Replace part of fasciaboard

[Woooody]

Hi,
The end of a wind board is rotten and needs to be replaced.
How is this done in the smoothest and best way?
See image for proposal.
Alternative 1:
Bevel cut with a circular saw to then screw the new part into the old one + screw in the overlap between the boards including into the beam if possible (the dots in the image).
Alternative 2:
Cut straight with a circular saw and then screw the new part into the overlap between the boards including into the beam if possible (the dots in the image).

Thank you in advance!

Why not do it properly and replace the entire fascia board?

I agree with @fribygg.
Replace the whole thing.

 

[Woooody]

It is only an extremely small part of the vindskiva that is rotten, so I would prefer not to put in more work than necessary.

It's just a very small part of the fascia board that is rotten, so I prefer not to put more work into it than necessary.

That's why it's good to do it properly while you're already messing around.

Only a very small part of the fascia board is rotten, so I would prefer not to do more work than necessary.

It is insignificantly less work to set up scaffolding on the entire gable if you do it now and significantly cheaper to only rent scaffolding once now compared to having to rent it again in maybe 10 years when the joint you are planning has rotted again.

If it is that bad, if the bargeboard extends past the gutter you can cut it to length at half the gutter without shame.

How much is bad, if the windboard goes past the gutter, you can cut the length at half the gutter without shame

A good idea, but unfortunately, more than that is rotten.

Alternative 2 then, but I would have offset the seams by 50 cm, more on the top one of course.

I would like to make a small protest against those who say that only replacing the whole thing is valid, because we don't know the circumstances. It might be that the outermost bit is easy to fix from a ladder and that the rest of the gable will need repainting in a few years, with all that entails in terms of scaffolding/lift, etc.

I replaced the last meter on mine once. I sawed at ninety degrees. (The windskiva consisted of two boards, so I made the cuts with a decimeter in between.) Prime the end grain well with base oil and paint. It held up well for several years until it was time to repaint the whole house next time.

There are those who have fascia boards in 2 parts/joined from the beginning, that's how it was on my old house.

There are those who have bargeboards in 2 parts/jointed from the beginning, like it was on my old house

Not uncommon with joints, but something you preferably address as it tends to become unsightly and rot.

 

[C.Ö]

It's not uncommon to have a seam, but it's something you'd prefer to fix since it tends to become ugly and rot.

I thought it was good since I only needed to replace a part. But of course, a whole one is the nicest.

Even I think you can, with a clear conscience, refrain from replacing everything. Joints often occur anyway when building new. The simplest and best joint is often to screw a board about 60 cm, on the back of the fascia board. About 30 cm on the existing part, and 30 cm to screw the new part into.

Joining is often done anyway, when building new.

When building new, you should preferably order sufficiently long timber so that you can install the weatherboards without joints. I believe, for example, Derome cuts 8m lengths.
