Commercial Roofing in Johnson City, TN
Commercial Roofing for Johnson City Medical, University, Office, Retail and Manufacturing Buildings
Commercial Roofing for Johnson City and Washington County
McGuire Roofing serves Johnson City from our Knoxville office, roughly an hour and forty-five minutes northeast on I-40, I-81 and I-26. Johnson City is the largest of the three Tri-Cities, with 71,046 residents in the 2020 Census, and its commercial buildings are a different mix from Kingsport or Bristol: the economy here leans on healthcare, higher education and services, with manufacturing alongside.
That shows on the rooftops. The Johnson City Medical Center campus, East Tennessee State University, the Mountain Home VA campus next door, call centers and office buildings, and the clinics and medical office buildings that serve a large regional patient base all carry big low-slope roofs with heavy rooftop equipment. Downtown Johnson City has older brick storefronts with flat roofs behind parapets, many with new upper-floor apartments, and retail and restaurant buildings stretch along the commercial corridors toward I-26.

What Upper East Tennessee Weather Does to Johnson City Roofs
Johnson City sits higher than Knoxville, at the foot of the mountains along the North Carolina line, so winters bring more snow, ice and freeze-thaw cycles than the valley to the southwest. Thaw water that refreezes at drains and scuppers backs up on flat roofs, and repeated cycles open up tired seams and base flashings. Summer brings humidity and heavy afternoon rain. On hospital and campus buildings the biggest risk is usually around the rooftop equipment: curbs, pipe penetrations and condensate lines where water finds a way in.
Johnson City at a Glance for Commercial Building Owners
Johnson City is in Washington County and had 71,046 residents in the 2020 Census. A few things that shape its commercial roofs:
- Washington County EDC lists East Tennessee State University (about 3,541 employees), Johnson City Medical Center (about 2,000), Advanced Call Center Technologies (about 2,000) and American Water Heater Company (about 1,097) among the county’s top employers in Johnson City.
- Washington County EDC also lists the Veterans Affairs Medical Center at Mountain Home, Ballad Health and State of Franklin Healthcare among the area’s major employers.
- The City of Johnson City and ETSU are planning a 60-acre Innovation Park west of Johnson City Medical Center and the VA Medical Center, bounded by West Market Street.
- Johnson City sits on I-26 with access to I-81, and Washington County businesses can use Foreign Trade Zone 204 in the Tri-Cities.
In Johnson City the fit is usually white single-ply (TPO or PVC) on medical and office buildings, modified bitumen or PVC on older downtown flat roofs, and metal repair or restoration on plant and warehouse buildings.
Roofing Occupied Hospitals, Campus Buildings and Offices
Medical and university buildings cannot simply close for a re-roof. On those jobs we plan staging, noise, odor and crane lifts around patients, students and staff, protect air intakes, and keep each section watertight at the end of the day. For low-slope replacement we most often look at Johns Manville TPO or PVC over new tapered insulation; PVC is a good fit where kitchen or lab exhaust reaches the roof. Downtown masonry buildings usually need parapet, coping and through-wall flashing work as much as new membrane.
Commercial Roofing Systems We Install in Johnson City
Johns Manville is our main commercial manufacturer, including JM PVC, EPDM, TPO and modified bitumen. We are Duro-Last certified, mainly for prefabricated PVC, and GAF commercial certified as a third option. We recommend the system that fits the building, its use and its budget.
TPO
Heat-welded, reflective single-ply membrane for offices, retail and warehouses with large flat roofs.
PVC
PVC membranes, including Duro-Last prefabricated systems, for restaurants and roofs with grease exhaust or heavy rooftop equipment.
EPDM
Durable rubber membrane, installed new or repaired on the many existing EPDM roofs across the region.
Modified Bitumen
Multi-ply asphalt-based roofing for older downtown buildings and roofs with regular foot traffic.
Commercial Metal
R-panel and standing seam metal roofs for warehouses, shops, churches and mixed-use buildings.
Roof Coatings
Restoration coatings that can extend the life of a qualifying roof without a full tear-off.
Commercial Roof Repair, Replacement and Restoration
- Inspections and leak repair – We find the source, repair membrane, flashing, curbs and penetrations, and send photos of the work.
- Replacement – Full tear-off or, where the existing roof and local codes allow, a recover system. We pull the permits the local jurisdiction requires.
- Restoration – Coatings for roofs that are still sound underneath, after an inspection confirms they are good candidates.
- Drainage and gutters – Drains, scuppers and commercial gutters sized for heavy rain.
- Maintenance programs – Scheduled inspections, drain and debris clearing, minor repairs and photo reports. See our commercial roof maintenance programs.
- Safety – Work is planned around occupants and customers, following our roofing safety practices.

Can you re-roof a medical office or clinic while it stays open?
Yes. We phase the work, schedule noisy tasks around patient hours where possible, protect air intakes and keep the building watertight at the end of every work day.
Do you work on older downtown buildings with parapet walls?
Yes. We repair and replace flat roofs on masonry buildings, including coping, parapet flashing and drainage, which is where many downtown leaks start.
Is there a separate page for Kingsport and Bristol?
Yes. Johnson City, Kingsport and Bristol each have their own page, and our Tri-Cities page covers the wider region.
Can my existing commercial roof be coated instead of replaced?
Sometimes. A coating can work when the roof is still sound and dry underneath. We inspect the roof first and tell you whether restoration or replacement makes more sense.

Yes. Our phone is answered 24/7 at (865) 338-7663. After a storm we help secure the roof with temporary repairs or tarping when it is safe, then plan the permanent repair.
