14ft x 76 ft = 1064 square feet.
The number of anchors and strap downs required for a 14x76 mobile home can vary based on local building codes and regulations, but generally, you might need at least 4-6 anchors and corresponding strap downs. It's essential to consult your local building authority or a licensed professional to ensure compliance with specific requirements in your area. Additionally, factors such as wind zone and soil conditions may influence the number needed.
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.
