How To Calculate Materials for Roofing

How many squares do you need for a new roof. I go over how to calculate how many squares you need of composition roofing for a roof. Some drone footage of the roof getting installed and the mistake I made on my roof. How to find the area of a triangle, rectangle, trapezoid, and parallelogram.

Thank you so much for sharing your knowledge! I really appreciate you. I’m interviewing for a Manager in Training position for a top roofing company tomorrow, and the ad said NO EXPERIENCE NECESSARY. My background is in Customer Service and Logistics, permits, computer stuff. Never once worked on a house aside from building pools, so I’m trying my best to prepare for this interview so I can be ahead of the game.

Wait, so the square with the line in the middle is notation for squares, or is it notation for square feet?

[moneygrowz]

isn't the height 15? for the trapizoid?

This is missing slope correction. Plus, there is additional waste that the sum needs to be multiplied by (not advocating for bundled waste %).

i use an engineer's wheel on the ground, , i draw the roof giving the measurement for each side then use pitch factor, , if i have a 4 hip roof (rectangular shape )and across the front its 40 ft by 20 ft down the side will equal 800 sq ft ..If the pitch is a 5/12 ( pitch factor is 1.083), , so 800 x 1.083 = 866, , , being a hip roof (15%) for waste 866 x .15% = 129.. so..866 +129 =995 SQ FT ..I WOULD ROUND UP TO 10 SQ FOR THE ROOF, , That includes starter and hip and ridge cap ..
