I really wish I could give you an idea of the cost but I have not priced things out in a long time! I do know that materials have almost tripled since the pandemic, like copper fittings, valve’s, and even solder is $40 per roll. Whatever you do, don’t go with the low bidder and if possible try to get a reference! I just went through hell with a roofer that was highly recommended from friends and had great references! The price will probably shock you Best of luck to you
