Best Seal Air Leaks in Phoenix AZ

Noticed a wet spot on bathroom ceiling after storm the previous night.Jay came out and reattached a vent that had been dislodged from strong winds from the day before. He was up on the roof for about 10 minutes and came and told me that would solve the leaking problem. I was amazed because two other companies came and gave me estimates of 700 to 1400 dollars to fix the problem.
