Mobley Brothers Roofing & Renovation handles commercial roofing across Knoxville and East Tennessee from our Knoxville office in Hardin Valley. Most of our Knoxville commercial work comes the old-fashioned way: a property owner sees our crews on a building down the road and calls. Churches, schools, and commercial buildings make up that work, and a dedicated commercial foreman looks at every job.
His first question is the same one we ask on houses: can this roof be repaired? If it can, we repair it. If it needs a new system, we tell you which one and why.
A commercial roofing contractor Knoxville property owners already know
Commercial roofing is a relationship business. Owners and managers rarely hire from a web search alone; they want to know who did the building next door and whether that company answered the phone the second time. That is how most of our commercial work in Knoxville has grown. When we fix a leak on one building or put a new roof on another, the calls that follow often come from people who saw the work.
Mike Mobley runs the Knoxville office, and his commercial foreman handles commercial jobs from the first walk through the finished job. Mike goes out with him on some of them. You deal with the people who will be responsible for the roof, not a sales rep who hands you off.

Commercial roofing services we provide in Knoxville
We install, repair, replace, and maintain commercial roofs. What goes on a building starts with how it was designed, what is on it now, and how the owner plans to use it.

Single-ply membranes: TPO, EPDM, and PVC
On most low-slope commercial roofs, the answer is a single-ply membrane, and most of the time that means TPO. We also install EPDM and PVC. The right one depends on the building, the existing roof, and what is on top of it, such as rooftop units.
Retrofits over ribbed metal roofs
Many older commercial and industrial buildings around East Tennessee have ribbed metal roofs. Rather than tearing them off, we can install rib filler to create a flat surface and go back over the metal with a TPO or EPDM membrane.
Coatings for roofs with life left
Coating an existing TPO or EPDM roof that is still sound can buy it additional years and make a warranty possible, for less disruption than a replacement. We have coated commercial roofs in both Knoxville and Middle Tennessee. Not every roof is a candidate, and we will tell you if yours is not.
Commercial metal and mixed roofs
We install commercial standing seam metal, and we work on the mixed roofs common on churches and larger buildings, where flat sections, shingles, and metal all meet.
| Option | Tends to fit | What we check first |
|---|---|---|
| TPO membrane | Most low-slope commercial roofs, new or replacement | Existing layers, drainage, rooftop units |
| EPDM membrane | Low-slope roofs where EPDM is specified or already in place | Seams, flashing at walls and curbs |
| PVC membrane | Low-slope roofs where the owner or designer specifies PVC | Building use and existing system |
| Rib filler and membrane over metal | Ribbed metal roofs that leak but are structurally sound | Condition of the metal and fasteners |
| Roof coating | Existing TPO or EPDM roofs that are still sound | Whether the roof is dry and intact enough to coat |
| Standing seam metal | Pitched commercial roofs and additions | Roof pitch, design, and flashing details |
Commercial roof assessments before any recommendation
A commercial roof usually gives warning before it fails. Leaks start showing up around rooftop air conditioning units and other penetrations, then they come more often. By the time a tenant is putting buckets out, there is typically a pattern.
When our commercial foreman walks a roof, he is deciding among three honest answers. It can be repaired and will be fine. It can be kept going for a while with targeted repairs while you plan and budget. Or it needs a new roof, in which case we quote the system that fits the building without overbuilding it. You get photos of what he found and a written proposal, so you can take it to your partners, your board, or your landlord.

Maintenance for commercial roofs
Most commercial roofs do not fail all at once; they get worn down by small problems nobody looked at. Debris collects near drains and against curbs, flashing works loose, and a small leak around a unit runs for months above a drop ceiling.
We have customers who call us for repairs year after year, and that history lets us tell them when repairs have stopped making sense. One commercial client had us handle repairs for three or four years before we told the manager it was time to choose between a new roof and a coating. That kind of plain answer is the point of a maintenance relationship.
A simple habit helps any building: after storms and again each fall, have someone confirm that drains are clear and that leaves and debris are not piled against curbs or rooftop units. Debris holds water against the membrane and the flashing, and that is where small leaks start. When you would rather not send your own people up, call us and we will look at it, photograph anything that needs attention, and tell you what can wait. If you own the building but lease it out, we can work with you or your property manager directly.

Retail centers, churches, and mixed-use buildings around Farragut and West Knoxville
The Farragut area, just a few miles from our Hardin Valley office, has a lot of large commercial retail space, and the corridors out toward West Knoxville and Cedar Bluff are close to home for us too. Those are exactly the kinds of buildings our commercial crews work on: low-slope roofs with rooftop equipment, long runs of flashing, and owners who need the business to keep running while the roof is worked on.
Churches are their own category. We consider them commercial work, and many have mixed roofing, with flat sections, shingled areas, and sometimes metal, all on one building. Getting the transitions between those roofs right is often where a leak is solved.
Recent commercial and low-slope work in East Tennessee
Recent jobs from the Knoxville office include a flat roof leak repair in Knoxville, a commercial roof repair in Harriman, a flat roof repair in Louisville, an estimate for a flat roof leak repair in Alcoa, and a commercial TPO roof replacement in Loudon. The commercial side of that work runs alongside our residential crews.

Manufacturer standing and the people behind it
GAF lists our Knoxville business as a GAF GoldElite Commercial contractor, and we are also a GAF Master Elite residential contractor. We hold Tennessee contractor license 59116, we are fully licensed and insured, and both of our offices are BBB Accredited with an A+ rating.
Credentials open the door, but commercial customers keep calling because of how the job is run: a clear scope, crews that clean up each day, and a family company that has been on East Tennessee roofs since 2007 and plans to be here for the next repair.

Questions property owners ask about commercial roofing
Straight answers, the way we would give them on your driveway. If yours is not here, call the office and ask.
More questions we get askedCan you keep my commercial roof going a few more years before I replace it?
Often, yes. If the roof is sound overall, targeted repairs or a coating on an existing TPO or EPDM roof can carry it while you budget for replacement. Our commercial foreman will tell you honestly whether that is realistic. If the roof is past that point, he will say so and show you why, because patching a roof that needs replacing just moves the expense around.
Who decides which roof system goes on my building?
It starts with the building itself: how it was designed, what is on it now, and what the owner needs from it. Our commercial foreman evaluates each job and recommends a system, and Mike Mobley sometimes goes out with him. If an architect specified a system, we start there. Most of the time the recommendation is a TPO membrane, but EPDM, PVC, metal, and coatings each have their place.
Can you put a new roof over a ribbed metal building?
Yes, in many cases. If the metal structure is sound, we can install rib filler between the ribs to create a flat surface and then cover it with a TPO or EPDM membrane. That avoids tearing off the old metal and can solve chronic leaks at fasteners and seams. We will check the condition of the metal first to make sure it can carry the new system.
Do you work on church roofs in Knoxville?
Yes. We treat churches as commercial work, and they are a large part of what our Knoxville office does. Many church buildings have a mix of flat roofs, shingled sections, and metal, often added at different times, so the flashing where those roofs meet deserves as much attention as the roofs themselves. We also work on schools and other commercial buildings.
Do you work with property managers and building owners who lease?
Yes. Property managers are some of our most regular customers; one has called us for roof repair at least a dozen times. We can report to the owner, the manager, or both, with photos and a written proposal for each roof. When a leased building's roof is nearing the end, we give the owner the information needed to plan rather than a surprise.
Do you handle commercial roofing in Farragut and the rest of Knox County?
Yes. Our Knoxville office is in Hardin Valley, a few miles from Farragut, which has a lot of large commercial retail space. We also cover Oak Ridge, Karns, Powell, Clinton, Lenoir City, Maryville, Louisville, Loudon, and the rest of our East Tennessee service area for commercial work.
Can you respond to a commercial roof leak at night?
Someone will answer or call you back quickly, day or night. What we can do that night depends on the weather; nobody can work safely on a roof in lightning or high wind. We will talk you through protecting inventory and equipment, then get a crew there as soon as it is safe to make a temporary or permanent repair.
