The best flat roof roofing material is without a doubt a single sheet of rubber custom made for weather-proofing flat roofs, such as Firestone’s EPDM product.

Insulating material is normally laid in the space between the two, and if you’re renewing your flat roof anyway you may as well take the opportunity of renewing that simultaneously.
This will almost certainly be the recommendation you receive from any reputable builder or roofer advising you on replacing your existing flat roof.
Until recently the most famous material for a new flat roof was bituminous felt laid in three layers, the first layer nailed down and the upper two bonded to the one beneath with mastic bitumen. Based on the material used, this may mean heating a solid bitumen-based compound to make it liquid, and pouring it onto the underlying felt and spreading it evenly on the whole section of the roof.
Then you had to wait for the compound to cool before applying another layer, and by the end spreading a layer of stone chippings over the roof and bonding it with a chipping compound, this being to reflect the sun’s rays and prevent the felt and bitumen degrading quickly.
This was altogether a fairly messy, complicated and time-consuming job best left to the experts. In addition, there were several stages where it had been very easy to fail to make the roof weather-proof, e.g. where in fact the edge of the felt met the prevailing tile or slate roofing of the pitch roof.
In addition, if, or rather when, there developed a leak in the flat roof, it might be very difficult and messy to learn exactly where the rain was getting in. Seldom would the manifestation of the leak on the ceiling of the room below be directly below the foundation of it.

To ensure you can find no problems it is critical to run the rubber material up and under the tiles or slates of the adjoining pitch roof in order that any rain dripping from the lower-most row falls onto the rubber, without chance for it over-lapping the edge and getting underneath the pitch roof.
Also, make sure that the prevailing slope of the flat roof towards the guttering or other means of water escape is maintained. The rubber is merely glued onto the roof boards and sealed where appropriate with metal brackets or bitumen in such a way that rain penetration is impossible. Mind that the glue covers the whole of the underneath of the rubber in order to avoid bumps in the top which could obstruct the drainage of the water away.
