I don't know how widely accepted it is- many do not accept it esp if rote and default use as a formula-Is it your contention that the all of the adjustments in the sales grid must be based on comps? I think a lot of appraisers would disagree.
In your case, you'll need to find comps with tile shingles piled on the roof to make a supportable adjustment. (BTW, I was just in the Ft. Meyers/Punta Gorda area and saw a LOT of homes with shingles piled on the roofs and nobody was doing any installing.)
Making an adjustment for C2C in the sales grid based on an cost estimate (including profit and EI) is a longstanding and widely accepted method. Oftentimes, it is the only reasonable approach.
Unless an appraiser can support that the C 2 C is also the approximate market reaction IMO it can be flawed -
Because if the repair or finish etc is substantial enough to materially affect value, at different times we see market reaction as below cost, or above cost, or at the equivalence of cost,
Value is related to identifying the typically motivated buyer = property flippers and re rehabber like to pay below cost, owner occupants with money who want a 100% finished / renovated place will pay far above cost and an average owner occupant who might take on a small completion or repair project will often pay the equivalent to the cost to fix or finish.
