Is this because you just can't trust factory sealant or because of the environment (heat/UV) wearing the sealant out ?

Lap sealant is NOT good forever... constant checking on it on the roof, with so much to check, even a tiny bit loose from the surface on a seam can create a big headache inside.

Perhaps it is just preventative maintenance?

certainly for me it was PM... I now check my roof once a year from a ladder.

Do you e-bond around all roof seals such as the vents and air conditioners? It seems if you are going to do it you might as well do it all.

I did that... although I was worried about front/back and side seams mostly... I did vents, but not AC (YET!)

If the factory roof sealant can't be trusted for long term, why do they not e-bond everything to begin with if it adds value? (cost I guess)

I believe the membrane mfg and the sealant guys work together and produce compatible products... caulk/sealant has been around forever.

Much easier and faster to apply a ton of caulk up there... E-bond is a bear to get off if you goof up the install. Once it is down, even slightly, it is stuck there for good. the adhesive is blocked from UV by the plastic backing on the tape. I have seen no deterioration in nearly 3 years of the tape surface and the underlying adhesive.

What is the life expectancy of the e-bond if it is correctly installed?

10 years according to website, probably longer... clean, dry, alcohol wiped surface to remove contaminants...

Thank you rsdata,

I was hoping you would reply from what I read on your other posts. This helps bring it into perspective. I'm going to consider doing this to my TT within the next year or two, depending on what I see up top. Like I said this camper fits our lifestyle, towing, and plan to keep it a long time.

Also, This sounds like a good business to be in, re-bonding camper roofs!
