Q: My friend has a new 9,000-square-foot home and has had problems with the roof leaking. The roofing man and two painting guys have told her that the caulk on her roof was the source of the problem. They told her that she should have it checked every six months for cracking and possible replacement because the caulk doesn't last long. I have never heard of this before and was wondering if they are pulling her leg or if this is a real problem?

A: Tom Silva replies: I've got to tell you, it sounds like they're pulling your leg. You shouldn't need any caulking on a roof with proper flashing. You need a second opinion.
