When you’re house hunting, it’s easy to get caught up in the kitchen, the size of the bedrooms, or whether the garden gets enough sun. But one of the most important things you should check is often right above your head … the roof. A good one protects everything beneath it, a bad one can quickly become an expensive problem.
This article from MZ Roof Logic, specialists in metal and bushfire-compliant roofing across Sydney, explains what to look out for when buying a home, and what to keep in mind if you’re planning renovations in bushfire-prone areas.
Checking the Roof Before You Buy
Before signing anything, take a moment to look up. Better still, have a roofing professional inspect the property. Things worth paying attention to include:
- Age of the roof – metal and tiled roofs generally last a minimum of 25 to 30 years. If the roof is reaching that age, you may be due for a replacement.
- Obvious damage – missing tiles, rust spots, sagging, or water stains inside the house are all warning signs.
- Gutters and drainage – broken or clogged gutters can cause water to back up and damage the house.
- Insulation and airflow – a roof should help keep the home comfortable and free from mould.
- Local regulations – in many areas, especially where bushfire risk is high, the roof needs to meet strict standards.
Thinking About Renovating? BAL Ratings Matter!
If you’re planning to renovate, extend, or replace the roof, you’ll need to think about BAL (Bushfire Attack Level) ratings.
What Is BAL?
BAL is a rating based on a measurement of how much bushfire risk the property faces … depending on its location and surrounding environment. The classifications start from BAL-LOW (minimal risk) through to BAL-FZ (Flame Zone, highest risk).
Why BAL Ratings Are Important
Your BAL rating affects what materials you can use in the build or renovation. Roofing, flashing, and sarking … the smallest details may need to meet Australian bushfire standards (particularly for BAL-FZ).
But bear in mind, while everything that’s visible on a roof shields from the weather, what lies hidden underneath is your first line of defence against bushfires … the substrate. This is what crucially protects the ceiling cavity from ember entry.
Council Approvals
Most local councils will usually require proof that any new work meets BAL requirements before they will sign it off. That can affect both cost and design, so using a licensed roofer who understands BAL construction standards is vital.
This is because National Construction Codes 2022 require development consent, which stipulates that it must comply with Australian standards, not exempt or complying development.
The Roles in BAL Compliance
It’s also essential to remember that it’s not within a roofer’s jurisdiction to determine what may be deemed compliant in bushfire-prone areas … that’s the role of a bushfire consultant. However, the roofer’s responsibilities are just as crucial … it’s ignorant for a roofer to disregard potential risks and not meet compliance.
Why It’s Worth the Effort to Check the Roof
A new roof is one of the most significant upgrades you can make to your home. If you miss the early signs of damage, or fail to look into your BAL requirements, you could be looking at serious unplanned costs after settlement … or expensive redesigns if the council rejects your plans.
Checking the roof’s condition before you buy, and understanding any compliance duties, gives you the confidence to make an informed decision … and protect your investment long-term.
