One City, Many Kinds of Attics

Spray Foam Insulation in Oklahoma City has to cover a lot of ground. The city was settled in a single afternoon during the Land Run of April 22, 1889, grew outward for more than a century, and now stretches across roughly 620 square miles, about 377 of them still rural watershed land, according to Wikipedia. Census Reporter shows about 314,000 housing units in the 2024 American Community Survey. Inside that footprint are prewar bungalows near downtown, postwar ranches on the north and south sides, 1970s and 1980s tract homes, brand-new subdivisions on the edges and plenty of acreage with shops and metal buildings.

The heat is the common thread

Whatever the age of the house, the summer is the same. The Will Rogers airport normals listed on Wikipedia show a July average high of 93.1F, about 70 days a year at 90F or above and roughly 10 days at 100F, with an annual mean relative humidity of 64.9 percent. The attic is where that heat piles up. Most OKC homes have their ductwork or air handler up there, so every gap in the ducts and every leak in the ceiling makes the air conditioner work harder.

Older neighborhoods

In homes from the 1940s through the 1960s, we often find a few inches of settled loose fill, open chases around plumbing and old flues, and little or nothing in the walls. The fix is usually to seal the attic floor carefully and blow it to depth, and in some houses to dense-pack the walls. Where the attic is shallow or crowded with ducts, foam on the roof deck may make more sense.

Newer homes

Houses built in the last twenty years usually meet the code minimums of their day, and Oklahoma's current residential code calls for R-30 in ceilings in Climate Zone 3. The Department of Energy recommends more for existing Zone 3 attics. Our most common calls from newer neighborhoods are bonus rooms over garages, kneewalls in second-floor rooms and attics where blown fill was left thin near the eaves.

Storms and roofs

Wikipedia counts about 150 tornadoes within the city limits since 1890 and a severe season that peaks in April and May. Hail and wind mean a lot of roof replacements, and every new roof is a chance to look at the insulation and decking underneath. Get a free estimate

Oklahoma City Questions

Which insulation suits an older Oklahoma City ranch home?

For most postwar ranches with an open attic, careful air sealing plus blown-in cellulose or fiberglass to R-38 or more gives the most for the money. Spray foam makes sense where the attic is shallow or the ducts take up the space.

Should the attic in my OKC home be sealed with spray foam?

If the air handler and most ductwork are in the attic, foaming the roof deck brings them inside the insulated space, which can help a lot in summer. It costs more than blown-in, so we price both when either would work.

Does OG&E offer insulation rebates in Oklahoma City?

OG&E lists an attic insulation rebate for Oklahoma residential customers, with rules on starting and finished depth and professional installation. Check its current page for the amount before work starts.

How soon after a new roof should I check the attic?

Any time after the roof is done. Look for wet or stained insulation, damaged decking and nails that missed the rafters. We check for those on every attic visit.
