A weathervane or cupola can add a distinctive touch to your home. Weathervanes should be balanced or they will not function well. Cupolas can serve both as decorative architectural features as well as provide vital attic ventilation.

Continuous ventilation is extremely important to avoid roof rot, reduce heating and cooling costs, and to maintain warranties of some asphalt shingles. Why was attic ventilation never an issue in older homes? Building practices have changed. If you are building new or updating an older home, give your home "lungs" to breathe through air exchange in roof or ridge vents and soffit vents.
Proper ventilation depends upon the type you use. Attic ventilation should be in the ratio of 1:300 minimum per model code. Most of your vents should be in the lower venting area, and the remainder should be upper roof or ridge vents. Read on for clarification.
Determine the amount of ventilation needed for your home with this formula. Calculate the square footage of your attic and provide proper attic ventilation with the right number of roof vents, ridge vents or soffit vents.
Products for continuous ventilation of your home are made by these manufacturers. Attic vents, roof vents, ridge vents and soffit vents keep roof rot at bay. Find more attic ventilation information at these sources.
A whole house fan or ventilation with mechanical or solar powered roof ventilators have requirements different from those of static continuous ventilation mechanisms. Attic ventilation with powered devices needs adequate soffit vents -- or you will waste money!
Crawl space ventilation became essential to avoid moisture damage in modern, energy efficient homes. Crawl space vents may now be eliminated with newer high performance vapor barriers. Convert your crawl space to an unventilated one with a quality vapor barrier, and minimize dampness, temperature swings, and gain storage space.
