Cost guides
The long-form research behind the numbers — what things cost, why they vary, and where contractors hide the difference.
Why our numbers are different
Most roofing "calculators" are lead-generation forms with a number attached. You enter your details, get a vague range, and then your phone rings for a week.
We built the opposite. Every figure traces to a source you can check — BLS wage data for labor, tracked supplier pricing for materials, and real geometry for your roof area. When we don't know something, we say so instead of inventing it.
Read our methodology →Real state labor rates
BLS wage data for all 50 states — not one national average that fits nobody.
Transparent maths
Every formula is published. Pitch multipliers are true secants, not fudge factors.
No lead selling
We never pass your details to a contractor. Nobody will call you.
Sourced, not invented
Where we lack data, we say so — rather than filling the gap with a guess.
