What is the normal lap for bevel wood siding?

The normal lap for bevel wood siding is typically 1 inch. This measurement is important because it ensures that there is sufficient overlap between the individual boards, which prevents water infiltration and promotes better drainage. The lap helps to create a barrier against moisture that could potentially cause damage over time.

In practice, this lap allows for the natural expansion and contraction of the wood with changes in temperature and humidity, while still maintaining an aesthetically pleasing finish. A 1-inch lap also helps to standardize the installation process, making it easier for contractors to achieve uniformity in their work, which is essential for both function and appearance.

While other options exist, they do not reflect common practices or industry standards for bevel wood siding, making the 1-inch lap the most appropriate choice for typical applications.
