Shed cladding in very tight spot?

[rar4s]

Hi, guys. I have a studwork garden building which has had to be built very close to, but not touching, a higher brick wall. I have clad three exterior sides in shiplap, but the side close to the wall has about a fist of clearance and I can't nail or screw anything from that side. That side of the building is also an irregular shape, i.e. it is not just "square" but steps wider as you go up. Hard to picture, but just know that it's not regular.

The options I can think of are either some kind of hard sheet material (would have to be somewhat weatherproof, but ply would probably last long enough), which I would have to cut into a few pieces and slide in from the side, and screw from the inside. Problems include no way to seal the joins from the outside, and having to screw from the inside.

Or, perhaps some kind of soft/roll material that I could apply, and bring around the edges a few cm to batten on. Again, though, I can't fix that to the studwork from the outside of the wall.

Any ideas or suggestions? I'll get some pictures in daylight tomorrow.

Many thanks,

first question does the roof slope to this end or away and no gutter??
how tall is it and can you slide sheet material in whole

The wall is about 2.8m highest and there's a pent roof - this wall is one of the sloping edges. I'm putting onduline on the roof and though there won't be flashing, I can make the onduline touch the brick wall itself, so there'll never be any direct weather on that wall.

I may be able to get a whole sheet in, come to think of it. Just about - cut to shape (irregular) first.

ok just to clarify there will be water directly shedding on to the brick wall [do you own it]??
or do you mean the brick wall has the apex touching it so flow parallel to the brick wall??

The brick wall runs along the sloping edge of the roof, so the only shedding from the roof will be the tiny fraction running off sideways from the very last ridge of the onduline. Given that previously the entire wall was fully open to the weather, and now ~3m of it are mostly shielded, overall there will be less water on it than before.

The main runoff from the roof will flow parallel with the wall and into a gutter running perpendicular from the wall.

Pics tomorrow, I'm probably not explaining it well!

ahh ok sounds fine
just remember if you dont own the wall you need permission to touch it
further comments
is the room elevated on top off say wooden joists or does it have say a slab as the floor with walls sitting on it??
