Zinc Roofing: Durable and Easy to Maintain

With proper maintenance, a zinc roof can easily last 100 years! This is because the various weather conditions make the material stronger. Over time, a zinc roof discolors due to precipitation, forming a characteristic patina. Because the zinc roof reacts to oxygen from water or the air, an oxide layer forms that completely blocks the zinc from oxygen. Because oxygen can no longer reach the zinc, rust and oxide formation are also prevented. Moreover, a zinc roof is very durable, but also comes at a higher price point.

• Clean the roof twice a year.
• Never walk on the roof in high or low temperatures.
• A zinc roof covering can last up to 100 years with normal regular maintenance.
• Zinc is a natural material, meaning it can shrink and expand. Therefore, expansion joints are necessary when installing new zinc.
• Check any lead strips and/or facade connections periodically for defects.

• If too much water remains on the roof, there's a risk that the roof surface will flood or leak. A proper slope must always be maintained! If the slope isn't functioning properly, it may be easily corrected by installing spacers under the roof surface. However, repairing such a slope problem is usually not easy, and part of the roof will have to be dismantled and properly repaired.
  • Another option might be to install an additional drain at the deepest point.
  • Have an expert and experienced plumber carry out this repair work and advise you.
