Whether you’ve recently bought a property with a metal roof or wish to change the color of your existing roof for the sake of aesthetic and energy efficiency, painting the metal roof naturally stands out as the most logical solution for the sake of your time, finances, and commitment to living an Eco-friendly life.
The short answer is: yes, you can paint a metal roof. However, if you wish to change the color of an existing metal roof, it’s imperative that you do it in the right manner. Here’s all you need to know.
When Can a Metal Roof be Repainted?
All types of metal roofing are suitable for repainting, but it should be noted that newly installed metal roofs should not be changed for at least six months as they need time to weather.
Before painting a metal roof, though, you must also prepare it for the process ahead by removing mildew, dirt, and any loose paint that may be left over from the original paint job. A jet power wash is the best way to achieve this, and can complete the task in a matter of minutes.
When you want to change the color of an existing metal roof for the first time, using a diluted vinegar solution to remove any old paint oils and residue is a wise move too.
How to Repaint a Metal Roof
After preparing the metal roof through a power wash treatment, you need to ensure that the right processes are used to paint the roof. First and foremost, the right type of paint should be selected.
Acrylic latex paint works well for bare metal roofs or painting over old paint coats. The combination of oil-based alkyd paint and a galvanized metal primer can work well too, ensuring that the paint is locked in and adhered in the right manner. With so many brands on the market, it’s important to look for a paint that offers the attributes you require. Water resistance, fire resistance, insect repellent capabilities, and UV reflection are all properties you may seek.
Application is a relatively simple task. You can use a sprayer to reach high or steeped metal roofs. Alternatively, rollers and paint brushes that are designed specifically for corrugated metal are equally capable of providing the quick coverage you crave. Only a few coats are needed, although you can usually judge this for yourself.
If all else fails, or you’re worried about safety (you should wear a harness and non-slip shoes), you can always hire a professional to repaint metal roof solutions on your behalf.
The fact that metal roofs require minimal maintenance is a very attractive feature, and is another reason for staying loyal to this material. Nevertheless, a little work can help extend the life of your roof by several years.
Cleaning the roof once every six months with a gentle detergent should suffice. It removes debris and dirt before it has a chance to penetrate the paint or make the metal start to rust. It also provides an opportunity to identify and treat bald spots or any other early signs of damage.
You may still wish to repaint the roof once every few years to maintain the fresh look, but you’ll no longer need to worry about replacing the roof. Perfect.
