7 Must-haves Before Embarking On Roofing Roof
The best flat roof roofing material is without a doubt a single sheet of rubber tailor made for weather-proofing flat roofs, such as for example Firestone’s EPDM product.
This 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 chance 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.
Baton Rouge Roofing Until recently the most popular material for a new flat roof was bituminous felt laid in three layers, the first layer nailed down and top of the two bonded to the main one beneath with mastic bitumen. With regards to the material used, this may 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 section 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 the sun’s rays and prevent 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 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 could be very difficult and messy to learn 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 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 look for a local supplier of rubber flat roof roofing material online, and the existing 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 the main whole process is to ensure that there are no gaps between the rubber roof and any existing pitch roof where rain could possibly penetrate. To ensure you can find no problems it is vital 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, 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 means 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 entire 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 fresh flat roof.
