🔍
Enter your city — we'll apply the correct IECC climate zone to your results automatically.
Most common roof type. Avg. lifespan: 20–25 years. Susceptible to hail damage in storm zones.
Mid-life for most asphalt shingle roofs. Worth monitoring after storm season.
No repairs — your roof appears to be holding up well.

Roofs never inspected accumulate undetected damage that compounds quietly after hail seasons.

Cited Fact
Regional Note
Step 1 — IECC Climate Zone Detection
Your city is mapped to an IECC climate zone adjusting roof degradation rates, storm risk, and snow load. Zones 2–3 (Gulf Coast, Central TX) sit in the US hail corridor — highest hail frequency globally. Shingles here see accelerated UV and storm degradation. Zones 5–7 shift urgency toward snow load and ice dam risk. Zone adjusts replacement threshold based on real climate wear patterns.
Zone 4 (Mixed/Humid) — baseline multipliers applied
Conservative Estimate
Step 2 — Age, Material & Storm Risk
Roofs degrade at different rates by material and zone. Shingles in hot zones face higher UV cycling. Storm signals are weighted higher in hail corridor zones. Cold zones add snow load and ice dam premiums. Replacement threshold shifts by zone.
Zone 4: 1.00× degradation mult. Replacement threshold: $10,000.
Conservative Estimate
Step 3 — Interior Damage Risk
A single undetected roof leak averages $2,500–$7,500 in drywall, insulation, and mold remediation. Each signal carries weighted risk adjusted by zone. Interior water damage risk avoided is the primary value of timely action.
Sig1: $800, Sig2: $3,500, Sig3: zone-adjusted storm cost
Industry Standard
Step 4 — The Replacement Threshold
Multiply your roof age by any repair quote. If the result exceeds the zone threshold, full replacement is almost always more financially sound than continued repair.
Zone 4 replacement threshold: $10,000

Your Full Cost & Risk Breakdown
Heads up: These are estimates based on industry averages, your inputs, and your IECC climate zone. Actual costs vary by roof pitch, material, labor rates, and damage extent. If you indicated possible insurance coverage, your actual out-of-pocket cost may be significantly lower.
