A flat roof rarely fails all at once. It usually starts with one opened seam, one cracked boot around a vent pipe, or one low spot where water sits for days after a storm. Catching the problem while damage is localized can make repair more manageable. Glick Roofing Systems provides flat roof repair in Clarksville, TN for commercial buildings. A lasting repair starts with identifying the cause of a leak, rather than only the spot where water appears inside. To schedule an inspection, call 800-821-0205.
Defects We Repair on Flat Roofs
Clarksville’s weather is tough on low-slope roofs. Hot summers, storms, and winter temperature changes put stress on membranes and roof details. Common defects that may require repair include:
- Open or weak seams. Movement, aging bonding materials, or inadequate installation can allow membrane laps to separate.
- Punctures and tears. Dropped tools, HVAC service work, sharp debris, and storm impacts can damage the membrane.
- Blisters and ridges. Trapped air or moisture can raise portions of the roofing or coating. The appropriate response depends on the system and the condition of the raised area.
- Shrinkage at the edges. Aging EPDM can pull at walls, curbs, seams, and perimeter details.
- Failed flashing. Pipe boots, pitch pans, curbs, and wall terminations can crack, separate, or come loose.
- Cracked or worn coatings. Chalking, peeling, and exposed underlying material can indicate a need for maintenance or repair.
- Surface cracking on built-up and modified bitumen roofs. Aging asphalt-based surfaces can develop cracks and splits.
Repair Methods Matched to Your Roof System
A repair only holds when the materials and preparation suit the existing roof. An incompatible patch can fail or complicate later repairs. The following methods illustrate how repair materials are matched to the roofing system:
| Roof System | Compatible Repair Method |
|---|---|
| TPO | A compatible TPO patch hot-air welded to a properly cleaned and prepared surface, after confirming the existing membrane can accept a sound weld. |
| PVC | A compatible PVC patch heat-welded after preparation and evaluation of the existing membrane’s weldability. |
| EPDM | Manufacturer-approved primer, EPDM repair membrane, tape, or flashing accessories suited to the defect. Cured EPDM is not heat-welded. |
| Modified Bitumen | A compatible modified bitumen patch installed using a method approved for the existing system, with surfacing restored as required. |
| Built-Up Roofing (BUR) | Compatible bitumen and reinforcing plies, followed by restoration of the specified protective surfacing. |
| Silicone or Acrylic Coating | Repair underlying defects, evaluate coating compatibility, prepare the surface, and apply the specified primer and repair coating according to manufacturer requirements. |
An incompatible product, such as an unapproved asphalt mastic on a single-ply membrane, may not provide a durable bond and can complicate future repairs. For another Middle Tennessee location, see our page on commercial flat roof repair in Brentwood, TN.
Drainage and Flashing Checks
Leaks frequently develop around seams, drains, flashing, and roof penetrations, although damage in the membrane field can also cause leaks. These areas deserve attention when evaluating a repair.
Drainage. Drains, strainers, scuppers, gutters, and downspouts should be checked for debris and damage. Water remaining roughly 48 hours after rainfall is worth investigating, particularly when the condition recurs. Roof design, weather conditions, and applicable system requirements also matter.
The evaluation should consider whether crickets and tapered insulation direct water toward outlets. A patch in an area with recurring ponding may leave the underlying drainage problem unresolved, so drainage corrections may need to be included in the repair scope.
Flashing. Perimeter edge metal, termination bars, counterflashing, HVAC curb flashing, pipe boots, and pitch pans should be checked for loose connections, open laps, and deteriorated seals. Water entering through walls or coping above the flashing can also appear to be a roof leak.
Limits of a Localized Repair
A patch isn’t always the right answer. A localized repair works best when damage is limited and the surrounding materials remain suitable. A broader scope may be needed in these situations:
- The insulation underneath is wet. A surface patch does not address saturated insulation. Infrared surveys may help identify suspected wet areas under suitable conditions, while targeted core samples or other methods can help confirm findings. Wet materials need appropriate removal and replacement.
- Seams are failing across the roof. Widespread failures require an assessment of installation, membrane condition, and whether repairs remain practical.
- The deck is damaged. Soft areas, rust-through, or rotted wood require investigation and suitable deck repairs. Structural concerns may require an engineer.
- The roof has needed many repairs. Recurring leaks or extensive patches warrant comparison of continued repairs with restoration or replacement.
- A warranty is in force. The written warranty may require approved repair materials, authorized installers, or notification before work. These requirements should be reviewed before repairs begin.
When a localized repair is unlikely to provide a durable result, the findings should explain why and identify appropriate alternatives. Property managers comparing commercial roofing companies in Clarksville, TN should expect recommendations supported by the roof’s condition.
How Completed Work Is Checked
A repair needs checks appropriate to its materials and scope. Depending on the roof system, completion checks may include:
- Checking cooled TPO and PVC patch welds using the manufacturer’s specified inspection method to identify gaps or weak areas.
- Inspecting repaired flashing, terminations, and patch edges for proper installation.
- Using controlled water testing where suitable for the assembly and building conditions.
- Checking that repairs and debris do not obstruct drainage.
- Photographing repaired areas and recording the materials and locations involved.
- Arranging follow-up observation after rainfall when needed to assess a recurring or uncertain leak.
Confirm the checks and documentation included in the repair scope. Routine inspections in spring and fall, plus checks after major storms, can help identify new defects before they spread.

Frequently Asked Questions
How long does a flat roof repair last?
A properly installed repair using compatible materials can provide lasting performance, but its service life depends on the roof’s condition, preparation, installation quality, drainage, and weather exposure. An unresolved leak source or unsuitable surrounding membrane can shorten repair life.
Is it better to repair or replace a flat roof?
Repair often makes sense when damage is localized and the surrounding assembly is sound. Widespread moisture, extensive failures, deck damage, or a deteriorated membrane may require a broader solution. Restoration is only suitable when the existing roof meets the proposed system’s requirements.
How do you find a leak on a flat roof?
An investigation connects interior leak locations with accessible roof conditions, including seams, drains, flashing, and penetrations. Water can travel within the assembly before appearing inside. Where visual findings are inconclusive, suitable additional investigation may include controlled water testing, moisture surveys, or inspection openings. Infrared findings indicate suspected moisture patterns rather than necessarily identifying the exact entry point.
Can a flat roof be repaired in the rain?
Some temporary repair products permit use in wet conditions, but safe access and product requirements determine what is possible. Many permanent repairs, including heat-welded patches and primed tape repairs, require clean, dry surfaces. Temporary work may need follow-up once conditions improve.
What causes water to pond on a flat roof?
Blocked drains, deck deflection, compressed insulation, and inadequate slope around curbs or between outlets can contribute to ponding. The appropriate correction depends on the cause and may involve drainage improvements or changes to the roof assembly.
Does insurance cover flat roof repair?
Coverage depends on the policy, cause of damage, exclusions, and the insurer’s assessment. Dated photographs, inspection findings, and repair records can support a claim, but they do not guarantee coverage. Ask your insurer what documentation it requires.
