Ensuring correct coverage and alignment of roofing materials comes down to accurate layout and placement. This means planning and marking a straight starting line, laying out each course so it lines up with the previous one, and keeping a consistent overhang and straight edges as you progress up the roof. When shingles are laid with accurate layout, the rows stay aligned, joints are staggered properly, and the edges meet at eaves, ridges, and hips cleanly, providing full coverage and effective water shedding. The attic is simply the space beneath the roof, and eave trim is a finishing piece at the edge—not the process of laying out and aligning shingles. Placing shingles randomly would lead to gaps and misalignment, compromising performance and appearance.
