COST OF REPAIRS vs COST OF REPLACEMENT
Once the Data Collection Phase is complete and the database is populated, RoofSuiteSM processes the data and develops a "lowest life cycle cost" strategy for managing your roof inventory.
Based on the combination of materials and methods used to construct the roof, RoofSuiteSM projects the expected life of each roof section in the database. The observed defects are then compared with the age of the roof, the roof system type, and the actuarial risk of failure to calculate the remaining useful life of the roof, or specific roof area.
RoofSuiteSM now begins the optimization process, which evaluates every combination of repairs to determine which repairs will cost effectively add service life to the roof area. The repairs are modeled both reconstructively (permanent) and temporarily (patch), based on the life cycle cost benefits. Replacements are selected only when the annual costs to maintain the roof exceed the annualized cost of replacement. The methodology incorporates deterioration curves, life cycle factors, cost of capital, replacement options, and actuarial data to determine the most cost-effective course of action. It is through this methodology that RoofSuiteSM determines the optimal blend of repair and replacement dollars required to produce the lowest Life Cycle Cost (LCC) for our client.
Sometimes the best financial decision is to replace the roof. But the first goal of the RoofSuiteSM analysis is to find opportunities to extend the roof life, protect assets, and minimize liabilities-all at minimum expense or capital outlay.
