flat roof construction and waterproofing

on a roof with a standing wall, its best to have a capping beams or a coping with concrete which can help direct water flow.. a capping with a 50mm edge out side the wall.

for a concrete roof skirting must be done atlease 100mm high.. liquid bitumen is one the best water proofing matrial that is been used.
As below.. many layers of material is best specially for a wooden roof but if its a concrete slab its not that nessary for this must of roofing felt or bitunen layers since concrete it self is water proof.

Even if its a concrete or wood, even though its a flat rood it need atleast 3% slope .. if not as below there are high chances of water leaking.
