Understanding Your Property's Storm Risk
Every property in the Tulsa Metro area faces some level of severe weather risk — but not all properties are created equal. Factors like roof age, material type, slope, orientation, and surrounding vegetation all influence how well your property withstands hail impacts, straight-line winds, and thermal cycling. Proof Construction's Storm Risk Score uses forensic building science and historical Oklahoma storm data to quantify your property's vulnerability.
Our risk assessment methodology is based on ASTM standard testing protocols, NOAA severe weather data for Tulsa County, and over 4,000 forensic roof inspections performed since 2014.
Risk Factors We Analyze
Roof Age & Condition
Older roofs lose impact resistance as sealants dry out and granule loss exposes the asphalt mat. Roofs over 15 years old have 3x higher risk of hail penetration.
Material Impact Rating
Class 1-4 UL 2218 impact ratings determine how well your shingles resist hail damage. Class 4 materials reduce risk by 70%+ compared to standard 3-tab shingles.
Building Envelope
Roof geometry, slope, edge details, and flashing quality affect wind uplift resistance. Complex roof lines with multiple valleys and penetrations increase leak risk.
Exposure & Topography
Properties on hilltops, open plains, or near large bodies of water face higher wind exposure. Tree coverage can provide protection but also falling branch risk.
Oklahoma Storm Risk Context
Tulsa County sits in Oklahoma's "Hail Alley" — a corridor stretching from Lawton to Tulsa that experiences an average of 3-5 significant hail events annually. According to NOAA data (2015-2025), Tulsa County ranks 4th in Oklahoma for hail insurance claims, with average claim severity of $18,500. Combined with 80+ mph straight-line winds during spring storms, Tulsa properties face one of the highest combined hail+wind risk profiles in the United States.
