I have a roof with 1/2" medium cedar shake shingles. After a recent hail storm, we call our insurance company to inspect for damage. They agreed with our roofer that the damage warrants a total roof replacement. They also agreed on a price with our roofing company to replace it with the same 1/2" shakes. Now that the replacement cost value has been established, we are considering downgrading to a less expensive asphalt shingle. I've been told the cost savings will be captured by myself to help with the deductible. The insurance company now tells me they only pay up to the invoice amount from the roofer. If we were replacing with the cedar shakes, that would indeed be correct. However, I've been paying premiums for years based on replacement cost of the shake roof. Because I'm downgrading to asphalt, shouldn't the savings come back to me? Again, they agreed to the full replacement cost of the wood shakes and it is higher than the asphalt we want to install. Please help!!
