If the goal is to have your home or buildings make an architectural impact, then moving beyond ordinary roofing materials and practices is a must. In areas where traditional asphalt shingles dominate the roofing market, switching to a metal roof can often make a statement. To take metal roofing to the next level, zinc is the clear choice.
Metals can be broken down into two categories: natural and painted. In this article, I’ll be highlighting natural metals – specifically zinc. Natural metals are either pure or alloyed and weather according to the environment in which they’re exposed. Often considered a “living” material, zinc forms a protective outer layer, or crust, called the ‘patina’. An interesting fact about zinc is that it’s a ‘self-healing’ material – that’s right – it heals itself when scratched by forming (or re-forming) the patina through wetting and drying cycle, so that the scratch blends, and eventually disappears.
This image above shows the patination process under 30 times magnification. It can take 5 months to 5 years for a roof to patina and will depend on the micro-climate that it resides.
What contributes to zinc’s overall appeal?
- It’s (very) long-lasting; when properly installed, a zinc roof can last 80 years.
This church above, in Reutlingen, Germany only needed a partial re-roof after 120-years of service. Click on the image for the full story.
- It’s low-to-no-maintenance.
- It’s environmentally friendly; and infinitely recyclable – without loss of properties and, unlike other roofing materials, zinc will not end up in a landfill.
- Its unique ability to look great on any type of architecture: from Traditional to Modern and everything in between.
Both images are homes with standing seam roofs in prePATINA blue-grey – same application; very different looks.
It shows that as the Homeowner, Architect, Designer, etc. – that you’ve done your homework on quality roofing materials.
Zinc roofing can provide an architectural aesthetic that few other materials can achieve.
