   This is great. For one thing, you can zoom in on the roof and use the polygon measuring tool to plot the perimeter of the roof and get a usefully accurate total square footage (for "flat" roofs; sloped roofs are a little more involved, see here for help figuring out the area of a sloped roof). Zoom in on the roof, then select "Tools" at the top left, then select "Ruler". It's pretty self-explanatory after that. If the angle changes too much when you zoom in, go to View at the top left, then click on Reset at the bottom of the drop-down menu, then click Tilt.
