I am about to permanently cover my roof terrace, which will remove access to another small existing roof (I can currently get up there via step ladder from uncovered terrace).
My neighbour's, single pitch, tiled roof abuts the terrace, and is accessible (from the side of the terrace) and easily strong enough for careful access by an adult. Once on this adjoining roof I would be able to climb up for maintenance access to the small roof mentioned.
But...I need to fix some steps into said wall to do this.
Shouldn't be permanent as I can't risk the kids heading up there when they're older.
The best ideas I had so far:
1. knock out, and cement in steel guide tubes, for slotting in thick-gauge steel re-bar, bent into 'n' shapes.
2. same, but bigger holes / sleeves, and using thick wood, inserted to almost depth of wall.
