Flex Seal

Has anyone used as seen on TV Flex Seal to seal their entire roof? If so, are you satisfied with the results. I have been researching various sealers and this looks comparable price wise with others. A friend of mine has been patching his TT roof in spots for a year now and it seems to be working and not cracking.

Clean up for Flex Seal is mineral spirits which is listed as damaging to EPDM material. I would not use it.

Flex Seal

Yes, Norty I'm talking about doing my entire roof. It comes in a gallon can also. Thanks, Grumpy for the heads up.

I sure would not risk trashing my roof using something that isn't proven to work and damage the membrane.

Is it a newer JAYCO with the Dicor Diflex II TPO roof? According to Dicor, you can use mineral spirits on a rag to clean tough spots on a Diflex II roof. Just donít saturate it with the stuff or pour it on the roof.

And when you apply the Flex Seal you are pouring a mineral spirits based product on the roof.

I've actually thought about using multiple rolls of 6''x50' Eternabond tape overlapped 1/4'' to cover my entire roof. I think I costed it out around $800.

I use flex seal on my gutters of the house, it is sensitive to UV and needs to be top coated if you want it to last more that a year or so. I would not suggest it. Where I didnít top coat it, I just sweep it up. Go with a membrane of some sort like the newer rvís.

You will need far more than a 1/4" overlap. Also, that could be a lot of weight added to the RV for minimal gain. You can get similar adhesive membranes that come on far wider rolls from commercial roofing suppliers.

Frankly, I feel you would be wasting your time and money on a scheme like that. If your roof membrane is in decent shape, just use regular Eternabond on the seams and edges. If the roof could use a coating, use Eternabond's WebSeal on the edges, seams, and to cover any damage, then use a roll and brush on coating designed for your roof type (you can't use a coating over regular Eternabond--it won't stick well--hence the need for WebSeal).
