IS YOUR HOUSE SUITABLE FOR SOLAR PANELS?

Cleaning your roof is no easy task, however these tips will help you go into the job prepared and armed with the information you need.

How Are Solar Panels Mounted on Your Roof?

It is extremely important to have an expert install solar panels on your roof, as each roof will have different requirements. Below is an overview of common installation methods used in Australia.

Tiled Roof

For single or double storey tiled roofs, tiles are temporarily removed so mounting brackets can be screwed into the structure beneath. The tiles are then reinstalled in their original position. Rails are fitted to the brackets, and solar panels are mounted above the roof surface.

Panels are installed with enough clearance to allow airflow and cooling during hot weather.

Tin / Metal Roof

On metal roofs, existing roof screws are often utilised so additional drilling is not required. Australian standards require existing screws to be replaced with larger fasteners to ensure safety and stability.

All screws and brackets must be professionally fitted and sealed to prevent leaks over time.

Flat Roof

Flat roof installations follow similar principles, however a frame is used to create a pitch or tilt. This ensures optimal solar panel performance.

Does Your Roof Require Maintenance?

Many people install solar panels before ensuring their roof is in a watertight condition. This can create access issues later when maintenance is required.

Different roofing materials require different maintenance approaches.

Metal Roof Replacement or Repair

If you have an older metal roof with leaks, it may be worth considering a full roof replacement. While this has a higher upfront cost compared to maintenance, materials such as Colorbond can last over 50 years when installed correctly.

Additional battens may be installed to reinforce the structure, especially when supporting solar panel systems.

Tiled Roof Maintenance

The condition of a tiled roof depends on its age and previous maintenance.

Terracotta tiled roofs may develop moss or lichen and often require:

  • Roof cleaning
  • High-pressure washing (where appropriate)
  • Re-bedding and re-pointing
  • Broken tile replacement

Cement tiled roofs can also be painted after cleaning and repairs, helping to seal and protect the surface for years to come.

You can also contact your solar provider if you need your solar panels cleaned.
