While I was doing this on Saturday,
Mom was on the roof of our house. She sealed the skylights and made sure the vents were sealed up too. She cleared the leaves out of the gutters and added some silicone to keep the gutter stuck to the house. She is hoping to prevent this:
The giant icicles hanging from the gutter outside. It would help if the winter isn't as cold and we don't get as much snow.
We are hoping.
