Commercial Roofing for Property Owners & Managers
Liberty Roofing Company services low-slope and flat commercial roofs across Baldwin and Mobile County — repair, replacement, and maintenance programs built around your building's operating hours, your tenants, and the documentation your ownership group or insurer needs to see.

BBB A+ Accredited since 1988
A different buyer, a different job
Built around how a commercial roof actually gets managed
A homeowner deciding on a re-roof and a property manager deciding on a commercial roof are solving different problems. A commercial roof usually means a low-slope or flat membrane system, a building that stays occupied and operating during the work, and a decision that has to be documented for an ownership group, a board, or an insurance carrier — not just weighed over dinner.
Liberty Roofing Company is a licensed and insured Alabama roofing contractor with over 30 years on the Gulf Coast, and we service commercial and flat roofing systems across Baldwin and Mobile County the way this buyer actually needs it done — scheduled around your building, documented for your records, and assessed honestly on repair-versus-replace before a recommendation is made.
Tell us the building, the square footage, and what it is doing. We will come assess it.
Low-slope & flat roof systems
The systems we install and service
Liberty installs and services EPDM, modified bitumen, and built-up (BUR) roofing systems for commercial buildings and flat residential sections across Baldwin and Mobile County.
You'll also hear TPO — a single-ply thermoplastic membrane — mentioned alongside these when people talk about low-slope commercial roofing. It's a real, widely used system; it just isn't one we're claiming here. If your building already has a TPO roof, or you're weighing it as an option, bring it up during your assessment and we'll talk through what actually fits your building rather than steering you toward what we install.

- Commercial and flat residential applications
The honest call
Repair or replace? It depends on the substrate.
A low-slope roof doesn't fail the way a shingle roof does — there's no single storm event, usually just a slow accumulation of failed seams, worn membrane, and ponding water. That makes repair-versus-replace a genuine judgment call, not a formality.
When repair makes sense
Isolated seam failures, a single damaged section, or a roof that's otherwise sound but losing at a specific point. The substrate underneath is still dry and stable.
When replacement makes sense
Widespread membrane failure, a substrate that's wet or has taken on water over time, or a roof at or past the end of its system's service life. Recovering over a wet or failing deck just buries the problem — we'll tell you honestly when that's the case.
A real commercial assessment is what tells the two apart — see what's covered below.
What we actually check
What a commercial roof assessment covers
Membrane & seam condition
Every seam, lap, and field section of the membrane is checked for splits, alligatoring, blistering, and loss of adhesion — the places a low-slope roof actually fails.
Drainage & ponding
A flat roof has no slope to hide a drainage problem. We check scuppers, drains, and low spots for standing water, which accelerates membrane failure wherever it collects.
Flashing & penetrations
HVAC curbs, pipe penetrations, parapet walls, and roof-edge flashing are the most common leak sources on a commercial roof — each gets checked individually.
Written, photo-documented findings
You get a written condition report with photos — the record an owner, a board, or an insurer can act on, not a verbal opinion.
Built for how you operate
Not a residential process wearing a commercial label
Scheduling around your building
Commercial roof work gets sequenced around your operating hours, tenant leases, and foot traffic — not run on a residential timeline that assumes an empty house all day.
Minimizing tenant disruption
Staging, access routes, and noise-heavy work windows get planned in advance so tenants and customers are disrupted as little as possible while the roof gets done.
Documentation for owners & insurers
Assessment reports, photos, and scope-of-work documentation are written to hold up with an ownership group, a board, or a carrier — not just a homeowner's own memory of the visit.
Maintenance programs, not just emergencies
A low-slope roof's biggest enemy is a small problem left alone. Periodic maintenance inspections catch failing seams and clogged drainage before they become an interior leak.

Common questions
Commercial roofing FAQ
- Does Liberty Roofing work on commercial buildings?
- Yes. Liberty Roofing Company services commercial and flat roofing systems across Baldwin and Mobile County — EPDM, modified bitumen, and built-up (BUR) roofing — alongside our residential shingle and metal roofing work.
- What's the difference between commercial and residential flat roofing?
- The systems overlap, but the buyer and the process don't. A commercial roof usually means a larger membrane area, tenant scheduling, and documentation that has to satisfy an owner, a property manager, or an insurer — not just one homeowner. Our residential flat-roofing work covers the same core systems for flat sections of a house, like a porch roof or a modern addition.
- What's the difference between TPO, EPDM, and modified bitumen?
- All three are low-slope roofing membranes. TPO is a single-ply thermoplastic membrane, heat-welded at the seams. EPDM is a synthetic rubber membrane, one of the most established low-slope systems on the market. Modified bitumen is an asphalt-based membrane installed in rolled plies. Liberty installs and services EPDM, modified bitumen, and built-up (BUR) systems; if your building's existing roof is TPO or you're evaluating it as an option, tell us during your assessment and we'll talk through what fits your building.
- How do you minimize disruption to tenants during a re-roof?
- We plan staging areas, access routes, and the noisiest phases of the work around your building's operating hours and tenant leases, and walk through the schedule with you before work starts — not after.
- Do you provide documentation I can give to ownership or my insurance carrier?
- Yes. Every commercial assessment includes a written, photo-documented condition report — the kind of record an ownership group, a property management company, or an insurance adjuster can act on.
