ROOFING DONE RIGHT. START TO FINISH.

Commercial Roofing in St. Louis, MO

CGR Legacy Construction helps property owners, property managers, and commercial decision-makers evaluate leaks, storm damage, drainage problems, aging low-slope systems, and long-term roofing costs. We inspect the roof, define the condition and scope, and recommend the most practical path—repair, restoration/coating, or replacement.

Commercial roofing options may include targeted repair, flat/low-slope roof service, TPO, fluid-applied roof coatings, or full replacement depending on the roof’s condition.

Commercial Roofing Help for Leaks, Storm Damage, and Aging Roof Systems

Commercial roof problems can affect tenants, inventory, equipment, interior finishes, operations, and long-term budgeting. A leak may be isolated. Ponding or membrane wear may point to a broader system issue. An older roof may still be a good repair or restoration candidate—or it may be reaching the point where replacement is the better long-term decision.

The first step is to understand the condition of the roof and define the scope. CGR should inspect the system, identify the problem areas, and explain whether repair, restoration/coating, or replacement makes the most practical sense for the building.

Clear inspection findings. Defined scope. Straightforward next-step guidance.

Commercial Roof Coatings

Repair, Restore, or Replace? Start With the Roof Condition

Not every commercial roof needs the same solution. A localized problem may only need repair. A roof that still has serviceable life may be a candidate for restoration with a fluid-applied coating. A roof with widespread deterioration, unresolved moisture, repeated failures, or broader system problems may need replacement. The inspection should determine the path—not the product we want to sell.

Repair

Target the leak or damaged area, then monitor overall system condition.

Restoration / Coating

Restore and protect the existing roof with an approved fluid-applied coating system when the roof qualifies.

Replacement

Replace the system when a repair or coating would only postpone a larger failure.

A Lower-Upfront-Cost Roof Restoration Option for Eligible Commercial Roofs

Some commercial roofs do not need an immediate tear-off and full replacement. When the existing roof is still a good restoration candidate, a fluid-applied elastomeric coating system may help renew surface protection, address vulnerable surface areas, and extend useful service life with less disruption and a lower upfront investment than a complete reroof.

CGR now has field experience completing commercial roof coating work and can evaluate whether a coating approach makes practical sense for the building. The roof still has to qualify. Existing leaks, damaged areas, seams, flashings, penetrations, drainage concerns, surface condition, and product compatibility should be addressed before the coating system is applied.

What “elastomeric” and “polyurethane” actually mean

  • Elastomeric is a performance/category term for a flexible roof coating that can stretch and recover as the roof moves.
  • Polyurethane / urethane is one roof-coating chemistry. Other common coating chemistries include acrylic and silicone.
  • A liquid polyurethane roof coating is not the same thing as spray polyurethane foam (SPF) roofing.
  • Depending on the manufacturer and system, coatings may be spray-applied, rolled, or brushed. The exact application method must match the approved product instructions.

Lower Upfront Investment

For an eligible roof, restoration can require less material and labor than a tear-off/replacement, which can reduce the upfront project cost.

Less Business Disruption

Fluid-applied restoration can often be completed with less disruption than a full tear-off, depending on building conditions and project scope.

Life-Extension Strategy

A coating can help protect a serviceable existing roof and postpone replacement when the system condition supports restoration.

Seamless Surface Protection

Roof coatings cure into a continuous protective film and can add weathering/water-resistance performance when properly specified and applied.

How Our Roofing Process Works

Initial Contact

Tell us about the property, current roof problem, leak history, known system type, timing, and operational constraints.

Commercial Roof Assessment

We inspect visible roof conditions and problem areas and gather the information needed to define the likely scope.

Scope & Solution Review

We explain whether the roof looks like a repair, restoration/coating, or replacement candidate and what additional information is needed before final pricing.

Estimate & Planning

You receive a written scope, pricing, scheduling expectations, and any approved alternates that make sense for the building.

Project Execution

Once approved, we coordinate the work with communication, access, safety, cleanup, and business disruption in mind.

Final Review

Confirm completion, document finished conditions, review any owner maintenance expectations, and close out project records.

Why Property Owners and Managers Choose CGR for Commercial Roofing

Commercial roofing decisions require clear communication, realistic recommendations, and a contractor that understands the cost of disruption.

  • Condition-First Recommendations: Assess the roof before deciding whether the building needs repair, restoration, or replacement.
  • Clear Written Scope: Define what is being addressed, what is not, and the recommended next step before work begins.
  • Commercial Decision Support: Help owners compare immediate repair needs with longer-term capital planning and restoration/replacement options.
  • Storm & Leak Documentation: Document visible roofing conditions and storm-related issues from the contractor side when relevant.
  • Organized Project Communication: Keep scheduling, access, jobsite expectations, and project communication clear.
  • Local St. Louis Service: Commercial roofing support across the St. Louis / St. Charles market and nearby service areas.

Larger commercial roofing projects can create timing and capital-planning pressure. Financing options may be available for qualified projects. Review available financing only after the roof scope and project needs are understood.

Roof Repair FAQs

CGR provides commercial roof assessment, repair, replacement, flat/low-slope roofing support, TPO roofing, storm-related roofing work, and roof coating/restoration options for eligible commercial roofs.

That depends on roof type, age, leak history, overall condition, extent of damage, moisture or deterioration concerns, and whether the existing system is still a practical restoration candidate. The roof assessment should determine the path.

An elastomeric roof coating is a fluid-applied coating that cures into a flexible protective film over an eligible roof surface. It can be part of a roof restoration strategy when the existing roof is still suitable for coating.

No. A liquid polyurethane or urethane roof coating is a coating chemistry. Spray polyurethane foam (SPF) is a different roofing material/system. CGR should identify the exact product and system being proposed for each project.

A coating can be part of a leak/restoration solution on an eligible roof, but it should not be treated as a blanket spray-over fix. Leaks, damaged areas, seams, flashings, penetrations, substrate condition, drainage, and moisture concerns may need repair or preparation first.

A coating is better described as a restoration or life-extension strategy for an eligible existing roof. It is not the same as removing and installing a completely new roof system. Service life depends on the specific system, preparation, roof condition, maintenance, and manufacturer requirements.

For a roof that qualifies, restoration can often require less time, labor, and new material than a full tear-off and replacement, which can reduce upfront cost. The actual comparison depends on the building and scope.

Yes. The page should route flat and low-slope needs into the correct service path, including repair, TPO, coatings, or replacement depending on the roof condition.

Yes. CGR can inspect visible storm-related roofing conditions, document the contractor-side findings, and provide a recommended scope for repair, restoration, or replacement when appropriate.
