Vent Manifold
Posted by Rod on May 05, 2004 at 17:11:04:
To repair some fire damage, we had new roof trusses, sheeting and composition roof installed. The existing vents (five 2" vents) were cut off before demo of existing roof. The roofing contractor installed two 3" roof jacks near the peak (heavy snow country) to handle the venting. My question is: Can five 2" vents manifold into two 3" vents through the roof?
Thanks in advance.
