This afternoon, we decided that we needed to build a fixed scaffolding framework around the back of the house as our mobile scaffold tower will not be able to navigate down the back as the gap between the house and swimming lane is barely 1200mm wide and the tower itself is 1300mm wide in the first place but also we have tight corners and we won’t be able to move the steel scaffold tower around these corners either. So instead, we are going to build a fixed semi-permanent wooden framework of legs and struts to hold up a sheets of 8feet by 4feet plywood, and join them together to form a walk-way at about seven feet off the ground (about 2 feet below the Fascia level). We would be able to go from the “I” section at the start of the back of the house, along “J”, “K”, “L”, “M”, “N”, and “O”, the other end of the house. We using old CLS timber we have recycled from other jobs and cut them into the various parts to make 30 twin-leg modules to make five 8feet long platforms and three 16feet longer platforms. They will be connected together and also fixed to the building in lots of places to ensure that the whole framework is good and solid for maximum safety.
This scaffolding will probably be there for most of the rest of the year while we work on the roof, getting all the elements done, including the Skylight. we will only take it down when the slate tiles are on and the guttering is all complete and fully working. It might take a few days to build it all but it will save many hours, or even days in not having to keep moving the mobile tower around all the time. We can afford this because we had recycled timber to hand and spare plywood boards but doing it properly using steel equipment would have cost many thousands to hire or buy, as we can only work so quick and we rather spend the money on buying materials like Oak Timber instead.
Tomorrow, we will carry on preparing the old recycled timber, chopping it down into 30 pieces of 900mm lengths and 60 pieces of 2100mm lengths. Also make 60 triangular plywood pieces plus 60 flat “foot” (using more plywood leftover pieces) and then long 16feet (4.8metres) CLS timber, three of them for each long platform module which will have two full size sheets of plywood screwed down. All the platforms will have safety edges on them to provide some protection against walking off the edge or kicking a box or trug of tools over the edge too!

This morning, we sat down and did some analysis on the rain collection quantity for each of our roof sections, which totals (including the proposed Conservatory) to 360 square metres. This includes the Skylight region as well. This means that for every 1mm of rain falling on our house roof, we would be collecting 360 litres of water. So for a 10mm rain shower, there would be 3600 litres of water (3.6 tons of the stuff!) pouring into our pipes and down into the rain soak-away modules (or into our rain storage tank when we have made the filtration unit!!).
The eight down pipe connected to the guttering will handle this quantity of water and our analysis and calculations have assigned which section of roof is combined together for each given Downpipe channel. The other calculation was the angle of the guttering slope or fall. For the longest runs, there will be a 30mm drop from one end to the other (about 10 metres of gettering, making it about 3mm drop for every 1metre or in standardised units, about 1 in 300 angle).
We then went around all the eight downpipe channel positions to measure the offset of each module again against the Fascia’s bottom edge so we know how much to add these “drops” in relations of that edge, at the start of a run.
This now means that we have numbers assigned for all the corners of the roof and the next job is to snap a chalk line at the appropriate height and then cut a slot into the Fascia board, ready to receive the Oak guttering pieces.

We finished off the “P” section of the Fascia boards where they connected to the temporary Downpipe Channels (which are alongside what will be the conservatory). After that bit was done, which saw the final conclusion of getting our Fascia Board up, all 77 metres of it on 15 sections of roof, all aligned up […]

Under some glorious sun, we continued with the mounting up of the Fascia Boards. We resumed on the “H” section, then around an outside corner which had it 45° bit put on, done the “I” towards a downpipe inner corner, together with the neighbouring “J” section. This joined up to the “K” long section (on […]

Yesterday we tackled the job of installing one of our Downpipe Channels for the first time, now that we have up enough Fascia board. The “AB” corner was our designated target. After careful positioning of the channel module, from below and then from above, and double checking gaps between pencil marks etc., we then proceeded […]

Yesterday and today, we carried on processing the Fascia boards, sorting out the pile of Oak pieces, taking off the bad ends, adjusting lengths for outside corners, slicing bevel ends, cutting biscuits joints and sanding down rough patches. We got sorted enough pieces so we could tongue and groove several lengths ready for the “C” […]

Yesterday and today, we continued with the processing of the set of Fascia Boards that has the 32degree slope on them, and sorted them out to form sets for the five sections of roof that are the same angle. These are the “A”, “E” (along the front of the building), “G” (the short sticking out […]
