I wouldn't expect a 20 year shingle roof to last 20 years. That's a true story, even on a good slope. I state that because it seems you are paying great attention to the warranties. A warranty is important but is also mostly marketing.

Would you be wasting $? I can't really answer. I don't know the condition of the existing roof. I don't know if it was properly installed. When you say "rock roof", it could be tar and gravel, could be granulated epdm, could be ballasted epdm. I really don't know.

I can tell you though that if you are considering a low slope membrane which I think is the way to go, though tar and gravel can be a great roof, it really isn't all that common any more. I would be encouraging you to consider a properly install PVC roof system, perhaps even EPDM. Either are single ply and either will last up to 30 years when properly installed (ask for a 30 year system specification) and maintained.

Understand when purchasing a roof that typicaly (not always) a longer lasting roof will require more upfront investment than a cheap quicky commodity roofing system.
