Spray foam eaves
We are getting our roof spray foamed in about a month. I’d like to leave no stone unturned and ensure the foam contractor doesn’t miss anything.
Apologies if I am not using the right terminology. Attached is a photo of where the roof / rafters meet the wall. You see (from top to bottom): subfloor, joist, another layer of boards or maybe a top sill, joist, bottom of eaves.
Can you please share what exactly needs to be spray foamed, i.e. all the way down the eaves? Can I prep the area before they start to maximize chances of success?
Information in case necessary: Northern NJ / zone 5, unvented roof and will be conditioned in the future.
