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 1 out of 11 Have you observed how effectively your crews communicate?YesNo 2 out of 11 Do you regularly maintain equipment?YesNo 3 out of 11 Do you employ a rooftop manager and quality control program?YesNo 4 out of 11 Do you accurately account for non-productive elements of the work day?YesNo 5 out of 11 CAN YOU GUESS WHAT WE LEARNED? These last five questions pertain to labor efficiency facts and figures we observed…. 6 out of 11 10’ wide, 60 mil TPO: How much more time did it take to fully adhered vs. mechanically attach?47% more time26% more time 7 out of 11 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) 8 out of 11 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) 9 out of 11 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) 10 out of 11 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 cap Bituminous mechanically-attached base with torch-applied cap (multi-torch wagon)10’ wide, 60 mil PVC (mechanically attached)10’ wide, 60 mil TPO (mechanically attached) 11 out of 11 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!
