BrightGridSolar panels can often be installed on older roofs, but the age of the roof should not be considered in isolation. The key question is whether the roof is structurally and physically suitable for the expected installation period.
Consider the remaining roof life
Solar panels can remain on a property for decades. If a roof is approaching the end of its useful life, replacing or repairing the roof before installing solar may be more economical.
What should be inspected?
- Roof covering
- Roof structure
- Existing damage
- Water ingress
- Previous repairs
- Fixing locations
- Roof pitch
- Access requirements
Should you replace the roof before solar?
Not always. If the roof is in good condition and expected to remain suitable for many years, solar may be installed without replacement.
Avoid installing solar twice
If major roof work is likely soon, discuss it with the installer before committing to solar. Removing and reinstalling panels later can create additional costs.
Plan the two projects together
If roofing and solar work are both required, coordinating the projects can simplify access, reduce duplicated labour and create a cleaner final installation.
Check whether your roof is solar-ready
Arrange an assessment before investing in a solar system on an older roof.
Assess My RoofFrequently asked questions
Can solar panels go on a 20 year old roof?
They may be suitable if the roof remains in good condition and has sufficient remaining life.
Should I replace my roof before installing solar?
If major roof replacement is expected soon, completing the roof work first may avoid future panel removal and reinstallation.
Can solar installers repair roofs?
Some installers may coordinate minor works, but major roofing work should be assessed by an appropriate roofing professional.
Do solar panels damage roofs?
A properly designed and installed mounting system should be compatible with the roof construction and weatherproofing requirements.
