Any roof and especially steep roofs require the use of a special protections and fall arrest equipment. You may expect to pay a higher price for this type of roof per square of installation. Roofing: The high slopped roof is, perhaps, the most difficult and dangerous roofing surface to work on. Calculated out this gives an angle percentage of 60. of 10 units is: Angle Percentage (6 /10) x 100.
Example: The angle percent of a slope with rise of 6 units and run. High/Steep Roof Pitch/Slope – Roofs in this category have a slope that is greater than 9 inches of rise for every foot of horizontal roof’s run. To find the percentage of a slope, use this slope percent formula: Slope Percent (Amount of Rise / Amount of Run) x 100. They require special equipment such as roofing jacks, and planks in order to be able to perform the roofing installation.
Medium Roof Pitch/Slope – The roof of this type would fall within 6:12 – 9:12 roofing slope range.Roofing: These roofs with intermediate pitch / average slope roofs are considered to be “non walk-able”, as they represent a higher degree of complexity, therefore they are more expensive to install.
Low Roof Pitch/Slope – This type of roof would have at least a 3:12 pitch, which means that a roof rises 3 feet for every 12 feet of its base horizontal length (not greater than5:12).Roofing: This type of roof is considered to be “walk-able“, and easy for performing a roof installation.
