Advice on re-doing my EPDM roof

Hello all, hope everyone is healthy and safe.

Just bought a 2000 Triple E Regal, 24.5 feet with an EPDM roof. I noticed it is chalky and the black is starting to show through. I would like to redo the roof before winter storage (outside of Toronto) and was doing some research. Dicor seems to be the go to product, but I noticed some other elastomeric roof coatings available nearby. Rust-O-Leum has a product and there are others.

Some of the products say not for EPDM roofs, some are, and some seem more highly rated. (Like Heng's) Any experiences or advice? Let me know.

Thanks

All of my research pointed to going with the Dicor 2-stage system. I did it that way, and it's worked well.

If you do the same, buy more of the Stage 1 Cleaner/Catalyst than you think you need, and spray it on heavily, and then brush it a bit before lightly pressure-washing it off. I bought JUST enough, and ended up skimping in a few small areas, and so adherence of the Stage 2 coating was weak in a few spots (since fixed.) Everywhere I used sufficient cleaner, it's held up well.

Interesting! And your roof was EPDM? I'll check into it as well. Thanks!

Not to be a party pooper, but two weeks is hardly a good test of the roof coating.

Only time tells that tale.

Please come back and update us after your first winter.

edpm roof

I tried the coatings when mine started going bad. you dont mention how old the roof is. The coatings are really just a band-aid. lasted a couple years. I ended up re-roofing mine. A tough job to be sure. Did it myself and it took a week of solid hard work. My cost was about 1500.00 for everything. i would recommend at least two people for the re-laying of the edpm but other than that it can be done with one. Im 64 so took me awhile but it can be done and its a more permanant solution(at least for 8 years).

It’s 20 years old but I don’t have any documentation of when it was last done. I don’t think I’ll try a new roof this year but maybe in the future.

recommended for EDPM and TPO. Live time warranty for what that is worth.

Henry's Tropicool. 100% SILICONE. They answer email request the next day. I never did try to call. I covered gutter to gutter. Right over the ALM and rubber screw covers.
Had a previous 5th wheel professionally done and this is how they did it also. You need stiff brushes not soft. Brush one way.

I see lots of reports here and other RV sites and a variety of EPDM roof coat products get used. The only problems that I see reported are attributable to poor prep work, not one brand vs another. Some of the popular choices include the Henry's Tropicool, Kool-Seal RV (specifically for EPDM vs the regular Kool-Seal), Liquid Roof, Heng's Roof Coat, and Liquid Rubber.

Sorry to hear you had a poor result. Henry's TropiCool, however, offers a lifetime guarantee when applied correctly. 5 gallons cover a 30' roof, one coat only required. Cost $250, including tax and rollers to apply it. Thorough cleaning and prep is key. (I'm not a paid spokesman, just a customer.)

Right on. However, a cursory internet search will reveal many satisfied users over several years who attest to its durability. The few who reported problems did not prep adequately nor follow labeled directions.

Hello fellow Triple E owner

Ours is a 34’ 2001 Embassy. Re-did the roof with Henry’s Tropic Cool in 2019. Very impressed with the product and the result. Rolled on 2 coats after prep and Dicor caulking. Had to go south of the 49th to a Home Depot to get it as we can’t get it up here for whatever reason. A 5 gallon pail with about 25% left to pass onto my brother in law for his camper. Check out my pics .
Good luck.

I have a 2005 Montana 5th Wheel. My roof is in good condition but I’d like to coat it before winter. I have no clue what roof material I have. How can I find out what I have?

I just did my Jayco with Heng’s Roof Coating. The hardest part was the prep and cleaning. I washed it at least 4 times. MoldArmor did a pretty good job getting the grime off.
Removed the AC cover, fridge vent cover and 2 MaxAir covers. Added some Eternabond and Dicor self leveling sealer where it was needed. I was in a bit of a rush to beat the leaves falling which is coming faster due to the drought.
Anyway I think it came out nice. I can’t see it from the ground but I knew it needed attention for at least two years.
