Brief History / Office Personnel Profiles
Roofing Services Co., Inc. was started by Gary Nasalroad in 1985 while attending Oklahoma State University and after serving in the U.S. Army. At that time we did both Residential and Commercial roofing in the Stillwater area only, Stillwater is still our main distribution center, but now we service all of Oklahoma and several neighboring states.
In the early 1990’s we began installing guttering, vinyl siding, replacement windows, and began doing business as Roofing Services Co., Inc. dba RSI (Roofing, Siding, and Insulated Windows) to better represent our changing company. In 2000, we added metal patio covers, carports, enclosed sun-rooms, screened room enclosures as well as miscellaneous carpentry work.
On most days our trucks and crews can be seen throughout Oklahoma and the central U.S. doing both residential and commercial projects. We have completed roofing projects in Washington state, Galveston, TX and as far south as Georgia. Our Commercial division does both new and re-roofing projects and we specialize in the the installation of EPDM, TPO and PVC membrane systems and are certified by several manufacturers to give labor and material warranties from 15 to 30 years depending on system type. Send us your blue prints and/or I-Sq project number for a complete take-off and quote.
Our residential crews install all types of asphalt roofing, wood shakes, tile, slate, and metal roofing. The metal roofing crews install R-panels, standing seam, and stone-coated metal shingles.
