With the temperature extremes in home attics during the summer months (upwards of 170 degrees) attic ventillation is essential. Excess heat in your attic will radiate thru ceilings regardless of the level of insulation. This will result in higher cooling costs. Improving your attic ventilation will in most cases have a rapid investment payback.
1. Substantially reduces attic temperature (50-60 degrees)
2. Lower cooling costs (less heat radiates through ceilings)
3. Increased HVAC life.
4. Increases the life of the roof desk and shingles.
5. SAVE ENERGY! (an attic vent on a single story house can pay for itself in one cooling season).
