Roof Deck Spray Foam in Naples, FL

Roof Deck Spray Foam moves the insulation from the attic floor up to the underside of the roof. The soffit and ridge vents are sealed, and the attic becomes a semi-conditioned space a few degrees from the rooms below rather than one of the hottest places on the property. In a Naples home where the air handler and supply ducts run through the attic, that change can matter more than adding inches on the floor.

Why the ducts matter

Ducts carry the coldest air in the house. When they sit in a summer attic, any leak or thin wrap means you pay to cool the attic. Putting the insulation above them, at the roof deck, cuts that loss without having to move equipment.

Open or closed cell under the roof

Open-cell foam is the common choice for roof decks here. It is lighter, lower in cost per R, and because it is vapor-open a roof leak tends to show up as a stain instead of rotting the deck in secret. Closed cell may be specified under certain roof assemblies or where added stiffness is wanted. We tell you which we would use and why.

Timing with a new roof

After a storm or at the end of a roof's life is a good moment to plan this. Many Naples homes were re-roofed after Hurricanes Irma and Ian, and owners often ask whether to foam the deck while they are at it. Foam goes on from inside the attic, so it can follow the roofer, but the new roof has to be dry and tight first.

What changes for you

After a roof deck job, the attic runs much closer to indoor temperature. Ducts and the air handler stop sitting in extreme heat, and rooms at the end of long duct runs often cool more evenly. We cannot promise a specific bill reduction, but we explain what to expect.

What we check first

We look for active leaks, staining, sagging decking, gas appliances that rely on attic air, and bath fans that vent into the attic. Those get resolved before any foam goes up. Call (239) 977-5375 or get a free estimate.
