FreeRoofingCalc Editorial Team
Every guide, cost table, and calculator formula on FreeRoofingCalc.com is researched, written, and fact-checked by our editorial team — a group of residential roofing professionals with combined experience spanning over 40 years in the US roofing industry.
Our team includes licensed roofing contractors, construction estimators, and building science professionals who have personally installed, inspected, or estimated thousands of roofs across multiple US states.
Our Editorial Standards
Field-verified pricing
Cost data is sourced from actual contractor bids, material distributor price lists (RS Means, HomeAdvisor), and manufacturer MSRP sheets. We cross-reference multiple sources before publishing any price range.
Mathematically validated formulas
Every calculation in our tool uses standard construction math — pitch multipliers derived from trigonometry (√(1 + (rise/12)²)), industry-standard 3 bundles per square, and per-square cost tables verified against real project invoices.
Regular updates
Material prices fluctuate with supply chains. We review and update cost data quarterly, and flag "last updated" dates on all pricing guides so readers know the data is current.
No pay-for-play
We don't accept payment from roofing manufacturers or contractors to recommend their products. Our material comparisons are objective and based solely on cost, lifespan, and performance data.
Team Background
Our contributors have hands-on experience with:
- Residential re-roofing (asphalt shingle tear-off and replacement)
- Standing seam and corrugated metal roof installation
- Clay and concrete tile roofing systems
- Flat/low-slope commercial roofing (TPO, EPDM, built-up)
- Storm damage assessment and insurance claim documentation
- Construction cost estimation and project bidding
- Local building code compliance across multiple US jurisdictions
- Material takeoff calculation and waste factor optimization
Every article goes through a multi-step editorial process: initial research and drafting, technical review by a second team member with relevant field experience, fact-check of all numerical claims against published sources, and final editorial review for clarity and accessibility.
