Where Gutters Fail Fastest: the 2026 51-State Stress Index
Rainfall, freeze-thaw, tree canopy, hail, and housing age — combined into one open dataset ranking every state by how hard it works a gutter system.
Rainfall, freeze-thaw, tree canopy, hail, and housing age — combined into one open dataset ranking every state by how hard it works a gutter system.
Each state scores 0–100 on five factors, weighted into the composite: rainfall volume 30% (NOAA annual normals, min-max normalized), freeze-thaw 25% (cycle-frequency class from NOAA normals), tree canopy 20% (USFS canopy class → debris load), hail/severe exposure 15% (NOAA SPC climatology class), housing age 10% (Census ACS 2023 median year built, 1955→100 to 2000→0). Modeled lifespans scale baseline material life (vinyl 15 / aluminum 20 / steel 25 / copper 50 years) by each state's stress multiplier (0.75×–1.25×). The full per-state table and every subscore ship in the CSV.

Scores 0–100 per factor. Data: NOAA normals & SPC climatology, USFS canopy, Census ACS 2023. Dataset CC BY 4.0 — download the CSV.
Five weighted factors, each normalized 0–100: rainfall volume (30%), freeze-thaw cycling (25%), tree-canopy debris load (20%), hail/storm exposure (15%), and housing age (10%). Sources: NOAA climate normals, NOAA SPC severe-weather climatology, USFS tree-canopy classes, and US Census ACS median year built. Full methodology and the complete dataset are on this page, downloadable under CC BY 4.0.
New York ranks #1 with a composite stress score of 75.8, driven by its combination of freeze-thaw cycling, debris load, and storm exposure. The top five are New York, Connecticut, Maine, New Hampshire, Michigan.
The gentlest five are Nevada, Arizona, Utah, California, Idaho — low freeze-thaw counts and lighter debris loads dominate the bottom of the table. Even there, undersized or clogged systems still fail; the index measures environment, not maintenance.
We scale baseline material lifespans (vinyl ~15 yrs, aluminum ~20, steel ~25, copper ~50) by each state's stress multiplier (0.75× to 1.25×). A high-stress state shortens aluminum's modeled life toward 16 years; a benign one stretches it past 26. It's a planning number, not a warranty.

It means your environment consumes gutter life faster — inspection intervals matter more, material choice matters more, and deferred repairs get expensive sooner. The actual verdict on your system takes a ladder and a licensed pro, which is what the free referral line is for.
