Which method of installing shingles creates a distinctive wave pattern?

The correct answer is the method that specifically emphasizes the creation of a wave effect through the installation of shingles. This technique, often called wave pattern installation, is characterized by the way shingles are layered and spaced to create a visually appealing undulating design on the roof. By strategically placing shingles with a slight overlap and varying the positioning slightly from row to row, the wave pattern becomes prominent, adding an aesthetic appeal to the roofing project.

In contrast, the interlocking method focuses on securing shingles together for better wind resistance, while the butt joint method involves aligning the ends of shingles directly, leading to a more traditional flat appearance without the wave effect. Standard horizontal layering simply stacks shingles in uniform rows, which does not create any distinctive pattern but rather maintains a consistent and straightforward look.
