Torching Lime Mortar

Torching is a method of pointing roof tiles from the inside to help prevent tiles or slates slipping and becoming unstable. It's also an alternative to modern roofing membranes for repairing old heritage roofs and on new eco builds. Using a fatty lime mortar with added hairs and fibres gives you a supremely workable mortar that retains breathability and maximises vapour porosity to aid the transfer of moisture so preventing the effects of damp.
