Typical Installation
Greenheck's
General Flashed Roof Installation:
1.Remove roofing material where roof penetration is to be made and provide a 10‑inch wide clearance around perimeter of hole in roof.
2.Apply roofing cement around roof opening.
3.Place and center roof curb over hole in roof so it sits on roofing cement. Make sure the roof curb is placed over an adequate support structure to handle the weight and wind load of curb and fan assembly.
4.Secure roof curb to roof deck using a minimum of three lag screws, anchor bolts, or suitable metal fasteners per side and two per corner (fasteners by others).
5.Install insulation if required.
6.Field flash – flashing should extend at least 4 inches beyond the horizontal flange on roof curb. Flashing should also extend over the top flange surface where there is a wood nailer for a leak resistant installation.
7.Apply Curb Seal (rubber gasket) to the top of roof curb to seal fan or ventilator to curb to prevent air leaks and water penetration and to reduce the transmission of vibration from fan to building.
8.Place fan or ventilator onto roof curb and center.
9.Secure fan’s curb cap to the roof curb using a minimum of two lag screws, anchor bolts, or suitable metal fasteners per side (fasteners by others).
Notes:
•For rubber roofs, refer to roof manufacturer for roof curb installation.
