Rigid insulation can be tapered so that it can be placed on a structurally flat roof and provide a slope for drainage.Group of answer choicesTrueFalse

Answer

True.

Rigid insulation can indeed be tapered to create a slope on a flat roof. This tapering is essential for effective water drainage, preventing water accumulation that can lead to leaks or structural damage over time. The insulation is designed with a sloped profile, allowing water to flow towards drainage points, thereby enhancing the roof's performance.

This method not only maintains the thermal efficiency of the insulation but also addresses the critical requirement of proper roof drainage. It is a common practice in construction to ensure that flat roofs, which may otherwise retain water, effectively direct water to designated drainage areas. Thus, the statement is true, highlighting the versatility and functionality of rigid insulation in roofing applications.
