Best material to Waterproof a Flat Roof
……………………………………………..
To ensure you get the most out of your new flat roof, an effective waterproofing system must be in place. This will protect the long-term integrity of the structure. Too much exposure to the outside elements will lead to rot and decay of the decking and insulation, significantly reducing the lifespan of the roof. This can lead to costly repairs, or worse, the need for an entirely new roof.
REINFORCED BITUMEN MEMBRANES (RMB) are the most commonly used material to waterproof flat roofs on residential properties. The process involves laying down two or three layers of the material across the full surface of the roof. These are then bonded together by hot bitumen.
1- POUR AND ROLL: As the layer of RBM is unrolled across the roof, hot bitumen is poured out in front to seal the two together.
2.TORCHING: A specific type of RBM is heated using a gas torch without the need to use bitumen as adhesive.
3.COLD APPLICATION: A cold adhesive is spread out across the surface of the roof before the RBM is slowly unrolled, making sure the laps are also sealed using the same bonding material.
Other Materials to use are;
OPTION #1: PVC membrane
OPTION #2: EPDM rubber
OPTION #3: TPO membrane
OPTION #4: Modified bitumen
OPTION #5: Built-up roof (BUR)
OPTION #6: Silicon spray
