Let’s start with your property
Start with the right question.
Solar equipment and the roof beneath it should be planned together. Early coordination helps clarify roof access, attachment details and who is responsible for each part of the work.
Connect this guide with Whanganui roof replacement to explore the assessment, work boundaries and practical questions for your property.
A clear scope. The right questions.
A considered next step.
01 /
Understand the roof condition first
Before a new solar installation, discuss the covering, junctions and fixings with a suitable roofing assessor. Explain known leaks or planned replacement work. This gives the solar installer a clearer brief and helps you consider whether roofing should happen before equipment is installed.
02 /
Share the equipment layout
Provide the proposed solar layout to the person responsible for the roof specification. Ask how supports, cable routes and any openings will be coordinated with the roofing system. Structural and installation requirements need competent design and product-specific checks for the actual property.
03 /
Assign removal and reinstatement responsibilities
For re-roofing beneath existing panels, clarify who isolates the equipment, removes it, stores it and returns it to service. Coordinate those tasks with the appropriate solar and electrical professionals. Do not assume the roofing quote includes them because the panels are attached to the roof.
- Isolation and removal
- Temporary storage
- Reinstallation and checks before use
04 /
Agree future access and care
Discuss how the roof, gutters and equipment will remain accessible for inspection and maintenance. Ask who to contact if a leak appears near a support or cable route. Keep roof and solar care instructions together, and have responsibilities explained wherever their requirements overlap.
05 /
Keep one coordinated programme
Material deliveries, roof access, temporary protection and equipment work need compatible dates, with a contact responsible for changes. Agree the sequence before booking separate trades. Retain the roof specification and solar installation records so future work begins with information about both systems.
Keep the next step informed

General planning information. Product and site-specific requirements should be checked for the actual work.
Can panels go back onto a replacement roof?
Have the solar installer and roofing team assess the proposed arrangement. Existing mounting details may not suit a different roof system.
Can roofing begin while panels remain connected?
Agree equipment isolation and site controls with the responsible professionals before work begins. Do not disconnect or alter electrical equipment yourself.
