Unlike sprayed polyurethane foam roofing problems, the Icynene® spray foam used in residential properties has open-cells which means it's a breathable insulation which will allow air and moisture to pass through it.
Spray foam can provide the thermal, air, and vapor control layers in both new and retrofit construction. Unvented roof strategies with open cell and closed cell SPF insulation sprayed to the underside of roof sheathing have been used since the mid-1990s to provide durable and efficient building enclosures.
Insulating Your Attic with Spray Foam
While spray foam won't cause any damage to the roof shingles, some contractors will still void the warranty because they are stuck in that old way of thinking. If this is the case, it doesn't hurt to have a conversation with them to get on the same page.

Fiberglass insulation is much more affordable than spray foam insulation and easier to install, but it is more permeable than spray foam. Like its name suggests, fiberglass insulation consists of fine glass fibers and comes in a variety of forms, from blanket and loose-fill to rigid boards.
Spray foam insulation is a better insulator than traditional insulation. One of the most significant advantages of spray foam insulation is that it is a better insulator than other types, meaning homeowners can save money on their heating and cooling bills.

Actually, you should get rid of power attic ventilators whether or not you're sealing the attic, but that's another article.
The closed cell spray foam doesn't need a vapor barrier because the spray foam itself functions as a vapor barrier, air barrier and thermal barrier too. However, the open cell spray foam needs a vapor barrier. 5.
