A framing square is primarily used for measuring and marking angles, which makes it essential for roofing and framing layouts. The tool is designed with a right angle, often measuring 90 degrees, as well as different scales for marking common angles and measurements necessary in construction.

In framing and roofing, ensuring that measurements and angles are accurate is crucial because they directly impact the structural integrity and visual alignment of the finished project. The framing square allows builders to create precise cuts and layouts, facilitating the assembly of square and plumb structures.

Other options, such as aligning windows and doors, calculating area, or determining load capacity, may involve different tools and methods. While alignment may use levels and plumb bobs, area calculations typically require measuring tapes and area formulas, and load capacity assessments rely on structural engineering principles or calculations rather than a framing square. Therefore, the correct answer reflects the primary and most common use of a framing square in the construction process.
