# Hip Roof Asphalt Shingles

The Hip Roof Asphalt Shingles Calculator is essential for accurately estimating the number of asphalt shingles required for your hip roof project. This calculator considers the unique characteristics of hip roofs, ensuring that you get precise measurements and quantities. By inputting your building dimensions, eave overhang, roof pitch, shingle coverage, and waste percentage, you can quickly determine the total shingles needed, including adjustments for waste and starter strips.

Note:
`One pack of standard shingles = covers 33 sq. ft. a pack. The starter strip and ridge capping results are in lineal feet needed for those two items and are not included in the Total Packs Needed.`

#### Calculator

1. enter the length of the building in feet and inches
2. the width of the building is in feet and inches
3. the eave overhang in inches
4. the roof pitch as a ratio (e.g., 6 for a 6/12 pitch)
5. enter the coverage area of one pack of shingles in square feet
6. a waste percentage to account for cutting and fitting

#### Results

1. the total roof area in square feet
2. the roof angle in decimal degrees based on the pitch provided
3. the length of the ridge in lineal feet (top ridge plus the 4 hips)
4. the length of the starter strip in lineal feet
5. the number of packs of shingles required to cover the roof area
6. additional packs of shingles needed to cover waste during installation
7. the total number of packs of shingles required for the project, combining the roof coverage and waste. Does not include shingles for capping and starter strips

Using this calculator, homeowners, contractors, and DIY enthusiasts can effectively plan their roofing projects, avoiding the pitfalls of over or under-buying materials. The detailed results help ensure you have all the necessary materials to complete your hip roof with precision and efficiency.
