The phrase refers to a tool or method used to estimate the depreciated worth of a roofing system. It assists in determining the current value of a roof by factoring in its original cost and accounting for depreciation due to age, wear and tear, and other factors. For example, a roof originally costing $10,000 might have a present value of $6,000 after accounting for several years of use and environmental exposure.
Determining this depreciated value is crucial in insurance claims related to roof damage. It influences the amount an insurer will initially pay for a roof replacement, before any recoverable depreciation is factored in. Historically, understanding this valuation has been vital for homeowners to ensure they receive a fair settlement for damages, allowing them to adequately repair or replace their roofs.
