The best flat roof roofing material is undoubtedly an individual sheet of rubber tailor made for weather-proofing flat roofs, such as Firestone’s EPDM product.

Roof Cleaning in Nottingham is laid directly onto roof boarding, itself supported by the roof rafters and nagging. Insulating material is normally laid in the space between your two, and if you’re renewing your flat roof anyway you may as well take the chance of renewing that simultaneously.

This will almost certainly be the recommendation you obtain from any reputable builder or roofer advising you on replacing your existing flat roof.

Until recently the most used material for a fresh flat roof was bituminous felt laid in three layers, the initial layer nailed down and the upper two bonded to the main one beneath with mastic bitumen. Depending on the material used, this could 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 on the roof and bonding it with a chipping compound, this being to reflect natural sunlight preventing 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 was very easy to neglect 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.

On top of that, if, or rather when, there developed a leak in the flat roof, it will be very difficult and messy to learn wherever the rain was getting back in. Seldom would the manifestation of the leak on the ceiling of the room below be directly below the source of it. Water could get by way of 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. In case you have reasonable DIY abilities then you can certainly probably do-it-yourself, with one other person to aid. You can easily look for a local supplier of rubber flat roof roofing material online, and the existing price is 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 the main whole process is to make sure that there are no gaps between your rubber roof and any existing pitch roof where rain may penetrate. To ensure you can find 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 chance for it over-lapping the edge and getting underneath the pitch roof.

Also, make sure that the existing slope of the flat roof towards the guttering or other method of water escape is maintained. 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 to be able to avoid bumps in the surface which 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 that you should consider when deciding on a new flat roof.
