What Is the Minimum Pitch for Timber Shakes?
The minimum roof pitch for shingles is 14 degrees and the minimum pitch for shakes is 20 degrees with a gauge of 190mm. At these low pitches (14-22 degrees), care must be taken and a water impermeable, vapour permeable underlay MUST be used underneath, with a ventilated space between the membrane and the shingles. At these pitches there is a possibility of some water penetration.
