Detail for slightly protruding/flush eaves

Baltrasna2013

Hello,
I am proposing to use the following detail for a slightly protruding/flush eaves on a new build house. The final appaerance will be a slightly protruding wall at eaves level with a rendered finish. There will be no fascia or soffit.

The proposed flush eaves detail is marine ply fixed to end of rafters, covered with a breathable membrane or DPC, plastering mesh fixed over dpc, render over plastering mesh.

Has anyone used this detail previously.Does it work wrt to preventing moisture getting into marine ply. Has anyone had any cracking of render as a result of using this detail. Any suggestions/recommendations welcome on best way to approach this detail

Alternatives may be to use a cement board or a pvc board covered with render any recommendations wrt approach also welcome.
Thanks.

Hi Baltrasna2013,
I have just constructed exactly as you have described (using good quality breather membrane, not DPC). The architects who designed my house recommended this build up, and my current engineer feels this is a good method.

The house is being plastered at the moment. My plasterers feel I should have no problem with plaster cracking, (which was one of my fears).

I intend to fix my eves directly to the plastered wall... Is this what you had intended? I have not really researched if this is good practice...

I hope my info. was of some help...

Thanks Bmad I am just doing the same detail now. I am going to render over my eaves board but otherwise I think detail is the same. Having the fascia board over the render means it will be easier to replace in years to come but otherwise the detail sounds similar.thanks again for your advice on this'

HI, Have you any pictures of the eaves detail, during construction? Just to get a clearer picture of what you are describing and where the last rafter is relative to the external wall.

Thanks!

I'd like to see some pics as well if you have them.

I put the last rafter in the cavity, treated it and wrapped it in DPC. I used a no.2 slate trim on the gables.
