Thanks for the video. Just finished mine…I only used 1 gallon! It’s $109 a gallon. I feel like I got it on plenty thick too. But I only have a 21ft Flagstaff travel trailer. I used 4” flex seal tape on the sides and around devices and painted over. Whole project around $200 instead of $6000 that the RV place wanted when it wasn’t needed. No leaks at all!

Thanks to all who gave negative comments on flex seal. I appreciate the info. Seriously.

Do a review after a couple of year we would like to se how well the FLEXY SEAL hold up.

We did this several years back. we removed all the covers and washed the roof throughly with Dawn dish soap to remove and grease or oil or wax build up.
Let it dry we did put ours on with a brush.
It's held up very well, and the roof does not get hot like it used to, and the inside of the camper stays cooler in the summer heat.
It does get dirtier quicker, but once you wash it. It looks brand new.
And I would do it again also, no cracking or peeling.

It looks so pretty also, nice and white and clean looking.

Hilarious, just used some Flex Seal spray to touch up a vent yesterday and then this video pops up. I wasn’t talking about it and my phone wasn’t near me so Youtube must be reading my thoughts.

Looks really good guys… thanks for sharing 🔥👍🏾💯✅

[Michael-iduh]

How is it holding up? I used it on an old pick up truck and it just flaked off after a few months

[kanahn]

Did you get up on your roof often much after it was done?
I'm wondering if it would get damaged by boots etc...

[johnnyg]

You guys did this right over the rubber roof?

[Axeltiguere]

I’m new to the RV community and seems like soon l’ll be exposed to this type of maintenance. How long ago did you apply the seal, and how long is it supposed to last? Thank you for sharing the video. Very nicely done 😊🙏🏽

Do this to sell it to some sucker like me who didn't do my research before I bought my rv

[MontanaWelldigger]

Good luck, I used it on my gutters. Did not work for me, even with lots of prep work.

[anamcneil]

So 3 full cans of that size can in this video is what it took to do your roof? Also what size is your motorhome??

[blakenoble]

People are so worried about being right, if it works for them who gives a shit. If anything, im certain it hasnt hurt what's underneath the flex seal. Flex seal is some amazing stuff im sure it woould work well. RV roofs are notoriously bad antways so what are they really huring.

[dw]

Don't think that stuff is for use on TPO or EPDM roofs.

[iair-conditiontheoutsideai]

Flex seal is great at exploiting people's ignorance to roofing systems. You basically just painted your roof white it's all going to flake off and now no proper RV roofing supplies like dicor or etrnabond will stick to that. This is a great way to make sure you will have to spend $5, 000 on a brand new membrane

[odannyboy]

Is flex seal UV resistant? I don't think it is unless there is a specific RV formula from them.

[alloutofdonuts]

I was considering using this stuff but there’s just too much risk to be worthwhile. Maybe if it was 1/2 the cost. I’m glad it’s worked for y’all tho! But for me at least, the amount of money and prep it takes I think I’ll go with something that’s less failure prone and actually meant for RV roofs 😮. Not to come off sounding like a elitist dink 😅, it’s just I’ve tried ‘alternatives’ and ended up doing it over, costing a lot more time and $¥€£ in the long run. Like they say pay once, cry once lololol

If your roof is shot, you're replacing it at some point anyway. It will prolong replacing. 25 year contractor here
