Commercial & Multifamily Roofing and Exterior Services
SA Metro Roofing & Sheetmetal, LLC provides roofing, repairs, and exterior services for apartment communities, multifamily properties, and commercial buildings throughout the San Antonio area. We work directly with property owners and property managers on everything from an isolated leak to a property-wide roof replacement.
When a leak keeps coming back, there is a reason. Repairs layered over old repairs, fasteners covered with sealant, and pipe flashings patched instead of replaced tend to fail again. We find the source of the problem, explain what we find, and do the work with a durable, long-term fix in mind.
Commercially insured for work above 30 feet. We handle roofing, sheet metal, gutters, flashing, and related exterior work, from documented inspections to repairs, replacements, and preventative maintenance. Property managers and owners can contact us directly to discuss a property and request a proposal.
The problems we find
Recurring leaks rarely start as a mystery. On multifamily and commercial roofs we see the same failure points again and again: worn pipe flashings, fasteners left open to the weather, sealants baked off by the sun, weak transitions, gutters that no longer carry water where it belongs, and storm damage that got a quick patch instead of a lasting repair.
Exposed fasteners
Popped or rusted nails left open, or sealed over with caulk that will not hold for long.
Recurring leak paths
Bulges, soft areas, and water paths that keep returning after short-term patches.
Open penetrations and missing caps
Flap up, open duct, missing cap. Water and debris have a straight path into the building.
Punctured vent flanges
Weathered plastic vents crack and puncture at the flange. This unit shows a hole and failed sealant at the base.
Larger punctured vent flange
Same failure pattern on a larger ~6 in. plastic vent: punctured flange, exposed rusted nails, cracked plastic, and caulk that failed off.
Gutters and downspouts
Runs off the wall, crushed sections, and drainage that dumps water onto walks and entries.
Deteriorated vents
Plastic vents that snap off, brittle caulk that falls away, and flanges that no longer seal.
Dryer vents, mesh left in
Mesh traps lint and is a fire hazard. A proper damper opens with dryer airflow.
Plastic gooseneck with brittle caulk that fell off, rusted nails on the flange.
Pipe boots that last
Plumbing pipe penetrations are a notorious leak point. Plastic boots crack, membranes dry out, and flange nails rust. Replacing a failed plastic boot with another plastic boot usually just resets the clock. Our preferred detail is the GAF Master Flow Pivot Pipe Boot: an all-metal exterior that helps avoid seals, gaskets, and collars that degrade when left exposed.

Prep before the Pivot
Proper prep (deck protection and ice and water shield around the pipe) is part of the job, not optional.
Our inspection process
We walk the roof systematically, note deficiencies and likely water paths, photograph what we find, and give you clear recommendations specific to your buildings that you can share with ownership.
Systematic walk
Penetrations, transitions, valleys, edges, gutters, and storm-exposed slopes get reviewed on the roof.
Deficiencies and water paths
We connect what we see to where water is likely traveling, so the repair targets the source.
Photo documentation
Findings are documented so property managers can see the condition and the recommended plan.

You work directly with us
We inspect, diagnose, supply, and perform the work ourselves, so the team that finds the problem is the same team that fixes it. You have one company to call from the first walk to the finished job.
We do the work
Inspection findings lead to our crews performing the repair or replacement, with the details we recommended.
Accountability for installation
If something needs follow-up, you call the company that installed it.
Clear line of responsibility
Property managers get one point of contact for the plan, the schedule, and the finished work.
Materials and workmanship
Commercial roofs fail at the details. We specify materials that help protect penetrations and drainage, then install them so the work can last.
GAF Master Flow Pivot Pipe Boot
All-metal exterior that helps avoid seals, gaskets, and collars that degrade when left exposed. Available in roof-blend colors. See Pipe boots that last for why we prefer it on commercial roofs.
Vents built to stay
Galvanized metal gooseneck and static vents with durable finish. We avoid thin plastic flanges and temporary caulk as the only seal.
Gutters and sheet metal standards
Runs sized for the building, secured downspouts, and flashing details that move water off walls, walks, and entries.
Multifamily and commercial experience
Commercially insured for work above 30 feet. That includes three-story and taller multifamily roofs where access and safety matter. Apartment communities and multi-building properties are part of how we operate.
Services for property managers and owners
Roofing, sheet metal, gutters, and related exterior work for multifamily and commercial properties. Every service below is work our own team performs.
Inspections & leak investigation
Documented roof walks with photos, findings, and clear recommendations. Recurring leaks traced to the entry point before another patch goes on the work order.

Hail inspections & claim documentation
Documented storm inspections and roofing documentation for managers and owners. The insurance company decides coverage.
Property-wide solutions
Multi-building properties rarely need everything at once. We evaluate condition across the roofs, then help prioritize by urgency, active leaks, and longer-term needs so capital work lines up with what the property actually requires.
Evaluate the whole site
Walk buildings together so shared patterns, weak materials, and storm exposure are clear.
Prioritize by condition
Active water intrusion and failed penetrations come first. Planned replacements follow the documented condition.
Plan the longer term
Preventative maintenance and phased work help the property avoid repeat emergency repairs.
Gutter and downspout repairs
When runs pull off the wall or get crushed at a door, we replace the damaged sections and secure them so water stays in the system.
Why property managers work with us
Property managers need more than a number on a bid. They need clear communication, documentation, and consistent workmanship.
Communication
Findings explained in plain language, with photos you can share with ownership, and scheduling coordinated with your office.
Documentation
Inspection records and repair photos that support the work order and the finished job.
Consistency
The same standards and the same team on every building.
Taller buildings
