Ok, I'm a bit puzzled.
As long as I've been on these forums, I have heard some folks say that they would only get an RV with a fiberglass roof and that they WOULD NEVER buy a rig with a rubber roof. The reason being was the extra maintenance required with a rubber roof, that they only last "X" years, yada yada.
Our rig, with a rubber roof, is about the same age as JCat's. I've sealed the original seams with Eternabond as needed over the years and generally just kept the roof clean, inspecting it Spring and Fall. I don't think it'll need to be replaced in the near future, but who knows?
So, I'm surprised that a fiberglass roof needs this type of attention after a similar time period.
Is this type of deterioration unusual for fiberglass roofs?
An inquiring mind would like to know. :)
Thanks,
