Quick answer
The practical explanation
If the roof is near the end of its service life or has unresolved damage, addressing it before solar can avoid removing and reinstalling the array soon afterward. A roof in good condition may not need replacement simply because solar is being added.
What to know
Three points to keep in mind
- Have the roof condition evaluated before finalizing the array.
- Ask who is responsible if roof work is needed later.
- Coordinate roofing and solar details so flashing, mounting, and warranties are understood.
For your home
A site-specific answer still matters
Solar results and service needs depend on the roof, equipment, shade, household electricity use, utility requirements, and the condition of the existing system. Use this guide as a starting point, then have the property and equipment evaluated before making a major decision.
