I haven’t done much work on the house lately, due to all the snow (and me leaving town again…). But the other night, after working on a cob garden wall with my friend Greg, we were inspired to gather some cardboard, tape, and scissors, and settle in for an exciting night of model making.
I’ve been having trouble figuring out the roof for our house. The roof line. The materials. The pitch. The whole roof design in general. I’ve done sketch after sketch on graph paper, and ended up no closer to any roofing inspiration. After making this model, I realized designing a roof in 2-D just doesn’t make much sense.
Deciding on the materials for the roof has been difficult, partly b/c we are interested in doing rainwater catchment. When collecting rainwater people generally use metal roofing, but metal just doesn’t seem fitting for an earthen building. I was into the idea of making wood shingles/shakes, but that would require a steeper pitch than I want for a house already so tall and skinny, and there is also the whole issue of tannins when collecting rainwater. Thatch, in my opinion, is the most beautiful roofing material, and I definitely plan on experimenting with it for other buildings on our land, but thatch, too, needs a steeper pitch (thatch generally needs a 45-60 degree pitch). Originally I was against the idea of a living roof, b/c I selfishly didn’t want those plants up there using my rainwater, but I’m leaning that way now. We are playing around with different green roof designs that would still allow for some amount of rainwater collection.
And, because I’m a nerd:
