Maui Roof Repair With an Existing Solar Array

Document the Existing Solar Agreement

Hawaiian Electric directs customers with existing solar agreements to submit amendments when adding, removing, or replacing equipment, with review of proposed changes. Ask the utility and solar contractor how your particular removal and reinstallation should be handled, especially if damaged equipment will be replaced with a different model or capacity.

Find the original agreement, equipment schedule, warranties, and monitoring records. Check whether the panels are owned, leased, or subject to another service arrangement before authorizing work. Ask who will obtain any owner or agreement-holder consent. Keep a baseline record of system operation, but do not assume normal monitoring data proves that the roof attachments are sound.

Confirm Maui County’s Permit Scope

Maui County’s electrical-permit guidance includes renewable-energy systems and notes that photovoltaic projects may also need separate fire review. Its building-permit guidance covers alterations and repairs, with review depending on the work and location. Present the combined roofing and electrical scope so each trade understands which permits and inspections apply.

Describe whether the array will return unchanged, move to another roof area, or receive replacement modules, racking, wiring, or storage equipment. Ask what structural documentation is needed for the proposed mounting arrangement. Have one named person track the permit questions and circulate decisions to both crews; separate estimates should not produce conflicting assumptions about responsibility.

Plan Safe Removal and a Weatherproof Handoff

Hawaiian Electric’s solar safety guidance warns homeowners against removing or repairing rooftop equipment themselves and notes that a system can still produce dangerous voltage when utility power is out. Use an appropriately qualified solar or electrical crew for isolation and handling. Turning off household power is not a homeowner clearance to dismantle panels.

Agree where panels and components will be stored, how they will be labeled, and who documents existing damage. Ask the roofer to inspect exposed attachment areas before closing them. Include temporary weather protection if the trades cannot work consecutively, and decide who responds if rain enters during the interval. Photograph concealed flashing and repairs before the array makes those locations difficult to inspect again.

Require a Complete Return-to-Service Record

The final proposal should distinguish roof work, array removal, replacement parts, reinstallation, testing, and restoration of monitoring. Ask each contractor to explain warranty coverage at roof penetrations and the process for resolving a later leak. A broad promise that both trades stand behind the job is less useful than named responsibilities and written terms.

Before closeout, request inspection records, updated equipment details, any required utility approval, and the installer’s commissioning results. Confirm who verifies that monitoring is reporting properly and explains any changed settings to the household. Keep the original and revised array layouts together. If a component remains unavailable, document the incomplete scope and temporary condition without representing the system as fully restored. Keep the final roof layout with the electrical documentation for future maintenance.
