When talking about the area of a roof, remember that it is not the same as the square footage of the structure. For example a 20 x 30' building with a 12" overhang and a 4/12 pitch will have 736 sq ft of roof vs only 600 sq ft of slab.
One square of shingles covers 100 square feet. 15 year shingles come 3 bundles to a square. 25 year come 4 bundles to a square.
14ft x 76 ft = 1064 square feet.
Normally 33. But some are 25.
To calculate the square footage of a mobile home, multiply the length by the width. For a 14x76 mobile home, the calculation would be 14 feet multiplied by 76 feet, resulting in 1,064 square feet. This measurement represents the total living area of the mobile home, which typically includes the bedrooms and bathroom.

Shingles vary in dimensions, and sometimes there are specific bundles of shingles made for the sole purpose of ridge coverage. If you are using the house shingles for ridge, take the length of ridge to be covered, divided by the exposure of the shingle to determine the number of ridge pieces needed. Normally you will get three pieces out of one full shingle. Once you determine the number of full shingles, find out how many shingles are in a bundle and purchase the smallest bundle of shingles necessary to complete the job.
5.85 squares + 15% waste = ~6.75 squares of material needed 1/3 square per bundle of shingles 20 - 21 bundles of shingles (buy 21 and return the extra if necessary - it's i'mportant to have shingles from the same pallet/factory for matching purposes.
A square of shingles covers 100 square feet. So, you need 1732/100=17.32 square of shingles. If you can only buy whole number squares of shingles, you will need 18 squares of shingles to cover 1732 square feet.
A bundle of Shingles will cover roughly 33 square feet. A square of Shingles (3 Bundles) will cover 100 square feet.
