As I without Pete for the day, my plans were to get the roof finished if the weather was fine. Thankfully Ian offered his services for the day. So after a lazy start of 9am (we needed to allow the dew to dry off the roof) we started with finally fixing the ridge capping together. This involved using rivets to join the adjacent caps and plenty of hex screws. The biggest issue we faced was how to install the foam infill strips under the capping to stop the wind blowing any water into the roof. This is particularly important as the roof only has a pitch of 10 and 13 degrees. Because of the 20mm flange at the edge of the capping the foam cannot be completely under the capping as there is no pressure to keep it in place. Instead it has to sit under the edge of the capping so it can be compressed and held. Originally I didn't think to would look very good with a black infill partially exposed on a cream roof, but it actually makes it look completed.
The odd thing is that they make infills for capping that is perpendicular to the roof ribs but no infills are available for capping that is on the angle and the existing infill doesn't really stretch very well to allow a different period in the corrugations. My options were a tar based product that is apparently very messy or a foam expander that I thought might do the trick. The expander seems to work but it also is pretty messy and quite expensive for how much it does. I used one can doing only 1 & 1/2 edges of a single ridge cap. As I only bought 2 cans I won't get the job completed today.
When 4pm rolled around, we called it quits with two ridge caps still missing and a third still requiring the infill to be installed. I think I might need some more screws too.
Many thanks to Ian for his help today. Hopefully I can repay the favor soon.
Clay popped in a convinced me into going to watch the Rats play. Not a bad game but the Rats came off second best.
Black belt grading tomorrow :)
