A large share of Jenks homes were built in the last few decades, and many share the same layout: a two-story house, a bonus room over the garage, and an attic packed with ductwork and one or two air handlers. On a summer afternoon that attic can pass 140°F, and every duct running through it picks up heat before the air ever reaches your rooms.
Spray foam applied to the underside of the roof deck solves that by turning the attic into a semi-conditioned space. Foam fills each rafter bay, seals the roof deck and gable walls, and stops attic heat from reaching the ducts and the rooms below. Upstairs bedrooms and bonus rooms usually feel the difference first.
Owner Dale Harper or a crew lead looks at every attic before we quote. We check the decking for leaks, look at ventilation and bath fan exhausts, and tell you honestly whether roof deck foam, attic floor insulation or a combination is the better value. Every estimate is free and in writing.
Jenks tip
If your bonus room is the main problem, ask about foaming its knee walls, slopes and the garage ceiling below it. In some Jenks homes that targeted fix solves most of the comfort issue for less than a full attic conversion.
Signs Your Jenks Attic Needs Spray Foam
- ✓A bonus room or upstairs bedroom that stays hot into the evening
- ✓Two thermostats that never seem to agree
- ✓Ducts in the attic that feel hot to the touch
- ✓Insulation that sits below the tops of the joists
- ✓Dust around supply vents and recessed lights
- ✓Summer electric bills that keep climbing
Open-Cell, Closed-Cell or Attic Floor Insulation
Open-cell foam is the standard choice for Jenks roof decks. It provides about R-3.5 to R-3.8 per inch, is usually sprayed 5.5 to 7 inches deep, seals air well and quiets rain and hail noise. It typically runs about $0.45 to $0.80 per board foot installed.
Closed-cell foam provides about R-6 to R-7 per inch and resists moisture, so it is the better fit for vaulted ceilings with shallow rafters and finished attic rooms. If your ductwork is not in the attic, air sealing the ceiling and adding blown-in insulation on the attic floor can deliver similar comfort for less, and we will show you that option too.
