Each week the project gets tested by the elements. Last week was heavy wind and this week was heavy rain. We’ve been covering the loose materials and floor with a large tarp in-between work days. The shed appears to have survived the heavy rain and now its time to get that roof up!
Due to the very low slope of the roof I decided to run the rafters 16 inches on center. I think typically you can get away with wider spread rafters but I was a little concerned with heavy snow sagging the roof in the winter.
We started the day early and built our overhanging rafters that will set the side of the roof out about 8–10 inches on either side. They are essentially a thick ladder. Once we had both overhangs built we had to hoist them up and toe nail them to the edge of the top plates. We also gave them some extra support by screwing a 2x4 as a brace that spanned from the rear wall to the rafter that was screwed into the top plate. You’ll see what I mean in the photos if you look at where the outside rafters meet the rear wall.
Once we had both of the “ladders” up we cranked out the rest of the rafters in pretty short time. We also decided to connect the “ladders” to the closest interior rafter as further support to the overhang. The rafters were connected to the top plates with metal brackets.
More rain is in the forecast so we had to get the plywood on the rafters the same day to get it covered. The process went pretty well. We would offset each sheet and trim the excess off with the circular saw. We left an inch overhang of plywood to allow for a facia board that will run around the ends rafters and cover them up.
In the very end we started to run short on 4x8 sheets and had to use scraps to fill the last 4 feet of roof. We ran out of daylight in the end before we could get the felt paper up for water proofing. We tied the tarp to the roof to keep it pretty tight for the week of rain ahead.
