We currently have some roofers covering up an old skylight and fitting a new one. Before the job started it was agreed they would do the roofing works and we would get someone else to "make good". They are finishing up the job today and have said once the skylight is in they will leave the 3 beams running across the skylight opening in place and whoever comes to make good needs to remove them and plasterboard it all up. I understand the plasterboarding up but surely they should be removing those beams?
