Chimney Flashing Calculator
Calculate how much chimney flashing you need for your roof with our comprehensive calculator. Determine materials, costs, and labor estimates based on your project specifications.
Step 1: Project Measurements
Understanding Flashing Measurements
Flashing is typically measured in linear feet. Measure each side of your chimney where it meets the roof. Complex roofs with multiple angles may require more material and higher waste factor.
Step 2: Material & Cost
About Flashing Installation
Labor costs vary by material type and roof complexity. Copper flashing requires more skill to install but offers superior longevity. Steep roofs or complex chimney designs increase installation time and cost.

Cost Breakdown
Flashing Calculation Formula
Total Cost = (Flashing Length × (1 + Waste Factor) × Material Price) + (Base Length × Labor Cost)
To calculate total project cost: Multiply base length by waste factor, multiply by material cost per linear ft, then add labor cost based on base length.
