Sorry I havent been here for a while, Job of the month Jan 2016 London
I bring you to day to our project 352 square metres of overlay roofing system In Kenington London SE14, Our client is a property managment company mcs. The works entailed was to give the existing asphalt roof system a new lease of life so we opted for a nord bitumi high performance system which will give them an aditionall 20 years of guarantee. It is common to upgrade the insulation when carrying out this type of roofing system however this was not required on this ocasion
Prior to the installation a coil test was taken to find the make up and condition of what is made up underneath.
The roof had to be primed first to allow good adhesion between the roofs which was then fitted with a perforated layer cut back from the edges. then a secondary layer of Flexpol 3mm sbs underlay, with bullnosed troweling of the joins. then followed with the Nordegum capsheet layer, all these felts are laid with a continous bleed. It is important when laying a flat roof to stagger the bonds of the intermediary layers and also fit the perimetter edges with a seperate upstand aprons as this is part of the system requirements on most flat roofing torch applied systems.
It Is also important that the roof is designed well with adequate falls to drain off and areas were ponding (water stagnating for a period of over 48 hours).
should be adressed prior to aplication
I have been personally laying flat roof systems now for over 28 years and have seen a lot of changes in flat roofing systems over the years all for the better.
