Can You Paint a Metal Roof? – Top Tips
Most homeowners spend much time perfecting every nook and cranny on their property. They buy a house, remodel, furnish, and decorate it, and then spend years enjoying the fruits of their labor. However, few things in life are eternal, and there comes a time when you need to remodel again.
Today, we will discuss roof remodeling, specifically metal roofs. We’ll discuss whether such a project is possible (spoiler alert: it is), why people choose this option, and the benefits of a painted metal roof.
This blog post will cover everything you need about painting metal roofs. Let’s get into the details.
The Overall Feasibility of Painting a Metal Roof
We already spoiled it for you. Can you paint a metal roof? Yes, you can, but there are a few things to consider. We’ll list them below and discuss some of these points in more detail later.
- If your roof is new, you should wait six months before painting it.
- If it’s old, check whether it needs repairs. The roof must be properly repaired before you begin.
- You need to clean the entire surface. You can use any biodegradable cleaner mixed with water to ensure the roof is 100% clean. Then, just let it dry thoroughly.
- Use sandpaper to remove any rust, but clean all the debris afterward.
- Select a quality metal primer and apply it to the entire roof before repainting. Check the store to ensure the primer is suitable for metal roofs.
- Get the correct paint. You can use oil-based or acrylic paint. Check whether the paint is suitable for metal roofs and compatible with your chosen primer.
- Look at the weather forecast. You don’t want rain and don’t want it to be too hot or cold outside.
So, we know the considerations. Now, let’s explore the benefits.
The Main Benefits of Painting a Metal Roof
There are four main benefits of painting a metal roof.
Prolonged lifespan of your roof
After a proper repainting job, your roof will be as good as new. This way, you reset the clock and prolong the roof’s lifespan. It will be nice and shiny for a long time.
Improved energy efficiency
When you repaint and repair your roof, you can expect enhanced energy efficiency and lower air conditioning costs. After some time, the roof itself will pay for the repair.
Enhanced protection
A new roof color will protect against rust, wear and tear, and UV rays. And if this isn’t enough, there is a fourth benefit.
Improved aesthetics
Last but not least, we have another significant benefit. A new roof color will add aesthetic appeal and update the entire look of your home.
It’s time to get our hands dirty. Let’s talk about how to prepare your metal roof for painting.
Phase 1 – Preparation
The preparation phase is the most important one. That’s why it comes first. If you want to do a good job with anything, you must prepare adequately. When painting your existing roof, there are three things to check. Let’s dive in.
Assessing the roof’s current condition
Check the entire roof surface for signs of rust, dirt, corrosion, and old paint. Also, check your power lines for irregularities. Finally, check your roof’s warranty document. Some issues might be fixed if you are still under warranty, but some actions might void your warranty, so pay close attention.
Cleaning the roof’s surface
You will need heavy machinery to wash your roof, such as a pressure washer or power washer. If you see rust, use sandpaper to even everything out. You can use a diluted vinegar solution to clean the roof further and remove debris.
Choosing the right primer
As mentioned, you can ask your local supplier for help choosing a primer. However, there are a few things you should know beforehand. First, look for a galvanized metal primer which offers the best results. Second, properly determine whether your roof is bare or corrugated, and pick the primer accordingly.
Choosing the right paint
There are three different types of paint for your metal roof.
- Acrylic latex paint – Energy-efficient and durable, it’s an excellent choice, but a more expensive one.
- Oil-based alkyd paint – Suitable only for specific surfaces. Check with your supplier before purchasing.
- Direct-to-metal (DTM) paint – A good choice if you live in areas with extreme weather conditions, as it is ideal for weather resistance.
You should know if the roof surface material is a standing seam, corrugated metal, or something else. Also, your location plays a significant role. What are the weather conditions in your area?
How much sun exposure do you have? All this information influences your decision to purchase what type of paint. Share this information with your local supplier and explore your options.
Phase 2 – Painting
Now that the preparation phase is complete, it’s time to get to work. We will provide a clear, step-by-step guide on how to paint your metal roof.
- Step 1: Apply the primer – Apply your chosen primer evenly across the entire surface of the roof. This will help improve the roof’s brightness, and the final version will look much better after painting. You cannot paint the metal roof properly without applying the primer beforehand, so it’s a crucial step. Check the manufacturer’s instructions to see how long the primer needs to dry.
- Step 2: Apply the first coat of paint – You can apply the first paint coat when the primer is thoroughly dried. There are many methods for this. You can use a brush or a roller, but the best option is spray painting. It will help you paint everything evenly. When you finish applying the paint, let it dry.
- Step 3: Apply the second coat of paint – Check the instructions for the paint you bought. Certain products require only one coat of paint, but others require two. If your chosen paint requires two coats, apply the second one when the first one dries fully.
After you are done, you can take a few steps back and marvel at your work.
How Much Will All This Cost?
We can now move forward with finances.
You can tackle this project alone or with a friend if you have all the required machinery. The costs will be significantly lower, but it will take longer. Also, consider the risks. If you are not a professional, you will undoubtedly make mistakes. This will set you back, you will waste time, and your costs will increase.
If you feel confident that you can DIY it, the total costs should be $200–$500, depending on the size of your metal roof and the materials you need to purchase.
The price of hiring a professional will depend on the size of your roof, but you can expect a 70% increase in costs compared to the DIY approach. Generally speaking, the price can be between $1000 and $3500.
Should this be a DIY Project, or Should You Hire a Professional?
- Well, this is a tricky question, and the answer depends on your skills as a handyman or woman. Are you someone who tackles home repair projects on a regular? Do you have a bunch of expensive tools in your shed? Do you know your way around a pressure washer?
- If the answer to everything is yes, you should go the DIY path.
- If the answer is a resounding no on all points, you should seek professional help. This option is good because you don’t have to be home and can avoid all the mess and noise.
- Those who answered yes and no might want to find a compromise. Contact professionals for a consultation to determine your best course of action.
- It’s worth mentioning that seeking professional help involves a lot less risk. If you do everything yourself, you risk getting injured (or worse).
Maintenance Tips
When you finish the project, you might think that your job is done and will be correct to a certain extent. Yes, your repainting job is done, but maintenance comes next.
Regularly inspect your roof for signs of wear and tear and corrosion, so if you notice anything, fix that spot instantly. Periodically repainting to maintain energy efficiency and prevent further damage is a surefire way to prolong the lifespan of your metal roof.
