a “semi self-leveling” sealant. It does level out but it does not level out as fast and thin as dicor. This actually forms a thick bead on and around the area being sealed.

It has no odr of mineral spirits, i cant read the label to be sure (its too small) but it does have some type of solvent in it. It seems to have a nice flexible seal that may take a while to dry out, keeping the rv protected for years.

It was just a bit less than dicor as well. Im sold on it. I cant attest to how well it will hold up or its longevity, but so far im happy with it. For the roof prep, i uscraped all the old dicor off carefully, cleaned the whole area with a rag and mineral spirits (used sparingly), and applied this to seal it.

Seems better so far. From now on, ill be using this product for my rv roof maintenance as a secondary to the elastomeric sealant tape. That stuff lasts forever. But this seems to be a good prduct. Ill update it in a few year to see how long it lasts.

Resealed the roof of my cargo trailer. Original sealant was cracking and pulling away from the seams. I was told this is due to the high percentage of solvents in the self-leveling sealant used at the factory.

Sika Flex 715 is low in solvent content and therefore less prone to shrinking and cracking. Though it is semi self-leveling which helped me fully cover the seams on the trailer roof.

Works well. A littles thinner than expected therefore it doesnt fill vertical voids very well.

I absolutely love this sealant. I had to replace some skylights and vent caps on my camper. Once I replaced them. I used the roof sealant and it was a dream it went on very easy and sealed perfectly.

No leaks.

A must use when repairing roof vents and other items on your RV roof. Never use silicone you will regret it in short time, this is the product you need to use on your rubber roof.

This stuff worked great to seal lap joints in cargo trailer roof. I’d recommend to keep it warmer (70-80f) before application so it flows easier, especially if application is on a cooler day like I did (40f).

It works well for it’s original purpose. It also works well with sealing broken gaskets around car windows.

Smooth, easy application with a caulking gun. Great to have on hand for indoor problems also.

i stripped the siding off were it meets the roof sealed it and i am waiting for rain

We have had leaks occurring around the dormers on our roof for several years. We have hired people who have caulked around them and stopped the leaks for a little while, but they always returned. The last time we had the roof examined, we were told that the roof (replaced after Hurricane Katrina) was installed incorrectly- the shingles were nailed with a gun using too much pressure, and the shingle placement was wrong, and left gaps- leading two roofers to tell us we needed a whole new roof, which would mean spending $8000-10000.

00. We looked for other, less expensive alternatives, and found this product online. We applied the product this past Saturday, just ahead of 3 days of rain. There have been no leaks thus far, and our plan is to buy more Through the Roof and coat most of the shingles to prevent future leaks.

We are hopeful that our roof problems have been solved. Thank you!!!.

Extremely please with this product. It works as intended. I caution you to have a small amount of mineral spirits readily available in case there is a need for clean up. You must clean up immediately for best results.

This is a very good product. I’ve been camping and owned campers since 1986. Have been using this for the last 10 years. Around the top vents and air conditioner.

Awesome product and fantastic price. Sikaflex 715 is the choice of commercial and industrial construction flashing, sealing and structure joints. Easy to apply, lays flat, exceptional adhesion, lasts and lasts, and performance beats common RV lap sealants by a mile.

IšverstiShow in original languageHello I am glad that I found something to put on my mom’s roof. She didn’t know that the last Hurricane had weakened some shingles and one of her bedrooms had water leaking in.

I have had two back fusion’s and a stomach hernia surgery in the past five years and I will have to get someone to help me put the sealer on the shingles very soon. I wish someone from your company could tell me if there is a way to apply the sealer with a paint sprayer of some kind or is it primarily a brush and roller application.

I have not opened the buckets yet to see how thick the sealer is. If you have any good applications to use for putting this on her roof please let me know.

IšverstiShow in original languageThis is the best and most reasonable priced rubber sealer and even better than Flex seal. I also used a cheap spray sealer as an additive to the primary sealer and my results were priceless.

I appreciated the fact of you changing my first choice of the 5-year to 10-year lifetime application and kept the same price! I’ll always find it a pleasure to do business with you all at Ebay. Sincerely Gene F.

IšverstiShow in original languageI got the product in perfect condition. I had built a handcycle, and built a shed to park it in. Sadly, it’s fall here and temps dropped to below 50 F. and being in a wheelchair and will be applying this to the roof.

So I will if possible review this product after I use it in Spring of 2019. I had hoped to get this applied before temps dropped to low for it to dry properly. From what I read about this it seems impressive.

So I am looking forward to using it.
