Installing fascia

Hi,

I am installing 1 x fascia boards around my hip roof.

Do you need to leave an expansion gap for the joints? If yes, how wide of a gap?
What kind of joints do you use? 45 deg miter or butt joint?

45 deg miter looks nice and I will only need to use two nails but they are harder for me to cut.
Butt joints are easier to cut but I need four nails at the rafter tails.
I am also posting this on another forum.

Thanks for your help.

So what is the purpose of this comment?

No expansion joints, could do either but butt joint is more robust. Up high you wont see them!

If you are using real wood such as cedar, scarf joints are always preferred because the joint stays together better. But other man made products may need to be butted, gapped and caulked as per the mfg's instructions.

Thank you all for replying.

The comment about me posting the same question in another forum so people who are members in other forums do not get upset when they see the same posting. I remember reading somewhere that some do get upset. I am just trying to get the answers I need to do the best job I can for my home.

I am also using common pine boards.

I will be installing gutters all around but that will come much much later after the re-roofing.

I have primed and painted the rafter tails and 1x lumber.

So fore pine lumber, should be a gap and how wide. I read in my search someone said that wood don't contrast and expand longitudinally so no gap is needed. Some one else said all wood expand and contrast.

What do you fill the gap with? caulk or putty, which kind?
Flexible caulk like DAP Alex Flex Moulding and Trim or Alex Flex Spackling? Both are flexible for movements of wood.

Treat pine the same as cedar. (Both are wood, right?) Scarf with no expansion joints. Wood glue the scarf joints and corner miters with Titebond III. There should not be any gaps to caulk.

Thank you.

I have to keep in mind to use Titebond III.

Thank you all for your help.

A few days ago I finished installing fascia boards for the part of the roof I am working on and will continue the process after I am done re-roofing this area.
