IF it is TPO, you should be able to reapir by welding some TPO over the damaged area.
My house has a TPO roof, and I have some pieces that were welded (I think TPO came in 3 foot wide rolls). I could not tear them apart.

Looks like TPO since it isn't black on the underside. However, Eternabond and Dicor as others have explained will work to do a quality repair.

Denatured alcohol will work to clean the area before applying Dicor self-leveling and Eternabond tape. For the larger rip, you should use the Eternabond tape to do the repair. The smaller pin holes can be filled with Dicor.

Good Luck. The TPO/EPDM camper roofs have small repairs like this on many campers. Some have holes on purpose due to solar, etc. and the same products are used to keep them water tight.

Seeing that amount of damage and the extended area, it may be best to clean cut a section a couple of feet wide and to the rear. Then patch in a new section.

If you took it to a shop, they probably would recommend a full replacement. If you are planning on keeping the rig for a very long time, some would recommend a sprayed-on replacement roof. Expensive, but a lifetime warranty.

If you are considering a full roof replacement, you can find roof material in the RV surplus stores around Goshen, Ind. at a cheaper price.

I may just tape the rest of the seams on the entire roof. One less worry...
