Pro Tip: Every bit of savings counts on a big job. When you choose an adjustable roof drain you eliminate the need to order multiple extensions in varying heights. Contractors appreciate the fact that this roof drain can accommodate the inevitable inconsistencies in roof insulation thickness. Simply spin the adjustable extension to fit insulation from 1-1/4 to 4 inches (32 to 102 mm) thickness.
