Roofing Permits
Per the Contractor's State License Board you must hold a C39 license and carry current Workers' Compensation insurance to obtain a roofing permit.
If the property has existing photovoltaic panels on the roof a licensed photovoltaic contractor must obtain a permit to re-install the photovoltaic panels back on the roof prior to receiving a final inspection.
Note: The City of Los Altos does not require a tear off inspection on residential pitched roofs.
