you will have to give measurements for your roof if you want the answer
73 bundles
It depends on the size of the shingle!
Hi, do you mean how many bundles of shingles would be required for a 40 x 20 roof?
8 bundles
Depends on type of roof. On average will require 4 bundles of Shingles.
You will need to get 10 square of shingles, 3 bundles usually equal one square but it depends on if you get 30 year 40 year 50 years shingles ect. talk to your seller, but you will need ten square
One square = 100 sq ft of roof area.
13 square. 1 square of shingles is 100sq feet.
measure the square footage first. one square of shingles (3 bundles) covers 100 sqft. divide the square footage by 100 and that's how many squares of shingles you need (be sure to buy enough extra to cap the roof with and compensate for waste at the ends. (starter and ender shingles)
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.
about 3 squares or 9 bundes plus one for cuts
34 x 24 assuming no overlap.
