What to do if your house has good roof, but rotten walls which you need to replace?
Well there is a safe way to support a house roof with special lift's made for construction industry.
I choose "Perri" brand lift's 2.6m Hight. And prefabricated plywood beams.
In total I had 16 pcs. of lift's and 12 beams it was enough to support half of a house roof in weight 4.1 Tone.
I counted every 1.2 m per tower, 4 rows.
Install was hard, with chainsaw I cut holes in the walls, to push through a wall plywood beams for support.
