Replacing A Roof With Solar Panels: Step-by-Step Guide

Is your roof due for replacement, but you already have solar panels installed? Replacing a roof with solar panels might seem daunting at first, but it’s totally manageable with the right approach. A solar roof replacement does require a few additional steps compared to a standard roof replacement, but with proper planning, it doesn’t have to be a headache.

The key is making sure your solar investment is protected throughout the process. Whether you're dealing with a worn-out roof or upgrading to a more durable roofing material, it’s important to know what to expect when you have both a new roof and solar panels to consider. This guide will walk you through the essential steps to ensure your solar system continues to operate efficiently while you get a brand-new roof installed.

Solar panel removal and reset—also known as solar panel removal for roof replacement—is a critical part of the process. Make sure to work with a contractor who can handle both the roofing and solar panel reinstallation to keep everything in top condition.

Step 1: Assess If a Solar Roof Replacement Is Necessary

Before moving forward with a roof replacement with solar panels, evaluate the condition of your roof. Signs you may need a replacement include:

• Roof age over 20 years

• Missing, curling, or cracked shingles

• Active leaks or visible water damage

• Sagging or structural deterioration

Addressing these issues early can prevent costly damage to your solar system. A proactive solar roof replacement reduces the risk of needing to remove and reinstall your panels more than once.

In some cases, solar panels help shield your roof from sun and weather, potentially extending its lifespan. But if underlying materials are failing, removing solar panels for roof replacement is necessary to protect both the roof and your energy investment.

Step 2: Hire Professionals for Solar Panel Removal and Reinstallation

When it’s time for a solar roof replacement, one of the key steps is removing and reinstalling your solar panels. Many solar companies offer this service as part of the roof replacement with solar panels process. If your original solar installation company has closed down, it’s essential to find a qualified contractor with experience in solar panel removal and reinstallation.

Step 3: Protect and Store Your Solar Equipment

Once your solar panels are removed, it’s important to protect your system components during the roof replacement with solar panels. Your solar contractor should:

• Document system performance before disconnecting anything

• Label cables, inverters, and hardware to avoid confusion later

• Store panels in a clean, dry, shaded area to prevent weather damage

Proper storage ensures your equipment is ready for a smooth solar panel reinstallation after the roof work is done.

Step 4: Complete the Roof Installation

With the solar panels safely removed, your roofing contractor can proceed with the roof replacement. Choose materials compatible with solar—such as asphalt shingles or metal roofing—for long-term durability.

• Ensure all flashing, underlayment, and roof deck repairs are completed before reinstalling panels

• Discuss potential upgrades, like attic ventilation, that may improve system performance

• Make sure the new roof is sealed and structurally sound to support panel mounts

A high-quality roofing job lays the foundation for long-term solar success.

Step 5: Reinstall and Recommission Your Solar System

After the roof work is complete, your contractor will perform a full solar panel reinstallation. This typically includes:

• Reinstalling racking and securing it to the new roof

• Reconnecting wiring, inverters, and monitoring equipment

• Testing voltage and production to verify functionality

• Reviewing performance against pre-removal benchmarks

This is also a good time to consider upgrades, like adding battery storage or replacing outdated panels.
