Do I Need a New Roof Before Going Solar?

If you're thinking about going solar in one of the first questions you might have is: What about my roof?

At SLM Solar, we’ve installed hundreds of solar systems across Ocean County and beyond, and this question comes up all the time. The truth is, not every roof is ready for solar — but that doesn’t mean you can’t move forward. Here’s what you need to know.

How Long Does a Roof Typically Last?

Most asphalt shingle roofs last around 20 to 30 years. Tile and metal roofs can last longer. If your roof is newer — say, under 10 years old — you're probably in the clear. But if your roof is older, or showing signs of wear, it may be worth addressing before installing panels.

Why Roofing Matters for Solar

Solar panels are designed to last 25 years or more. You don’t want to install a system now and then have to remove it in a few years just to replace the roof underneath. That’s not only inconvenient — it can cost you extra in labor and reinstallation.

This is why a good solar company will always assess your roof condition before moving forward. To ensure all parties are protected, SLM Solar conducts in depth inspections of all homes prior to installation. For your convenience, the inspection may even be done the same day as the consultation.

What If My Roof Needs Work?

At SLM Solar, we’ll inspect your roof before we design your system. If it’s in good shape, we move ahead. If it needs attention, we’ll give you honest guidance.

In many cases, we can bundle a roof replacement and solar installation into one seamless project. That means:

• One team coordinating both jobs

• One financing package (with up to 25 year terms)

• One-day installation (when possible)

It also means peace of mind that your roof will last as long as your solar system does.

Can I Still Get Incentives If I Replace My Roof?

Yes. The 30 percent federal tax credit applies to solar-related expenses — and if the roof work is required to support the system (such as structural reinforcements or specific materials under the panels), a portion of the roofing costs may also qualify.

We’ll walk you through what qualifies and help you with the paperwork.

Bottom Line: You Don’t Need a Perfect Roof — But You Do Need the Right Plan

Going solar is a long-term investment, and your roof is the foundation for it. Whether your roof is new, aging, or needs to be replaced, we’ll help you figure out the best path forward.
