Joining rubber roofing to felt roof

Could someone explain how the rubber type roofing copes with the heat from sun and also can you safely join it to a felt roof which doesn't need replacing

PVC membranes make up for 80% of the uk market alone and are completely uv resistant a separation layer for mechanically fixed overlay solution or just some new ply over the old felt for fully bonded overlay hope this helps

The epdm rubber is glued to the new osb boards with a water based adhesive and then brushed down to eliminate any bubbles and give it a firm bonding this allowing it to move with the wooden sub structure any joining to a mineral felt roof is done with a termination bar and water block seal compressing the two components together around the perimeter the epdm should be contact glued hope this information helps many thanks SRM roofing &roofline

We always overlap the existing felt Material with the Epdm approx 150 with a 50mmx50mm timber to create a bridge barrier then use a Firestone water block sealant under the rubber on to the felt and bolt a joining bar across the sealant line
