Hot Water Runoff Corrosion

The combination of hot water and copper is detrimental to all types of roofing, and hot water from copper pipes will exacerbate the corrosive effect of copper itself.

Water from the exhaust pipes of hot water cylinders or pressure relief-valves must not be permitted to discharge onto metal roofs. The copper pipes of solar panels, air-conditioning or other ancillary equipment must be sealed to avoid runoff onto any metal cladding or gutters other than copper.
