​​Changing Your Roof with Solar Panels: Considerations and Options

At SolarandBatteryCompany.com, one question we encounter every once in a while is, "What happens if I need to change my roof within the next decade?" This concern is particularly relevant for those planning for the long term, contemplating roof replacements, and curious about the implications for their solar installations.

Available Options:

When it comes to changing your roof with solar panels in place, there are primarily two main options to consider.

Option 1 - Remove and Reinstall:

Removing solar panels before replacing the roof and reinstalling them afterward is a viable approach in some cases.

Removing the solar panels from a roof, with hooks still in situ.

This process involves extra costs, primarily for the removal and reinstallation of the system. However, certain expenses, like the scaffold for roofing work, may already be factored into the new roof's cost. Coordinating with roofing professionals can help determine if existing hooks on the rafters can remain or need repositioning during the reinstallation phase.

Over time, materials, rails, and hooks may have slightly warped or expanded, requiring potential replacements. Additionally, an electrical team would be necessary to safely disconnect the solar PV system for either option.

Option 2 - Upgrading or Replacing Panels:

Replacing or upgrading older solar panels while undergoing a roof replacement is an opportunity worth considering. It can result in increased energy production and system longevity. The presence of scaffolding and roofing teams on site might offer cost savings if opting for a new system simultaneously.

Additional Costs and Considerations:

Changing a roof with solar panels typically incurs extra expenses compared to a standard roof replacement. Factors such as labour, potential electrical adjustments, and the need for specialised expertise contribute to the overall costs. Moreover, factors like the weight of the new roof covering and addressing deteriorated components can add to the total expenses.

Professional Guidance:

Seeking advice from reputable solar installation companies or roofing specialists is essential. These professionals can conduct comprehensive assessments, outline necessary steps, and provide estimates for additional costs. Engaging experts experienced in both roofing and solar installations ensures a smoother transition.

Planning and Coordination:

Efficient planning and coordination between roofing contractors and solar installers minimise downtime and disruption to your energy production. Scheduling the roof replacement at an optimal time minimises the impact on your solar energy generation.

Conclusion:

Changing your roof with an existing solar PV system involves careful planning, professional consultation, and understanding potential costs and considerations. With guidance from experts, homeowners can successfully navigate this process and maintain their solar PV system on a new roof or opt for a new installation at a more cost-effective price by aligning both projects. In all likelihood though.
