Either 25 sq ft if is is a 4 bundle per square shingle or 33.3 sq ft if it is 3 bundle per square shingle. A square is equal to 100 sq ft.
33 sqare feet
26 shingles in a bundle of three tab asphalt shingles
3 bundles of shingles = 100 square feet 1 bundle of shingles = 33 1/3 square feet
A bundle of Shingles will cover roughly 33 square feet. A square of Shingles (3 Bundles) will cover 100 square feet.
Depending on which manufacturer of starter shingles you prefer, you will get 100 linear feet, give or take a couple of feet for some brands. If using 3-tab shingles as a starter shingle, you will get roughly 78 linear feet per bundle.
9 bundles assuming std. 3 bundle/sq. shingles
each bundle does 33.3 sq ft.
30 by 40 = 1200 sq.ft. divide by 10 = 12 square 3tab and arch shingles are 3 bundle per square 12 sq. x 3 bundles = 36 bundles 3tab = 26 shingle per bundle arch = 22 shingle per bundle 36 bundle x 26 = 936 3tab shingles 36 bundle x 22 = 792 arch shingles =)
if you're using 3-tad shingles for your caps, it's generally 30-32 feet. That's based on 5 3/4" cap exposure with 21 shingles to a bundle. Some companies have smaller shingles, but more in a bundle. Owens corning have 27 with 5" exposure, giving you more length but less width.
Normally 33. But some are 25.
AnswerI'm looking for the exact answer, but I believe it's 26. There are usually 3 bundles in a square (100 square feet) so this would work out right. Of course it would also depend on what kind of shingle it is.-------------------------Actually it is 22
Roughly 33 square feet. Three bundles make a square ( 100 sq. ft. )
2/3 of a bundle of shingles which has approx. 22-23 shingles
