Installing solar panels can be one of the smartest long-term investments you make for your home. But if your roof is aging, it’s important to think carefully before you make this investment. Solar panels typically last 25 years and sometimes more, and the condition of your roof can impact the installation of your panels, while your panels can make it difficult to replace your roof when it’s needed. So, what do you need to know about getting solar panels up on an old roof? Keep reading to find out.
Assessing the Condition of Your Roof
Before you commit to going solar, you should evaluate the current state of your roof. If it’s more than 15 to 20 years old, or it’s showing signs of damage like curling shingles, leaks, or sagging, you should talk to someone about repairing or replacing it before you try to install any solar panels. A reputable solar installer will inspect your roof before installation begins to ensure that its structure can safely support the weight of the panels. If your roof is old or in bad shape, they may tell you that an installation isn’t even possible.
Replacing Your Roof Before Installation
If your roof is nearing the end of its lifespan, replacing it before you add solar panels is the smarter financial choice. While putting on a new roof may delay your ability to get solar, it prevents twice the labor costs later, as you would need to remove the panels to install the new roof, then reinstall them after roofing is complete. By replacing it now, the panels and roofing can age together. You may even be able to work with your roofing contractor to have solar installation included in the roofing process.
The lifespan of your roof will vary depending on the material it’s made of. Asphalt shingles, the most common roofing material, typically last between 15 and 30 years, with basic 3-tab shingles falling on the lower end of that range. So, if your roof is more than 15 years old, you’ll want to replace it. Metal roofs and roofs with clay or concrete tiles can last more than 40 years, so you’ll have more wiggle room with a solar installation on these homes.
Reinforcing and Preparing Your Roof
If you decide to keep your existing roof, make sure it’s structurally sound enough for panels. Talk to your installer about reinforcing any weak areas, replacing damaged shingles, and ensuring the flashing and other materials under the shingles are in good condition. This will give your roof a higher chance of lasting throughout the lifespan of your solar panels.
So, before you put a single Phono Solar panel on your roof, always make sure to check your roof’s condition and ensure it’s able to bear the wait of solar panels.
