A 'bundle' is an arbitrary amount - Usually we talk about 'squares' in roofing. One 'square' is 100 square feet
When talking about the area of a roof, remember that it is not the same as the square footage of the structure. For example a 20 x 30' building with a 12" overhang and a 4/12 pitch will have 736 sq ft of roof vs only 600 sq ft of slab. One square of shingles covers 100 square feet. 15 year shingles come 3 bundles to a square. 25 year come 4 bundles to a square.

One squarer of cedar (100 square feet) weights about 90 pounds for the cedar it's self.
The word "square," when used in context with roofing (shingles) and exterior siding, means one-hundred square feet. So, a square of shingles is 100 square feet of shingles. A square of siding is 100 square feet of siding. One hundred square feet is ten feet by ten feet.
You cannot weigh an area. Just as you cannot weigh a distance. (How much does one centimeter weigh?)

measure the square footage first. one square of shingles (3 bundles) covers 100 sqft. divide the square footage by 100 and that's how many squares of shingles you need (be sure to buy enough extra to cap the roof with and compensate for waste at the ends. (starter and ender shingles)
