Roof Curbs

Moffitt roof curbs are available for a variety of roof types to best meet each building’s requirements. Roof type and environment will determine which curb should be selected and which material, galvanized steel or aluminum, it should be made of. Many sizes and heights are available, as are additional options such as insulation, liners, damper trays, finishes, and sound attenuation.
