BEST ROOFING COMPANIES Adventures
The best flat roof roofing material is undoubtedly a single sheet of rubber custom made for weather-proofing flat roofs, such as for example 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 the two, and if you are renewing your flat roof anyway you might as well take the opportunity of renewing that simultaneously.
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 used material for a new 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. With regards to the material used, this could mean heating a good 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 by the end spreading a layer of stone chippings over 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 experts. In addition, there were 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 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 find out exactly where the rain was getting 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 by way of a weakness in the bitumen felt and travel along a rafter before descending to the ceiling board below.
Roof Cleaning in Spalding of rubber-based flat roofing systems are far superior. Should 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 current price is only around �6.65 per square metre.
Most suppliers cut the material to the exact shape and size that you require so there are no unnecessary joins, meaning no weaknesses and an extremely long-lasting, leak-proof roof.
The vital portion 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 you can find no problems it is critical to run the rubber material up and under the tiles or slates of the adjoining pitch roof in order that any rain dripping from the lower-most row falls onto the rubber, with no 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 in such a way 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 top which could obstruct the drainage of the water away.
Rubber roofs have been shown to last for well over 50 years under all weathers, so that it really is the only flat roof roofing material you need to consider when deciding on a fresh flat roof.
