Some guys are using copper sulfate and a sealer. Some are pro rating it and some are just counting on the customer never calling back for whatever reason. I use to have three year warranty now offer five. I sell extended warranty if I get a call back so I don't leave empty handed. If they call you back near then end of the warranty period they obviously see the value of the warranty and will buy extension. If they call you in the middle then you might not have done as well as you could have use the opportunity to ask for referrals or other work.
