SIP overhang/soffit – Waterproofing
OSB 8″ thick Polyurethane roof SIP that overhangs the wall by 24″ – I am using peel & stick Ice & Water membrane to waterproof the roof and this roof SIP.
The build-up: For the 24″ overhang/soffit, I am looking to just continue with the peel & stick/Ice & Water membrane and wrap the overhang, fascia, and underside of the SIP soffit with the same peel & stick membrane. I will then use 26 gauge aluminum to cover the area to provide protection.
The soffit doesn’t need to be vented of course because it is a SIP and the peel & stick membrane provides the waterproofing.
Does anyone see a problem with this build-up?
