BrightGridSolar panels can remain on a roof for decades, so the roof should be suitable for the installation before the system is fitted. A roof assessment helps identify repairs or structural issues that could otherwise become expensive later.
What is checked?
- Roof covering condition
- Visible damage
- Age and expected remaining life
- Roof structure
- Fixing locations
- Water ingress
- Roof pitch
- Access
What if the roof is old?
If a roof is approaching the end of its useful life, installing solar first may create additional costs if the roof later needs replacement. In some cases, roof work should be completed before solar.
Can solar panels be installed on tiled roofs?
Yes. Solar mounting systems are available for many common roof coverings, but the exact fixing method depends on the roof construction and covering.
Think about the next 20 years
Solar panels can operate for decades. The roof underneath them should therefore be considered as part of the long-term project.
Check whether your roof is solar-ready
Assess your roof and installation requirements before investing in solar.

Can solar panels be installed on an old roof?
Possibly, but the roof condition and expected remaining life should be assessed before installation.
Do solar panels damage the roof?
A properly designed and installed mounting system should be designed to protect the roof and manage water correctly.
Should I replace my roof before solar?
If the roof is nearing the end of its useful life, completing roof work first may be more practical than removing and reinstalling solar later.
