Easy way to figure it: If the roll is 3 feet by 100 feet, it would cover 300 square feet. But you have to overlap it about 6 inches at top and bottom, so once you subtract that, it would cover about 200 square feet., When figuring a job, add some for overlap at valleys, chimneys, etc. . . Hope this helps. A standard roll of 30# felt covers 216 square feet; one-half the area of a roll of 15# felt, which covers 432 square feet. Rows are overlapped 2 inches, not 6 inches.

1 square = 100 square feet x 8 squares = 800 square feet. 15# felt comes in different sizes. Multiply the length of the roll x the width of the roll to find out how many square feet are in a roll. 800 divided by the square feet per roll = how many rolls you need.

That depends on the size of the Butcher Paper Roll. A 12 inch wide, 900 feet long roll one has a roll weight of 12 lbs. If the roll was 18 inch wide and the same length the roll weight is 18 lbs. A 30 inch wide, 1000 feet long has a roll weight of slightly above 30 lbs.
