I am building a small side extension and hopefully roofing it soon. I am trying to work out the maximum pitch I can achieve. The side of the house has windows with a brick window ledge underneath. I would like to start the flashing at the mortar line under these windows and follow across.
Building regs indicate 75mm flashing above the tiles. so basically a brick and mortar bed. Is there a rule of thumb for the spacing allowed for batons and concrete tile from the top of the wall plate, rafter joint to the underside of the flashing. I am trying to work out where i should position my wall plate to utilise as much height as possible.
