After getting the two big surfaces of the roof shingled, the weather became more persistently winter-like in spite of the local reputation for being the “banana belt” of Ontario. I worked at getting the plywood skirt on the heels of the trusses. This has two functions, 1) to provide additional secure attachment (hurricane ties) of the trusses to the nailing plate which is bolted into the reinforced concrete bond beam at the top of the wall and 2) to reduce the wind infiltration over the top of the wall. In the long term, a space must remain for air circulation in the attic up to the ridge vent on the peak of the roof, but I had enough scrap plywood from the roof deck process that I put temporary closures of the space between the top chords of the trusses held in place with a single short deck screw.
In January I discovered that there was some cracking of the concrete slab floors in both garage and house. On the advice of my cement contractor I guessed it was due to freezing under the slab stressing the concrete by lifting on it. It was recommended that I use heaters to keep the floor from freezing deep, to prevent more cracking and I had purchased a multi-fuel (kerosene/diesel fuel) space heater from my neighbor Ron, down the street who is finishing a strawbale house, and was loaned another by my plumbing electrical contractor. Now whenever the temperature went substantially below freezing I run the heaters to keep the floor temp above zero. When we had our really cold spell, I had not finished closing in the top of the wall so the wind whistled through, and I added a second layer of poly film on my windows. That also helps to keep the interior warmer, even without insulation or real heating. The cement guys assessment is that the cracks will largely disappear when I stain and polish the floors.
I continue plugging along at the interior framing, now working on the walls in the main house.
On the weekend of March 7-8, the weather began to get very Springlike, and I began to prepare for roof work again. On Monday got to it seriously finishing the prep work screwing partial shingles to top the roof to where the roof vents were to be attached. Then finished the second layer of flashing on the solar chimney and installed the ridge vents on either side of it. Then went on to finish the final shingles of the west face of the house roof and installed the flashing at the junction to the wall of the gable.
The weather continued spectacular all week with temps 15-18C, and I went on to install the valley flashings on the breezeway and installing the shingles on the east face of the house roof. If the weather holds, will be able to finish all the steel shingles in a few more days.
Friday, March 19 was the end of the early Spring record high temps through the region. I completed the east face of the garage/workshop roof and called it a day. Saturday it was back down to near freezing with a brisk northerly breeze. Tried to get on the roof and continue, but I had gotten soft with a week of balmy weather and decided it wasn’t worth the pain. Supposed to be back to similar temps next week, so maybe finish the breezeway roof then.
