Hi crowbar1954,


Thank you for your question and welcome to our community.


Since you already know he square footage of your area 56 ft X 12 ft which equals 672 sq ft, now multiply that by 1.1.  This is your “OPPS” factor so you can account for any extra shingles you may need. 


Next, you will want to figure out how many bundles of shingles you are going to need.  To do that you will next need to divide the roofs square footage by 100.  This is the number of “squares” of roof you will be shingling.  One hundred square feet equals one “square” of shingles.


Using your measurements as an example:   56 feet X 12 feet equals 672 square feet, times 1.1 equals  739.2 divided by 100 equals  7.392 or 7.4 if you round up.  This number is the number of squares of shingles you will need. 


Now multiplied that number by 3, which is the number of bundles of shingles you will need to cover your roof.  22.176 bundles of shingles will be needed to do your roof, or 22.2 bundles of shingles.  Do not forget the roofing paper!


Have fun with your project!   Please let us know if you have any further questions.
