Eaves Trays - Why do mine have to be different??

[WHY_I_DIY_87]

Ok so

im re-roofing and doing the soffits and fascias at the same time. If ripped off all the old ones and started by replacing all the rotted rafter legs (feet/noggins??) To fix the new soffits and fascias to..... And herein lies the problem.....

The rafter legs/feet/noggins whatever they are called, protrude about 200mm out horizonatally from the bottom of the rafters. The eaves row of tiles need to have an amount of "tile kick". From what I understand to slow the flow of water to the gutter... which i need to maintain to make everything sit how the eaves row old tiles sat.

The new eaves row of tiles will sit at the right angle from the first batten to the top of the new fascia and maintain the same angle as before, but the eaves trays have nothing to give them any angle. They just arent deep enough to reach the angle of the rafters so they are sitting basically flat which is no good for the job they are designed to do!

I basically think I should have cut a step into the rafter feet to allow them to sit up at an angle. Now I think ill have to add more material onto them to give them some height at the back or put an extra batten under them to sit on, although this is a massive waste of material. They have to be at least 15 degrees, according to the tds.

Any ideas?

Thanks

The bottom tile/tray shouldn't be anywhere near flat, it'll need a run on it, however you achieve that.

OP,
From what you show and say its difficult to work out what exactly you have done to the original hip roof, & how to advise you.
I dont see any signs of a felt membrane or eaves trays?
You intend to have eaves soffits - maybe you previously had a sprocketed roof?
Presumably, you lifted a couple of tile bottom courses - to help you then you would need to lift at least the same bottom courses to show how the roof has been framed at the eaves?
FWIW: near a lookout(?) theres a gap filled with vegetation? What is the it?

You need to cut those joists/ceiling ties to the same plane as your rafters, then attach your fascia, making sure you set it to the correct kick for the first course of tiles.

Ok so i have progressed slightly. The joist are the same length as the old ones and the fascia is just as thick so the overall length from wall to the front of the fascia is the same as it was previously. The height of the joist on the other hand....they were 120mm which has to be cut to 105mm to allow 15mm for the height of the eaves tray. This leaves the tile sitting just barely above the minimum of 15degrees. Which it actually needs 100mm headlap at that angle..

I have fitted some eaves trays and they sit at an ok angle but i think they need extra support in between joists. Then when then membrane goes on just hope it doesnt sag which could cause pooling before the trays.

I have no idea what a sprocketed roof is im afraid.

No that is just the first row pushed back that will sit on the new fascia tray.

That vegetation is the 70 year old bitumen roof memebrane im replacing it just falls apart when you touch it

Why didn't you just emulate what was there before?

Because its 70 years old and falling to peices. Did you even read what was said i think not
