I'm a handyman and replacing the plumbing vent roof flashing is a common jo= b. In the past I have removed the fewest possible number of surrounding shi= ngles, removed the old flashing and installed a new one, and replaced the s= hingles. I could save the customer money if I could just slide a new flashi= ng over the old one. Would that be considered bad practice in your opinion?
We sent a man to the moon but we don't have vent flashings that last as lon= g as the roof, what is up with that?
Thanks for your thoughts!
