It’s not so much a question of which is better, but a question of which is better for particular types of roofs. For example, if your home has cathedral ceilings, the ridge vent is the only viable solution. On a roof where four slopes converge to a single, small ridge as shown above, box vents are required for proper ventilation.
Many homes are designed where either a ridge vent or box vent will work equally well. Considering the fact that ridge vents are more aesthetically pleasing, our recommendation would be the ridge vents.
