I am building a small extension to my house and now have the Pole and Wall plates in position. I have temporarily dropped a Rafter on and the Pitch is 18.7 deg according to the App on my phone.
I will be using a smooth Marley Modern or similar tile which are OK down to 17.5 deg with 100mm headlap.
I have notched the Pole plate end of the Rafter by just 23 % to get as much height there as possible, and the Pole plate is as high as it can go on the wall. So if possible I am looking at ways of dropping the Wall plate end of the Rafter to give more Pitch.
Although 18.7 is within tolerance for the tiles I am wondering if I can get more pitch by fastening the Rafters flush to the wall plate with joist hangers instead of cutting a Birdsmouth and running them over the wall plate. I am not having Soffits so the Fascia board will be flush with the wall in any case.
Is this possible and if so how will I hang the first row of tiles, ie batten direct on the wall plate ?
Or should I just stick with 18.7 degrees ?
thanks
