You can also estimate a roof pitch by eyeballing it from the ground from the gable side with a level and ruler.
Roof tile pitch guide.
In essence a roof pitch chart is provided as a rough guide usually by a roofing company to help you see what the average roof pitches tend to be.
Traditionally a minimum roof pitch of 20 was recommended in bs 5534 but modern tiles and slates have now been designed for applications as low as 15.
Iv the minimum headlap.
It is uncommon to find a roof below 15 but for those very low pitch applications there are interlocking clay pantiles available suitable for use down to 12 5.
Set out nominal batten spacing.
Monier has developed this guide to provide the designer or the main contractor with specific advice as it relates.
295mm on 38mm x 38mm battens.
355mm it is good tiling practice to check the gauge of all kiln fired clay roof tiles at the site.
Minimum roof pitch18 with sarking and 20 without sarking.
The style of a roof tile will not dictate the pitch it can be used for as this will depend on the actual design.
Composition shingle and tile are most commonly used on residential roofs.
Use two tiles to determine the spacing required for the battens.
Divide the results by the number of 12 inch segments in your level.
Iii the maximum rafter length.
Anything lower than this angle is rare and although there are specific products that can go lower 15 is the most common minimum angle for clay tiles.
Roof type roofing systems will function in different ways which is why they require attachments that are built to integrate with them.
For many years 20 was recommended as the minimum pitch for clay tiles but this has decreased in the modern era down to 15.
For example if you used a 24 inch level and your measurement was 12 inches the pitch in your roof is 6 in 12.
Ii the need for sarking.

In this respect plain roof tiles provide great flexibility as they can be used to suit almost any angle usually above 35.
Usually they come in the form of a roof pitch diagram chart but other times it will be presented to you in a conversion format.
A minimum of a 3 inch overlap is required for the tiles.
At the time of estimation the following information is to be.
More horizontal and vertical lines may be snapped to ensure the roof slates will stay true and plumb throughout installation.
