Also I was wondering what sort of success people have had using wood hardener to repair house timber (untreated pine), not load bearing of course? I have discovered rain getting into a soffit/eave has damaged some timber and plan to treat it with wood hardener, then putty, then screw in a new cement sheet as the old one just crumbled when I removed it, due to water damage I suspect.

I have used hardener and then a 2 part builders bog, followed by surface coating with exterior varnish, to patch up dry rot in Oregon timber in a pergola. It has last about 8 years, but it is not load bearing. The patch could fall out if there was downward force.
As your requirement is load bearing (cement sheet) I recommend supporting the rafter with a prop, cutting the rot out, and replacing the rotten part with a new section of rafter. Use a steel sleeve and fasten with nuts and bolts. It will then last as long as the rest of the eave.
best wishes,

I have used builders bog turbo indoors when I changed my garage door around, to fill the hinge and lock recesses and screw holes, it was easy to use and is still good after a few years. I wasn't sure how it would stick to wood hardener, which is why I'm going to have to putty, but it doesn't have to be really strong as I still have strength in the side timbers as only the end one under a fascia board really half rotted away. My yachting mate said to fibreglass it all, but he loves that stuff, built his own fridge/freezer and dinghy out of it. I might still paint it all in bituminous/creosote paint to protect it if water gets in again, although I think I've discovered the three leak points.
