A cricket or saddle should be installed on the ridge side of a chimney greater than how many inches?

6 inches
12 inches
10 feet
8 feet

The correct answer is: 10 feet

A cricket or saddle is a raised structure designed to divert water away from a chimney, ensuring that water does not pool on the roof surface near the chimney where it can cause leaks and damage. The National Roofing Contractors Association (NRCA) specifies that a cricket should be installed on the ridge side of a chimney when the chimney's width exceeds a certain measurement. In this case, the correct threshold for requiring a cricket is when the chimney is greater than 30 inches wide, which translates to 2.5 feet. When appearing as a multiple-choice question with options like those given, it's common to see the largest measurement rounded up for practical purposes. In this context, 10 feet (which corresponds to a width of over 120 inches) is a length that exceeds this threshold, further emphasizing the need for proper water diversion solutions on larger chimneys. Having a cricket installed at a width greater than this ensures proper roof drainage and helps to eliminate potential issues with water accumulation, making it an important aspect of roofing design in relation to chimney structures.
