I thought somebody would point out that California has odd laws and rules and my California example doesn't apply elsewhere.
Just to drive home this concept take a look at IOWA insurance regulations:
191—15.44(507B)Standards for determining replacement cost and actual cost values.15.44(1)Replacement cost.When the policy provides for the adjustment and settlement of first-party losses based on replacement cost, the following shall apply:a.When a loss requires repair or replacement of an item or part, any consequential physical damage incurred in making such repair or replacement not otherwise excluded by the policy shall be included in the loss. The insured shall not have to pay for betterment or any other cost except for the applicable deductible.b.When a loss requires replacement of items and the replaced items do not match in quality, color or size, the insurer shall replace as much of the item as is necessary to result in a reasonably uniform appearance within the same line of sight. This subrule applies to interior and exterior losses. Exceptions may be made on a case-by-case basis. The insured shall not bear any cost over the applicable deductible, if any.
Notice the Iowa regs are almost identical to California. Other states too.
What I'm showing here is the nuts and bolts of the law/regs, that adjusters are obeying without ever even having read it - if an adjuster ever wondered why roof sheathing gets paid for a home that didn't have sheathing before, this is the reason.
"any consequential physical damage incurred in making such repair or replacement"
removing the adjacent shingles to repair the damaged shingles is "consequential physical damage" and that's why it gets paid on an RCV policy.
removing a lower layer of shingles to repair the damaged shingles is "consequential physical damage" and that's why it gets paid on an RCV policy.
installing sheathing where there wasn't any before to repair the damaged shingles is "consequential physical damage" and that's why it gets paid on an RCV policy.
As I explained, that rule isn't there for ACV policies. If anybody wants, I can try to find the case law that says ACV polices don't have to cover these things.
The state regs are expressed in the positive, ie. they say what RCV policies must cover, and don't mention what ACV policies don't have to pay.
Here is a link to a plaintiff lawyer website that has almost identical wording for the Florida statute (law, not just regs)
http://www.propertyinsurancecoverag...-property/ The article states that a federal case decided this rule is applicable to homeowner claims, not commercial.
I believe this concept is true for pretty much every state:
RCV policies have to pay for everything neccesary to do the repairs, including making it look nice and uniform
ACV policies don't have to pay for things that are undamaged and don't have to pay to make things match
By the way- if an RCV policy is settled on an ACV basis because the homeowner is not eligible for recoverable depreciation, that still counts as an RCV policy for purposes of this rule.
