What are the disadvantages of using copper?
One of the most serious disadvantages of copper wire is its susceptibility to corrosion, that is, oxidation. It has a shorter life expectancy than fiber optic cable as a result of this. Therefore, the problem of copper storage is related to its penchant to be oxidized at relatively normal temperatures.
How do you clean bird poop off a copper roof?

Is copper water resistant?
Copper metals offer excellent resistance to industrial, rural, and marine atmospheres. Dry atmosphere way from the seacoast will produce the least surface discoloration, while industrial and marine atmospheres will produce maximum coloration. Fresh water exposure: Copper tubing is commonly used for fresh water piping.
Do copper roofs get hot?
Copper absorbs less heat into the home. Copper roofing also radiates less heat. The reflective property of copper enables it to deflect sunlight well. You will appreciate this most during the hot summer months.
