Trim Calculation Formula

Total Trim = (Roof Perimeter × (1 + Waste Factor / 100))

Total Cost = (Trim Length × Material Cost) + (Trim Length × Labor Cost)

The total trim length is calculated based on your roof perimeter with added waste factor. Material and labor costs are then applied. Actual costs may vary based on local pricing, roof complexity, and installer rates.
