The roof report: Material and condition
A roof report can benefit Australians looking to assess their home’s health. This inspection details the roofing material, such as tiles, metal sheeting, or concrete, and analyses its condition, identifying any damage or signs of wear that might require repair or replacement. With Australia’s diverse climate, a roof report ensures your home is well-protected from the elements.
Roof material compatibility
Different roof materials have varying levels of compatibility with solar panel mounting systems. Here’s a breakdown of common Australian roof materials:
- Tiles (concrete or terracotta): A popular choice, tiled roofs offer excellent durability and can handle the weight of solar panels.
- Metal roofs: Tin or steel roofs, especially those with standing seams, are great for solar due to their lightweight and strong nature.
- Asphalt shingles: These are another compatible option, as long as they are in good condition.
However, some materials require extra attention:
- Slate and wood shake roofs: These may be better for traditional mounting methods due to their delicate nature. Consult a professional for specialised solutions.
- Flat roofs: While solar panels can be installed on flat roofs, special considerations are needed to ensure proper tilt and avoid water pooling.

Roof age and condition
- Leaks and damage: Before installing solar panels, you must address existing leaks or damaged areas on your roof. Waterproofing is crucial to prevent moisture from accumulating under the panels and damaging the roof and the solar system.
- Age and structural integrity: A sound roof is vital for safe and efficient solar panel installation. Your roof should be structurally strong enough to support the additional weight of the panels and mounting system. If your roof is nearing the end of its lifespan (generally 10-25 years depending on the material), it might be wise to address repairs or replacements before installing solar.
Space considerations: Optimising sun exposure
Australians looking to harness the sun’s power with solar panels should consider roof compatibility. Not only is the roof’s material (like metal or tile) important but also its orientation and available space. North-facing roofs in Australia typically capture the most sunlight, while ensuring enough square footage exists to accommodate the desired panel quantity for optimal energy generation.Â
The amount of usable space on your roof directly affects the number of panels you can install, impacting your overall energy generation. Here’s what to think about:
- Roof size: Larger roofs provide more space for panels, allowing for a potentially larger solar system.
- Shading: Shadows from nearby trees, chimneys, or other structures can significantly reduce solar panel efficiency. Analyse your roof’s sun exposure throughout the day to identify the best placement for panels. North-facing roofs in Australia generally receive the most sunlight.
- Usable area: Consider roof features like vents, skylights, and access points that may limit usable space for panels.
What is the best roof configuration for solar panels?
The ideal roof for solar panels faces north in Australia, allowing maximum sun exposure throughout the year. East or west-facing roofs can still be viable options, but their efficiency might be slightly lower. Flat roofs are suitable, but special mounting systems are required to tilt the panels towards the sun for optimal performance.
How much space should be between solar panels and the roof?
Adequate ventilation requires maintaining space between the panels and the roof. This allows heat to dissipate, preventing overheating and ensuring efficient power generation. The recommended space depends on the mounting system, typically 10-15 centimetres.
How do I know how many solar panels will fit on my roof?
Several factors influence the number of panels you can install. These include the usable roof space after considering obstructions like chimneys or skylights, the size and wattage of the chosen panels, and local regulations regarding minimum clearances from boundaries. A solar installer can assess your roof and provide a detailed plan outlining the optimal panel layout.
