What does the process of taper sawing in wood shingles ensure?

Taper sawing in wood shingles is a specific method used to create shingles that are thicker at one end and taper down to a thinner edge. This design allows the shingles to lie flat against a surface when installed. The tapered edges help fit snugly against each other, reducing gaps and ensuring a tighter seal, which is essential for effective roofing systems.

While uniform thickness, waterproofing, and increased weight are important considerations in roofing materials, they do not directly result from the taper sawing process. The primary advantage of this method is its ability to create shingles that lay flat, which is crucial for both aesthetics and function in roofing applications. The flat laying ensures that water runs off effectively, enhancing the shingles' performance and longevity. Thus, the focus on the flat laying aspect accurately captures the essential purpose of taper sawing in wood shingles.
