How to ventilate a hip roof with a widow’s walk?
I have a question about a relatively new home (4 years old) in Massachusetts with a ‘four-square’ hip roof that terminates in a widow’s walk (it is flat inside the railing and covered with Bituthene).
There are soffit (eave) vents at the perimeter, insulation in the attic floor (between the ceiling joists) and a ‘prop-a-vent-like material’ to hold the insulation back from the soffit vents, so as not to impede airflow towards the top of the hip portion of the roof.
HOWEVER, there is no ‘visible’ vent to the outside where the hip roof joins the flat widow’s walk area. Where would one expect the venting element (i.e. ridge vent) to be in this situation? and/or how should it be vented? The attic space gets very hot.
Additionally, the HVAC unit for the 2nd floor heating and cooling is in the unconditioned attic space. How can this be rectified and still provide fresh intake air for the HVAC unit? The area of the attic space is +/-40 feet square with an 6-8/12 slope/pitch up to the widow’s walk.
