Primer For A Metal Roof
Before applying the primer and the paint, you should check the weather forecast to make sure no rain is expected in the forecast for a day or two. An unexpected rain shower can wreak havoc on your roof painting plans!
The primer you select for your metal roof should be a product that is designed specifically for metal the type of metal roof you have. Galvanized metal requires a different primer to non-galvanized metal. Your local hardware or paint shop will be able to advise you on the best product to select.
Apply the primer using one of the rollers, using the telescoping extension to reach the far reaches of the roof. You will only need to apply a single coat of the primer, but make sure the coating is thick. Cover the entire metal roof with primer and give it at least one hour to dry before applying the paint.
Painting In The Wrong Weather Condition
Another condition that is overlooked is the weather forecast for when youre planning on painting your metal roof.
Ideally, the best time to paint your roof is either during spring or fall. The weather conditions during these times are cooler and you can expect little to no rainfall. In order for the paint to cure you will need around a day or two of no rainfall- which means you will have to look at the weather forecast.

Material Choices For Metal Roofing
The advantages of metal roofs such as resistance against a hurricane, energy conservation, and durability are gravitating many people to install them on their roofs. There are a lot of materials commercially used to make roofs. We are listing some of them for the help of people intending to install a metal roof in the future.
Steel
This is one of the most famous material and most robust materials that you can use for metal roofing. It is also one of the less expensive options. Commercially, steel is galvanized to prevent rusting. Alternatively, coating it with aluminum-zinc also happens.
Aluminum
The aluminum roofs are always painted. They are a little pricier and softer than steel. Aluminum is most suitable for areas that experience acid rain because of its rust-resistant properties.
Copper
Copper is another material commonly used for roofing. It has the longest history of use as a roofing material. It is the most expensive and long-lasting material which is easy to cut and shape. The material can last as long as two centuries. Over time it develops a protective coating that turns blue.
Terne
The tin-and-lead-coated roofs were first used in 19th century Europe. It is frequently painted to protect its iron substrate. In modern times, steel roofing with layers of tin is common to resist extreme weather.

Maintain The Painted Roof
Youre not done yet! The baked on finish from the factory is designed to last maintenance free. But thats not true when you repaint a metal roof. Every six months you will want to get up on top of the house and wash it with a mild detergent. Remove debris, clean off gunk, and make sure that the paint isnt chipping, peeling, or otherwise detaching from the roof. Its quite a bit of work, but the finished product can be worth it.
How Much Does It Cost To Paint Roof Shingles
The cost of painting your roof shingles will depend on the paint that you buy, how big your roof is, and whether you are painting it yourself or hiring professional house painters.
One gallon of exterior roof paint usually costs between $25 and $30 and covers about 450 square feet. The number of gallons you need will depend on the surface area of your roof.
Besides the paint, you will need other supplies for painting your roof, including primer, rollers, and paint trays.
Dont forget to buy safety equipment that will help you reach the roof and prevent you from falling, such as ladders and harnesses.
All the supplies for painting your roof may cost you $500, and thats not even counting the hours of lost work spent painting your roof, or if you have to repair any mistakes later on.
If you hire professional painting contractors, it will be more expensive to paint your roof. They usually charge $2,500 to $4,500 per roof, depending on their price levels and the size of your roof.
Before committing such a large amount of money to your roof, ask a couple of different contractors in your area for quotes to find the best deal.

Best Metal Roof Cleaning Products
PLAIN WATER
Dirt, dust, and other low-grade elements might wash off a roof with something as simple as water from a hose. Feel free to use as much water as necessary until the surface is clean.
DETERGENTS
This is the cleaning solution that most people need to use when cleaning their metal roof because its non-invasive and easy to do. This category includes mild laundry detergents, car washing soap, mild dish soap, and cold or hot commercial/industrial detergents.
SOLVENTS & PETROLEUM SOLVENTS
Solvents can be used to remove the tougher non-water elements that could come in contact with your PVDF-coated roof, such as oil, paint, grease, tar, and even some graffiti, according to Valspar. Solvents should be used to clean only affected spots on the roof and should not be used to clean the entirety of the roof. Always check the recommended directions for cleaning on the products label and use accordingly.
This class of cleaners includes:
- Rubbing alcohol
- VM& P Naphtha
With this group, always keep in mind that you should wear protective clothing, use eye protection, and keep the area properly ventilated because most of these cleaners are toxic. Additionally, keep these solvents away from sparks or open flames, as they are flammable.
Applying The Paint Incorrectly
Watch a few videos in order to educate yourself on how exactly paint should be applied to metal roofs. Often, people apply paint unevenly which can cause the paint to peel sooner. As a result, they will have to do retouches sooner, which can end up being costly and time-consuming.
In order to avoid having to retouch your roof sooner, try and apply the paint as evenly as possible. You will also need to apply a good few coats of paint in order for it to last for a longer time.

Preparation is paramount, so go to great lengths to prep the metal roof properly before we even grab a spray gun and paint roller.

Finally we scour the roof to leave a slightly abraded, textured finish, as this helps your new paint bond with the metal roof.
Once its prepped, we add a primer.
But hang on, Greg, I hear you sayshouldnt you use a sealer first?
Nope. Sealers arent necessary when you paint metal roofs you only need them on tile roofs.
Having said that, the primers we use have a built-in anti-corrosive component, so theyll look good for a very, very long time.
We then wait for the primer to dry, especially in humid weather, as it needs time to cure properly. This is something the cowboys seldom worry about.

If youre one of the lucky ones that has a metal roof with no previous history of painting, then you can skip this section.
Metal roofs are rarely in a pristine, ready-to-go condition that is just waiting to be painted, so if your roof has paint already, youll need to estimate how much its going to cost to remove it. It can be expensive to repaint metal roofs.
The more layers of paint, the less likely its going to be worth it, financially, over replacing it altogether. You dont want to go into this project with a half-baked cleanup plan that just involves scraping and sanding as much as you can before adding a new coat of paint.
If your roof just has one previous coat of oil-based paint, then you should be able to get most of it removed through some hard work, provided you have the proper tools.
Youll need to start with large scrapers, down to sanding tools, and finally wire brushes. After that, you can move onto pressure washing and attending to any rusty spots.
If theres a lot of rusty areas, this could really compromise your new coat of paint, so err on the side of caution.
As for other types of metal paints, acrylic paints take more time to remove, but otherwise apply the same rules as the above instructions.
