What is slate roofing?
Slate is a natural stone quarried and cut into tile-like pieces with a slightly rugged texture. One advantage of slate roofing for historic buildings is that it helps maintain the classic appearance of an older property.
Most slate is grey. However, as a naturally occurring material, it can vary in colour.
Installing slate roofing in the UK is a skilled craft. Slates are fitted to the roof with pegs and nails, so accurate holes must be punched into them before they're fitted.
What is tile roofing?
Tile roofing is made from either concrete or clay and is available in a wide variety of designs and colours. For this reason, tile roofing options for UK homes are wide and varied - it's easy to find a style to suit the architecture of your home.
Due to the selection of formats and sizes, tiles are more versatile, making it easier to work around skylights or chimneys, for example.
While tile roofs still require a skilled professional for installation, the process is often quicker and less costly.
Key differences between slate and tile roofing
A new roof is a major investment in your home, and there are several key aspects to compare when selecting the best type of roofing material, including:
How long the roof will last
What it will look like
Whether the roofing material is environmentally-friendly
The average cost of repairs or maintenance
Considerations for the installation process
...And how much it will cost
We look at these factors below, comparing slate vs tile roofing.
1. Slate vs tile roof: Durability
Slate
Slate is well-known as an incredibly durable roofing material - it can last 100 years or more if it's well-maintained.
It is resistant to extreme weather conditions and temperature changes; the durability of slate roofs in rainy climates is a standout feature. This is one of the top reasons why many UK homeowners choose this roofing material.
Tile
What about tile? Can tile roofs handle UK winter conditions as well?
Tile is also a super durable roofing option. However, it can crack more easily under impact.
Depending on the quality of the tile and installation, a tile roof should last 50-70 years.
2. Aesthetics
Slate
The natural beauty of slate is a major part of its appeal. It undoubtedly creates a charming, classic feel to a home, especially on an older property.
Tile
Tile offers a wider variety of colours, shapes, and finishes. Whether you want a Mediterranean terracotta look or a modern concrete-style tile, tile roofing offers versatility.
The other benefit of tile roofing is that it can be used on a pitch as low as 15 degrees, whereas slate can only be used down to a 25 degree pitch.
3. Environmental credentials
Slate
Slate is a natural, long-lasting material with a lower environmental impact than man-made alternatives.
Tile
Wondering whether tile roofs are environmentally friendly? Clay and concrete tiles are made from natural materials but use more energy (than slate) during production.
They don't last as long as slate, but they are recyclable at the end of their life.
4. Repairs and maintenance costs for tile vs slate roofing
Slate
Once installed, the cost of maintaining a slate roof should be minimal, especially if you opt for good-quality slate. Because of its durability, slate is resistant to rot and insect damage.
It's much more likely that the slate tile fixings will need replacing well before the tiles themselves - the nails can corrode, leading to tiles slipping or splitting.
On average, slate roof repair costs tend to be between £150 - £220 per m².
Tile
Tile roofing maintenance will generally be for broken, missing, or loose tiles.
Glancing every now and again to check the condition of your roof can help quickly identify any minor issues before they become more serious and costly.
Many homeowners choose to pay for a professional roof inspection to make sure everything is ship-shape.
For a rough idea of cost, clay tile replacement is normally in the region of £110 - £160 per m².

5. Structural requirements and installation
Slate
Slate is heavier than clay tile, but the weight of slate and concrete can be comparable
If opting for a slate roof, you should arrange for a structural assessment to make sure your roof can handle the weight
Installing a slate roof is more complex and time-consuming, requiring specialist tools and techniques
Tile
Some homes may still need reinforcement to accommodate heavier clay or concrete tiles
Installing a tile roof is generally more straightforward and quicker, which can make it less costly
Slate vs tile roof cost (UK)
When comparing a slate vs tile roof, cost is a key consideration. Is slate cheaper than tile? Let's take a look...
How much does a slate roof cost to install in the UK?

Tile roof cost comparison
Generally speaking, tile roofing is less expensive than slate. However, this can depend on the quality of the tile you select.
