With more Sydney homeowners turning to renewable energy, solar panels are fast becoming a go-to solution for cutting power bills and embracing sustainability. But before you commit to an installation, there’s one essential step that often gets overlooked; checking the condition of your roof.
At STS Plumbing, we regularly work with homeowners who are preparing to install solar. Unfortunately, we also see the costly consequences when people skip the roof inspection step and dive straight into installation. From hidden leaks to compromised structures, ignoring your roof’s health before you go solar can turn a smart investment into an expensive headache.
Let’s walk through why a professional roof inspection is a non-negotiable part of the solar planning process, and how STS Plumbing can help you get it right from the start.
Your roof carries more than just panels
It’s easy to get caught up in the benefits of solar. The lower power bills. The sustainability factor. The rebates. But none of that matters if your roof isn’t in top condition. Why? Because your roof isn’t just a backdrop for the panels, it’s the foundation they rely on.
Solar panels typically stay in place for 20–25 years. That means your roof needs to be structurally sound, leak-free, and up to standard to support that long-term load. If it’s not, you could end up having to remove the panels, make repairs, and reinstall them, a process that can cost thousands and potentially void warranties.
Many homeowners don’t realise their roof has issues until the solar panels are already up. By then, it's too late.
What solar companies don’t always mention
Most solar providers are focused on installing your system efficiently and quickly. That’s their job. But not all will thoroughly assess whether your roof is ready. If they do a surface-level check or skip this step altogether, you could be left with problems that only show up once it rains, or worse, when water starts pooling inside your ceiling.
If your roof is more than 10–15 years old, hasn’t had recent maintenance, or has seen heavy weather, it's worth booking an independent inspection with a licensed roof plumber. That’s where we come in.
Why a professional roof inspection matters
When you book a pre-solar inspection with STS Plumbing, we’re not just doing a quick once-over. We carry out a thorough roof and gutter assessment to make sure your home is solar-ready and protected for the long term.
Here’s what we look for:
- Roof integrity: Is the structure solid enough to carry the panels over time? We check for cracked tiles, loose sheeting, and signs of previous damage or repairs.
- Waterproofing: Any existing leaks or weaknesses in the membrane or flashing will need attention before panels go in. Otherwise, they’ll be harder to fix later.
- Gutters and fascia: Are your gutters clean, undamaged and flowing properly? Damaged or blocked gutters can lead to water overflow, which may be worsened by panel brackets or roof shading.
- Drainage flow: Sometimes panels can affect how water runs off your roof. We check that drainage won't be disrupted or cause pooling.
If we find issues, we’ll explain what needs fixing and provide a clear, no-fuss quote for the work.
The hidden costs of skipping an inspection
We get it, when you're excited about going solar, it’s tempting to push forward. But here’s what we’ve seen happen when inspections are skipped:
- Leaks into ceiling insulation that go unnoticed until mould or sagging appears
- Internal water damage that requires costly repair to gyprock, flooring or paintwork
- Panel removal costs if roofing repairs are needed post-install
- Voided warranties from both your roof contractor and your solar installer
- Frustration and delays when installation gets postponed for emergency repair
Many of these issues could have been prevented with a single, affordable check.

Frequently Asked Questions
Do I need a roof inspection even if my roof looks fine?
Yes. Many problems (like internal leaks or compromised flashing) aren’t visible from the ground or without specialist knowledge.
Is this inspection different from what the solar company offers?
Yes. Solar companies focus on panel placement and system efficiency, not necessarily roof condition. Our inspection focuses specifically on roofing health.
How long does an inspection take?
Usually between 1–2 hours, depending on the size and accessibility of your roof.
What if repairs are needed?
We’ll provide a clear quote and timeframe. Most minor works can be done quickly so your solar plans stay on track.
