re: Roof leak

Sometimes during heavy rains, a roof will leak because the roof install or the material choice could have been better based on the design of the roof. That roof could leak today and not leak again unless the exact conditions are replicated a second time. When I say replicated, I mean rainfall amounts, wind speeds from the same direction, etc. It could never leak again or it could leak next week.

This doesn't mean that a competent roofer shouldn't look at and diagnose the problem, but it also doesn't mean that you should jump into roof replacement.
