Insurance Claim Proceeds

I had a fancy roofing material on my house. This past year we got hail damage and the insurance adjuster gave me this:

 

Replacement Cost Value: $49,503.67

Less Depreciation: 3,452.38

Net Claim: $44,949.84

Net Claim if Depreciation is Recovered: $48,402.22

 

I confirmed that if I chose to replace the roof with standard shingles that I could keep the Net Claim difference. I ended up getting about 20,000 after replacing my roof. 

Is that 20,000 taxable? My hope is it's not considered income as I was compensated for my loss of the fancy material/roof value. In theory my house is worth less now then it was with the fancy roofing material.
