London Flat Roofing. 154c Fleet Road, Hampstead, London NW3 2QX
This video shows detailed drawings on how a warm flat roof is constructed. I link to two other videos, one on cold flat roof construction and one that’s an in depth comparison between cold and warm flat roofs, also showing thermal imaging of poorly performing, insulated flat roofs.
Basic tutorial for animation in Sketch Up. I made this video to help me remember the first basic steps. There are some excellent tutorials on how to animate in Sketch Up on YouTube, however everybody assumes we know the basic principle and it took me two days to work out this part. Now I can go forward and advance my modelling.
We show you how we dress Kemper around skylights added to a new roof some years after the original roof was laid. It takes time to dress any flat roofing material around flashings, even Kemper takes time, however one thing we know for sure is that Kemper will stay put, remain flexible and last longer than most outer flat roof coverings.
Part L of the Building Regulations and insulating flat roofs. Part L has always been an issue with flat roofing as some people don’t want to insulate their flat roofs.
This old flat roof above a shop in Pinner was leaking for some time. As it’s a walkway to the flat above, the new roof had to have tiles over the top. This roof was well constructed so we were able to use normal concrete tiles rather than promenade tiles. The roof walls were insulated using Kingspan insulation to a depth of 100mm, then a new decking over the top with the Kemperol V210 System.
The customer’s insurance company made the decision to dress over this new, but leaking, asphalt balcony. The roofing details to the parapet wall and the railings are very poor; the roof was leaking in several places. As the majority of the roof is detail and to dismantle the windows and the railing would be expensive, the decision was to take a two stage approach to stopping the roof from leaking.
This new flat roof has been laid using the Kemperol v210 System. We laid the system over new decking over insulation which forms a warm roof that conforms to the new building regulation standard Part L1b. Promenade tiles have been laid over the new Kemperol flat roof to protect it from people walking on it; the promenade tiles are standard light weight tiles.
Kemper V210 or Kemperol is a liquid roofing material used to form new flat roofs. It’s a system that always stays flexible. Kemperol can be over laid on old felt roofs or on old asphalt roofs and can also be used over ply and concrete.
Here you can start to see the buildup of the complete new flat roof, including the decking and insulation. Thermal bridging through the joists is prevented because of the use of the wood fibre insulation – this bridges across the tops of the joists in a continuous slab.
Flat roof insulation and a liquid applied roof finish, not a liquid rubber but a material called Kemper. Forming a box gutter on a flat roof can be complicated; we now use the Kemperol v210 System. Kemperol v210 stays flexible for the lifespan of the roof. Liquid flat roofing materials are superb for use on flat roofs and box gutters that have lots of detail. If you have ever worked with mineral felt, just think how hard it would be to dress the felt inside this box gutter!
