5 things to know about Kynar 500 for metal roofing
Kynar 500 is a great product for standing seam metal roofing. However, some may think getting cheaper panels with a different coating to save some money is worth it.
Before even considering that, it's important to know some things about the number one painted finish in residential roofing.
1. Kynar 500 protects the metal panels
The biggest things that Kynar 500 does for metal roofing is that the coating actually protects the metal panels. Metal rusts after prolonged exposure to the elements, which would be terrible in some areas of the United States.
So, Kynar 500 protects the from the wear and tear a roof experiences as the years go by. In fact, the painted finish is a huge reason why a metal roof lasts as long as it does.
2. Kynar 500 slows down color fading
Kynar 500 provides the metal panels their color when applied. However, the elements and direct sunlight affect metal roofs and all roofing materials, including causing the color to fade.
The great thing about Kynar 500 is that it's specifically made to resist the breakdown, slowing down the color fade as the roof ages. So, you get a color that matches your home's aesthetic and a formula that doesn't fade as quickly as other roofing materials all in one.
3. Kynar 500 has reflective properties
Metal roofing already has some reflective properties, but the Kynar 500 painted finish can boost it to over 70%. This means the roof surface stays cooler by not absorbing heat, which keeps the rooms below cooler.
This is a huge reason why metal roofing is considered an energy efficient material. There are even "cool" metal roofing panels that are made with reflective properties, especially in areas that see a lot of direct sunlight and high temperature.
Recently, Kynar 500 has been applied to these panels, boosting the reflective properties even more.
4. The Kynar 500 painted finish must be protected during installation
A huge part of correctly installing a metal roof is protecting the Kynar 500 painted finish on the metal panels. If there’s any scratching or other damage to the finish, the fresh steel on the metal panels is exposed to dew or moisture in the air, causing them to rust.
Unused cuts, little triangles, or any type of shavings can't be left on the roof because the steel will literally rust overnight. This leads to problems and shortens a metal roof’s lifespan.
5. The paint warranty that comes with Kynar 500
Unlike asphalt shingles, metal roofing comes with a warranty on the painted finish instead of the panels. Kynar 500 comes with a 30-year warranty on the painted finish itself that's applied to the metal roofing panels.
This warranty covers the color of your metal roof if it fades too soon or if the metal is damaged related to problems with the painted finish (scratches, rusting, etc.). The great thing is that once the paint gets past 30 years, it doesn’t mean just disappear.
It just means that after the paint warranty expires, you should start budgeting to replace your standing seam metal roof.
And once you see a lot of rust or the color is extremely faded on your metal panels, you should start the process of replacing your standing seam metal roof.
What else do you need to know about metal roofing?
Now you know that the Kynar 500 painted finish is important to keep your metal roof’s color from fading and protecting it during its lifetime. As long as it’s installed correctly and the painted finish is protected, you should get decades worth of protection.
It should even outlast the 30-year paint warranty. However, the painted finish applied to the metal panels isn't the only thing you need to know about metal roofing.
A new metal roof is a large investment that's out of most budgets. So, I want you to have all the information you need to decide if metal roofing is worth it for you.
