What is "Total cost" in roofing terms?

In roofing terms, "Total cost" encompasses the overall expense incurred to complete a roofing project, which often includes various components like materials, labor, and any necessary modifications or structural supports, such as trusses. When considering replacing a roof, the total cost would include all expenses associated with the entire scope of work, from materials to removal and installation.

Each of the other options reflects a specific aspect of roofing but does not capture the complete financial picture required to fully replace a roof. For instance, focusing on the number of roofing squares required limits the viewpoint to just the material quantity needed, without accounting for labor or other costs. Similarly, discussing the cost to remove a square of shingles or the costs connected to truss design isolates particular elements of the process rather than providing a comprehensive view of the total financial implications for replacing a roof, which includes not only the structural components but also the labor and any permits or additional materials.
