The effectiveness of the tile or slate to operate at the minimum recommended pitch and lap may be influenced by special circumstances. Guidance on pitch and lap should be obtained from the Technical Advisory Service for the following: Interlocking tiles and slates where the roof slope exceeds 6 metres in length and/or the site is rated to be in a severe exposure category. Double-lap fibre cement slates where the roof slope exceeds 6 metres in length (severe/very severe exposure) and 9 metres in length (sheltered/moderate exposure).
