What kind of roof do I have

[Rich R]

2019 Outback 328RL

The Keystone manual for 2019 lists 2 different roof coverings that could be on the rig each with different maintenance requirements.

TPO Roof
or
Alpha Flex TPO Roof

Anyone know how to tell which is which?

This website >>>> https://www.rvusa.com/rv-guide/2019-...-328rl-tr38086

btw - great info their on all your specs. Save the brochure pdf.

Shows in the brochure for the TT (yours) just says 1 Piece TPO - Tan

So I would go with "TPO ROOF".

But their are more knowledgeable people here, like Chuck and the gang, so I'm sure someone will confirm.

A "tpo" roof is a roof with material made of thermoplastic polyolefin. Alfa Systems is a manufacturer of tpo roofing so the 2 statements you posted are referring to the same material but one adds the name of a manufacturer of which there are many.

This is what I use >>>>

Clean and protect (summer application)

Dicor Corporation Dicor RP-RC-1GL Rubber Roof Cleaner Gallon
Dicor Corporation Dicor RP-RG-1GL Rubber Roof Protectant Gallon


Re-seal on top of the bumpy edges that looks like dried concrete
4 Pack Dicor Self-leveling Lap Sealant

The Alpha Flex TPO Roof manufacturer specifically states you must use their products for sealing/maintenance to prevent damage to the material. Now I'm not sure if that is real life reality or if that company is trying to sell their products, but they were very specific.

We use Dicor products on Alpha TPO roofs, Haven’t seen any adverse affects yet.

Alpha specifically states that to sell their products. There are many out there that state they are safe for TPO roofs and since TPO roofs are basically the same they should work fine. Since I had about 20 tubes of Dicor from my last EPDM roof I've used it on my TPO roof since it says it is OK for them and I've had no adverse effects.
