I am in the market for a new roof because our current roof has hit its lifespan. I'll try to be concise without leaving off too much information.
Currently, we have an attic fan and 3 gable vents. There are no roof overhangs for soffit vents. By the way, our attic is unfinished and is a large open space. I would like a passive ventilation system using ridge vents for exhaust, however I have had 4 contractors suggest 4 different solutions:
Contractor 1: Use existing set-up for ventilation
Contractor 2: Use Vented Drip Edge for Intake Ventilation
Contractor 3: Use Smart Vents by DCI
Contractor 4: Use 2 Gable fans to create airflow through the attic space with ridge vent
I have researched each solution for air intake using ridge vents and each has its pros and cons.
My quandary: What is the best solution for ventilating an attic with no roof overhangs? I am open to suggestions and maybe ridge vents and a passive ventilation system is not the solution.
Thanks for your help!!
