Flat Roof Repair
Diagnose & Fix Commercial Roof Leaks
Flat and low-slope commercial roofs leak in predictable places — seams, penetrations, flashing, and drains. We find the source and repair it correctly.
Flat and low-slope commercial roofs — whether TPO, EPDM, modified bitumen, built-up, or metal — share common leak points. Finding the actual source of a leak requires getting on the roof and tracing it, because water often travels before it appears inside.
Artisan Enterprise LLC repairs flat commercial roofs throughout Martinsville and Southern Virginia, and we'll tell you honestly whether a repair, a restoration, or a replacement is the right call.
Flat Roof Types We Repair
We repair the most common low-slope commercial roof systems:
- TPO single-ply membrane
- EPDM rubber membrane
- Modified bitumen
- Built-up roofing (BUR)
- Low-slope and standing-seam metal
- Coated and restored roofs
Common Causes of Flat Roof Leaks
Flat commercial roofs most often leak because of:
- Failed seams (under-welded, aged, or lifting)
- Flashing and penetration detail failures (vents, pipes, HVAC curbs)
- Clogged or overwhelmed drains and scuppers
- Ponding water that degrades the membrane over time
- Punctures from foot traffic or mechanical work
- Membrane shrinkage pulling at flashings
Repair Approaches
Repairs are matched to the problem:
- Re-seaming or re-welding failed seams
- Re-flashing penetrations and edges
- Patching punctures and blisters with compatible materials
- Clearing and improving drainage
- Treating localized wet insulation
- Sealing fasteners and metal details
When to Repair vs. Replace
Targeted repairs are appropriate when leaks are localized and the membrane is otherwise sound. When seams are failing across the roof, insulation is widely saturated, or the membrane is at the end of its life, replacement — or in some cases a coating restoration — is the better investment. An inspection tells us which applies.
Ponding Water on Flat Roofs
Ponding water — water that remains on the roof 48 hours after rain — degrades membranes, stresses seams, and accelerates aging. Some coating systems tolerate ponding better than others, but the underlying drainage or slope issue should be addressed. We evaluate drainage as part of every flat-roof inspection.
Maintenance to Prevent Repairs
Most flat-roof leaks are preventable with twice-yearly inspections, keeping drains and scuppers clear, limiting foot traffic, and promptly repairing small seam and flashing issues before they let water in.
