Fascia flashing for sunroom.

[petersson79]

I'm working on a conservatory now and going to install the fascia boards. But what kind of flashing should I use that goes down and covers against the felt? I bought fascia board fittings (Lindab) today but it didn't feel quite right as they didn't fit particularly tightly.

I'm using double 22s as fascia boards and the flashings I bought were 55 mm before the angle down - is that correct but just too short or is there another type I should use?

Currently working on a sunroom and about to install the bargeboards. But what type of flashings should I use to go down and cover against the roofing felt? I bought bargeboard flashings (Lindab) today, but they didn't feel quite right as they didn't fit very tightly.

I'm using double 22r as bargeboards and the flashings I bought were 55 mm before the bend down - are they correct but just too short, or is it another type I should use?

Or am I making a thinking error and just need to lower the outer overlapping board? What makes me hesitant is:
https://www.bygghemma.se/hus-och-by...4Bnu1qH2L6YkKuYmurrZPP8vhDImL8lgaAkV7EALw_wcB - is the one I bought. However, it states for tile profiles.

But then there is this one for flat roofs.

Which one is correct for a roof with felt?

A fascia board for tile profile is usually used and it doesn't need to be completely tight, you have finished with a triangular strip under the roofing felt, right?

A wind board plate for a tile profile is usually used and it doesn't need to be completely tight. Did you finish with a triangular strip under the roofing felt?

Yep, I have a triangular strip in front and on the sides. I’ll try lowering the outer board to get closer to the roofing felt, and maybe split it a bit if needed. I live in a pretty exposed area with a lot of wind, so I want it as tight against the roofing felt as possible to prevent too much water from being pushed in.

But the first one I linked to is the right one, then?

It might be easier to understand if you post some pictures here. A triangle strip in front sounds a bit odd on a tar paper roof...

 

[petersson79]

Do you mean a triangular strip on the sides and the highest side, shouldn't it be that way?

Yes, that one works, or you can talk to a tinsmith to make one with the right length on the fold.
Lovely view you have

Yes, it looks great. I was unsure of what you meant by "at the front". I worked as a sheet metal apprentice for a few years, so I've installed some sheet metal. What you need to do is measure the size of the curb all around, including lengths - feel free to take photos too, then you should go to a sheet metal worker and order sheets that fit the ridge. If you're going to have a gutter too, it's good to have a base plate, hooks, cover box, gables, and downspouts with fasteners for wood.

Foot plate is in place, so it's all good. A tinsmith would have been an alternative, but impossible to get hold of. Especially now.

But we'll go with those plates, just cut the upper wind board.

Next problem then - how do you handle the corners where the plates meet? Anyone able to make a simple sketch?

Turned out decent in the end...
