Roof material

[JOglesby]

Where do I find the information that tells me what material my roof is? TPO or EPDM or......?

Pull the skylight in the bathroom and look at one of the edges of the roofing material (you may have to remove a staple). Black on white = EPDM. White on white = TPO.

Or the garnish ring on the vent.

Unless someone has replaced the roof on your trailer, all 2021 Bullet trailers have an Alpha Systems TPO roof membrane.

Verify that by looking at the backside of the roof membrane stapled above, as indicated above. Another way to make sure is to feel the roof surface....

EPDM is smooth and TPO has a "slight pebble grain finish"....

[JOglesby]

Is it common for the slide to have a different material? The main roof is the textured finish and white on both sides so pretty sure it is the TPO, but the slide top is smoother.


So if they are different they require different cleaning and treatments?

Thanks for posting this: EPDM is smooth and TPO has a "slight pebble grain finish".

This has been the best description of roof material I've seen yet.
