Dual Powered Roof Exhaust Vent
Effective attic ventilation is critical for a long-lasting roof — yet most homes have insufficient attic ventilation! A Dual Powered Roof Exhaust Vent will help to:
- Remove excess heat and moisture to protect your roof from premature deterioration
- Safeguard your attic possessions against mildew damage
- Limit the growth of harmful mold
-
Protect your roof from premature deterioration and roof rot
- Minimize peeling and extend the life of exterior and interior paint
- Guard against ice damming in harsh winter climates
- Possibly reduce excessive heating and air conditioning costs
Master Flow® Green Machine™ Dual Powered Roof Exhaust Vents are a key part of the GAF-Elk Smart Choice® Roof System Solution, and have even earned the prestigious Good Housekeeping Seal.
