Whether you’re installing a new roof or repairing a broken one, you’ll need to cut tiles to the right size if you’re doing it yourself. Depending on the type of roof you’ve chosen, there are different tools and techniques for different materials – and we’ve listed the steps to cut each roof tile material. Read on to find out more.
Equipment for Cutting Tiles
When it comes to DIY jobs, skills and equipment range from cleaning your roof with a brush to completely renovating it. Cutting tiles may seem like a simple job if you’re a confident DIYer, but if you doubt your ability, it’s best to speak to a professional.
To cut tiles yourself, you’ll need one of the following (depending on the tile material and type of cut):
- Tile cutter, best for straight and clean cuts
- Wet saw, best for natural stone tiles
- Angle grinder, best for complex shapes
- Tile nippers, best for irregular cuts
Safety equipment is always vital, no matter your skill level and the tile type.
Can You Cut Tiles Without a Tile Cutter?
Yes, you can cut tiles without a tile cutter. An angle grinder, wet saw, and tile nipper will also work. If you’re unsure about any equipment you’re using, speak to a professional.
Preparing to Cut Tiles
Before cutting tiles, you’ll need to prepare.
- Measure and mark: Firstly, you need to measure the space required and mark the measurements with a pencil so you know where to cut
- Support the tile: Place the tile securely on a stable surface before making any cut.
Tile Cutting Techniques
Below, we’ve explained how to cut tiles – whatever type of tile you have.
How To Cut Concrete Roof Tiles
Concrete roof tiles are highly durable – while they make for long-lasting roofing, it can mean they’re harder to cut and might require a specific process. Generally speaking, the best way to cut concrete tiles is with a wet saw. This method allows for a smooth, straight edge.
For concrete, use a diamond blade, which will last longer than a regular blade.
A wet saw prevents too much dust – which is best to avoid breathing in when cutting concrete.
Even with wet saws, you should wear proper protection to resist breathing in the dust. You should also wear protective gloves and safety glasses.
How To Cut Clay Roof Tiles
Clay – or terracotta – ceramic tiles are very popular. They’re a timeless roofing tile with plenty of curb appeal. However, clay tiles require a specific cutting method.
To cut clay tiles, make a scored line with a knife. Then, snap the tile along the scored edge. If you have thicker clay tiles, you’ll need a slate cutter or stronger tool, like a wet saw, angle grinder, or a Dremel Tool.
How To Cut Slate Roof Tiles
Slate roof tiles are a highly popular choice for many Australian homeowners. Like ceramic tiles, thinner slate roof tiles can be cut by scoring them with a knife and snapping along the scored line for a smooth edge.
However, if you have thicker tiles, you might need a manual tile cutter or saw – but you’ll still want to score the tiles first. Scoring makes it easier to get straight cuts.
If you’re using a saw or angle grinder, make sure you clamp the tile down securely to avoid ruining the slate.
How To Cut Asphalt Shingles
To cut asphalt roof tiles, you’ll need a straight edge (to get a straight line) and a sharp knife. If the knife is sharp enough, it should cut through the asphalt shingle easily in a single stroke. If not, you should be able to score the tile and then bend it back and forth to break it along the marked line.
If you’re cutting more than one tile, a hook blade will serve you better. Hook blades offer a clean cut and stay sharp for longer than regular utility knives. When cutting multiple asphalt shingles to the same size, you can use an angle grinder or circular saw.
Make sure you secure the tiles so they don’t move, ending up in different shapes and sizes. Use the saw to cut along a straight edge, resizing multiple tiles at the same time.
Generally speaking, asphalt is easy to cut. Just take your time and avoid cutting yourself.
How To Cut Composite Roof Tiles
Like asphalt, composite roof tiles are generally easy to cut with a sharp knife. Composite roof tiles, made from recycled plastic or fibreglass, are increasingly popular as a more affordable roofing option. These tiles often imitate wooden or slate roofing tiles but are often easier to cut and maintain – and long-lasting.
As with asphalt shingles, if you’re cutting multiple composite roof tiles, you can use an angle grinder or circular saw to speed up the job.
Which Tiles Are Best for Roofing?
There’s no one-size-fits-all roofing tile; each has its pros and cons. Depending on your budget, local climate, and personal preference, there are plenty of roofing options for different needs.
Indeed, if you plan to install, care, and maintain your roof yourself, you might opt for asphalt or composite shingles that are easy to install and affordable while remaining attractive.
However, if you live in an area with strong winds, heavy rains, and harsh UV rays, you might need a more durable option, like terracotta tiles.
Tips for Installing Roof Tiles
- Start by ensuring the roof structure is sturdy.
- Begin laying tiles from the bottom edge, overlapping each row to prevent leaks, and secure tiles with nails.
- Use a chalk line to keep rows straight.
- Install flashing, taking particular care around protrusions and roof edges.
- Finally, inspect the roof thoroughly after installation and perform regular maintenance checks to keep it in excellent condition.
Cutting Roof Tiles
With the proper preparation, equipment, and safety precautions, the cutting process can be a relatively simple job for anyone with DIY experience. Using a wet saw or angle grinder, you can achieve the desired shape.
