CertainteedQuiz WHAT ARE YOU LEAVING ON THE ROOF WHEN THE JOB IS DONE? How solid is your labor acumen? Take a minute (literally) to test your knowledge. Do you document your crews' labor time by task and product?YesNo Have you observed how effectively your crews communicate?YesNo Do you regularly maintain equipment?YesNo Do you employ a rooftop manager and quality control program?YesNo Do you accurately account for non-productive elements of the work day?YesNo CAN YOU GUESS WHAT WE LEARNED? These last five questions pertain to labor efficiency facts and figures we observed…. 10’ wide, 60 mil TPO: How much more time did it take to fully adhered vs. mechanically attach?47% more time26% more time How much time do you think a multi-torch wagon can shave off a hand-held torch-applied bituminous cap sheet (installer minutes/square)?4.75 man minutes per square (9% less time)8.25 man minutes per square (17% less time) Which of these coverings averaged 52.5 installer minutes/square in the field?10’ wide, 60 mil PVC (fully adhered)Bituminous self-adhered base with self-adhered cap10’ wide, 60 mil TPO (mechanically attached)Bituminous mechanically-attached base with torch-applied cap (multi-torch wagon) Which low-slope roof covering, on average, was the the fastest to install? (assuming a 500 square project with 900 lf of base flashing, 22 pipe, 6 drains and 10 equipment curbs)Bituminous mechanically-attached base with self-adhered capBituminous hot-asphalt-mopped base with hot-asphalt-mopped capBituminous mechanically-attached base with torch-applied cap (multi-torch wagon)10’ wide, 80 mil TPO (mechanically attached)10’ wide, 60 mil TPO (mechanically attached) Which low-slope roof coverings, on average, was the most cost-effective to install? (assuming observed labor efficiencies on sample project identified in question (4) and national average material prices from 20 distributors in 9 regions of the country)Bituminous mechanically-attached base with self-adhered capBituminous hot-asphalt-mopped base with hot-asphalt-mopped capBituminous mechanically-attached base with torch-applied cap (multi-torch wagon)10’ wide, 60 mil PVC (mechanically attached)10’ wide, 60 mil TPO (mechanically attached) Fill out this form to get the full report "Factors Impacting Low-Slope Roofing Costs - A National Labor Study" Full Name Email Time is Up!
