Marley roof tiles minimum pitch.

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. 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. The pitch is crucial in minimising the amount of time it takes for water and debris to clear from the roof. There are some general rules that can be applied to different types of tiles.

It is always better to raise the safety factor of the roof by adding a full course of tiles and increasing the tile headlap evenly on the rafter length. All tiles and slates have a minimum roof pitch which is set out in order to protect the roof from water penetration. In addition to the products available from marley other low pitch roofing options may include fibre cement tiles and natural slate. The minimum pitch and minimum headlap must not be reduced under any circumstance.
