If you’re considering going solar, you’re asking the right questions—and you should be. This isn’t just another home upgrade. This is an investment. One that could impact your energy bills, the value of your home, and your peace of mind for years to come.
Here at Guardian Roofs, we know that most homeowners in San Marcos aren’t just looking for a trendy fix. You’re looking for innovative, reliable solutions that hold up over time. And when it comes to solar roofing, we hear many of the same questions—good, honest questions. That’s why we’ve pulled together this solar roofing FAQ: a guide to help you sort through the details, weigh your options, and move forward with clarity.
Whether you’re considering solar panels for the first time or ready to take the next step, these answers are designed to help you feel confident and prepared.
Let’s dive into the most common questions about solar roofs, starting with the one that’s likely at the top of your list.
What Is a Solar Roof and How Does It Work?
A solar roof is exactly what it sounds like—it’s a roofing system that includes solar technology, allowing your home to generate electricity from sunlight. There are two main types of solar roofs:
- Traditional solar panels installed over your existing roof.
- Integrated solar shingles or tiles that are built into the roof structure.
Most homeowners go with the first option—traditional panels—because it offers the best balance of cost, efficiency, and availability. At Guardian Roofs, we’ll help you assess your current roof and determine which type of solar solution makes the most sense for your home.
How Long Do Solar Roofs Last?
This is one of the most common questions we get. And the answer? Longer than most people think.
High-quality solar panels are built to last 25 to 30 years—and often longer. Even after that, they usually continue producing electricity, just at a reduced rate. Most manufacturers guarantee that their panels will still perform at around 80–85% capacity after 25 years.
But here’s the important part: your solar panels are only as reliable as the roof they’re installed on. If your roof isn’t up to par, you could be facing costly panel removal down the road just to fix or replace the roof underneath.
That’s why we always start with a thorough roof inspection before any solar installation. Guardian Roofs ensures your roof is strong, stable, and ready to support solar for decades to come.
Is My Roof Suitable for Solar Panels?
Maybe. It depends on a few important factors:
- How much sunlight does your roof receive?
- Are there trees, chimneys, or nearby buildings that create shade?
- What’s the current condition and age of your roof?
We help San Marcos homeowners evaluate all of this. We don’t just give you a yes or no—we give you the why behind it. With a solid roof and enough sunlight, most homes are great candidates for solar.
What Types of Roofs Work Best with Solar?
Another common concern in the solar roofing FAQ is roof material. Some are easier to work with than others:
- Asphalt shingles: Easy to install solar panels on and widely used.
- Tile roofs: Popular in California but require special handling during installation.
- Flat roofs: Work just fine with the right mounting system.
- Metal roofs: Very durable and ideal for solar panels.
Guardian Roofs has experience working with all of these roofing materials. We’ll guide you on the best steps based on your current roof and your long-term solar goals.
What Kind of Maintenance Is Required?
One of the benefits of solar roofing is its low-maintenance nature. But that doesn’t mean you can ignore it entirely.
Here’s what smart maintenance looks like:
- Keep your panels clean, especially after wind or dust storms.
- Trim nearby trees to prevent shade or falling branches.
- Monitor your system’s energy output so you can spot any dips in performance.
- Have your roof inspected every couple of years to make sure it’s still in good shape beneath the panels.
At Guardian Roofs, we offer inspection and maintenance services to help you protect both your solar system and the roof it depends on.
What If My Roof Needs Repairs After I Go Solar?
This is a major concern—and one of the most important items in any solar roofing FAQ.
If your roof needs repairs after your solar system is installed, the panels have to be removed and reinstalled. That means additional costs and time.
Here’s our advice: don’t put a 30-year solar system on a 10-year roof. If your roof is aging or already showing wear, get it inspected and, if needed, replaced before the solar panels go up.
Guardian Roofs performs solar-readiness assessments, so you know exactly what condition your roof is in and what steps to take before you commit to solar.
Will Solar Add Value to My Home?
In many cases, yes. Homes with solar systems tend to sell faster and for more money—especially when energy prices are high. But only if the installation is done right.
A professionally installed solar system on a well-maintained roof adds long-term value. A system thrown onto a damaged or aging roof? That’s a red flag for future buyers.
That’s why at Guardian Roofs, we handle roofing and solar-readiness as one package. We help you protect your investment and increase your home’s appeal—inside and out.
Should I Replace My Roof Before Installing Solar?
If your roof is more than 10–15 years old, the answer is likely yes.
Think long-term. If your panels last 25 to 30 years, your roof needs to be able to last just as long—or you’ll face the hassle and expense of removing the panels to fix the roof underneath.
Guardian Roofs can inspect your current roofing system and help you make a smart, informed decision. And if you do need a replacement, we’ll handle it efficiently so you’re solar-ready as soon as possible.
