How to Convert Oven Recipes to Air Fryer
This calculator scores your home's disaster resilience (0-100) across five categories and identifies the highest-ROI upgrade based on current weaknesses.
The basic rule:
- Each category (roof, windows, power, flood, fire) is scored 1-4 and weighted equally for the composite score
- The top recommended upgrade targets your lowest-scoring category for maximum resilience improvement
- Insurance savings are estimated at 5-15% per major upgrade based on typical insurer discounts
- ROI calculation includes both insurance premium reduction and reduced expected loss from damage avoidance
- Whole-home generators and impact windows typically offer the best combination of resilience and insurance savings
Resilience scores are relative estimates. Actual insurance savings vary by insurer, state, and policy. Many upgrades also increase home value by 1-5%. Contact your insurer before upgrading to confirm specific discount eligibility.

Frequently Asked Questions
What is a home resilience score?
A home resilience score measures how well your property can withstand and recover from natural disasters including hurricanes, wildfires, floods, and power outages. Scores factor in structural materials, protective features, backup systems, and defensible space. Higher scores correlate with lower insurance costs and damage risk.
What home upgrades have the best ROI for resilience?
Impact windows typically offer the best ROI: $15,000-25,000 installed with 15-30% insurance savings plus increased home value. Roof upgrades (impact-rated shingles or metal) cost $10,000-20,000 and save 10-25% on insurance. Whole-home generators ($8,000-15,000) prevent food spoilage, pipe freezing, and habitability losses.
Do resilience upgrades increase home value?
Yes. Impact windows add 1-3% to home value, metal roofs add 1-6%, whole-home generators add 3-5%, and a fortified roof-to-wall connection system can add value in hurricane-prone areas. These features are increasingly important selling points as climate risks grow.
How much can I save on insurance with resilience upgrades?
In hurricane-prone states, a full wind mitigation package (impact windows, hip roof, roof-to-wall clips) can save 30-50% on windstorm premiums. Individual upgrades typically save 5-15% each. In fire zones, defensible space and Class A roofing can save 10-20% on fire premiums.
What is the FORTIFIED Home designation?
FORTIFIED Home is a program by the Insurance Institute for Business & Home Safety (IBHS) that certifies homes built or retrofitted to exceed code for wind and hail resistance. FORTIFIED Gold designation can reduce insurance premiums by 30-55% in participating states like Alabama, Mississippi, and South Carolina.
