Apply These 5 Secret Techniques To Improve BEST ROOFING COMPANIES
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 Roof Cleaning in Lincoln is generally laid in the space between your two, and if you are renewing your flat roof anyway you may as well take the chance of renewing that at the same time.
This will almost certainly function as recommendation you receive from any reputable builder or roofer advising you on replacing your existing flat roof.
Until recently the most popular 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. Depending on material used, this may mean heating a solid bitumen-based compound to create it liquid, and 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 preventing 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 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.
On top of that, if, or rather when, there developed a leak in the flat roof, it will be very difficult and messy to discover 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 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 vital part of the whole process is to make sure 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 vital 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, with no chance for it over-lapping the edge and getting within the pitch roof.
Also, make sure that the prevailing 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 in order to avoid bumps in the surface which could obstruct the drainage of the water away.
