Right, a couple of days to catch up on. Camera batteries failed at an important moment yesterday, with me stuck on the roof in fading light, and no time to go and get new ones. Anyway, I managed to get the flat roof felted:
Remember, this is a very temporary arrangement. Now my original plan had been to tuck the felt under the slates, but that proved utterly impossible. The compromise was to nail the felt to the upstand under the slates, and then to push some DPC between the underside of the slates and the top of the first batten on which the slates were sitting. Nightmare job!. It took 2 hours, lying on my side, working in a 2 inch gap, and unable to see what I was doing. In some places the slates were nailed tightly down onto the batten, and needed prising up. It got done in the end, but I was not a happy bunny.
The other problem was that felt is 1 metre wide, and the flat roof is approx 1.2 metres wide. I decided to nail a batten at the edge of the sheet, and dress the felt up onto that before clout-nailing it in place, and then do the same from the other side, lapping over the first piece of felt. I have no idea at all whether this is the right thing to do: I am making this stuff up as I go along! It just seemed like a good idea at the time.
My first job today was to get some gutters up at either end, and lead the discharge water away to somewhere it can't do any harm. However, access to the roof was difficult. I couldn't properly get a ladder to it at either end, so I built one up the utility room roof:
Then screwing a gutter in place was easy........but fixing a downpipe when there is only one of you was a bit of a challenge:
My plan today had been to felt and batten the rear aspect of the main roof, but it was not only windy, it was forecast to turn into gales again by the evening (and they were right......it's howling now). It is difficult enough trying to put sarking on a roof in a breeze if there are two of you, but it is virtually impossible by yourself, so, I was forced into a change of plan.
The inside of the building had turned into a complete tip, and so I spent 2 or 3 hours tidying it up. Separating the timber laths from the render so that the former can be burned and the latter buried took some time. I noticed that the last of the modern render on the brick plinth was about to drop, and I didn't want it to damage my plastic DPM, so I took it off in pieces. This is what happens when you put a hard modern cement render onto old bricks:
Just to confirm, you are looking at the back of removed bits of cement render there, and you can clearly see they have pulled the faces off the bricks, wrecking them. This is what the remnant plinth looks like:
I have a new theory about the soil between the render and the bricks. I reckon it was taken up there by ants and worms, initially through the mortar courses. Another reason why rendering down to the ground is such a stupid, stupid idea.
Anyway, a couple of hours with a shovel and broom, and the place looked a bit better:
Next, to the workshop, and more sprockets, this time for the main roof. These are going to be slightly chunkier, and with a slightly bigger overhang, compared to the utility sprockets.....so, a new template. I drew it in Autocad, printed it full size, and pasted the print onto a piece of scrap MDF:
Then I cut it out on the bandsaw:
....and there you have your template, which just needed a little cleaning up.
Finally, grab some oak, mark around the template, and get cutting:
Just 23 to go......
