Unit Intent
Direct answer: Use roofing squares as input, then validate shingle type, layer count, and haul limits before selecting container size.
Square conversion is powerful for roof jobs, but weight variance across material types means risk should be modeled as range.
| Factor | Baseline | Implication |
|---|---|---|
| Input unit | Roofing square | Faster estimate than loose volume guess. |
| Weight behavior | Material and layer sensitive | Range-based output prevents false precision. |
| Operational check | Haul constraints first | Large bin by volume can still fail transport. |
No. Product type and tear-off conditions create range variance.
Shingle density can exceed haul limits before visual capacity is reached.
