Commercial Roofing Repair
A single ponding puddle on a flat commercial roof can hold hundreds of pounds of standing water after one heavy storm. Left in place, that weight stresses the membrane, works into seams, and eventually finds its way into the building below. Small problems like this are exactly why commercial roofs need attention long before a leak reaches the ceiling tiles. At Southern Roofing and Restoration, we focus on catching these issues early and repairing them in a way that extends the service life of the entire system.
What Separates Commercial Repair From Residential Work
Commercial roofing operates on a different scale and uses different materials than a typical house. Flat and low-slope systems dominate warehouses, retail centers, offices, and medical facilities. These roofs rely on membranes, coatings, and drainage design rather than the steep pitch and shingles you find on a home. Because of this, the repair methods, tools, and inspection routines are highly specialized.
A repair on a single-ply membrane, for example, is nothing like patching an asphalt shingle. The team at Southern Roofing and Restoration adjusts its approach to the specific system in place, whether that is TPO, EPDM, modified bitumen, or a built-up roof. Matching the repair to the material keeps the fix compatible with the existing installation and preserves any manufacturer warranty still in effect.
Systems We Repair
Every commercial roof type ages and fails in its own way. Knowing the typical failure points lets us target the repair rather than replace more than needed. We regularly service the following systems:
- TPO and PVC single-ply: seams and flashing are the usual trouble spots, and heat-welded repairs restore a watertight bond.
- EPDM rubber: shrinkage and punctures respond well to patching and adhesive seam work.
- Modified bitumen: blisters, splits, and lifted laps get sealed and reinforced.
- Built-up roofing: alligatoring and gravel displacement are addressed with recoating and localized repair.
- Metal roofing: fastener backout, rust, and open seams are treated to stop water entry.
As a GAF Master Elite contractor, Southern Roofing and Restoration works with products that meet strict manufacturer standards. That certification means the crews follow tested installation practices, which matters when a repair must integrate with the surrounding roof rather than stand apart from it.
Our Inspection and Repair Method
A good repair starts with an accurate diagnosis. Water travels along the underside of a membrane and inside insulation, so the visible stain rarely sits directly under the actual breach. We trace the source rather than treat the symptom. Our inspection covers the field of the roof, the perimeter edges, and every penetration where pipes, vents, and HVAC units break through the surface.
Once we identify the cause, we document the condition with photographs and explain what we found in plain language. From there, the repair proceeds in clear stages:
- Surface preparation: the area is cleaned and dried so new material bonds correctly.
- Membrane or flashing repair: compatible patches, welds, or sealants are applied to match the existing system.
- Drainage correction: drains, scuppers, and tapered insulation are checked to move water off the roof.
- Final verification: the completed repair is inspected and, where appropriate, water tested.
This methodical sequence prevents the common mistake of sealing over a wet substrate, which traps moisture and invites the same failure to return within a season.
Technical Details That Matter
Commercial repair quality often comes down to specifics most building owners never see. Seam welds on thermoplastic membranes need the correct temperature and pressure to fuse fully, and a probe test confirms the bond. Flashing height at parapet walls and curbs must extend far enough to keep wind-driven rain out. Fastener patterns and plate spacing influence how a repair holds up under uplift during storms.
We also pay close attention to compatibility. A sealant intended for EPDM will not perform on TPO, and mixing incompatible products is a frequent reason repairs fail early. By respecting these technical requirements, Southern Roofing and Restoration produces repairs that blend into the existing roof and carry their share of the load.
