Should I Have My Roof Powder Coated For Extended Lifespan and Durability?

Industrial metal powder coatings have been around for decades. However, most manufacturers use them on machine components and encasements. Its purpose is to extend the metal material's lifespan and performance by safeguarding it against moisture, corrosion, and other damages. If you're a homeowner wondering whether powder-coated metal roofs are available for you to use as your new or replacement roof, then you're definitely going to learn more about it here.

An alternative to powder roof coating is anodized and paint coating. These two differ in consistency and protective capabilities against powder roof coatings. Classic Metal Roofs has an excellent explanation on how all three works below.

Any roof, no matter the product type or color, is only a good one if it is durable and does not leak. Versatile and malleable, aluminum roofing is a wise, cost-effective option for your home. There are three good options for protecting metal roofing. Paint protects surfaces and adds color, but metal roofing is different from other materials. To protect the material from the elements and to visually enhance the result, metal roofing can be anodized, painted with liquid, or powder-coated.

Anodizing

Anodized aluminum roofing has a protective surface coating of aluminum oxide that is applied via an electrochemical process. Because it is durable and weather-resistant, anodizing is a common, effective, and long-lasting protection for applications like standing seam metal roofing. The thicker the anodic coating, the longer it lasts.

Anodized coatings may be dyed almost any color. They will also take on bronze overtones naturally due to a diffraction phenomenon the coating itself produces over time. Anodized metal does not lose its coating, which grows integrally from the base aluminum and thus neither peels nor flakes, permanently sealing the aluminum roofing underneath against the elements.

Painting

Painting or powder coating also protects and colors metal roofing. However, these paints and powders should be factory-applied rather than completed DIY. Of the many resin options, PVDF performs exceptionally well on metal roofing in harsh weather environments. PVDF-coated aluminum roofing generally outperforms anodized metal. It is not only resistant to extreme weather, but also to chemicals, UV light, flaking, and chalking. Also contributing to PVDF’s popularity is the nearly limitless range of color possibilities.

But, how exactly does metal roof powder coating work? The best way to know is to read a copy about powder coating specified for roof usage. Thermobond is one interesting powder coating brand. We aren't endorsing them, but we can say the ability to use them even on traditional roofing materials such as asphalt shingles and wood shakes is an interesting ability.

Schroer & Sons has an excellent discussion about this below.

ThermoBond is a special powder coat available on all our metal roofing profiles.  It is a revolutionary technology in paint-coating that helps metal roofing break free from the standard monochromatic appearance.  ThermoBond is a special powder coat which gives metal a natural, weathered appearance and texture.

ThermoBond is comprised of small chunks of tightly bonded paint.  Its unique texture allows us to blend various colors of paint into one coating.  The ThermoBond powder coat creates a variety of light and dark nuances giving it a perfectly weathered look for the life of the roof.  This combination makes the color options virtually endless.

Specific colors have already been combined to created several gorgeous, weathered mixes.  Some have the color of stone, others of vintage metal, and some others of weathered wood. We have a blend for every home. There are virtually 200 different color and finish combinations available on any one of our lifetime metal roofing systems.

TWO COLOR FINISHES:

With ThermoBond you have two finish options.  You can choose to have your metal roofing system sprayed to a consistent, uniform finish.  Or, you can choose to have your metal roof system hit with bursts of ThermoBond paint coat.  This second option allows the base coat to show through in some spots, giving the roof of your home that perfect aged look.

Lastly, metal powder coating aside from roofs is extensively used in preserving the strength and capability of structural and architectural steel. Metal Construction News has an excellent article that discusses its practicality and sustainability below.

Powder coatings are still considered a novelty by many contractors, and given the long experience and track record of liquid coatings it is considered safe to continue purchasing and installing liquid-coated parts.

The truth is that metal for construction has been powder coated for over 40 years, and technically the properties are every bit as good as liquid analogs.

Whether for aluminum façade profiles and panels, metal ceilings, lighting units, fencing and railings, or internal partitioning, there is a powder coating alternative, and a qualified job shop capable of coating the parts.

Properties

Powder coatings are essentially the same as liquids, containing polymers as the backbone, with pigments to give the color and special additives to give specific properties, such as lower gloss, textures, soft-feel or anti-yellowing. The difference is that in liquid paints these are dispersed in water or solvent, where for a powder coating they are in dry form, and become liquid through the application of heat.

Metal parts are coated by charging the powder electro statically and spraying it at the metal to form a thin layer. The metal parts then move through an oven at typically 375 F where the polymer melts to form a liquid, flows to make a smooth film, and reacts to form a 3-D network. (Continued)
