However, when painting the roof or during roof renovations, careful consideration must be given to handling them.

This article will provide a detailed explanation of whether solar panels should be removed during roof painting or renovations, and how much the removal and reinstallation costs will be.

What problems can arise when there are solar panels during roof painting?

Even with solar panels installed, roof painting can still be carried out.

However, since painting will avoid the areas with solar panels, if the panels need to be removed, it is expected that the roof will look quite unnatural.

For this reason, it is generally recommended to temporarily remove the solar panels before proceeding with the renovations.

What are the roof renovation methods for houses with solar panels?

Next, we will explain in detail the roof renovation methods for houses with solar panels.

Before installing solar panels

If solar panels have not yet been installed, you can proceed with painting as usual.

If you are unsure whether to install the solar panels first or renovate the roof first, please prioritize the roof renovation.

Remove the solar panel section for renovation

Even if solar panels are already installed,

“I absolutely do not want to remove the solar panels.”

If that’s the case, the solar panel can be removed to allow for painting.

Regarding the area beneath the solar panels, it is often relatively undamaged due to being shielded from rain and UV rays.

However, as mentioned at the beginning, if you plan to remove the solar panels soon or if you are concerned about the difference in roof paint color after removing the solar panels, it would be better to detach and renovate.

Detach and Renovate the Roof with Solar Panels

If a significant amount of time has passed since the last roof renovation, it may become necessary to detach the solar panels for renovation.

Both the roof overlay method and re-roofing will require the removal of the solar panels.

By detaching the solar panels, you can achieve a cleaner finish on the roof.

However, in this case, in addition to the roof painting costs, detachment fees may also apply, so be sure to check in advance.

How much does it cost to detach solar panels?

The cost for detaching solar panels is generally around 5,000 to 30,000 yen per panel, depending on the number of panels.

In addition to this cost,

・Labor costs
・Various expenses for panel storage
・Costs for specialized materials and racks for the overlay method or re-roofing
may also be incurred.

The longer the construction takes, the more labor costs and panel storage fees can accumulate, so this should also be checked in advance.

What are the precautions when detaching solar panels?

Finally, let’s take a closer look at the precautions when detaching solar panels.

Manufacturer’s warranty may expire

For several years after purchasing solar panels, the manufacturer’s warranty is usually in effect.

However, detaching them may void this warranty.

The reason is that detaching can potentially damage the panels or wiring.

The warranty period for solar panels is typically set between 10 to 20 years, and if you are past the warranty period, there is no particular concern, so rest assured.

Additional costs may arise depending on the condition

Solar panels are often secured to roofs made of colonial or shingle materials by drilling holes and using brackets.

When detaching, these brackets must be removed and then reattached.

However, in some cases, the brackets that were removed may not be reusable.

At this time, there may be additional costs incurred due to the need to change to new fittings.

Inexperienced contractors may cause damage

Solar panels are very delicate machines, so if you hire a contractor with little experience, there is a possibility of causing damage.

When requesting the installation or removal of solar panels, it is important to thoroughly check whether the contractor has a proven track record.

Roof replacement or overlay work is recommended over painting

Many people may be considering removing and reinstalling solar panels to paint the entire roof.

Of course, roof painting is one option, but depending on the age and condition of the roof, it may be more cost-effective to consider:

・Roof replacement work
・Overlay work

This is because roof replacement and overlay work tend to have higher durability compared to painting.

The primary purpose of painting a colonial roof is to enhance its appearance, so it does not improve durability or lifespan. If you are considering long-term cost performance, you should think about roof replacement or overlay work.

Here are examples of solar panel installation and removal associated with roof overlay work!

This is a construction photo taken when we applied the overlay method using IG Industrial/Super Galtect to a colonial roof with solar panels!

1. Before construction (colonial)

We will temporarily dismantle the solar panels and the base rack. Since we will be changing to a rack specifically for Galtect, all existing base racks and fittings will be disposed of.

2. Completion of overlay work

This is after the completion of the Galtect overlay work. For more details on the Galtect overlay work, please refer to this link!

3. Installation of new base rack fittings

The existing base was fixed by making holes in the roof, but the new hardware grips the Galttect main body to secure the solar panels. This reduces the risk of leaks and the burden on the roof.
There are applicable brackets for each manufacturer and model of solar panel. Older solar panels may not have compatible brackets available.

4. Installation of solar panels

The removed solar panels are put back in place to complete the process!

Summary

Many people may be concerned about the handling of solar panels during roof painting or roof renovations.

When removing solar panels, costs such as removal and installation fees, labor costs, and storage fees will be incurred.

If you are looking to keep costs down or prioritize long-term cost performance, it is likely that overlay work or re-roofing work will be more economical than painting work, so please consider it.
