Why your roof matters
Solar panels often remain in place for 25 years or more. Your roof should be able to support that timeline. Installing panels on an aging roof may require paying to remove and reinstall the system later — an avoidable cost with the right timing.
How long different roof types typically last
- Asphalt shingles
- Metal roofs
- Tile roofs
- Flat roofing systems
Actual lifespan depends on installation quality, maintenance, weather, and other factors. When in doubt, a professional roof inspection is the most reliable answer.
Warning signs your roof may need attention
- Missing shingles
- Curling shingles
- Leaks
- Soft spots
- Sagging
- Repeated repairs
- Storm damage
If any of these sound familiar, consider a roof inspection before requesting solar proposals.
What happens if you need a new roof after installing solar?
The process usually involves:
- Removing the panels.
- Completing the roofing work.
- Reinstalling the panels.
That adds time, complexity, and cost. When the roof is close to the end of its life, replacing it before installing solar is often the smarter long-term investment.
When waiting makes more sense
If your roof is nearing the end of its life, replacing it before installing solar is often the smarter long-term investment. That advice may seem counterintuitive coming from a solar platform, but it’s exactly the honest guidance we want every homeowner to have.
How SolarFit™ evaluates roof readiness
SolarFit™ asks about:
- Roof type
- Roof age
- Shade
