What is the Average Cost of Roof Painting? Are There Tips to Reduce Costs?

Hello! This is Kakeru Koumuten Co., Ltd.!

Roof painting can be quite costly.

Many of you reading this article might be thinking,

“I wonder how much it will cost…”

“I want to request it as cheaply as possible…”

There are likely many people with these thoughts.

Therefore, this time,

we will explain in detail the average cost of roof painting and tips to keep costs down.

What is the average cost of roof painting?

The cost of roof painting is often around 300,000 to 600,000 yen.

However, the total cost can vary significantly depending on various factors such as the condition of the roof, the type of paint used, and the contractor you choose, so it is advisable to consider the above as a rough estimate.

What factors determine the cost of roof painting?

Next, let’s explain in detail the factors that determine the cost of roof painting.

Roof Area

The cost of roof painting varies greatly depending on the area of the roof.

The larger the roof area, the more time it takes to paint and the more paint is required, resulting in a higher total cost.

Roof Slope

If the roof slope is steep, the painting cost will also be high.

This is because a steeper slope increases the surface area that needs to be painted.

Additionally, if the slope is steep, scaffolding may be less stable, which can lead to higher scaffolding costs than usual, so caution is needed.

Type of Roofing Material

There are various types of roofing materials, and the painting process differs for each.

Expensive roofing materials often lead to higher painting costs, so careful consideration is necessary.

Type of Paint

In roof painting,

・Acrylic paint
・Urethane paint
・Silicone paint
・Radical control type paint
・Fluorine paint
・Photocatalytic paint
・Inorganic paint

These are commonly used options.

However, each type of paint has its own characteristics, advantages, and disadvantages, and the more high-performance the paint you choose, the higher the total cost will be. Therefore, we recommend considering your budget while making your decision.

Condition of the Roof

The cost of roof painting can vary significantly depending on the condition of the roof.

If there is no major damage to the roof, painting can be done at a minimal cost.

However,

・If rust is progressing
・If there are many cracks

In such cases, repair work will be necessary for those areas, which will increase the total cost.

Tips for Reducing Roof Painting Costs

Next, let’s take a closer look at tips for reducing the costs of roof painting.

Choose Long-lasting Paint

To reduce the costs of roof painting, it is important to choose paint with a long lifespan.

Long-lasting paint tends to have a higher unit price, so it may seem expensive in the short term, but it allows for a longer span until re-painting is needed, often making it more economical overall.

The most commonly used paint for roof painting is silicone paint.

Silicone paint has a lifespan of 8 to 12 years, which is relatively long, and its unit price is not excessively high, making it ideal for those who prioritize cost performance.

Some may think,

“Let’s lower the grade of the paint to reduce the unit price”

However, if you decide on paint based solely on the unit price, there is a high possibility that you will need re-painting soon or that it won’t lead to improved comfort, so be cautious.

Obtain Multiple Estimates

To reduce the costs of roof painting, it is essential to obtain estimates from multiple contractors.

This is because the costs can vary significantly depending on the contractor, even for the same work.

By obtaining estimates from several contractors, you can simultaneously check:

・The market price for roof painting
・Unique services offered by each contractor
・Quality of service

This way, you can efficiently find reputable contractors.

When obtaining multiple estimates, it is important to request estimates with the same content.

If the content changes, it will become difficult to compare prices, so please be careful.

Requesting Simultaneously with Exterior Painting

To reduce the cost of roof painting, it is key to request it simultaneously with exterior painting.

This is because if you request roof painting and exterior painting separately, you will need to carry out scaffolding work twice, resulting in higher total costs.

By carrying out both at the same time, you can complete the scaffolding work in one go, making it easier to keep costs down.

When painting both the exterior and the roof at the same time, it may feel like the costs are high in the short term, but in the long run, it becomes quite economical. Therefore, if the deterioration of the exterior is becoming noticeable, we recommend considering simultaneous requests.

Requesting During Off-Peak Season

Roof painting has busy and off-peak seasons.

During the busy season, there is a flood of requests, so prices tend to rise due to the relationship between supply and demand.

Conversely, during the off-peak season, the number of requests decreases, making it more likely that you can request services at a lower price compared to the busy season.

The off-peak season for roof painting is from January to March and around May to July, so

if you are thinking, “I want to do roof painting as cheaply as possible,”

please consider requesting during this timing.

Check for Available Subsidies and Grants

There may be subsidies and grants available for roof painting.

If you can effectively utilize these, the amount you have to bear will decrease, making it easier to keep total costs down.

However, subsidies and grants are often managed by local governments, so they may not be available in all areas.

Additionally, the eligibility conditions also vary by municipality, so it is recommended to check in advance.

Requesting from Contractors that Perform In-House Work

To reduce the cost of roof painting, it is important to request from contractors that perform in-house work.

Some contractors may subcontract the work to affiliated subcontractors and take a margin, which can increase total costs.

While such contractors are not necessarily malicious, the presence of a middle margin will increase the overall cost.

By requesting from a contractor that performs completely in-house work, you can cut unnecessary costs, making it more likely that you can request services at a lower price.

Points to Note When Trying to Reduce Roof Painting Costs

Finally, let’s take a closer look at the points to note when trying to reduce roof painting costs.

Beware of Extremely Cheap Contractors

Among those who want to reduce roof painting costs,

“The cheaper, the better”

is a thought that some may have, but this mindset is very dangerous.

Some contractors may offer prices that are far below the market rate, but if you request from such contractors,

・Shoddy work
・High charges

there is a high possibility of getting involved in troubles, so please be cautious.

Focusing on Immediate Costs May Lead to Regret

Roof painting can be done at a significantly lower cost compared to roof overlay (cover method) or complete roof replacement.

Some may choose roof painting simply because it is

“cheap,”

but if you get caught up in immediate costs, there is a high possibility of regret later on.

This is because while roof painting is relatively inexpensive, its lifespan is comparatively short, requiring repainting soon.

In contrast, roof overlay (cover method) and roof replacement have longer lifespans, allowing for extended intervals between maintenance, which can be more cost-effective in the long run.

Additionally, by implementing roof overlay (cover method) or roof replacement, you can expect improvements in functionality, so let’s decide on the type of maintenance to perform based on a comprehensive assessment of various factors.

Summary

Roof painting costs around 300,000 to 600,000 yen.

However, the cost of roof painting can vary due to various factors, so it cannot be definitively stated.

In some cases, costs may exceed the market average, so caution is necessary.

By practicing the methods introduced this time, it will be easier to keep the costs of roof painting down, but if you decide solely based on cost, the likelihood of regret increases, so

・roof overlay (cover method)
・roof replacement

let’s carefully consider options other than painting as well.

“I don’t know which construction method is best”

“I want to hire a reliable contractor”
