Should I get a new roof before installing solar panels?

Short answerOften yes, if your roof is more than halfway through its life. Removing and reinstalling panels later adds a separate cost and coordination, so replacing first avoids doing it twice. Ask a roofer how many years your roof has left, then coordinate with the solar installer. Get a free written estimate for the roof.

How do I know if my roof will outlast the panels?

Compare the roof's age to its expected life. InterNACHI estimates about 20 years for 3-tab shingles, 30 for architectural shingles and 40 to 80 for metal (InterNACHI). If the roof will need replacing while the panels are still working, replace first.

What does removing panels later involve?

A solar-licensed contractor removes and reinstalls the panels, with electrical work and sometimes a separate permit; see solar panel removal for a reroof.

How do I coordinate the two contractors?

Get the roofer and installer to agree on attachment flashing, who warrants roof penetrations and the order of work. CSLB has separate classifications for roofing (C-39) and solar (CSLB C-39).

What roof is best under solar?

Long-life roofs reduce the chance of removing panels again: architectural shingles, metal or tile with new underlayment. See metal vs. shingles.
