Drip Edge & Fascia Headerc Q's

[shooon]

Got my trusses up and am starting on my ladders. Just need to figure out how to do my fascia headers.

I've seen it done two different ways, but typically most trusses are 2x6 not 2x4.
What's the most correct way to attach the fascia header? does the inner edge of the fascia header stay flush with the top of the truss? or do you nail it slightly lower so that the bottom edge of the roof sheathing butts up against the outer top edge of the fascia header?

If I do need to go lower and not flush with the fascia header- is there a rule of thumb or measurement to go off of?

There really is no 'right way' in this instance. I've worked around guys that swear one way or the other is correct. I do know that pulling out a speed square to plane the top of the truss to the outside corner of the fascia really ***** on 2' overhangs when you're three stories up.

I like to hold the fascia down about 1/8"-1/4" (depending on the pitch) so the starter sheeting butts into the fascia somewhat close to the middle. It's not important that it be exactly in the middle, the important part is that it's even across the roof. The Goldilocks principle applies.

I also don't snap a line when cutting the tails. I will string line it and use an adjustable rafter square to mark the them. There is usually some amount of variance in the trusses and if you snap a line you will translate that variance to the fascia line.

When putting the fascia board on I always have the sheathing a little past over top of the fascia. I have a scrap piece over hanging then push the the fascia up tight to it getting a tight seal. then the drip edge covering both. I don't like the idea that there is any chance of moisture getting back under plus gives a better nailing edge for the sheathing all the way along the edge.

I agree with Ts...

I run my facia through a table saw so the top matchs the roof pitch, and the sheathing extents to the face of the facia board.

It is about the details..... kudos to n20junkie!!!!

I did the same, ripped a bevel on the fascia board, using 2x8s to compensate somewhat for the loss of height.

A detail we used to use, had a 2x sub fascia so there was meat to fasten the soffit to. The finished soffit was 1x material, usually cedar. The roof deck extended over top of the sub fascia and fascia, and the beveled top on both are a good idea.

I also like to install the drip edge so the drip leg is held off the fascia by 1/8".
