 You know, you look at the cheapest one, that guy's not replacing the flashing. Gee, do I need flashing? And you call the other guys, like, why is your so high? I noticed you got flashing. He'll give you the reasons why you want to replace the flashing. And it's amazing. And also amazing when they give the bids. There's people that fly drones over your house. They just get the measurements. There's other people that get up on the roof and they really find out what the issues are. So get three bids and compare them and learn from them.
