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

That is laid directly onto roof boarding, itself supported by the roof rafters and nagging. Insulating material is generally laid in the space between your two, and if you are renewing your flat roof anyway you might as well take the opportunity of renewing that at the same time.

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 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 the material used, this may mean heating a solid bitumen-based compound to create it liquid, and pouring it onto the underlying felt and spreading it evenly over the whole section of the roof.

Then you had to hold back for the compound to cool before applying another layer, and at 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 was very easy to fail to make the roof weather-proof, e.g. where in fact the edge of the felt met the existing 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 determine exactly where 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 easily get through a weakness in the bitumen felt and travel along a rafter before descending to the ceiling board below.

The new generation of rubber-based flat roofing systems are far superior. When you have reasonable DIY abilities then you can probably do it yourself, with one other person to aid. You can easily find a local supplier of rubber flat roof roofing material online, and the existing price is only around �6.65 per square metre.

Most suppliers slice the material to the exact shape and size that you require so are there no unnecessary joins, meaning no weaknesses and an exceptionally long-lasting, leak-proof roof.

The vital section of the whole process is to ensure that there are no gaps between the rubber roof and any existing pitch roof where rain may penetrate. To ensure there are no problems it’s important to run the rubber material up and beneath the tiles or slates of the adjoining pitch roof so that any rain dripping from the lower-most row falls onto the rubber, without possibility of it over-lapping the edge and getting within the pitch roof.

Also, make sure that the prevailing slope of the flat roof towards the guttering or other method of water escape is maintained. The rubber is simply 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 Roof cleaning near me 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.

Rubber roofs have been proven to last for well over 50 years under all weathers, so it really is the only flat roof roofing material you need to consider when deciding on a fresh flat roof.
