I have been told by several roofers that they prefer to leave flashing that appears in reasonable condition alone when replacing the roof. It seems to me that ALL of the flashing MUST be replaced with the roof no matter what condition it appears. After all, who is to say that the old flashing wont fail a couple of years after the new roof is put on. Is this a common or correct practice?
Thanks

Adam, find new roofers.They can't be that good if they can't sell new flashing. That is where we always make our money on reroofs.

Adam,In General,If the roof is being laid over the flashing usually stays. If the roof is being torn off the flashing is torn off also.This is not an iron clad rule,however.In the case of a lay over ,leaking or defective flashing would be replaced.On a tear-off we would think a bit before trying to remove sidewall step flashing that was under cedar shingle siding for fear of extensive siding damage.A lot of this is going to be a judgement call on the part of the roofer.Get about 3 estimates from other roofers and see how they are going to handle the situation.If most of them want to leave the flashing intact there might be a good reason for it.If ,however the other 3 guys want to replace the flashing,and your guy is the low bidder who wants the flashing to stay,I think you can figure the real reason.
Good Luck,Stephen
