Tough question because an 1800 sq' home has more than 1800 sq' of roof coverage, unless it has a flat roof. In which case, shingles would not be the material of choice. You need to measure the foor deck itself; either by measuring the gutter and rake (gable) edges to find square footage or, figure the pitch of your roof and calculate from there. You also have to factor in any other roof linrs such as hip roofs, shed or gable dormers, etc.. But if your roof was, in fact 1800 sq' you could figure the bundles by knowing that 3 bundles typically cover 100 sq' sooo...100/1800=18; 18x3=54

3 bundles of shingles = 100 square feet 1 bundle of shingles = 33 1/3 square feet
