There are a number of reasons why boral roof tiles are the best to use on minimum pitch roofs.
Minimum pitch for interlocking roof tiles.
Sandtoft s 20 20 tile is renowned not only for its handsome finish but because it comes in at a lower cost than a plain concrete tile.
This minimum pitch is important if tiles are laid below the recommended minimum pitch there is an increased chance of water getting through which can damage the underlay and battens over a prolonged period.
Interlocking clay roof tiles.
There is always a demand to add some finesse to the design of a roof which is what clay material adds in abundance.
In support of design possibilities and to ensure maximum penetration protection the best roof tile to use on minimum pitch roofs is a boral roof tile.
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.
Where the minimum pitch for clay pantiles used to be 30 tiles like the redland cathedral pantile can be pitched as low as 22 5.
All tiles have a minimum roof pitch which is always stated in the manufacturers technical information.
The interlocking technology used on the koramic 401 flemish pantile allows it to go a fraction lower at 22.
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.
