Laitance on a new slab - how to approach removal/repair?

I'll go with you there Paul. I didn't give any thought to different building codes for different regions. Some of the shed mobs down this way use Trimclad with a .35BMT for the walls (at work we use .42 for just about everything but our sheds are bigger than most, a couple of hundred metres long sometimes). Another bad on my part and I don't know how I didn't see it last night but there IS a screw in the bottom corner of the flashing. In my defense though, in the second pic it looks like the screw was too low to pick up the purlin and if so the roofer would have known that he'd missed the purlin.

You can never have too many nails in a shed.

My walls are the .42, the roof is .35 as the shed order was stuffed up. As a result I have a thin Trimclad roof & thicker corrugated walls.
There's no screw in the bottom corner of the flashing. Here's the other end of the shed with no screw either:

IIRC, .35bmt is classified as " non- trafficable". How did they put the roof on without walking on it ?.

Carefully I assume. One panel was bent by stepping in the wrong spot which they reluctantly replaced, along with the damaged cover panel they fitted when they realised that they didn't order enough roof sheets for the job.

They most likely had plenty of roof sheets But they stupidly put them on the walls instead

They ran out of wall sheets too, I only had 3 1/2 walls for a few weeks.
