Roof maintenance 2022

[peter.fisher]

Hi all. Any recommendations for cleaning / resealing the roof on a 2022 Keystone Passport 268BH? Any idea which roof is standard on these?

Most likely TPO. Use Aloha products for the best results.

You shouldn't need to reseal the roof after just three years. Clean it, sure; re-caulk any cracks, absolutely. But the TPO itself should be just fine. You wouldn't be resealing it, you'd be sealing it for the first time. The TPO itself is the seal.

Wash and then treat it with RV Rubber Roof treatment. It puts a UV protection on the roof, makes the roof smooth as glass, and seals all those billions of tiny pours.

Your trailer has an Alpha Systems TPO roofing membrane. Go to the Alpha Systems website and click on the PRODUCT CARE tab, then click on ROOFING and read what the manufacturer has to say about using "EPDM SEALANT PRODUCTS" on a TPO membrane. Here's the link: Product Care - Alpha Systems LLC and here's their statement:

I called Keystone and identified what roofing material I had which was Alpha TPO. I called Alpha and Dicor and found that Alpha is the preferred LAP sealant to use and regular dish detergent works good for scrubbing with a brush. No treatment needed just using LAP sealant around any openings and seams.

Call Ford and ask that question, they'll say "we prefer you use motorcraft products". Same with GM and AC-Delco or ask RAM and they'll say MOPAR.

Truth is that all TPO roof membrane from any manufacturer is going to be "softened and potentially disfigured by the mineral spirits used to keep ALL BRANDS of roof sealant in a semi-liquid state until it leaves the tube. That was the "original issue" with using EPDM sealant when DICOR first introduced TPO membrane to the RV industry back around 2010. DICOR recognized the problem and developed the DICOR LO-VOC sealant line specifically for TPO membranes. The LO-VOC sealant has less mineral spirits in the mix and doesn't disfigure the TPO membrane as much.

Then when Lippert first introduced Alpha Systems TPO and "low bid DICOR" to dominate the market, they recommended using DICOR LO-VOC sealant for use on the A/S membrane. Then, a couple years later, Lippert introduced the Alpha Systems line of LO-VOC sealant to compete with DICOR and pulled the recommendation to use the DICOR products. Strange how that works, eh ???

Sure, but my rig is under warranty and Alpha says the warranty is void if I don't use their product. At $14 a tube it's not worth arguing about.

Funny how my 2014 Hideout had all Dometic appliances & accessories and my 2024 Passport has all Lippert.

I called Dicor, they did not recommend their product on an Alpha TPO roof FWIW. The Alpa sealant is readily available, similarly priced and it works just fine.

On the Motorcraft parts deal here in the last few years if you have a Ford product and need electronic sensors you are miles ahead buying genuine Motorcraft parts and they better be from a reputable source, phony parts are now very common in genuine looking packaging.

Lippert has a "unique ability" to sense the market downfalls and buy the competition at the lowest point in the stock market, then change the competition's manufacturing lines just enough to make the products at a lower price than ever before.... Then they introduce the new lines, offer the RV manufacturers a lower bid for the next year's component requirements, then raise the price the following year. When the RV manufacturers balk at the price increase, they look around and find there's NO OTHER SOURCE TO BID AGAINST LIPPERT.....

Funny how that works, eh ???
