What is the minimum pitch for a roof tile or slate?

All tiles and slates have a minimum roof pitch which is set out in order to protect the roof from water penetration. The minimum pitch for each product can be found in the table below and in the product brochure or within the products pages. Some tiles and slates incorporate design features allowing them to be laid at a low minimum pitch. Low pitches are often found on extensions to properties where the angle of the roof is limited due to obstructions such as second floor windows.
