Patinated zinc roof.
As you may have guessed zinc is extremely durable.
Galvanized and galvalume steel will forgo that aging for a couple of decades.
For what its worth thanks to the self healing aspect of zinc once it has fully undergone its patination there is an established market that sells pre patinated zinc roofing.
Materials like copper and statuary bronze are well known for developing dark browns and greens on their surfaces.
Quinta metálica was the first installer in spain to work with this new range of patinated zinc in blue tones.
When steel is galvanized it is really just adding a protective layer of zinc to dteel base to protect it from oxidation as steel is naturally corrosive or will rust when exposed to salt water or moist environment over a long period of time.
Most metal roofs will last at least 35 to 50 years because well it s metal.
Currently rheinzink is the only manufacturer with a type 2 designation.
Patina is a word describing the oxidization layer which builds up on metal surfaces.
This means that any scratches on the surface will recover on their own over time says trevor.
Zinc can also be chemically patinated to develop protective patina coatings in a wide range of color.
Providing your roof is properly installed and detailed zinc could offer a service life of between 60 and 100 years says trevor corser from jtc roofing contractors.
If the idea of your roof changing its color overtime is not appealing to you then pre patinated zinc roofing panels may be the way to go.
This is one of a few reasons why the market for zinc will often sell pre patinated zinc roofing.
Type 1 is for bright rolled and blue grey zinc and type 2 is for graphite grey zinc.
Rheinzink conforms with astm b69 16 type 1 and type 2 for architectural rolled zinc.

Durability is an important benefit.
Zinc roofs are extremely corrosion resistant too and unlike other metal roofs they are self healing.
A lesser known but aesthetically rich material for patination is zinc.
