The best flat roof roofing material is undoubtedly an individual sheet of rubber tailor made for weather-proofing flat roofs, such as for example Firestone’s EPDM product.
This is laid directly onto roof boarding, itself supported by the roof rafters and nagging. 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 chance of renewing that at the same time.
This will almost certainly function as recommendation you receive from any reputable builder or roofer advising you on replacing your existing flat roof.
Until recently the most popular material for a fresh flat roof was bituminous felt laid in three layers, the first layer nailed down and top of the two bonded to the one beneath with mastic bitumen. With respect to the material used, this may mean heating a solid bitumen-based compound to make it liquid, and then pouring it onto the underlying felt and spreading it evenly over the whole area of the roof.
Then you had to wait for the compound to cool before applying another layer, and at the end spreading a layer of stone chippings on the roof and bonding it with a chipping compound, this being to reflect the sun’s rays preventing the felt and bitumen degrading quickly.
This was altogether a rather messy, complicated and time-consuming job best left to the professionals. In addition, there have been several stages where it was very easy to neglect 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.
On top of that, if, or rather when, there developed a leak in the flat roof, it would be very difficult and messy to discover wherever the rain was getting back in. Seldom would the manifestation of the leak on the ceiling of the area below be directly below the source of it. Water could get through a weakness in the bitumen felt and travel along a rafter before descending to the ceiling board below.

To ensure you can find no problems it’s important to run the rubber material up and under the tiles or slates of the adjoining pitch roof so 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.

The rubber is merely glued onto the roof boards and sealed where appropriate with metal brackets or bitumen so that rain penetration is impossible. Mind that the glue covers the whole of the underneath of the rubber so as to avoid bumps in the surface that could obstruct the drainage of the water away.
