Can I Go Solar With a New Roof? What PA Homeowners Need to Know

One of the most common questions we hear from Pennsylvania homeowners is: "I just got a new roof — can I still go solar?" Or the reverse: "I need a new roof — should I do solar at the same time?"

The short answer to both questions is yes. Here is everything you need to know.

If you recently had your roof replaced, congratulations — you are actually in an ideal position to go solar. Here is why:

Solar panels are designed to last 25–30 years. Ideally, your roof should have at least 15–20 years of life remaining when you install solar, so you do not have to remove and reinstall the panels for a roof replacement mid-system-life.

A brand-new roof means your solar system and your roof will age together, and you likely will not need to touch either for decades.

When we install solar panels, we assess your roof's structural integrity, pitch, orientation, and condition. A new roof eliminates any concerns about leaks, weak spots, or premature aging under the panels.

If your roof is brand new, we recommend waiting at least 30 days after installation before adding solar panels. This gives the roofing materials time to fully settle and cure. After that, you are ready to go.

If your roof needs replacement and you are considering solar, doing both projects simultaneously is often the smartest financial move. Here is why:

Roofing and solar installation involve overlapping labor — both crews work on your roof. When you coordinate both projects, you eliminate redundant labor costs and reduce the total time your home is under construction.

In many Pennsylvania municipalities, you can pull a single combined permit for roofing and solar, streamlining the approval process.

The 30% federal Investment Tax Credit applies to the cost of your solar system. If you are replacing your roof specifically to support solar installation, a portion of the roofing cost may also be eligible for the tax credit. Our team will help you document this properly.

Some of our financing programs allow you to bundle roof replacement costs with your solar installation into a single monthly payment — making the combined project more affordable than doing each separately.

If your roof is 10–15 years old but in good condition, you may be able to go solar now without replacing it first. Our installation team will assess:

• Remaining roof life — Is there enough life left to justify solar installation?
• Structural integrity — Can the roof support the weight of solar panels?
• Condition of shingles — Are there any areas that need repair before installation?

In many cases, we can install solar on a roof with 10+ years of remaining life and plan for a future roof replacement that includes panel removal and reinstallation (typically $1,500–$3,000 depending on system size).

Solar panels can be installed on most residential roof types common in Pennsylvania:

• Asphalt shingles — The most common and easiest for solar installation
• Metal roofing — Excellent for solar; standing seam metal is ideal
• Flat roofs — Can work with ballasted racking systems
• Tile roofing — Possible but requires specialized mounting hardware

The main factors that affect solar suitability are roof orientation (south-facing is best), pitch (15–40 degrees is ideal), and shading from trees or nearby structures.

Whether you just got a new roof or need one, solar is absolutely within reach. The Grid Guardian Team will assess your specific situation and give you an honest recommendation — including whether to wait, replace first, or bundle both projects.
