Coordinating Solar Panels with Roof Replacement in Massachusetts
If you have solar panels and your roof is approaching end of life, you have a coordination problem.
The roof will outlast the solar panels' warranty in many cases. But sometimes the timing does not work out.
Here is how to handle it.
Option 1: Replace Roof BEFORE Installing Solar
The ideal scenario. If your roof is over 15 years old and you are considering solar:
✅ Replace the roof first ✅ Then install solar on the new roof ✅ Solar racking penetrations are made in NEW shingles, not old ones ✅ No future coordination needed
Option 2: Replace Roof DURING Solar Lifetime
This is the hard case. Your roof needs replacement but solar is already up.
Step 1: Find your solar contract. Many residential solar contracts (especially leases and PPAs) include language about who pays for removal and reinstallation if the roof needs replacement.
Step 2: Get the solar installer to remove the panels. This is usually done by the original installer or their service partner. Cost varies. Some installers offer the service at a discount; others charge full removal/reinstall pricing.
Step 3: Roof replacement. Standard tear-off and reroof. The footing/racking removal points need to be patched and flashed.
Step 4: Solar reinstall. Solar installer comes back to remount panels on the new roof. New flashing, new sealing.
Step 5: System check. Solar contractor verifies system performance and re-files for the production incentive period (if applicable).
Lead Times to Coordinate
- Solar removal: 1-3 days
Total: 4-8 weeks from start to back online.
MA-Specific Considerations
SMART (Solar Massachusetts Renewable Target) program: Production-based incentive. If your panels are down for an extended period, you lose some incentive. Coordinate quickly.
Roof warranty implications: Major roofing manufacturers (GAF, CertainTeed) often have provisions for solar penetrations. Choose a roofer who is familiar with these requirements.
Solar warranty implications: Many solar warranties require professional removal and reinstall. DIY removal can void the panel warranty.
Who Pays?
Depends on contract:
If you own the system outright: You pay for both removal/reinstall and the roof replacement.
If you lease the system: Check the contract. Many lease contracts specify the lessee (homeowner) pays for removal/reinstall if the cause is the underlying roof.
Insurance: If the roof replacement is due to storm damage covered by homeowner insurance, the insurance MAY cover solar removal and reinstall as part of the claim. Check with your adjuster.
Tips for Smooth Coordination
✅ Get the roofer and solar installer talking BEFORE any work starts ✅ Confirm warranty and incentive impacts in writing ✅ Schedule both contractors back-to-back to minimize downtime ✅ Time it for a sunny period (less incentive loss) ✅ Verify system performance after reinstall before signing off
When Solar Should NOT Be Reinstalled
Sometimes the math says replace the panels too:
- Panels over 15 years old (older tech, less efficient)
