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.
One square covers 100 square feet, so to cover 1900 square feet of roof you would need 19 squares. However, you also need "starter shingles" and "hip and ridge" shingles, plus you need to have a few extras because of waste from cutting angles. Starter shingles go around the perimeter of the roof as a bottom layer for the first course of shingles. Hip and ridge shingles go, as you might expect, on the hips and ridges. In order to know for sure the exact quantity you would need for the entire roofing job you have to measure all of these areas.
1957 sq feet of shingles will cover 1957 sq feet lol? retard much?
How many bundles of 3-Tab Shingles are needed to cover 80 square feet?
Cut three tab shingles for your ridge cap. (20 year)
4 bundles of shingles covers 100sq.ft. of course this is approx. shingles come in several sizes and then you must allow for waste cuts etc
Your roof surface area will be about 785 Square feet. So you need 8 squares of shingles.
16.8 Square, but, you can only purchase full square packages
If you have cut up roof you will need just under 10% for starters and ridge cap. (3 tab) Example a 60 square roof would need 5-6 squares. Lower pitched roofs would of course require less.
It depends on the type of shingle. A traditional "three tab" shingle will cover 21 lin. ft. of ridgecap.
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.
A bundle of Shingles will cover roughly 33 square feet. A square of Shingles (3 Bundles) will cover 100 square feet.
