Which of these figures fit a slate-to-asphalt job?
The asphalt rows fit, plus slate removal. A slate-to-asphalt job is an asphalt roof with a heavier tear-off and more deck work, so RoofVista's architectural shingle range and Angi's old-roof removal range are the closest published guides. The slate-roof rows describe a different job: putting new slate back on.
