Question:

I have watched your video to replace an RV roof and he used the LaSalle Bristol XTRM PVC roof material and highly recommended that material. You also sell the Alpha SuperFlex system which is supposed to be better. Is it also PVC? Is it better and last longer than the Bristol? I want the best with least maintenance. Thank you.

Expert Reply:

The Alpha Systems Superflex RV Roof Membranes like part # AL42CV uses a TPO membrane and the LaSalle Bristol RV Roof Membranes like part # 3441700534142711435 uses a PVC membrane. The TPO membrane is more resistant to punctures and wear but the PVC membrane is more energy efficient. These are the main differences but they both work well on RV's. I recommend the TPO due to the increased strength which would therefore mean less maintenance.

I have attached a full list of options below.
