The Best Paints for a metal roof

Metal roofs are preferred for their longevity and best value. But at times, the metal roofs can get old, rusty, and unpleasant. This does not mean there are serious structural issues; the metal roof can be repainted to make it look better. Repainting is always seen as a cheaper option for face lifting a roof, but it also comes with unique challenges. Most of the common issues that most people face are whether to go for exterior paint or metal roof paint. And if so, the best color for the metal roof.

What’s the difference between roof paint and exterior paints

Thou both are used on the exteriors; there is a vast difference between metal roof paint and exterior paint. The two should never be mixed, nor should they be mistaken as their functions and capabilities are distinct. Roof paints, especially for metal roofs, are superior as they have advanced cooling capabilities, are waterproof, and last longer than exterior paints. Here is a closer look at the difference between roof paints and exterior paints;


When a homeowner decides to buy paint, they intend to have the color serve them for a long while. Exterior paints usually last anywhere between 7 to 10 years, while roof paints will go for 15 years. The difference is quite extensive, which makes roof paints quite enticing to many homeowners.

UV absorption

The sun releases UV, which can be pretty damaging to metal roofs. But most paints are designed with elastomeric resins, which have UV absorbing capabilities. This is vital in preventing the UV rays from harming the metal roofs. On the other hand, exterior colors have no such thing as this, which means your metal roof will not last for a long time.


Designed to withstand the pressure that metal roofs face, roof paints have superior quality to exterior paints. When exterior paints are exposed to harsh weather, they tend to peel, crack and chip because they are not elastic. On the other hand, Roof paints are meant to be elastic, which makes them accommodate the expansion and contraction of metal roofs.


Generally, exterior paints are somewhat cheaper than roof paints. Since roof paints have more enhanced features, which enable them to outlast exterior paints, the cost is also different. But, there is a catch; the cheaper option can prove costly as exterior paints tend to have a shorter lifespan. Readout more about metal roof coating costs at Home Garden Guides.


Energy efficient

Since roof paints are applied on the top side of the house, they are crafted with better energy efficiency. Most, if not all, metal roofs have highly reflective ceramics, which pushes the heat away from home. The roof paints are designed to reflect the heat into the atmosphere rather than retain the heat. This is something that’s not possible with exterior paints.
