Wallplate/purlin repair - overhanging eaves

Post by hwood »

Hi,

The house has overhanging eaves and the purlins/wallplates protrude underneath. The bottom right wallplate/purlin had rot (circled in red).

The size was roughly the footprint of a brick. It didn't look too bad from the side/ground. You can't see it from the inside - I think it goes into the top of the attic wall? Is it the 'wallplate'?

It looks like water had wicked in the end grain and rotted the opposite side which was barely attached. There was another piece of wood on top which I don't think was rotten - same size as the overhang framing.

The carpenter said there was nothing to attach a splice to. They have cut both pieces of wood so there is about 2 inches left, sitting underneath the rear framing.

The side now looks like this:

The underside/opposite side like this:

Is this a good and long lasting repair?

Thanks in advance.

Wallplate/purlin repair - overhanging eaves

Not my idea of a fix or good practice, the topper was solid, it should not have been cut; it was doing a job, but did he work off just a ladder or platform?
I doubt anything untoward will happen, but nor would it have, if left with just clean up and treatment except for aesthetics.
Now it is a butt joint held together by a top screw with the bottom screw only a stabilizer!
Nothing easy to rectify now however:-
Others might add comments.

Hi @aeromech I got pushed into making a decision when I was at work about cutting the wood as he wanted to arrange it. He worked off a scaffold but this area is quite close to the platform.

Would one of the timber repair kits for purlins I've seen online work? (I can't post a link). He assured that his repair would be superior..

Spoke to the carpenter he said it's dovetail screwed in with 4 inch screws into the remaining wood (whatever that means). I asked is that where you screw in at an angle he said yes.

Also says it's supported by the fascia?

Even using deeper longer repair plates (S.fix 119JF or better) would be a negative now as it will put more holes in the stub end of the 'Purlin'.
Basically it is just a spacer and not even aligned for aesthetics on bottom surface, I would be ashamed to say it was supported by the fascia because that is a fact, but not correct..

The hard thing is trying to bring it back from the balls up he has made.The stub end is supporting the weight of roof tiles over that span so it is a fair amount and also it is tying it all against winds. Sourcing the right sized timber to replace the stub will be a start and I would be looking at two angle iron lengths cut through the wall and tied to the exiting purlin inside and extending out to provide a strong support for the replacement wood stub to be fixed to. A bit of a faff and scaffold needed but using steel will give the support needed.

As an alternative . Using a piece of timber the same dimensions as the purlin fix with all thread through the face of the facia into the end of the purlin. Sink the end of the allthread below the surface of the facia and cover with a timber plug. A bit out of the usual budget but I have seen this sort of repair with glass fibre rods and resin.
