In general, roofs are designed to be replaced every 30 years, but the lifespan of a roof depends on the material. Tile, slate, and copper roofs can last over 50 years while wood shake roofs last about 30 years.
The longevity of your roof also depends on how you maintain and care for it. So, if you are thinking about a solar panel installation, it’s natural to worry about the life of your roof.
Can your roof withstand the weight of solar panels? Keep reading to learn the answer.
Weight of Solar Panels
Understanding if your roof can handle the weight of a solar panel installation involves knowing the weight of solar panels.
The exact weight of a solar panel will differ from brand to brand. No solar panel is extremely heavy, but its solidity still allows it to withstand environmental pressures.
60-cell PV solar panels are around 35 to 45 pounds, but the average weight of solar panels like this is 40 pounds. This comes out to 2.3 pounds per square foot.
72-cell panels weigh a little bit extra, but the weight spreads out over a larger surface area. This means that the weight per square foot is about the same when compared to 60-cell PV solar panels.
On average, a 72-cell solar panel is slightly over 50 pounds or 2.4 pounds per square foot. 60-cell and 72-cell solar panels are commonly used for solar panel home installation.
Roof Evaluation
Before searching up, “solar panel installers near me,” you need to know if your roof can withstand the weight of solar panels. Along with knowing how much solar panels weigh, it is essential to get a roof evaluation.
A third-party structural engineer or architect can evaluate your home along with the solar system you want to purchase. If your roof can handle the weight, the professional will provide you with a certified letter of approval.
If your current roof cannot withstand the weight, an expert can make recommendations about the changes that need to be made first. You’ll have to take roof repair and solar installation costs into consideration if this is the case.
Are Solar Panels Safe on Your Roof?
If a structural engineer signs off on your solar system, you can trust that your roof will be safe when the solar panels are installed. To avoid issues, solar panels need to be installed correctly by the experts.
Because of this, it is not recommended to try a DIY solar panel installation. The type of roof that you have will dictate how the installation process goes.
In addition to being safe for your roof, when installed the right way, solar panels should not have an adverse effect on the longevity of your roofing system. In fact, solar panels might protect your roof because they are installed a few inches above the roof.
It’s Time for a Solar Panel Installation
After learning about the weight of solar panels and receiving a roof inspection, you should have the knowledge you need to decide on a solar panel installation.
If your roof can handle a solar system, you’ll be able to reap the many benefits of going solar. Plus, there are no adverse effects on your roof. Solar panels are safe and don’t affect the longevity of your home’s structure.
