Insurance Claim Roofing

HOW INSURANCE CLAIM ROOFING WORKS

Step 1: Storm Damage Occurs
• You notify your insurer
• Insurance adjuster inspects roof
• Adjuster issues claim settlement

Step 2: You Call ONE Nation Energy
• We provide FREE damage assessment
• We document with photos/drone
• We estimate scope of work vs insurance settlement
• Often insurance UNDER-estimates repairs

Step 3: We File Supplement Claim (if needed)
• If our estimate > insurance estimate
• We submit supplement with detailed scope
• Usually results in higher payout
• No cost to you (we pursue it)

Step 4: Insurance Approves
• Claim approved with full scope
• You pay deductible (typically $500-2,500)
• Insurance pays contractor directly
• We do the work

Step 5: Final Payment
• If estimate matches final bill: Done
• If final bill slightly higher: We eat small overages
• If major variance: Discuss with you first

Roofing FAQs

  • Most shingles last 20-25 years. Premium shingles (GAF Timberline, Owens Corning Duration+) can last 30+ years. Our 25-year workmanship warranty covers the installation quality regardless of shingle brand.

  • Usually yes. Removing old shingles is standard practice. We inspect the roof decking underneath — if rotten, we replace it (additional cost, typically $500-2,000). Removing old material ensures proper installation
    and prevents moisture issues.

  • We don't recommend it. Multiple layers trap moisture, void warranties, and hide damage. We remove old shingles for proper installation. Some jurisdictions also prohibit layering due to weight limits.

  • Common on older homes. We photograph it and show you — you approve the additional repair before we proceed. Usually $500-2,000 for decking replacement. This is why a thorough inspection is critical.

  • Asphalt shingles ($8-15k, 20-25 years) = most common and affordable. Metal roofing ($12-20k, 40+ years) = durable but noisier. Tile/slate ($15-25k, 50+ years) = premium, very heavy. We help you choose based on budget, climate, and longevity goals.

  • Possibly. Some insurers offer discounts (5-15%) for new roofs under 10 years old. Ask your insurer before and after install — you might save $200-500/year on premiums.

  • We cover exposed areas with tarps. Installation pauses during heavy rain. Typical roofs are waterproof in 1-2 days; we plan for weather windows.

  • Yes. Free inspection if you're considering a new roof. Paid inspection ($200-400) if you want a detailed engineer's report (useful for insurance or selling your home).

  • Yes, if damage is isolated (small leak, section damage, etc.). Usually costs $1,500-3,000. Full replacement is more cost-effective if your roof is 20+ years old.

  • We work with HOA & city requirements. Some areas restrict color or material. We navigate that and ensure compliance. GAF, Owens Corning, and Malarkey all
    offer approved colors and styles for most jurisdictions.
