External indicators of a renovation/remodel of a building include which of the following?

• A. Windows
• B. Doors
• C. Roofs
• D. All of the above

Answer: (D)

External indicators of a renovation appear as visible changes to parts of the building you can see from the outside. When a remodel is done, the envelope is often updated, so you’ll frequently notice new windows, upgraded or replaced doors, and sometimes a new roof. Seeing all of these elements changed together is a strong sign that a renovation took place, not just routine maintenance. Each exterior component contributes to the overall look and performance of the building, and updating multiple of them during a remodel is common, which is why the best choice is all of the above. If you only noticed one of these items, it could be due to various reasons (like a single replacement or minor repair), but the combination of multiple exterior updates makes the renovation cue much clearer.
