Soffit Vents + DCI Smartvent: good idea or bad?
When I bought my house, we had to have the roof replaced (standard vented roof assembly) – the roofer said the soffits were sealed, and installed DCI Smartvent mid-roof for air intake. It’s now come to light that the soffits are not sealed at all – wide open!
Do the open soffits and the Smartvent mid-roof work together or cancel each other out? Is it wise to seal the soffits and leave the Smartvents open?
If sealing the soffits we’ll probably go from the outside. We have some leftover polyiso – was thinking about putting in new blocking, sealing soffits with pieces of polyiso, and then attaching a decorative soffit on top of the foam – probably back vented for drying – see attached back of envelope sketch.
Thanks for your feedback in advance!
