@Darcey,
Quote:once I've taken off the soffit and fascia to get at the truss, how do I get the soffit and fascia back on- would I have to cut a hole through the soffit or is there a better way to get this done?
Once you have taken them off, putting them back on shouldnt be that difficult.
You would need to replace the facia board (usually a 1x6 or a 2x6).
You can do that by simply nailing it to the exposed ende os the roof trusses.
You then need to put the soffit back on.
Do that by getting a 2 foot long level, marking the wall at the point where the level shows a level connection with the wall (hole the level against the bottom of the fascia board, touch the wall, and move the level up or down till you get a level bubble).
Do that at both ends of the fascia board, then get a chalk line and mark a line so you know where level is.
Then get some "F channel" (it looks like the letter F) and nail it up above but touching that line.
Nail it up so the "F" is upside down.
Slide one side of the soffett into the F channel, and nail the other end to the fascia board. Do this all the way down the soffit and fascia.
AFTER you do that, you can nail the fascia board cover back up, then you can rehang or hang any gutters you want to put up.
Depending on the length of the fascia and soffits, it should be a simple weekend project to rehang the soffit and fascia.
