Tiling shallow pitch roof @ less than 15deg.

[robh2]

Adding a single storey extension to the rear of my property with a roof pitch that will be below 15deg. the main house has a large flat concrete tile that is not specified for shallow pitches.
My question is: Is there a way to overcome this and use the same tiles as on the house? or do I need to use a tile that is spec'd. to go down to this pitch?
Thanks

Sorry, haven't got a clue!
But, your architect will specify what type.
I also found the customer services guys at Marley were most helpful if you really can't wait.

I think the lowest some roof tiles is 12 degree, if it's lower than this then it may have to be metal sheet tile which can go down to 10 degree pitch.

closing the overlap of tile will help but manufactorer will not guarantee this
