Ultimate Buyers Guide For Best Metal Roof Paint

Before you decide on which paint to buy, you need to keep some factors into consideration. These factors determine which is the best paint for metal roofs. We discussed briefly on these points below.


Versatility is an issue you need to consider because this is the mark of good quality paint. Any paint that sticks on to a variety of surfaces is durable and lasts long enough to give back its worth.


When you’re painting your roof, you have to consider the weather as a big factor. And fluctuation of the temperature affects the shape of the roof. So, if the paint isn’t flexible enough to expand and contract with the roof, then it won’t last long. Tearing up will be an issue.

Color of the Paint

The color matters mostly due to the absorption and reflection properties. Darker colors hold in heat which in turn heats the roof. Therefore, if you’re looking to cut down on the energy bills in colder countries, this is a good option. Light colors on the opposite reflect heat.


Protection from UV rays and damages are needed for roofs as it goes through so much of the outdoor environment. Anything and everything might drop on it and scratch it, which will damage the surface of the coating if it isn’t strong enough.

Prevention of color loss is also an issue. Check the reviews from users to get good knowledge about it.


Good quality paints are waterproof. But there’s a certain amount of heavy coats needed to be applied on the roof to get the best result. Follow the manufacturer’s advice on how to paint galvanized sheet metal roofs and how many coats your specific paint requires. It depends on the thickness.

Area Coverage

Paints can cover 30 sq. ft. to 300 sq. ft. per gallon, depending on its components. The more, the merrier, but it’s up to your choice if you want it thin or thick.


You need to consider the weather temperature that paints need to dry. Generally, warm temperature of 60°F is recommended.

Drying Time

Not every paint dry in the same period. Some are quicker than others. Those paints that dry quickly are recommended as you don’t need to consider the forecast as much as you need for paints that take a whole day or more for drying up.

House owners usually make some common mistakes while painting metal roof. Hope you will not make those mistakes.
