The cost of a slate roof is typically between $100 and $300 per square metre. Slate roofing cost varies on factors such as the type of slate, roof size, and complexity of the installation. Slate can be a more expensive option compared to other roofing materials, but its long lifespan and aesthetic can save you money in the long run. Choosing a slate roof can be a worthwhile investment for your home.
Let’s break down the average slate roof costs in Melbourne; from installation to repairs so you can plan your budget effectively.
Slate Roof Costs Breakdown
Slate roof cost is determined by several key factors that influence both the materials and labour required. These cost factors vary based on your roof’s specific needs, including the type of slate used and the size and accessibility of your roof.
Below we break down these cost factors including:
- Type of slate: Imported slate vs. local slate, quality differences.
- Roof size: Larger roofs require more slate materials and labour.
- Roof pitch: Steeper roofs may incur higher installation and safety costs.
- Roof accessibility: Difficult-to-reach roofs can need special equipment such as scaffolding.
- Installation complexity: More intricate roof designs can increase costs.
- Slate Repair vs. Slate restoration vs. Slate replacement: The state of the roof or the presence of any existing damage can determine if you need a repair, a restoration, or complete replacement.
- Structural integrity: If your roof’s structure is compromised, it could mean a full roof replacement rather than repairs.
- Current roof condition: The state of your slate roof will impact the decision of repair, restoration, or replacement. Minor issues can be repaired, while major damage may require a full roof replacement.
How Slate Roof Costs Vary: Type, Size, Pitch, and Accessibility
The cost of a slate roof varies depending on several factors, including:
Type of slate:
High-quality or imported slate, such as Welsh and Spanish slate, can significantly increase cost due to its premium quality and superior durability. Welsh and SPanish slate is known for its longevity, natural beauty, and resistance to harsh weather conditions. Welsh and Spanish slate is an excellent, albeit premium, investment for people seeking a longer-lasting and aesthetically pleasing roof.
Local slate options may be more affordable (therefore a more tempting option), but they might not offer the same level of quality or longevity. For those on a budget, local slates can still provide a durable roofing solution at a lower initial cost.
Size of your slate roof
Larger slate roofs will naturally cost more due to the increased material and labour requirements. The more square metres of slate needed, the higher the material cost. Additionally, a larger roof will require more time and manpower to install, increasing labour costs.
For example, a larger roof may require scaffolding, more precise fitting, and longer installation times. All of these factors contribute to a higher overall cost. The roof’s complexity, such as multiple levels or intricate designs, can also drive costs up. This is particularly common in Melbourne where we work on heritage buildings that can have beautiful yet complex designs.
Roof pitch
Steep roofs may incur higher costs due to the complexity of installation and the additional safety measures required. Installing slate on a steep roof is far more challenging. Steep roof installs require specialised equipment and extra time to ensure proper alignment and secure placement of the slate tiles.
The risk of accidents is higher on sloped roofs, requiring additional safety precautions, such as scaffolding or harnesses. Both of these increase both labour and equipment costs. A steeper pitch can also make access to the roof more difficult, further contributing to the cost.
Roof accessibility
Difficult-to-reach slate roofs may require additional equipment or labour, raising the overall cost. If your roof is particularly high, has a steep slope, or is obstructed by trees or other structures, the installation or repair process becomes more labour-intensive.
To safely reach and work on these roofs, scaffolding, ladders, or even cranes may be needed. Additionally, the extra time required to manoeuvre around obstacles and safely perform the work can lead to higher labour fees.

Cost of Installing Individual Slate Roof Tiles
The installation cost for slate tiles can range from $250 to $500 per square metre. This includes the cost of the slate tiles and the labour required for installation. Slate is a heavier material, so the roof structure might need to be reinforced prior which can increase costs. Additionally, as we discussed above, the complexity of your roof’s design (eg. steepness, accessibility) will affect the price.
How Much to Completely Replace a Slate Roof?
Replacing a slate roof is typically more expensive than installing one from scratch due to the labour involved in first removing the old roof, and then disposing of the materials. The cost for replacement generally starts at $8,000 and can go up depending on the roof’s size and complexity. If your roof has several layers or if there is extensive structural damage, the cost may rise significantly.
How Do I Know If I Need to Replace My Slate Roof, or Can I Repair or Restore It?
Deciding whether to replace, repair, or restore your slate roof depends on several factors, including the extent of damage, the roof’s age, and the overall condition of the slate tiles. Here’s how you can tell the difference:
- Slate Repairs are typically sufficient if only a few tiles are damaged, there are small leaks, or if minor issues like cracked flashing need attention. These fixes are affordable and can extend the life of your roof for several more years.
- Slate Restoration is a good option if your slate roof is aging but still structurally sound. This may include cleaning or removing moss, re-pointing, replacing a small number of damaged slate tiles. This can also involve addressing underlying issues like roof flashing. Roof Restoration can add decades to your roof’s lifespan at a fraction of the cost of a full replacement.
- Slate Roof Replacement is necessary when the roof has extensive damage. This includes rotting timbers, larger numbers of broken slate tiles, or when the slates have deteriorated to the point that they no longer protect your home. If the roof structure is compromised or there are more extensive underlying issues, roof replacement may be the best (or only) option.
Understanding the difference between these options can help you make a cost-effective decision. If you’re unsure, we can assess your roof’s condition, discuss the options and provide our recommended best solution. We’ll help you understand whether you can get away with simple slate repairs or need a full restoration or replacement.
Breaking Down Slate Roof Repair Costs
Understanding the individual slate roof repair costs helps understand what to expect for different levels of repair.
Minor Slate Roof Repairs
Minor roof repairs involve fixing small leaks or replacing a single damaged slate. These repairs are generally affordable, costing between $500 and $1,500, depending on the roof’s accessibility and the complexity of the fix. It’s a good idea to address these issues early, as small leaks can develop into more serious problems if left untreated.
Moderate Slate Roof Repairs
Moderate repairs are necessary when multiple slate tiles are damaged or if flashing needs attention. These types of repairs typically cost between $3,000 and $6,000, depending on the extent of the damage and the materials required. Flashing issues can often lead to water infiltration, so timely repairs can save you from costly water damage.
Major Slate Roof Repairs
Major repairs are needed when there is significant damage, such as large-scale slate replacement or structural issues. These repairs can start at $8,000 and may increase depending on the severity of the damage. This type of work often requires specialised labour and expertise, so it’s essential to hire professionals with experience in handling slate roofs.

Factors Affecting Slate Roof Repair Costs
There’s a range of factors that can influence the cost of slate repairs. This can be anything from the extent of the damage to the materials and labour required to get the job done right.
Quality of Slate
The quality of the slate used for your roof plays a major role in the overall cost. High-quality, imported slate can be significantly more expensive than local or lower-grade options. However, investing in higher-quality slate can provide better durability and a longer lifespan, making it a better choice for those looking for a roof that will last for decades.
Slate Roof Accessibility
The ease of access to your roof will impact the cost of both installation and repairs. Roofs that are steep, have multiple levels, or are difficult to access may require special equipment or extra labour, which can increase costs. Roof safety measures, like scaffolding, can also add to the overall price.
Typical Labour Costs for Slate Roofs
Slate roofing requires skilled labour, as the material is delicate and requires precise installation. Professional slate roofers tend to charge more than general roofers, with rates typically ranging from $40 to $90 per hour. The complexity of the job and the time required to complete it will determine the total labour cost.
Is Slate Roofing Worth the Investment?
Slate roofing is a solid investment for people wanting long-term durability and a premium aesthetic. The upfront cost can be higher compared to other roofing materials, but it’s more than offset by the sheer longevity of the slate. A properly installed slate roof can lasting over 100 years. This incredible lifespan means fewer repairs and replacements, ultimately saving you money in the long term. Slate’s timeless beauty not only boosts the curb appeal but also increases market value. Slate can be a smart choice that pays off in both practicality and property value.
