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 =)
A standard bundle of 3-tab shingles typically contains about 20 to 29 shingles, depending on the manufacturer and the specific product. Each bundle generally covers around 33.3 square feet of roofing area. It's always best to check the packaging or the manufacturer's specifications for exact numbers.
Depends on the type of shingle (asphalt, shake, slate, etc.). Most asphalt shingles weigh about 75lbs/bundle, at 3 bundles per square (100 square feet per square).
100 square feet is called a 'square'. Given that, you roof is 36 'squares'. Shingle coverage for 20, 25, and 30 year shingles is 3 bundles per square. 40 and 50 year shingles are 4 bundles per square. Say the shingle you select has a coverage of 3 bundles per sqaure: the number of bundles you need would be 3 * 36, plus the amount for caps (which cover the 'peaks' and 'hips' in your roof. To estimate the amount of bundles you need for peaks, assume one bundle for every 25 feet of 'hip' or 'peak' you need to cover.
at least 25 bundles With an average of 3 bundles per square(100 square feet) an 8 square roof would need 24 bundles plus 1 for cuts and shorts.
A bundle of shingles weigh ~ 80lbs, so it depends if you are using 3-tab or architectual shingles. There are usually 22 shingles in a bundle of arch. and 26 in a bundle of 3-tab. Doing the division and arch shingle weighs ~3.63 lbs and a 3-tab weighs ~3.08lbs. The weight will very depending on the brand and style of shingle as well... Hope that helps you...
what is the weight of a sq of 3 tab and a sq of arutectural shingles
It would depend on the type of shingle you choose, 15yr., 20yr., 30yr.,40yr. The higher the year wear the heavier the shingle
A standard 3-tab shingle bundle typically contains about 33 square feet of coverage. To calculate the starter needed, you generally require one starter strip for every three bundles of shingles. Thus, you would typically use about 11 feet of starter per bundle, translating to approximately 33 feet of starter for a full bundle of 3-tab shingles.
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.
Shingles are rated in pounds / 100 square feet. Typical ratings are 235# or 265#. 1 bundle of shingles covers 1/3 of 100 sq feet. 235# shingle / 3 = 78.33 lbs
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.
Three bundles per square
36 inches long. Each tab is about 12 inches long.

A standard bundle of shingles typically contains about 21 to 30 shingles, depending on the manufacturer and type of shingle. Each shingle usually measures around 3 feet long and 1 foot wide, but dimensions can vary slightly by brand and style. Therefore, the total length of shingles in a bundle can range from approximately 63 to 90 feet, assuming they are laid out end to end.
A standard bundle of 3-tab shingles typically covers about 33.3 square feet. However, this can vary slightly depending on the manufacturer. It's important to check the specific packaging for precise coverage details.
