How many full bundles of wood shingles are needed for a 28' x 48' building with a hip roof and a 2' overhang, accounting for waste?

To determine how many full bundles of wood shingles are needed for a 28' x 48' building with a hip roof and a 2' overhang, it’s important to first calculate the total roof area, including the overhang and accounting for waste, which typically ranges from 10% to 15%.

1. Calculate the dimensions of the roof:

• The building's footprint is 28' x 48'.

• Including the 2' overhang on each side, the overall dimensions of the roof increase to 32' x 52' (adding 2' on each side).

2. Calculate the roof area:

• The total area of the roof is calculated as 32' x 52' = 1,664 square feet.

3. Determine the area of the hip roof:

• For a hip roof, we must consider that the triangles formed on each end also need to be covered, and the design can lead to some areas being less efficient. The total area can get complex, but in general terms, the calculation of a hip roof usually prompts a need for increased amounts of shingles.

4. Accounting for waste:

• It’s standard
