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
Guard against ice damming in harsh winter climates
Possibly reduce excessive heating and air conditioning costs
