Attic & Roof Insulation Services in Tulsa, OK
Proof Construction has insulated and re-roofed homes across the Tulsa metro since 2015, and we're an Owens Corning Preferred Contractor with an A+ BBB rating and 4.9★ across 127+ reviews. We treat insulation as part of the roof system — because attic heat and moisture are what cook shingles from underneath, rot decking, and drive ice dams. Every job starts with a free attic inspection, a measured R-value assessment, and air-sealing before a single bag of insulation goes in.
Spray Foam Insulation
Open-cell and closed-cell spray foam expand to seal every crack, gap, and penetration — creating both insulation and an air barrier in one pass. It's the strongest defense against Tulsa's summer heat gain and winter drafts, and it stiffens the roof assembly against uplift. Ideal for attics, bonus rooms, and cathedral ceilings.
Blown-In Cellulose & Fiberglass
The most cost-effective way to hit R-49 or higher on an attic floor. Blown-in insulation fills around joists, wires, and pipes far better than rolled batts. We install it over a proper air-seal layer with vent baffles protecting the soffit airflow path.
Batt Insulation
Fiberglass and mineral wool batts remain a solid budget option for attics, walls, and floors — when installed meticulously. We cut batts to fit, never compress them, and detail every gap so the R-value you pay for is the R-value you get.
Attic Air Sealing
Insulation without air sealing is like a winter coat full of holes. We seal penetrations — recessed lights, plumbing stacks, duct chases, and the top plates of interior walls — because that's where Oklahoma's attic heat and cold pour into your living space.
Ventilation Balancing
Insulation and ventilation must be designed together. We verify balanced soffit intake and ridge exhaust, install baffles before blown-in work, and fix blocked or missing vents — protecting the deck from moisture while the insulation does its job. See our full home services.
Ice Dam Prevention
Ice dams form when attic heat melts snow on the roof and it refreezes at the cold eaves. A properly insulated, air-sealed, and ventilated attic keeps the deck cold so snow melts evenly — and keeps water from backing up under your shingles. We also install ice-and-water shield at eaves and valleys during roof replacements.
Recommended R-Values for Oklahoma Homes
R-value measures how well insulation resists heat flow — the higher the number, the better the barrier. Tulsa sits in IECC climate zone 3, where the attic insulation code minimum is R-38. But for Oklahoma's mix of brutal summer heat gain and winter freeze-thaw cycles, R-49 to R-60 is the practical recommendation for attic floors, with R-38 to R-49 for vaulted and cathedral ceilings where space allows.
- Attic floor (blown-in or batt): R-49 to R-60 recommended — about 16–20 inches of blown cellulose or fiberglass
- Spray foam (open-cell): R-30 to R-38 at the roof deck, which also seals the attic into the conditioned space
- Cathedral / vaulted ceilings: R-38 to R-49, balanced against the vent channel above the insulation
- Existing homes: if your attic insulation is under ~10 inches, adding a layer almost always pays for itself in 3–5 years
The U.S. Department of Energy estimates that properly insulating and air-sealing an attic can cut heating and cooling costs by 10–15% or more — which in Tulsa, where summer AC runs half the year, translates to real monthly savings on every bill.
Energy Savings, Ice Dams & Ventilation — Why Insulation Is a Roofing Job
Most people think insulation is a "home improvement" task. In Tulsa, it's a roofing task — because the attic is sandwiched between your shingles and your ceiling, and what happens up there decides how long your roof lasts. Heat rising from a poorly insulated attic accelerates shingle aging from underneath, melts snow unevenly into ice dams, and drives moisture into the deck. That's why Proof Construction handles insulation alongside roof replacements, repairs, and storm work: the roof, insulation, and ventilation are one system.
- Free attic inspection & R-value measurement: We measure current depth, check for gaps, moisture, and blocked vents, and photograph everything.
- Air sealing first: Every penetration gets sealed before insulation goes in — this is where most energy loss actually happens.
- Right material, right depth: Spray foam, blown-in, or batt — matched to your attic type, budget, and target R-value.
- Ventilation verification: Baffles, soffit intake, and ridge exhaust confirmed clear so the attic breathes correctly.
- Verification & warranty: We measure final depth, clean up, and back the work with our 3-year workmanship warranty.
Ice dam season is the moment this all pays off: a cold, dry, balanced attic means snow melts off evenly and water never backs up under your shingles. And on the hottest July day, the upstairs rooms stay comfortable without the AC running nonstop.

Most Tulsa homes should have attic insulation between R-38 and R-60. Oklahoma sits in IECC climate zone 3, where R-38 is the code minimum — but R-49 to R-60 is the practical recommendation because our summers push heat gain hard and our winters bring freeze-thaw cycles. Proof Construction measures your current depth, checks for gaps and compression, and tops up to the right R-value for your home.
It depends on your attic type and budget. Open-cell spray foam seals every crack and gap, which makes it the best air barrier — ideal for stopping Oklahoma's summer heat and winter drafts, but it costs more. Blown-in cellulose or fiberglass is the most cost-effective way to reach R-49+, and it performs great when combined with proper air sealing first. Batt insulation is simple and budget-friendly but leaves more gaps unless installed meticulously. Proof Construction will measure your attic and recommend the option with the best payback.
Yes — ice dams are caused by warm air leaking into the attic and melting snow on the roof, which then refreezes at the cold eaves. Proper attic insulation plus air sealing keeps the roof deck cold, so snow melts evenly instead of forming dammed ice that backs water up under your shingles. Ventilation works alongside insulation to flush heat and moisture out of the attic.
For a typical 1,000-square-foot Tulsa attic, air sealing plus blown-in insulation to R-49 usually runs $1,500–$2,800 installed. Batt insulation is generally $1.00–$1.80 per square foot, blown-in about $1.50–$2.50, and spray foam ranges from $2,800–$5,500 depending on depth and attic size. These are 2026 Tulsa metro market estimates — Proof Construction gives free, itemized quotes after measuring your attic.
Yes — insulation and ventilation work as a team. Insulation slows heat transfer; ventilation removes the heat and moisture that still gets in. Tulsa attics need balanced intake (soffit) and exhaust (ridge or roof) vents, plus baffles so blown-in insulation never blocks the airflow path. Proof Construction checks the whole assembly — insulation, air sealing, and ventilation — before recommending a fix.
