Our loft conversion is at the planning stage, architect has submitted the planning application, structural engineers are doing the calculations for building control.
I will be doing most of the work myself and employing tradesmen as required.
The architect has specified deeper rafters spiked to the existing 50mm rafters to go from wall plate to a new steel ridge beam without any purlins and to be fitted without removing the existing slate roof.
I am looking for ideas how this can be done, is it a case of propping up the 3 purlins from ground level, bracing the existing rafters and removing sections of the purlins to fit one new rafter at a time, move the props along as I go, fitting the new rafters ?
Or are there other ways to get the deeper rafters past the purlins that doesn’t involve stripping the roof ?
I will of course be speaking to the architect and structural engineers again, and will probably employ a roofer and joiner to do this part of the job but I want to know how this is done and if anyone else on the forum has done it without stripping off the roof.
