EPDM membrane to a tiled roof transition – how do you connect a flat roof to a tiled roof? 
  • When installing an EPDM membrane system with a tie-in to an existing tiled roof, remove a few courses of tiles.
  • Next, bond the membrane onto the sloped roof deck.
  • Peel the top of the EPDM membrane back and apply a bead of Water Cut-Off Mastic between the membrane and the deck.
  • Nail the top of the membrane every 15.24cms and install the tiles over the EPDM.
  • Keep the bottom course of tiles to a minimum of 10.16cm above the roof angle change. To fasten the bottom course of loose tiles tabs to the membrane, lift each tab and apply a 2.54cm long bead of Lap Caulk.
