The Solar Roof Collision
Installing residential solar panels is an excellent way to lower utility bills and reduce your carbon footprint. However, many solar installers focus solely on electric outputs and solar credits, overlooked the condition of the underlying roof shingles.
Mounting a 25-year solar array over a 15-year-old asphalt roof is a common recipe for high maintenance bills down the road. If the underlying shingles fail early, you'll face substantial costs to address the issue.
The High Cost of Detaching and Re-installing Solar Panels
If your shingles degrade or develop leaks beneath the solar panels, standard roofing crews cannot perform repairs. You must hire a specialized solar company to:
- Safely De-energize and Detach: Disconnect the solar modules from the micro-inverters and remove the panels.
- Store the Hardware: Safely house the modules while the roofing crew completes repairs or replacement.
- Re-install and Commission: Mount the panels back onto the new flashing brackets, rewire the system, and verify the connection.
This detachment process typically adds $3,500 to $6,000 to your roof replacement costs, wiping out years of solar savings.
Extend Shingle Life Before Going Solar
If your roof shingles are more than 8 years old, you should restore or replace them before installing solar panels. Applying a soy-based rejuvenation treatment can add up to 15 years of life to your current shingles, ensuring they last as long as the solar array.
