Supporting eave tiles on door canopy

[tractor-pete]

I'm about to make a small door canopy 60cm x 90cm on each side/slope.

There are 3 rafters at 30cm spacings. The eave slate will be attached to a batten, but what will support the bottom of the slate, as there is no bottom batten?

I could add an extra batten but it will raise the eave slate alot.

I thought about using a cloaking soffit strip horizontally which would support it but not sure it's strong enough.

I've also realised from underneath everyone will just see the breathable membrane... So is there something better??

If I cover it with ply/oab first then there'll be no natural gap between the rafters for the membrane to sag and allow for water run off... So guess I'd need to add ply, then vertical battens and then horizotal battens... But then the slates will be about 60cm (9mm ply, 25cm + 25cm) away from the original rafter and the verging mortar will look ridiculous.

Please help!! I'm definitely over thinking it now haha

Fascia board or a fillet kicker.

Something like this?

Eaves Felt Support Tray

• Prevents felt from sagging at eaves level and subsequent ponding of water• Eliminates the need to strip a large section of roof to replace old, damaged felt• Fits in new build or refurbishment situations

For fascia boards, which is better PVC or the MDF ones?

Does the membrane go over or under the fascia/kicker?

Under, or it will pool right?

OP,
You will need to set your fascia at the correct height to pick up the eaves tiles.
The roofing felt goes over the plastic, eaves felt support tray.

Just trealised...How do I align the eave slate and first row, if theres no bottom eave batten?

Do I need to just raise the fascia up enough, so the slates are all on the same plane?

I was looking at the porch at the front of our house (which is enclosed/dry, rather than open), but seems like use a batten at the eave edge under the slate... presumably to lift the eave slate, so it meets the first eave slate.

But there's a huge gap.

So there's the top-eave slate, under-eave slate, cement board, felt, felt-support-tray, batten and fascia...

Is this a bit overkill or normal?

Forget the felt! its not needed for what you are doing.

So I'd look up and just see the battens slates from underneath? Nothing else ?

Yes, it's not so difficult if you use the materials themselves to guide you; lay the bottom slate or tile so that it projects 50 to 70mm over where the face of the fascia board will be and nail your batten on. Set the next batten at the relevant distance for how far you need to go to reach the top row and have it land in the right place, then nail another batten on the same distance again. You now have 3 battens fitted
Place the bottom tile and the two above it, place a straightedge on top of the tiles then bring the facsimile board up and lift the bottom tile with it until all tiles lie on the same plane/have the same angle. That's where you nail the fascia on. If after this you feel that it wouldn't adequately support the bottom row you do have the option of filling in behind it to the same height with a couple of battens or rip of wood the right thickness

So I'd look up and just see the battens slates from underneath? Nothing else ?

Er, you could .. but most folk would probably put something a bit more decorative there like wood or pvc cladding, but you could leave a nice place for the wildlife to nest..

Why is the felt not needed for a porch?

Brill, thanks!

What kind of fascia would you use? uPVC? Or can I use a piece of wood primed/painted? It needs to be quite thick, 9-12mm to support it properly I guess.
