11 The United States District Court for the Western District of the State of Oklahoma has certified the following question: "In determining actual cash value, using the replacement costs less depreciation method, may labor costs be depreciated?" We answer that a roof is a single product consisting of both materials and labor, and that pursuant to the "broad evidence rule," which allows a fact-finder to consider the age and condition of the roof, depreciation of the whole product is appropriate. Because labor is a part of the whole product, it is included in the depreciation of the roof.
[2 The federal district court has provided a joint statement of agreed facts by the parties. The plaintiff, Charles Redecorn, purchased a homeowner's policy from State Farm Fire and Casualty Company, one of the defendants. Redeorn's policy provided for roof surface repair and replacement cov*1019erage on an actual cash value basis. His policy includes an endorsement entitled "ROOF SURFACE LOSSES-ACTUAL CASH VALUE ENDORSEMENT:
"Roof Surfaces: We will pay the actual cash value at the time of loss for loss or damage to roof surfaces. We will not pay an amount exceeding that which you actually and necessarily spend to repair or replace the damaged roof."
Redceorn's policy does not define "actual cash value" nor does it prescribe means for determining actual cash value.
13 On November 9, 1998, Redcorn's roof was damaged by either a windstorm or hail. On February 11, 1999, State Farm issued a payment for the actual cash value of the damage to the roof,. The payment was caleu-lated by determining the replacement cost, including materials and labor, and depreciating it. Redcorn contends that Oklahoma law permits actual cash value to be measured by replacement cost less depreciation, but he advocates separating the cost of the roof replacement into components of materials and labor, and depreciating only the materials. The federal district court cited two federal district court cases that are now on appeal which address the same issue, Davis v. Mid Century Ins. Co., CIV-96-2070-T (W.D.Okla. March 26, 1998) (Westlaw 1998 WL 1285714), and Branch v. Farmers Ins. Co., 123 F.Supp.2d 590 (W.D.Okla.2000). The district court additionally observes that there have been numerous other lawsuits raising the same issue. The United States Court of Appeals for the Tenth Circuit has certified similar questions to this Court in case number 96,790, 55 P.3d 1023. The answers to these questions are handed down contemporaneously with the answer to the federal district court question in this case.
14 To answer the question submitted by the federal court, we must construe the term "actual cash value." An insurance policy is a contract. The same principles generally apply to the construction of a policy of insurance as apply to any adhesion contract. Dodson v. St. Paul Ins. Co., 1991 OK 24, ¶ 10, 812 P.2d 372, 376. Wiley v. Travelers Ins. Co., 1974 OK 147, 16, 534 P.2d 1293, 1295, reviews certain established rules for construing terms in insurance policies. Parties to a contract for insurance are free to choose the risks to be covered by the policy. Onee agreed upon, the parties are bound by the terms of the contract; and courts will not rewrite those terms. The construction of a policy should be natural and reasonable, viewed in the light of common sense. The result should not be absurd. The interpretation of an insurance contract and whether it is ambiguous is a matter of law that will be resolved by the court. Dodson, 1991 OK 24, ¶ 12, 812 P.2d at 376.
15 Subsection B of 36 0.8.S8upp.2000, § 4808,1 provides that "no policy or contract of fire insurance shall be made, issued or delivered by any insurer or by any agent or representative thereof, on any property in the state, unless it shall conform as to all provisions, stipulations, agreements and conditions, with such form of policy." The standard fire insurance policy found in subsection G uses the term "actual cash value." That term has a specific meaning that has been construed by this Court, and is not ambiguous.
T6 The fact that "actual cash value" is part of an endorsement in Redeorn's policy insuring roof surfaces for a hazard other than fire or lightening, does not affect the construction of the term. An endorsement that is not a part of the standard fire policy and which insures against other perils is permitted by 36 O.S.Supp.2000, § 4803 (C)2 *1020Though the term "actual cash value" is used in a permitted endorsement, it may not be given a different meaning than that used in the standard fire policy. Any other rule would create confusion and unnecessary ambiguity.
17 Actual cash value in Oklahoma is determined by the "broad evidence rule" as described in Rochester American Ins. Co. v. Short, 1953 OK 4, 252 P.2d 490. The Court-approved Syllabus in Rochester American Ins. Co., 1953 OK 4, ¶0, 252 P.2d at 490, explains the relation between actual cash value and the broad evidence rule. Syllabus 8 provides that actual cash value of a building totally destroyed by fire is a matter of fact to be determined by a consideration of all relevant factors and cireumstances existing at the time of loss. Some relevant factors listed in Rochester include purchase price, replacement cost, appreciation or depreciation, the age of the building, the condition in which it has been maintained and market value. Rochester American Ins. Co., 1953 OK 4, ¶¶ 11-18, 252 P.2d at 493-494.
18 In rejecting the plaintiff's argument that cost of reproduction was the exclusive measure of recovery, Rochester American Ins. Co. quoted McAnarney v. Newark Fire Ins. Co., 247 N.Y. 176, 159 N.E. 902, 56 A.L.R. 1149, that "Indemnity is the basis and foundation of insurance law." The goal of indemnity is to place the insured in as good a condition, so far as practicable, as he would have been if no fire had occurred. McAnar-ney added that to effectuate complete indemnity, every fact and cireumstance tending to aid in formation of a correct estimate of the loss should be considered by the trier of fact. McAnarney, 247 N.Y. at 184, 159 N.E. at 904-905.
I 9 Like this Court in Rochester American Ins. Co., the Supreme Court of Indiana also quoted McAnarney in deciding Travelers Indemmity Co. v. Armstrong, 442 N.E.2d 349 (Ind.1982). That case cited four methods in determining actual cash value of losses,3 but identified the fourth test, the broad evidence rule originating with MceAnarney, as the majority rule. Travelers Indemmity Co., 442 N.E.2d at 356. The Indiana court called the broad evidence rule a flexible rule that permitted an appraiser, court, or Jury to consider any relevant factor in determining actual cash value of damaged property. Travelers Indemnity Co., 442 N.E.2d at 356.
[10 Redcorn insists that depreciation of labor costs is inconsistent with the principle of indemnity. He argues that to be indemnified the materials for a roof may be depreciated, but not the labor to put the roof in place. If he were put in the same position as he was before his roof was destroyed, his replacement roof would have shingles the same age and in the same condition as before the damage. He theorizes that if it were possible to purchase depreciated shingles, the cost of the labor to install them would be the same as the cost of installing new shingles. He concludes that while the insurer is entitled to depreciate the cost of the materials for a roof, the cost of labor should be paid without any adjustment.
11 A roof does not have a separate market value from the building it covers. The relevant evidence for determining actual cash value for a roof would include cost of reproduction, the age of the roof, and the condition in which it has been maintained. A building is the product of both materials and labor. The age and condition of the building were considered relevant facts in the Rochester American Ins. Co. case. Likewise, a roof is the product of materials and labor, and its age and condition are also relevant facts in setting the amount of a loss.
12 Depreciation in insurance law is not the type that is charged off the books of a business establishment, but rather it is the actual deterioration of a structure by reason of age, and physical wear and tear, computed at the time of the loss. Travelers Indemmity *1021Co., 442 N.E.2d at 353. For example, if a roof has an expected life-span of twenty years, and it is near the end of that time but could be expected to last five more years, given its condition, that is a fact to be considered in setting the amount of a loss. Likewise, if a roof is in worse condition than would be expected from its age, that is also a factor to be considered.
{13 Despite the objections of Redcorn, indemnity is served by considering the age and condition of a roof, both materials and labor, in setting an amount of loss. To meet the goal of indemnity, Redeorn should be placed, as nearly as practicable, in the same condition as he was in just prior to the insured loss. Pursuant to the broad evidence rule, a fact-finder is entitled to consider what the life of the destroyed roof, both materials and labor, would have been, as well as any other relevant evidence presented. In Rochester American Ins. Co., 1958 OK 4, 119, 252 P.2d at 492, the Court observed that the jury instruction stated that the actual cash value of a building is the cost of replacing the building with material of like kind and quality less depreciation, and that the amount of depreciation was to be determined by considering the age of the building, the condition in which it had been maintained, changes in the neighborhood and any other facts and circumstances in evidence that affected the value of the property, including the viewing of the premises by the jury. When the Rock-ester Court mentions replacing the building with material of like kind and quality, replacing necessarily includes labor.
1 14 Redeorn chose an "actual cash value" policy, and paid premiums based on his choice. He insured a roof surface, not two components, material and labor. He did not pay for a hybrid policy of actual cash value for roofing materials and replacement costs for labor. To construe the policy in such a manner would unjustly enrich the policy holder.
4 15 In summary, actual cash value is determined by the broad evidence rule. That rule requires that all relevant evidence be considered in determining a loss. A roof is the product of both materials and labor just as a building is the product of both materials and labor. Age and condition of a roof is relevant evidence in determining actual cash value.
