Roof Deck Foam for Sealed Attics in West Palm Beach, FL

Roof deck foam for sealed attics moves the insulation from the attic floor up to the underside of the roof. Open-cell spray foam goes on the roof deck and gable walls, the soffit and ridge vents are closed off, and the attic becomes part of the insulated envelope. In a West Palm Beach house with the air handler and ductwork in the attic, that matters a lot: the equipment stops working in an attic that runs far above the outdoor temperature for half the year and works in air much closer to the temperature of the rooms below.

When it makes sense

• The air handler and most ducts are in the attic.
• The attic floor is cluttered with ducts and platforms, hard to insulate evenly.
• Rooms farthest from the air handler never cool down.
• You are reroofing or planning to stay long enough to benefit.

If the air handler is in a closet and duct runs are short, sealing the ceiling and blowing in usually costs less for a similar result.

Reroofing is a good moment

Many Palm Beach County homeowners replace roofs after storms or as roofs age. A new roof deck is the ideal surface for foam: clean, dry and sound. If you are planning a reroof, talk to us about timing so the foam goes on once the new roof is dried in.

What we check

Before foaming, we inspect the roof deck for leaks, stains and soft spots. Existing insulation on the attic floor can often stay, though we sometimes remove it to reach leaks or clear contaminated material. Closing attic vents changes how gas appliances in the attic get combustion air, so we flag any appliance that needs an HVAC or gas technician. In some attics an ignition barrier coating is required over exposed foam, and we note it on the quote.

Cost

HomeGuide lists roof deck foam at $1,500 to $9,000, and Fixr lists a foamed attic in an existing home at $2,500 to $12,000. Hip roofs, several roof planes and tall gable walls increase the surface and push the total up. We measure the deck area and price it in writing.
