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.
That 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 are renewing your flat roof anyway you might as well take the opportunity of renewing that at the same time.
This will almost certainly function as recommendation you obtain 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. Based on the material used, this could mean heating a solid bitumen-based compound to create it liquid, and then pouring it onto the underlying felt and spreading it evenly over 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 the sun’s rays and stop 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 were 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 would be very difficult and messy to discover 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 source of it. Roof Cleaning in Stamford could get by way of a weakness in the bitumen felt and travel along a rafter before descending to the ceiling board below.
The brand new generation of rubber-based flat roofing systems are far superior. Assuming you have reasonable DIY abilities then you can 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 current price is around ï¿½6.65 per square metre.
Most suppliers cut the material to the exact size and shape that you require so there are no unnecessary joins, meaning no weaknesses and an exceptionally long-lasting, leak-proof roof.
The vital section of the 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 there are no problems it is vital 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 possibility of 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 simply 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 entire underneath of the rubber to be able to avoid bumps in the surface that could obstruct the drainage of the water away.
Rubber roofs have been proven to last for more than 50 years under all weathers, so it really is the only flat roof roofing material that you need to consider when deciding on a fresh flat roof.
