Additionally, this paint doesn’t adhere very well to some metals, so keep that in mind if you’re planning on using it for a metal surface.

The Difficulty of Painting Corrugated Metal Roofs
Corrugated metal roofs are becoming more and more popular, and are one of the most difficult surfaces to paint. The corrugations make it hard to get even coverage, and if you don’t use the right kind of paint, the finish can peel off quickly.
The corrugations provide a unique challenge because they create shadows and valleys that collect dirt and debris. When painting a corrugated metal roof, it is important to choose a paint that will adhere to the surface and provide protection from the elements. [1],[2],[3],[4]
When Would You Want to Paint the Metal Roof?
A metal roof should only be painted if it is necessary. If the roof is rusty, has bare spots, or is otherwise in need of repair, painting it can help to extend its life. Painting a metal roof can also be a good way to change the color of the roof to match the trim on your house or another building on your property.
Metal roofs are known for their durability, but even they need a little TLC from time to time. Painting is one way to extend the life of your metal roof and keep it looking its best. But with so many different types of paints on the market, it can be difficult to know which one is right for your roof.
In case of rust, it is best to remove the rust with a wire brush before painting. This will help the paint to adhere better and provide a longer-lasting finish. But as long as you use a paint of a good quality, you can paint over even the rusty surfaces.
If you decide to paint your metal roof, be sure to use a high-quality acrylic-based paint that is designed for metal surfaces. These paints will resist peeling and fading, and will provide protection from the elements. [2][3],[4]
Types of Paints for Corrugated Metal Roofs
There are three types of paint that can be used on corrugated metal roofs: silicon polyester, polyester-resin and fluoropolymer resin.
Polyester-resin
Polyester-resin paint consists of a polyester base and a resin binder. This type of paint is durable and can resist damage. It is also the cheapest option between all paint choices.
However, polyester-resin paint is more vulnerable to dimming, it won’t withstand the effects of direct sunlight well. So if you don’t want to repaint your roof after, it’s better to choose lighter colors, or another paint altogether/
This type of paint should be applied with a roller or a brush. It is important to get good coverage in the valleys of the corrugations, as this is where dirt and debris can collect.
Silicon polyester
This type of paint is made of a silicon-based resin and is the most common type of paint used on corrugated metal roofs. Silicone polyester paint is available in a variety of high-gloss colors, and can be either brushed or sprayed on.
This type of paint is durable and resists fading, chalking and peeling. The more silicone continents paint has, the more durable it will be.
Fluoropolymer resin-based paints
Fluoropolymer resin paint is the most expensive type of paint for corrugated metal roofs. But it is also the most durable and provides the best protection against the elements.
So it has a strong enough protection from peeling and fading.It is also the easiest to apply evenly, making it a good choice if you are concerned about getting an even coat of paint on your roof. However, because it is so durable, it can be difficult to remove if you ever decide to repaint your roof. [5]
Methods of Painting Corrugated Metal Roofs
There are three primary methods for painting corrugated metal roofs: spraying, rolling, and brushing. We will go through all three methods one by one.Before using either method, you will want to make sure that your roof is clean before you start painting. Any dirt or debris on the surface will prevent the paint from adhering properly. You can use a pressure washer to clean the roof, or you can do it by hand with a stiff brush.
By using a brush
The most common method for painting corrugated metal roofs is by using a brush. It is the most recommended way to paint since it gives you more control over the process and it gets into the ridge sections easily enough. When using a brush, start from the top and work your way down. overlap each stroke so that you don’t miss any spots.
Also, make sure to clean the brushes after each use so that they last longer.
One downside of painting with a brush is that it can be time-consuming. If you have a large area to cover, it might take several days to finish the job.
Another downside is that it can be difficult to paint evenly with a brush. If you’re not careful, you might end up with streaks or brush marks in the paint.
By using a roller
Rolling is also an option of painting a corrugated metal roof. But due to the structure of the corrugated roof, it may not paint all the surface without additional effort. For that you will need a profiled roller.
Start painting over the clean roof. Begin at one end of the roof and work your way down in overlapping strokes. Be sure to keep a wet edge to avoid creating any lap marks.
By using a spray gun
A paint sprayer is the fastest way to paint a corrugated metal roof. It will also give you the best coverage. We recommend you to use an airless paint sprayer for this job. Airless paint sprayers pump the paint directly from the canister through the hose and nozzle. This type of sprayer is less likely to clog than other types of paint sprayers.
Set up your airless paint sprayer according to the manufacturer’s instructions.
Start by spraying the edges of the roof and then work your way in towards the center. Overlap each stroke by about six inches to ensure that you have full coverage. [6]Once you have finished painting, be sure to clean your asprer to make it last longer!
How to Paint Your Roof
Now, let’s see how you can actually paint your roof. This is a pretty straightforward process, but there are a few things you need to keep in mind.
The type of metal
Galvanized steel for example won’t give you the best results as paint adheres badly to such kind of metal. So it’s best to double check if your roof can be painted, you don’t want to waste all that effort.
Collect the tools and materials
You will need a ladder, power washer, wire brush, primer (zinc chromate or galvanized), and paint (acrylic latex). Also make sure you have drop cloths to protect the area around your work space. [5]
Preparation
Remove old paint layers if there are any
The first step is to remove any old paint layers from the roof. If you’re working with a new roof, you can skip this step.
Use a scraper to remove any loose paint or rust. If there are any stubborn areas, you can use a chemical paint stripper. Be sure to follow the manufacturer’s instructions carefully. Removing mold will require the use of chlorinated bleach solution. [1],[2],[3]
Clean your roof
Next, you need to make sure that the surface is clean and free of any debris. If there’s any dirt or grime on the surface, it will prevent the paint from adhering properly. You can use a pressure washer to clean the surface, or you can just scrub it with a brush and some soapy water. Be sure to remove any rust or mildew before painting.
After the surface is clean, you need to rinse it off with clean water. You don’t want any soap residue on the surface when you paint. [1],[2]
Use metal degreaser
Once the surface is dry, you need to treat it with a metal degreaser. This will help the paint to adhere better and prevent rusting. The recommended choice for this is a TSP mixture.
Apply the degreaser according to the manufacturer’s instructions and let it sit for the recommended amount of time. Then, rinse it off with clean water.
Once the surface is clean, you’ll need to prime it before painting. This will help the paint adhere better and also give you a better finish. You can use an oil-based primer or a latex primer for this purpose. Just don’t forget to use a protective tarp when you’re painting. [1]
Painting
Now that you know how to prepare your roof for painting, it’s time to actually start painting it!
Read the instructions first
Prepare a protective tarp and read the instructions on the paint can before beginning. This is important because every paint is different and you need to know how to apply it correctly.
Paint the first layer
Once you’ve read the instructions, begin painting from the top of the roof and work your way down. Be sure to use a brush or roller specifically designed for metal surfaces. If you’re using a sprayer, be careful not to overspray and create a mess.
Paint the second layer
After the first layer has dried, you can apply a second coat if necessary. Again, start from the top and work your way down.
Let it all cure
Once you’re finished painting, let the paint cure for the recommended amount of time before walking on the roof or exposing it to weather.
After you finish painting, it is important to maintain your roof and keep an eye out for any paint chipping or peeling. If you see any problems, be sure to address them right away.
Clean your roof half a year or so to prevent any dirt or grime from building up and affecting the paint job. [1],[2]
Safety and General Tips for Painting the Roof
Consider the weather
When you’re painting, it is important to consider the weather. If it’s too hot or too cold, the paint can crack. The ideal temperature for painting is between 50 and 90 degrees Fahrenheit.
If it’s not possible to paint during these conditions, you can still proceed with the project but be aware that there may be some issues.
In hot weather, try to avoid painting in direct sunlight if possible. This will help the paint to dry more slowly and prevent any problems.
In cold weather, make sure that the surface is completely dry before painting. If there is any moisture on the surface, it can cause the paint to crack when it dries.
It’s also a good idea to avoid painting during windy conditions as this can make the process dangerous.
Use protective gear
When you’re painting, it’s important to wear the proper protective gear. This includes gloves and goggles.
The paint fumes can be harmful if you breathe them in, so it’s important to wear a respirator mask as well. You should also avoid wearing loose clothing or anything that could get caught on the roof. Wearing the proper protective gear will help to keep you safe while you’re working.
Be careful while moving on the roof
When you’re painting, it’s essential to be careful while moving on the roof. Make sure that you’re always aware of your surroundings and take care not to step in any puddles of paint.
If possible, it’s best to use a ladder or scaffolding instead of walking on the roof itself. This will help to prevent any accidents. In general, just be careful while you’re working and take your time. Rushing can lead to mistakes being made which can put you at risk.
It’s important to choose the right footwear when you’re painting the roof. Wearing shoes with good traction will help to prevent any slips or falls.
In addition, it’s a good idea to avoid wearing open-toed shoes or sandals. If you do get paint on your skin, be sure to wash it off immediately. [1],[2],[3],[4]
Buyers Guide for the Best Paints for Corrugated Metal
No matter what type of paint you are looking for, there are a few things you should keep in mind when shopping for the best paints for corrugated metal. Here are a few factors to pay attention to when choosing a paint for our roof.
Price
The price of the paint is, of course, one of the main concerns for most people. You want to make sure you are getting a quality product without spending too much money.
There are a few ways to save money when buying paint. One way is to buy in bulk. If you know you will need multiple cans of paint, it can be cheaper to buy them all at once. Another way to save money is to look for sales or discounts. Many stores have seasonal sales or offer discounts for loyalty programs.
Another factor to consider is the type of paint you need. Some paints are more expensive than others because they provide better coverage or last longer. If you are painting a small area, you may be able to get away with a cheaper paint. However, if you are painting a large area, it is worth it to spend the extra money on a higher quality paint.
Finally, don’t forget to factor in the cost of other supplies you will need, such as brushes, drop cloths, and primer. These items can add up quickly, so be sure to factor them into your budget when shopping for paint. [1],[2]
Cure time
Cure time is the amount of time it takes for a paint to fully dry and set. This is important to pay attention to because you don’t want your paint job to be ruined by rain or snow before it has had a chance to properly cure.
If you are unsure about how long your chosen paint will take to cure, be sure to ask a sales associate or look up the information online. [2],[3]
High adhesion rate
Another factor that you should keep in mind is the adhesion of the paint. Corrugated metal can be a difficult surface to paint, so it’s important to choose a product with a high adhesion rate. This will ensure that the paint sticks to the roof and doesn’t peel or chip over time.
Another thing to consider is the type of metal roof you have. If you have a galvanized steel roof, then you’ll want to choose a paint that is specifically designed for that type of metal. Paints that are made for other types of metals may not adhere as well to galvanized steel and could end up peeling or flaking over time.
Corrosion Resistance
When it comes to choosing the best paint for corrugated metal, one of the most important factors to consider is how well the paint will resist corrosion. Corrugated metal is especially susceptible to corrosion, so it’s important to choose a paint that will protect your roof from the elements. Look for a paint that is specifically designed for use on metal surfaces, as these paints typically contain corrosion-resistant ingredients. Additionally, check the product label to see if the paint is rated for exterior use – this will ensure that it can withstand the harsh weather conditions. [3],[6]
Color of the paint
Of course, the color of the paint is one of the most important factors to consider when choosing a paint for your corrugated metal roof. You will want to choose a color that compliments the overall look of your home. If you have a light colored house, you may want to choose a light colored paint for your roof. Conversely, if you have a dark colored house, you may want to choose a dark colored paint for your roof.
It is also important to choose a color that will reflect heat, as this can help to keep your home cooler in summer months. Light colors are typically the best choice for this purpose. [1],[5]
Consider the Finish
The finish of the paint is also an important consideration. If you want a paint that will last for many years, you will want to choose a paint with a high-quality finish. Some of the best finishes include acrylics and urethanes. These finishes are durable and will resist fading and chipping. [1],[3]
How Easy It Is to Apply
Another important consideration is the ease of application. If you are not experienced in painting, you will want to choose a paint that is easy to apply. Some paints require a primer before they can be applied, while others do not. You will also want to consider how many coats of paint you will need to apply. The more coats required, the more time and effort it will take to complete the job. [1],[2]
Toxicity
Some paints contain toxic chemicals that can be harmful to your health. If you are concerned about toxicity, you will want to choose a paint that is low in VOCs (volatile organic compounds). These paints do not release harmful fumes into the air and are safer for both you and the environment.
Usually, these paints are more expensive than their counterparts, but they are worth the investment if you want to protect your health.
But it’s still a good idea to apply paint in a well ventilated area and use a respirator to avoid fumes. [1],[2]
Resistance to UV light
One of the most important things to consider when choosing a paint for your corrugated metal roof is how well it will resist UV light. The sun can be brutal on any type of paint, but it’s especially tough on lighter colors. If you want your paint job to last, make sure you choose a product that is designed to resist fading and other damage from the sun. [1],[6]
Elasticity to deal with extremes in temperature
The best paints for corrugated metal roofs need to have some elasticity to them. This is because corrugated metal roofing can expand and contract due to changes in temperature. If the paint is too rigid, it will crack and peel under the stress of these temperature changes.
Additionally, you’ll want to make sure that the paint can withstand high temperatures. This is especially important if you live in an area with hot summers. The last thing you want is for your paint to start peeling and bubbling after just a few months!
Coverage rate
The other thing you’ll want to consider is how much coverage you need. If you’re painting a small area, you can probably get away with a lower-coverage paint. But if you’re painting a larger area, or if you want to make sure your paint job lasts for years, you’ll want to choose a high-coverage paint. It depends both on the capacity of the paint and on the price you’re willing to pay. [1]
Longevity
When it comes to paints for corrugated metal, one of the most important things to consider is how long the paint will last. You want a paint that is going to withstand the elements and last for years to come.
Most paints can last for several years if they are properly applied and maintained. However, some paints are better than others at resisting fading, chalking, and other wear and tear. If you want a paint that is going to last for a long time, look for one that is specifically designed for metal roofs.
One thing to keep in mind is that even the best paint will eventually need to be replaced. How often you need to repaint will depend on the quality of the paint and how well it holds up against the elements. [2],[6]
