Ridge Vent Exhaust & NFA Balancing Tool

Explain that ridge vents use the Bernoulli principle to naturally pull hot air out of the attic. This continuous cycle prevents the 'Heat Trap' that causes premature granule loss. Position it as a mandatory system protection, not an optional accessory.

GAF and CertainTeed require balanced NFA (50/50 intake-to-exhaust) to validate 'Lifetime' warranties. If you install a ridge vent without sufficient soffit intake, the attic will pull air from the home's interior, creating massive moisture issues and potentially voiding the material warranty.
