Until recently the most popular material for a fresh flat roof was bituminous felt laid in three layers, the initial layer nailed down and top of the two bonded to the one beneath with mastic bitumen. Depending on material used, this could mean heating a good bitumen-based compound to create it liquid, and pouring it onto the underlying felt and spreading it evenly over the whole area of the roof.

Then you had to hold back 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 natural sunlight and stop 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 have been several stages where it had been 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.

To ensure there are no problems it is critical to run the rubber material up and beneath 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 within the pitch roof.

Also, make sure that the existing 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 that could obstruct the drainage of the water away.
