Having completed the timber form-work for the porch, fixed it to the steel structure and creating the up-stands for the roof light, the small area of flat roof and canopy gutter could be covered in glass fibre with flashing up to and behind the larch cladding of the cottage. This will provide a nice long-term watertight weather seal for the roof. The insulated warm-deck roof is now ready to receive the glass prior to being clad in Corten Steel https://en.wikipedia.org/wiki/Weathering_steel
