Harper's Insulation is a locally-based contractor specializing in insulation installation, roof deck preparation, and attic ventilation work tied to roofing projects across Oklahoma City and surrounding areas. The business handles both new construction and retrofit jobs, with a focus on materials and techniques that directly affect roof performance and energy efficiency in the city's climate.
Harper's works primarily on the systems beneath and around roofing rather than shingles or structural repairs. Their core services include blown-in cellulose and fiberglass insulation, rigid foam board installation, attic air sealing, soffit and ridge vent installation, and roof deck preparation before new roofing material goes down. Because inadequate attic ventilation and insulation directly shorten roof life in Oklahoma's heat cycles, roofing contractors often recommend this work as a package with new roof installation or replacement.
The company operates as a subcontractor for larger roofing firms and also takes direct residential clients. Jobs range from adding insulation to older attics (common in Oklahoma City's older neighborhoods near Uptown and Midtown) to preparing new construction attics for shingles or metal roofing systems.
Blown-in cellulose typically runs $1.50 to $2.50 per square foot installed, depending on R-value (the company commonly works in R-38 to R-60 range for Oklahoma attics). Fiberglass batts cost slightly less per square foot but take longer to install and leave more thermal bridging at joists. Rigid foam board for roof decks runs $0.80 to $1.40 per square foot plus labor. Air sealing packages, which address gaps around electrical penetrations and rim joists, start around $400 for a typical 1,500-square-foot attic and scale upward with complexity.
Harper's provides free estimates and typically inspects the existing attic to determine whether prior insulation is compacted (which reduces R-value significantly in Oklahoma's older homes) and where air leaks occur. Most estimates are provided within 2 to 3 business days. Pricing varies with material choice and existing conditions; confirm current rates directly, as material costs shift seasonally.
Harper's differs from full-service roofing firms like those in the OKC metro that handle shingles, gutters, and structural work. Companies such as Apex Roofing and similar mid-size contractors sometimes bundle insulation work into larger roof projects, but they charge roofing-labor rates for the insulation portion. Using Harper's as a standalone or paired contractor typically costs less because they specialize in insulation labor and buy materials in volume.
Choose Harper's if your roof replacement includes attic work or if you are addressing energy efficiency independently. Choose a full-service roofing contractor if your roof also needs shingles, flashing, or structural repairs and you prefer a single point of contact. Choose a general home insulation contractor (some offer both wall and attic work) if your project spans multiple areas of the house beyond the attic.
Harper's is a fit for homeowners in Oklahoma City with older attics (pre-1990s construction often has minimal or degraded insulation), those planning new roof installation, and anyone seeing energy bills spike during the city's summer cooling season. The work is especially relevant in neighborhoods like Edgemere Park and older sections of Nichols Hills, where original insulation has settled.
Harper's does not do roofing material installation, so if you need shingles replaced, you need a separate roofing contractor. It is not the right choice for wall cavity insulation (a different skill and material set) or spray foam work (which requires specialized equipment Harper's may not operate). Read the estimate carefully to confirm what is included.
Harper's sends a technician to the home for the estimate, typically scheduling within a week. The visit includes an attic inspection: the tech checks existing insulation type and depth, looks for moisture, mold, or roof leaks, identifies air leaks around vents and electrical lines, and assesses ventilation adequacy. This inspection usually takes 30 to 45 minutes. The estimate is provided in writing and includes material type, square footage, R-value, labor hours, and timeline (most jobs complete in one to three days depending on size).
Once you approve, Harper's schedules installation. Work typically runs during business hours; attic access and ventilation mean the crew will need clear pathways and may recommend temporary relocation of stored items. A typical 1,500-square-foot attic insulation job takes one to two days.
Harper's operates Monday through Friday, 7 a.m. to 4:30 p.m., with occasional Saturday appointments available during peak season (March through October). The company does not maintain a retail location; all work is on-site. Call or request an estimate online through their website or phone number, which you can confirm by searching "Harper's Insulation Oklahoma City" in local directories.
Parking is not an issue since trucks park at the home being serviced. Most residential addresses in Oklahoma City proper fall within their service area; confirm this during the initial call if you are on the city fringe.
Harper's fills a specific gap in Oklahoma City's roofing ecosystem by handling the attic and ventilation work that many full-service roofers bundle at inflated labor rates. For energy efficiency and roof longevity, this work matters as much as the shingles themselves.
