Tear-off day runs on rhythm: shingles slide, the can fills, the crew never stops. Here's how the pros set it up.
Squares per can
- 20-yard: ~25–30 squares of architectural shingle (single layer)
- 30-yard: ~40–45 squares — the big-residential and small-commercial standard
- 40-yard: TPO and membrane jobs, where volume beats weight — see our TPO guide
Double layer? Cut those square counts nearly in half or plan a mid-job swap.
Placement that saves labor
Tight to the eave on the tear-off side, boards under the rails on driveways, rear doors facing the debris path. Every foot between the roof edge and the can is a foot your crew carries shingles all day.
Weight, handled
Shingles ride as flat-rate C&D with Muckpro, so a proper single-layer load in the right can doesn't spring overage surprises. Keep household junk out of the shingle can — mixing changes the math.
Swaps without slowdowns
Call when the can hits three-quarters and a fresh one arrives before the last shingle drops. It's why local roofing crews standardize on us — roofing dumpster service is a core route, not a side job.
