This index is our full breakdown of real Mississippi roof data from Biloxi, D’Iberville, Ocean Springs, and Pascagoula.

Not theory.
Not manufacturer marketing.
Not insurance talking points.
Actual roof behavior during 2024–2025 storms across the Mississippi Gulf Coast.

1️⃣ Leak Activity Index (LAI)

Biloxi: High — wind-driven rain + aging shingles
D’Iberville: Medium — builder-grade flashing failures
Ocean Springs: High — soffit leaks, high attic moisture
Pascagoula: Very High — edge leaks + saturated decking

Main causes: storm clustering + heat fatigue + nails backing out.

2️⃣ Storm-Triggered Emergency Index (STEI)

Worst damage isn’t from “big” hurricanes —
it’s from two or three storms in the same week.

Patterns we observed:

• seal strips weakening
• ridge caps cracking
• vent sealant splitting
• starter rows lifting
• hidden creases under shingles

3️⃣ Shingle Failure Probability Index (SFPI)

Most failure-prone shingles in Mississippi:

1. 3-tabs over 15 years old
2. Architectural shingles over 18–20 years
3. Builder-grade shingles from mass-built neighborhoods

Common failure points: hips, ridges, sidewalls, first-row eaves.

4️⃣ Wind Fatigue Risk Index (WFRI)

The Mississippi Gulf Coast sees 50–60 days/year of 30+ mph winds.

This causes:

• nail pull-through
• lifted tabs
• creased shingles
• flashing separation
• dried vent seals

5️⃣ Hidden Roof Damage Index (HRDI)

Hidden problems found in 2024–2025:

• soft decking
• under-driven nails
• angled nails
• cracked vent boots
• worn felt underlayment
• squirrel damage (constant)

Roofs 12+ years old now have 60%+ chance of hidden damage.

6️⃣ Post-Storm Insurance Denial Index (PSID)

Most common denial reasons we saw:

• “wear and tear” defaults
• desk adjusters denying without inspection
• brittle-shingle matching dodge
• event-size disputes
• requiring documentation homeowners can’t provide

Insurance denials increased sharply in 2025.

7️⃣ Contractor Risk Index (CRI)

Mississippi homeowners face serious contractor risks:

• out-of-state storm chasers
• no license / no insurance
• 4-nail installs instead of 6-nail
• GOOD/BETTER/BEST gimmicks
• felt paper in 2025
• no rooftop photos
• “lifetime warranties” from companies that won’t last 18 months

The index helps homeowners avoid these pitfalls.
