Should you replace your roof before adding solar panels?
If your roof has been in use for a long time or is slightly damaged, it is recommended that you replace the roof at this time. If you do not replace the roof in time at this point, and only replace the roof at a later stage during the use of the solar panels when the roof is not able to support the solar panels, it will not only increase the cost of removing the roof, but will also require the removal of the solar panels, which may invalidate the warranty on the solar panels and cause even more damage.
If your roof can support the weight of the solar system and both have a fairly long lifespan, there is no need to replace the roof.
However, some installers may not recommend replacing your roof just for the payoff of installing the solar panels, and when the solar panels need to be removed in order to replace the roof, you are the one who is really worried.
Below we will give you an overview of when our roof needs to be replaced.
How do I know if I need to replace my roof?
Before installing solar panels, you need to inspect your roof and determine its remaining lifespan. Normally, asphalt roofs have a life expectancy of 20-30 years, concrete roofs have a life expectancy of 50 years or more, and metal roofs have a life expectancy of between 20-50 years. If there is a difference between your roof’s useful life and the life of your solar panels, you will need to replace your roof as soon as possible to avoid major damage.
If the service life of your roof is similar to that of solar panels, but your roof is damaged, you can avoid installing solar panels on damaged roofs or repair or replace your roof in time.
If you have to replace your roof, is it still worth it to go solar?
Most people may think that replacing the roof is unnecessary and may increase the cost of your budget. Installation of solar panels is done directly on the old roof, but when you need to replace the roof at a later stage, you realize that the cost is higher at that point. However, as explained by our experts, the electricity savings from solar power far offsets the cost of roof replacement, and the solar panels cover the roof, which reduces the amount of sunlight hitting the roof to prolong the life of the roof.
FAQ
Depending on the type of roof you have, the roof will need to be replaced once before the solar panels are installed and may be replaced again at a later date. Like an asphalt roof, there is a high probability that the roof will be replaced a second time in the later stages of the solar panel’s life. However, like a concrete or metal roof, there is basically no chance of replacing the roof again without much damage while the solar panels are in use.
There may be some damage to the roof, and solar panels will increase the weight load on the roof. However, solar panels will also protect the roof and extend its life. Because solar panels protect the roof from direct sun or rain, and because of their stabilizing structure, they reduce the effects of wind on the roof, making it more stable and durable.
