Such repairs can consist in replacing a whole roof element (metal sheet, corrugated board, slate, shingle shingles) or local elimination of a leak without installing new fragments.

Repair instructions: Support the rafter with temporary struts (at the end of the work, they are dismantled). Cut off the rotten part of the element. To make a prosthesis from a metal bar by welding - its length should be 2-2.5 times longer than the cut part. Put the prosthesis on the rafter and install it on the Mauerlat.

The required rigidity of the compressed upper chord of the prosthesis is provided by the brace lattice.
