Should you repair, coat or replace a commercial roof?
Good commercial roofing Knoxville TN decisions start with photos. Limited damage gets a repair. A coating only makes sense when the roof is sound and dry underneath. If water has reached the insulation or deck in many places, or the membrane is worn out, we replace it.

Commercial Roofs We Work On
- Churches, including steeples and steep sanctuary roofs reached by boom lift.
- Offices and storefronts with architectural shingle roofs.
- Low-slope and flat sections: pipe boots, flashing and drains.
- Metal roofs on shops, barns and outbuildings.
Flat Roof Repairs
Flat roofs mostly leak where something passes through them: pipes, drains, curbs and walls. On this West Knoxville flat roof, for example, we replaced a failed pipe boot and sealed it into the membrane.
Codes for Commercial Roof Replacement in Knoxville
Inside the City of Knoxville, a registered design professional is required if the building is 5,000 square feet or larger, or over two stories. Smaller jobs still need a permit. Because the rules differ, we tell you up front which applies to your building. City of Knoxville Plans Review. Knox County Codes.
Why Flat Roofs Fail Early Here
Knoxville sees 66.6 nights a year at or below freezing (NOAA normals), with most days warming back up. So water that sits in low spots freezes and thaws again and again, which opens seams and flashing. As a result, keeping drains clear and fixing ponding early adds years to a low-slope roof.
Church and Steeple Work
We repaired this Friendsville church steeple from a boom lift while working around the building’s schedule. Because faith is at the center of our company, we treat church roofs with the care they deserve.
How Commercial Projects Work
- Site visit and inspection with photos.
- Written scope and estimate, noting permit and design-professional requirements.
- Scheduling around your business or services.
- Site protection. Before a single shingle comes off, we shield HVAC units, shrubs and landscaping with the Catch-All system, breathable debris netting that catches shingles and nails before they land, so nothing gets scratched, crushed or buried in debris. Entrances and parking stay clear.
- Installation or repair.
- Cleanup and closeout photos.
All work is completed to Tennessee building code.

Frequently Asked Questions
Do you work on churches?
Yes. We have repaired church steeples and roofs, including work from a boom lift, and we schedule around services and events.
Do you repair flat roofs?
Yes. We repair leaks at pipe boots, drains, curbs and walls on flat and low-slope roofs, and then photograph each repair.
Does my commercial roof replacement need an engineer or architect?
Inside the City of Knoxville, a registered design professional is required if the building is 5,000 square feet or larger, or over two stories. If you are unsure, contact City Plans Review to confirm for your building.
Should I coat my flat roof instead of replacing it?
Only if the existing roof is dry and sound underneath. However, a coating over wet insulation traps the problem. So we inspect first and tell you which makes sense.
Do you offer financing?
Yes. We offer 18 months same-as-cash financing, subject to credit approval, so you can spread out the cost. Ask about it when we give you your written estimate.
Will you protect my landscaping and AC unit?
Yes. Before tear-off we set up the Catch-All system: breathable debris netting plus shields over your A/C unit, shrubs and beds that catch falling shingles and nails. Plants are never left under hot plastic, debris goes out with the dumpster, and we finish with a magnet sweep of the yard before we leave.
