Spray Foam Insulation Services › Cathedral Ceiling Spray Foam Insulation
Cathedral Ceiling Spray Foam Insulation in Tulsa, OK
Cathedral ceiling spray foam fills the rafter cavities of a sloped ceiling that has no attic space above it — the roof deck is the ceiling structure. Standard fiberglass batts in these cavities don't fill the space completely and create condensation problems at the cold side of the assembly. Closed-cell foam applied directly to the underside of the roof sheathing solves both the air sealing and insulation requirement in a cavity that's too shallow for anything else to work properly.

When to Call
When You Need Cathedral Ceiling Spray Foam Insulation
- A 1970s Tulsa ranch home has a cathedral section that stains the drywall with moisture every winter
- Your roofer found deteriorated sheathing on a cathedral section caused by years of condensation and poor insulation
- An architect-designed home in Maple Ridge has shallow rafters that won't accommodate code-depth fiberglass
- You're re-roofing a section with a cathedral ceiling and want to address the insulation while the deck is exposed
How It Works
Our Process for Cathedral Ceiling Spray Foam Insulation
- 1
Rafter Depth Measurement
We confirm available cavity depth and roof assembly type before specifying foam thickness and required R-value approach.
- 2
Access Planning
Cathedral sections are typically sprayed from below through the interior — we confirm access and prep the finished space.
- 3
Closed-Cell Application
Foam is applied in lifts against the roof sheathing, filling the cavity while keeping required ventilation clearances if applicable.
- 4
Interior Protection and Cleanup
All furniture, flooring, and adjacent surfaces are masked before application and uncovered after foam has cured.
Tulsa Context
Why this matters in Tulsa
Tulsa's temperature swings create real condensation risk in poorly insulated cathedral ceilings — warm interior air hitting a cold roof deck is how sheathing rots from the inside out over time.
Straight Talk
About pricing & scope
Rafter depth and whether the assembly is vented or unvented changes both the foam specification and the cost significantly. Shallow cathedral cavities sometimes require spray foam plus exterior rigid foam to hit code R-values.
