It’s been a while since I last posted, and I apologize – life has been busy and it take time to make a blog that is worth reading (and worth writing, for that matter!!).
We are now in the Roofs module and having finished our rafter project, we have learnt about common rafters, hip and valley rafters and jack rafters and how to calculate their length and also how to cut them and place them. The critical measurement to know is the common run – from the ridge to the bird’s mouth and from the hip to the fascia. This combined with the two SGF’s will pretty much give us the line lengths of the rafters.
Now we are about to move on the the construction of trusses and then roofs with complications. The biggest complication is the dormer. Here are a few photos from downtown Ormstown:
As you can see the dormer roofs primarily serve a decorative function – they are centred over the windows and they break the roof line visually. They also shed the water away from the line of sight from the point of view of the person looking out. The one on the left may have originally served to keep the water from the door – before the entrance was constructed.
Here is a close up that provides some talking points:
I am thinking water here.
