Getting a new roof with solar panels in San Mateo County: what does removal and reinstall add?

Short answerPlan on solar removal and reinstall adding several thousand dollars or more to a San Mateo County reroof, depending on how many panels you have, how they're mounted and how hard the roof is to work on. The electrical side is a solar or electrical contractor's job. Request one estimate that covers both.

Who handles the solar panels during a reroof?

The array is electrical equipment, so a C-46 solar or C-10 electrical contractor should take it down and put it back. Your roofer handles the roof, including flashing the new mounts. Decide early who hires whom, and get it in writing.

What drives the solar removal and reinstall price?

  • How many panels and how they're attached
  • Whether racking, flashings or wiring need replacing
  • Steep pitch, height or a tight lot
  • On-site storage and protection of panels
  • Any permit and inspection for reconnection

What if the system is leased?

Leased and PPA systems belong to the provider, so the agreement decides who may remove them and how much notice is needed. For owned systems, check whether the installer's warranty requires them, or a certified contractor, to do the removal.

Should I replace the roof while the panels are off?

The common mistake is reinstalling panels on a roof with only a few years left. If the roof will need replacing within the panels' remaining life, it usually makes sense to do it now while they're off.

What's different in San Mateo County?

Peninsula arrays range from small systems on Daly City and South San Francisco tract roofs to larger ones on two-story homes in San Mateo, Belmont and Redwood City. Low-slope mid-century roofs often carry tilted racks, and every penetration has to be flashed into the new membrane. On the foggy west side, check the condition of rails and fasteners for corrosion while the array is down. Sites with steep driveways or no side yard need a plan for where panels wait.

How do I get a price?

Ask for one written estimate that covers removal, storage, reroofing, new flashed mounts and reinstall, or two coordinated estimates with clear responsibilities. For your actual price, request a free written estimate: a licensed roofer measures the roof and prices your exact scope.

Frequently asked questions

How long are the panels off the roof?

Usually for the length of the reroof plus scheduling for reinstall and any inspection. Agree on dates with both contractors.

Is solar removal included in a roof quote?

Often not. Ask whether it's included, priced separately or excluded, and get it in writing.

Should I replace corroded racking while the panels are off?

It's the cheapest time to do it. Ask the solar contractor to inspect rails, clamps and fasteners and price any replacement separately.
