A three-tab shingle's resistance to wind is maximized at which measurement?

The resistance of a three-tab shingle to wind is maximized at the optimal installation angle. Proper installation angle is crucial because it directly affects how well the shingles lie flat against the roof surface, reducing the likelihood of wind uplift. When shingles are installed at the correct angle, they provide better coverage and help prevent gaps where wind can enter and potentially lift the shingles off the roof. Therefore, installing at the optimal angle ensures that the shingles perform effectively in preventing wind damage.

The other options, while related to other aspects of roofing installation, do not have the same direct impact on wind resistance. Minimum installation height and minimum temperature relate more to challenges in proper installation and material performance under adverse conditions, while maximum overlap pertains to the physical overlap between shingles but does not necessarily contribute to maximizing wind resistance in such a significant way as the proper installation angle does.
