I’m on my roof AT LEAST every other month and it’s unusual that I don’t have to address some point of sealing. It’s not rocket science. Just clean or remove any cracked or suspect area and apply the appropriate self leveling RV lap sealant. I also carefully inspect all windows and other penetrations and seal those as well. Even still I find occasional leaks. The warranty is for 3 months because with all of the flexing and weathering that’s about all you can reliably count on. Just my opinion, of course, but it comes from hard learned lessons.
