Now we come to the serious bit: Having laid the relatively straightforward tiles on the plain rear of the roof, it was time to face the really tricky sides!
The problem was ensuring that the courses were all aligned at the hips...
...and centred too:
The only saving grace was that the horizontals would be visually interrupted by another gable, providing a small amount of wriggle room!
After twisting and turning the thing around while desperately trying to find the best way to accurately mark it out, I eventually decided upon this method:
I found that there were some slight anomalies on either side, so simply drawing right across and joining the points led to some tapering lines. Start on that road, and the error rapidly compounds. By clamping a straight strip of scrap on the vertical centre line I was able to check and correct any lines that had slightly drifted. When the procedure was flipped there were a few odd misalignments, but it was then possible to make the very fine adjustments necessary.
All a bit long winded and a right old fuss I know. The trouble is, roofs like this are a mass of geometry, so there is no getting away from it. Losing patience and concentration at any stage will result in a MESS of geometry! Unfortunately, that then tends to stand out and shout loudly from miles away!
Whew, as far as I could see, everything has lined up? The big test will come when the Arris tiles are fitted - much, much later? I don't normally chew my nails - but there was affair amount of gnawing and gnashing going on at this point!
I also finally remembered to add the extra layer of tile strip along the bottom - BEFORE starting the first row... Hah, hah!
Rather awkwardly, the first five courses had to start on this dangly down bit of the roof.
That dear old dollop Mr. Ashbee (and the Directors of the GER!) way back in 190o and something had no idea of the headaches they would cause someone, so many, many years later?!
Don't look too closely, I think I only just about got away with it?
Every few courses, I only applied glue to the ends of a complete strip, let it set, and then cut away the dry middle to make absolutely sure that the verticals remained true. Naturally, I allowed myself to be distracted every now and then, forget what I was doing and habitually apply adhesive all the way along...
...What a wally!
I have left the gap running up toward the ridge, hopefully to minimise the amount of fiddling that will be required with one-and-a-half ("Gable") and trimmed "Ordinary" tiles when the new Arris Hips are finally made and fitted?
There is one good thing about doing all this here at JB's - apart that is from the good company... AND the cakes!..., is that I don't have to keep running up and down ladders or scurry along scaffolding in the wind and rain to reach this lot!
