In most Claremore homes, the furnace, air handler and ductwork sit in the attic. On a July afternoon that attic can pass 140°F, which means cooled air leaves the system and immediately travels through ducts sitting in an oven. Thin fiberglass on the attic floor does little to help, and every gap around wiring, plumbing vents and recessed lights lets attic heat and dust into the rooms below.
Spray foam on the underside of the roof deck changes the whole picture. Polyurethane foam expands to fill the rafter bays, seals the deck and gable ends, and turns the attic into a semi-conditioned space that stays close to indoor temperature. Ducts stop gaining heat, the air conditioner runs shorter cycles, and the upstairs or back bedrooms finally keep pace with the rest of the house.
Owner Derek Vance or a crew lead inspects every attic before we quote it. We check the roof decking for leaks and soft spots, look at ventilation and bath fan terminations, and explain whether open-cell foam, closed-cell foam or attic floor insulation fits your home best. Every estimate is free and in writing.
Claremore tip
Bathroom fans that blow into the attic instead of through the roof put a lot of moisture into the space. Have them vented outside before the roof deck is foamed so humidity has somewhere to go.
Signs Your Attic Is Working Against You
- ✓A back bedroom or bonus room that never cools off
- ✓An AC that runs nearly nonstop on summer afternoons
- ✓Attic insulation that sits below the tops of the joists
- ✓Ducts in the attic with loose joints or thin wrap
- ✓Dust lines around ceiling vents and carpet edges
- ✓Ice along the roof edge or frost on roof nails in a cold snap
Open-Cell, Closed-Cell or Attic Floor Insulation?
Open-cell spray foam is the most common roof deck choice in Claremore. At about R-3.5 to R-3.8 per inch, it is typically sprayed 5.5 to 7 inches thick, seals air well and dampens rain and hail noise on the roof. Closed-cell foam, at about R-6 to R-7 per inch, makes sense for vaulted ceilings with shallow rafters, low-slope roofs or places where moisture control matters most.
If your ductwork is not in the attic and the space is easy to reach, adding insulation to the attic floor can be the better value. Fiberglass or cellulose blown to R-38 or more, after the ceiling is air sealed, works well in many simpler attics. We lay out each option in your free estimate so you can compare cost and benefit.
