Roof Sealant

I'm stripping most of the old sealant off of my roof and re-applying. Does anyone know how much sealant is required for the typical coach?

Front cap joint, rear cap joint, two vents, fridge vent, plumbing vent, skylight, and the big TV antenna baseplate.

Not sure how long your coach is. ( I'm on my phone and signatures don't show up) I just completed my 38' and did the seam along both long side caps so perhaps more than you need. I used 2 tubes of non-leveling lap sealant, 15 tubes of self leveling lap sealant, and 2 tubes of butyl skylight sealant. Also a quart of acetone to clean everything really good before applying. Good luck!

When we purchased our new-to-us MH, one of the first things I did was apply Eternabond tape and Dicor caulk to all seams on the roof. A little water can do alot of damage.

Eternabond is an emergency or last resort repair solution in my opinion. Don't use it to seal your roof. It fails over time just like any other sealant and is an absolute nightmare to remove.

Sorry to disagree!! Yes, it can be used for emergency repairs, but it is not limited to that. Per the Eternabond website "How long does EternaBond® last? Because EternaBond® is made using MicroSealant Technology®, depending on surrounding conditions, EternaBond® has an estimated life expectancy of 18-35 years if applied correctly. The "pre-activated" shelf life of EternaBond®, stored correctly, is 5 years!"

I would not want to ever have to remove a roofs worth of eternabond. Just my opinion, lap sealant is much easier to maintain.

It is not a temporary repair
Like all products must be applied correctly
It will last longer then most people will ever own the MH
