12 Questions Answered About BEST ROOFING COMPANIES
The best flat roof roofing material is without a doubt an individual sheet of rubber tailor made for weather-proofing flat roofs, such as 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’re renewing your flat roof anyway you might as well take the opportunity of renewing that simultaneously.
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 Roof cleaning near me for a new flat roof was bituminous felt laid in three layers, the initial layer nailed down and the upper two bonded to the one beneath with mastic bitumen. Based on the material used, this could mean heating a good 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 the sun’s rays preventing the felt and bitumen degrading quickly.
This was altogether a fairly messy, complicated and time-consuming job best left to the professionals. 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 prevailing 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 might be very difficult and messy to determine 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 foundation 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. For those who have reasonable DIY abilities then you can certainly 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 around ï¿½6.65 per square metre.
Most suppliers slice 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 make sure that there are no gaps between the rubber roof and any existing pitch roof where rain could possibly 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 in order 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 means of water escape is maintained. The rubber is merely 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 so as to avoid bumps in the surface 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 it really is the only flat roof roofing material you need to consider when deciding on a new flat roof.
