Final answer:
The correct spacing for shingles to allow for expansion is 1/4 inch. This prevents buckling and complies with manufacturer instructions and building codes.
Step-by-step explanation:
When installing a stained or dry shingle, leave 1/8″ to 1/4″ between each piece depending on the humidity level recorded. If your shingles are large or very dry, it is best to go with 1/4″. For green shingles, leave 1/16″ to 1/8″. The exposure is the exposed surface of the shingle once installed.
When installing shingles on a roof, it is important to allow for expansion due to changes in temperature. The correct spacing to provide for expansion between shingles is 1/4 inch. This spacing helps prevent buckling and other issues that can occur when materials expand and contract. It is essential to follow manufacturer instructions and building codes for the best results in shingle installation.
