How to Tell if Your Roof Is Good for Solar

Thinking about going solar in 2025? It’s one of the smartest investments you can make, cutting your energy bills, locking in tax incentives, and potentially boosting your home’s value.

But is your house a good fit for solar panels?

The answer for most California homes is yes. And with the right installer, it’s often easier than you’d think. Here’s how to find out if your roof is ready for solar.

What to Consider When Assessing Your Roof for Solar 

There are a few key factors to consider when deciding whether solar makes sense for your home. But keep in mind, we can make solar panels work for most roof types! 

Even if you don’t think your house is a perfect fit, we encourage you to reach out. Our team will help you offset as much of your electricity costs as possible by placing high-efficiency solar panels in the best available location on your roof. 

Roof Orientation 

The direction your roof faces determines how much sunlight it gets throughout the day. In the US, south-facing roofs get the most sun and are therefore best for solar. But west and east-facing roofs can also work well. 

Shading 

Solar panels need light to generate electricity. If your roof is heavily shaded, it will impact the amount of power you can generate. 

When you go solar with Premo, we’ll run a detailed shade analysis to pinpoint the most productive areas on your roof. 

Roof Size & Space 

You don’t need a giant roof to go solar. What matters is how much open, unshaded space you have to install panels. Most panels are about 3.5 feet by 5.5 feet, and a typical home might need anywhere from 15 to 25 panels, depending on your energy use.

Obstructions like skylights or roof vents can reduce the available space, but that doesn’t mean your home can’t qualify. High-efficiency panels produce more power in a smaller footprint, and they’re a great option for homes with limited roof space.

Roof Age & Condition 

Solar panels are designed to last 25 years or more, so your roof should be in good condition before you install them.  

At Premo Solar, we have decades of roofing experience. Our roofing team, Premo Roofing, can easily assess your roof and handle any necessary roofing work before you go solar. You don’t have to worry about juggling multiple contractors—we’ll take care of everything. 

Other Factors to Consider 

When deciding whether solar is worth it for your California home, your roof is a big part of the equation. But it’s certainly not the only factor. Others include: 

Your Electricity Costs

The more money you spend on electricity, the more you stand to gain by going solar. In California, we pay some of the highest electricity costs in the country, and rates are still going up. Those high costs make solar worth it for most homes. You’ll save on your bills, and you’ll be protected when the next rate hike comes, which it inevitably will. 

How Long You Plan to Stay in Your Home

The longer you stay in your home, the stronger the return you’ll see through electric bill savings. But solar can still be worth it if you’re planning to move in a few years. In many cases, solar panels increase resale value and can even help your home sell faster. 

Keep in Mind: The Perfect Roof Doesn’t Exist 

It’s important to evaluate your roof’s solar potential, but don’t get too hung up on it. If you want to install solar panels, chances are, we can make it work. Our team works around challenges with creative solutions that make solar viable for almost any home. 

Even if you can’t cover 100% of your electricity costs with solar, it’s likely still worth it given California’s high electricity rates. Your panels will bring your costs down as much as possible, and you’ll be able to buy what you need from the electric grid to make up the difference.
