How Much Does It Cost to Paint a Metal Roof in 2024?

Applying a coat of paint is the primary function of protecting the roof from corrosion, moss, and algae. Painting a metal roof extends its service life while improving aesthetics and reducing the need for repairs. If your roofing looks tarnished or you want to change its color, painting can be a great home improvement project.

However, like any other home update, painting the roof requires careful budgeting based on accurate labor and material costs. Features like roof size, construction, and slope, as well as the selected paint manufacturer and type, most affect the total price. As of today, the national average cost to paint a metal roof is $2,400, but depending on the roof's features and local labor rates, it might be as low as $455 or as high as $6.550.

Read on to discover all the factors that affect the average price of metal roof paint. We will then discuss the types of metal roof paints and additional criteria that affect the overall material and labor cost.

The Cost to Paint a Metal Roof per Square Foot

Often, contractors quote prices in square feet, knowing each roof has its custom dimensions. Do not be afraid to be cheated. You can always check how their prices correspond to the average cost of painting a metal roof.

The Cost to Paint a Metal Roof by Paint Type

Painting costs may also differ by coating. The two most common roof painting types are Silicone Modified Polyester (SMP) and Polyvinylidene Fluoride (PVDF). Both coatings protect the metal roof from weathering for a long time, except PVDF's fading speed is slightly better. Let's dive into the details to help you make an informed buying decision. 

Polyvinylidene Fluoride (PVDF) Paint

PVDF is one of the best organic coatings available, providing excellent color retention and corrosion resistance. It comprises 70% fluorocarbon resin and 30% acrylic resin with special weather-resistant pigments. With fluorine resin as the primary film-forming material, PVDF is ideal for protecting metal building panels such as steel and aluminum. Under normal conditions, its service life can reach 25 years.

Compared with traditional paints, PVDF coatings are excellently resistant to corrosion, UV, dirt, and scratches. As a result, they will retain their color and luster after 20 years of outdoor use. In addition, they are available in a wide range of colors.

Silicone-Modified Polyester (SMP) Paint

SMP coating is also a chart-topping paint in the market. It combines the characteristics of polyester resin and silicone resin, featuring excellent durability, color retention, and exceptional corrosion and weather resistance. In the general environment, its service life is more than 10 years. In contrast to PVDF, this coating is cheaper and less prone to chalking, so it is often used in areas with strong wind.

Here are the metal roof painting costs by paint type.

Regardless of the brand of paint you use, you will need around 1 gallon of paint for 100 square feet of roof.

Factors Affecting the Total Metal Roof Painting Cost

Not only the type of paint determines the final price. The project's complexity and preparation of the area to be painted also fall into the primary cost-formation factors. Pay attention to the following criteria to ensure your ballpark metal roof painting cost is accurate.

Power Washing

Cleaning is an essential stage in the preparation of the roof for painting. Leaves, dirt, salt, and sand are washed out using high-pressure equipment. You might also need to clean the site of corrosion and old paintwork with special brushes for metal and grinders. The renting of the whole equipment set will cost you about $55 - $125 per day.

But if you don't have time to do it yourself, you can hire a skilled roofing contractor. Pressure washing usually costs $65 to $120 per hour. For example, cleaning a 1,200-square-foot house takes roughly 6 hours and costs about $360 - $600.

Sealing

As a rule, along with painting, roof contractors expect you to seal your roof. The cost of roof sealing is $7 - $35 per square. Sealing will provide your roof with an increased level of protection, including:

• water resistance
• fire resistance
• temperature retention
• mold protection

Roof Size

Most roofers calculate the cost of materials per square foot, although sometimes they charge by the hour. To determine the cost of painting the roof, you should first calculate its size. To do that, multiply your actual home's square footage by 1.5. Next, find out the rate of a local roof painting contractor for a square foot and multiply it by the received number. For example, a 3,000-foot roof for $2,50 per square foot will cost you $6.000 if fully painted.

Roof Pitch

Its slope and design complexity determine how much to paint a metal roof. The price change starts from a pitch of 3 inches or more. A steeper pitch roof will cost more to paint since it needs more workforce, safety measures, and equipment. The overall cost might rise to 20%, depending on the roof's slope.

Quality of Paint

The composition of the paint should be selected based on the material of the existing roof. For instance, acrylic latex paint suits bare metal roofs and can be applied over old paint. On the other hand, oil paints are best for thorny metal roofs, while acrylic works well on galvanized ones.

Go to the local home improvement store to explore the assortment of paints. You can also consult a professional contractor to discover how the cost of painting a metal roof may change depending on the selected paint type and brand. Don't compromise the quality of the paint to save a few dollars, as using watery paint on a metal roof can lead to poor adhesion, peeling, and reduced durability. 

Color of Paint

Painting a metal roof will also require picking a suitable color. The color choice should be guided by aesthetic wishes, the exterior of the house, and the surroundings. However, you can also follow more practical targets. For example, if you want to enhance your roof's energy efficiency, go for lighter colors that reflect heat.

If the desired color is out of the list of standard manufacturer colors, go for a custom option. Specially designed paint adapted to your siding shade will cost you 1.5 - 2 times as much but can greatly enhance your home's curb appeal. 

Local Labor Rates

Some companies charge an hourly rate ($30-$55 per hour) for roof painting, but the estimated price often depends on the materials and complexity. For example, the roof's slope or location can raise the painting a metal roof cost. Contractor rates also vary from state to state: the larger and more populous the area, the higher the cost.

Season

The time intervals from April to May and from September to early October are ideal for applying paint on the roof, as there is no scorching sun or high precipitation outside. These months are seasonal peaks for roofing jobs, including painting, resulting in rates spiking by 5-7%. That is why it makes sense to book a contractor in advance to avoid paying through the nose. 

Labor Cost to Repaint a Metal Roof

If your roof is covered with an old coat of paint, you may need to renew the home's former aesthetics. You can start with other restoration work, like a roof check and cleaning, but sooner or later, you will have only one wish — to repaint it.

If you’re wondering how much it costs to repaint a metal roof, the answer will be around $1,450 - $3,325.

As with other roofing jobs, you can choose to hire a professional or paint the metal roof yourself. Depending on your choice, you can calculate the cost of painting the metal roof according to the following table.
