The Buzz About Zinc
Looking for a metal roofing material option that’s both beautiful and long-lasting? You’d be hard-pressed to choose anything better than zinc! If you live in the U.S. you may not have considered zinc before since it has yet to gain tremendous popularity in these parts, but here’s a fun fact – 70% of all European residential roofs are covered with zinc metal panels. Now, just because Europeans do something does NOT mean that Americans will, or even necessarily should, follow suit. This is America, and ain’t NOBODY gonna tell us what to do! But still, zinc does carry lots of distinctive features, so we would be remiss if we didn’t discuss its pros and cons, along with some good zinc alternatives.
Advantages and Drawbacks Where Zinc Is Concerned
So, is zinc something that should be on your radar if you’re planning for a metal roof? Let’s do a quick run-down through some of zinc’s pros and cons.
If you’re looking for a roof with some real longevity, this is one of zinc’s real selling points. Zinc panel roofing commonly lasts 100+ years. The only other common material with a comparable lifespan is copper.
Another similarity zinc carries to copper is the fact that it creates its own unique patina through oxidation. This patina layer helps to protect the zinc, and small scratches on the zinc will actually fill themselves in over time.
Another great thing about zinc’s patina is the distinctive & attractive appearance it creates. Zinc can start out as a dark shade of grey, and then over time it will change to a lighter grey, and can take on a more bluish tone.
Essentially No Maintenance
Once the zinc goes on your roof, there’s very little you’ll ever need to do to it. The patina renews itself, so aesthetic repairs shouldn’t ever be necessary. As long as it’s installed right the first time, zinc needs little to no maintenance.
Conserves Natural Resources
Zinc is a metal that’s 100% recyclable and can be reused over and over. Zinc also requires less energy resources and fewer carbon products to produce than some other popular roofing materials, like shingles.
One of the biggest disadvantages to zinc as a roofing material is its cost. In comparison with most other roofing materials, zinc does carry some sticker shock. In fact, the only common roofing material that’s more expensive than zinc is copper. This may really be one of the main reasons why zinc has yet to catch on in U.S. markets.
Patina Process Can Be Slow & Hard to Predict
Many people like the patina appearance, but one issue with patina is the fact that you can’t really predict what your actual patina will end up looking like. If you have one specific color tone you’re going for, then zinc patina may not be your best option. Zinc patination can also be a slow process – it can complete itself in as fast as 2 years, or in some situations it can drag out for closer to 30 years!
Risk of Improper Installation
Poor installation practices are a danger for any roofing material, but the stakes are a little higher when it comes to zinc and other metals. If water is given a chance to intrude behind or beneath the metal paneling, moisture can get trapped inside, and can end up doing extensive damage to the entire roof system.
What’s Good About Metal Roofing in General
While zinc may or may not be the best choice for your particular situation, there really are many reasons to choose a metal roof in general. Here are just a few:
Metal roofs are built to last
As long as you choose quality materials and have them installed properly, a metal roof really can be the last roof you’ll ever need!
Wind, lightning, & fire resistance
Some metal roofs have been rated for wind gusts of 140+mph. Metal also won’t burn, so it offers better fire protection, and metal is better suited for dissipating the impacts of a lightning strike than other materials.
Won’t rot or host mold & mildew
Metal doesn’t rot, and won’t corrode if it’s treated properly. Metal also plays a poor host for mold and mildew growth.
Works on roofs of any pitch
Whether your roof is steep or has a relatively low pitch, metal can be a good solution for your roofing needs. Most other roofing materials aren’t nearly as versatile in their application potential.
Looking for a More Affordable Zinc Alternative? How About a Metal Roof with Zinc Patina?
Not sure you’re ready to pull the price trigger on a zinc roof, but like the look of zinc? Then it would be worth your while to consider a galvalume steel roof painted with a Kynar zinc patina! A galvalume steel roof can easily last you from 40-60 years with little-to-no maintenance, it includes its own warranty, AND it’s more affordable than zinc. Kynar 500 resin-based coatings are infused right into the metal, and they retain their color tone and gloss much better than other metal paints. Another advantage of going this route is that you can choose the exact patina look you want, without having to worry about what the final result of a natural zinc patination process will end up looking like.
