Bubbled up roofs on the hwy

We were on our way to Florida in July and someone in a travel trailer came along beside me and rolled their window down. I had that sinking feeling something was wrong and rolled my window down. They yelled over the road noise that my roof was raising up. I said ok and thanked them. We angled our side mirrors up to try to see the roof and sure enough we could see the front part of our rubber roof billowing up. I made it to our campground and took a look. It didn't tear (luckily), but I could see where it had pulled out from underneath the front strip a bit. On the way back home, I used rope and lashed it down to prevent it from ballooning. Made it home fine. Now I have to fix it.
