Why RV different than house?

Just a question. I've only been RV'ing for few years. I follow all this talk on resealing roof, etc. Why is an RV roof so different than the roof in my home? The roof in my house has wet vents, exhaust vents, etc coming through the shingles. Never in years do I ever get up on the roof in my home to inspect and reseal. But with an RV I read this is required annually. Just wondering why the RV roof is treated with so much more care. Thanks.

    just4mrg,

    Well, a couple of reasons. The first is probably because your house isn't bouncing and twisting and turning down the roadway. This extra motion puts additional stretching and strain on connections and sealants.

    Also, the construction of most RV's isn't as robust as your home, and a leak, even a small leak left unchecked, can quickly cause very expensive damage to the roof, walls and floors of the RV.

    Third, I'm sure it's a CYA thing for the warranties. "Oh, you didn't check your roof seals every month? Sorry, we can't pay this claim.". Probably an exaggeration, but that's the idea.

    Now, I replace any deteriorating seals on the roof with Eternabond Tape and that seems to solve the problem permanently. Great stuff!
