What materials do I have on my roof?
The type of flashing you will need for your roof window is determined by what kind of material you have on your existing roof. Here are the most common roof materials and how certain flashings work with them.
Interlocking tiles
Most interlocking tiles are made from either concrete or clay and come in a variety of shapes, sizes and colours.
Roof window flashings should work with most types of interlocking tiles, although manufacturers tend to specialise in a few specific flashing options to meet specific tile designs and thicknesses.
Brands such FAKRO design their flashings to be compatible with their own roof windows only and suitable up to a certain mm of tile thickness. The bottom flashing aprons accommodate the change in height, depending on the thickness of the tile.
Slates
Slates come in two varieties: natural and man-made. Although predominantly grey in colour, slates come in a variety of shades, as well as different textures and patterns.
Unlike tiles, where profiles can reach up to 120mm in thickness, slates are thinner in appearance and will usually not be more than 8mm thick. If you have measured what you believe to be a state and have found it to be thicker than 8mm, it is likely a tile in disguise.
Certain roofs in Scotland are laid with a thick stone slab which might require a tile flashing rather than slate.
The majority of slate flashings are compatible with most types of slate.
FAKRO’s slate flashing kits designed to ensure your window fits snug with your roof at the same time as ensuring your home is completely protected from the elements, whatever the weather
Plain tiles
Though plain titles might heavily resemble interlocking titles from a distance, upon closer inspection you will see that they are a lot slender in appearance with a maximum thickness of 16mm.
Although roof windows can be securely fitted to plain titles with the help of most tile flashing kits, specific plain tile flashing kits are available from FAKRO
Roof pitch and maximum profile allowed for each flashing is specified on the product descriptions of our entire range of plain tile flashings.
What is the pitch of my roof?
Knowing the pitch of your roof is a key piece of information when choosing which flashing you need to go for.
Some flashings will only work from a minimum pitch, such as 20°, but the recommended minimum pitch for installation of a roof window is 15°.
To work out the pitch of your roof, you will need to do two important measurements. The first is to measure the run. The run is the horizontal distance of your roof and runs from the peak of your roof to the wall. You will then need to measure the rise. This is the height of your roof and is measured from the wall of your home to the peak of your roof.
Once you have these two measurements, you should follow the equation- Roof pitch= 1 ÷ Tangent (Rise ÷ Run)
Always ensure that you or whoever might be carrying out the measurements, are being safe at all times. Alternatively, there are apps such as Pitch Gauge that use your camera to calculate the pitch of your roof for you.
