Roof Replacement with Solar Panels: Removal, Reinstallation & Costs Explained

Roof Replacement with Solar Panels: Removal, Reinstallation & Costs Explained

If your roof needs to be replaced and you already have a solar panel system, you’re likely wondering: What now?

Removing and reinstalling solar panels isn’t just about unplugging and reinstalling — it requires planning, permits, proper equipment handling, and the right contractor who understands both roofing and solar systems. At Home Pro Roofing and Solar, we specialize in seamless, solar-smart roof replacements throughout the Bay Area.

🔧 Can You Replace Your Roof If You Already Have Solar Panels?

Yes — and in fact, this is more common than many homeowners think. Roofs generally have a shorter lifespan than solar panels. A typical asphalt composition roof lasts 20–30 years, while modern solar panels can last 25–40 years. If your roof wasn’t replaced before the solar install, a replacement might be unavoidable.

❗ Why Roofs Usually Need Replacement Before Solar

Many solar companies install panels on older roofs to close a sale quickly, without evaluating whether the roof will last as long as the solar system. This can leave homeowners with a tough decision just a few years later.

🔍 What Happens When the Roof Fails After Solar is Installed?

If your roof starts to leak, sag, or show signs of aging, it’s crucial to replace it. But with solar on top, you’ll need to:

  • Safely remove the solar panels
  • Replace the roofing system (shingles, underlayment, vents, flashing, etc.)
  • Reinstall the solar panels, ensuring optimal performance

🛠️ What’s Involved in Removing and Reinstalling Solar Panels?

At Home Pro Roofing and Solar, we handle the full scope of your project—roofing, solar, battery backup, and permits—so you don’t have to coordinate multiple contractors.

🔁 Step-by-Step Process:

  1. Pre-inspection and assessment of your roof and solar system
  2. City permit pulled (if required for your location)
  3. Panels safely removed, including wiring and inverters
  4. New roof installed (composition, CertainTeed Solaris, TPO, etc.)
  5. Solar panels cleaned, tested, and reinstalled
  6. System inspection and recommissioning

✅ Why Choose a Roofing Contractor That Also Handles Solar?

Many roofers outsource the solar removal to third-party electricians or solar techs. That leads to delays, finger-pointing, and potential code violations.

Home Pro Roofing and Solar is a licensed contractor for both roofing and solar, serving Santa Clara, San Mateo, and Alameda Counties. We handle everything in-house or with preferred partners.

🧰 How to Choose the Right Contractor for Roofing with Solar

Replacing a roof with solar on it isn’t a standard job. Here’s what to look for:

✔️ Look for a Local Company with Roofing + Solar Expertise

  • They should be licensed in both trades
  • They should have experience coordinating permits and PG&E/PTO

✔️ Ask About Panel Handling, Storage, and Insurance

  • Make sure the company is insured to handle solar equipment
  • Ask how panels are stored during roof work

✔️ Importance of Coordinated Scheduling

Avoid delays by using one contractor for both services. At Home Pro, our roofing and solar crews are scheduled together — no waiting weeks to reinstall panels after roofing is done.
