<div><br></div><div>At one point when the copper price crashed it was the same cost as enameled steel I considered using it on our roof instead of steel. I calculated the amount of Cu leaching from a 1600± ft2 of it with 18" a year of rain and concluded that it was fine if it was adsorbing into soil but not if it was going directly into a freshwater aquatic ecosystem. For gutters only it's probably too little Cu to worry about unless you are filling an aquarium. By the time the HOA approved our project--a year later--Cu was 4x as expensive as steel. Glad I didn't use Cu, as it saves us $ on an armed guard to keep an eye on the roof...</div>
