The woodshed roof is finished!














Well, almost... There are a lot more rivets to go in to make it really secure, and we need to add a gutter at the back, but it's on and we managed to do it before the rainy season starts.

We learned there is a lot of Math involved in putting on a new roof. For example, we needed to know the difference between a rectangle (the roof that we thought we were putting on) and a parallelogram (the actual structure of the existing wood shed). We also needed to know how to add and subtract fractions. For example (if you have Math phobia you may not want to read further) what is 25 feet, 5 and 3/8 inches minus 22 feet, 7 and 3/4 inches? And we needed to understand proportions, as in "If we lose 1/2 an inch of overhang over three metal panels (because the shed was not square), how many inches will we lose over nine panels?" All I can say is it's a good thing we were both Math teachers...
