Commercial Roofing in Clayton, MO

Commercial roof problems can affect tenants, operations, interiors, customer areas, and capital plans. CGR Legacy Construction helps Clayton property owners and managers assess leaks, aging roof systems, storm concerns, and replacement planning with a clear commercial roofing scope.

Start with the building, the problem, and the roof condition. We inspect, document what we find, explain the realistic options, and help you plan the next step.

Commercial Roof Problems We Help Evaluate

Commercial roofing calls usually start with a business problem, not a product name.

Active Leak

Water is entering the building now or showing up around ceilings, walls, equipment, or tenant spaces.

Recurring Leaks

The same area - or multiple areas - has been repaired before and the underlying cause is still unclear.

Aging Roof System

The roof is becoming harder to maintain and you need to understand remaining serviceability, risk, and replacement timing.

Storm Concern

Hail or wind moved through the area and you need roof-condition documentation before deciding what to do next.

Capital Planning / Unknown Condition

You need a clearer picture of the roof before budgeting, purchasing, refinancing, renewing a lease, or planning facility work.

Commercial Roof Planning in Clayton Has to Fit the Building and the Operation

Clayton is a concentrated commercial market, not one building type. The City currently reports more than 3,400 businesses, an approximate 45,000-person daily workforce, about 10 million square feet of office space, and about 1 million square feet of retail space.

The Central Business District, Forsyth Gateway, Maryland Gateway, mixed-use properties, institutional campuses, hospitality, retail, and professional office environments can create very different roof-access, staging, tenant, customer-traffic, equipment, parking, and sequencing requirements.

CGR should plan around the actual property. Dense or multi-story context does not by itself establish high-rise, suspended-access, or specialty-equipment capability.

Start With the Roof Condition - Not a Preselected Product

A useful commercial roof assessment looks at the system as a whole. Depending on the building and safe access, the evaluation may include:

Roof field / membrane or surface condition
Seams, transitions, flashings, perimeter and edge details
Penetrations, curbs, rooftop equipment and attachment points
Drains, scuppers and visible drainage/ponding indicators

Previous repairs and recurring leak locations
Interior signs of water entry and the building’s leak history
Visible conditions that may justify additional moisture or assembly testing

The goal is to define what is known, what still needs verification, and which next-step options are realistic for the building.

The Right Commercial Roof Plan Depends on Condition, Not Assumptions

Targeted Repair: May make sense when the problem is localized and the surrounding roof assembly is still serviceable.

Restore / Coat: May make sense when the existing roof qualifies for restoration and defects are repaired first. CGR operating principle: We fix the roof before we coat the roof.

Recover: May be an option on some assemblies when the existing roof, moisture condition, code requirements, attachment, drainage, and manufacturer/system requirements support it.

Full Replacement: May make sense when deterioration is widespread, leaks are recurring across the system, the assembly is no longer a good restoration candidate, or long-term risk and capital planning favor replacement.

The assessment should narrow the options before the estimate locks in a scope.

Commercial Roofing Options for Different Roof Conditions

Commercial Roof Repair

Localized leaks, flashing issues, punctures, perimeter details, penetrations, and other repairable conditions.

Commercial Roof Replacement

Broader reroof planning when the existing system no longer supports a practical repair or restoration path.

Flat / Low-slope Roofing

Assessment and scope planning for low-slope commercial roof assemblies.

TPO Roofing

A single-ply option that may fit qualifying low-slope replacement or reroof projects when the system design supports it.

Commercial Roof Coatings

Restoration option for qualifying roofs after defects and eligibility are evaluated.

Exact product, manufacturer, thickness, attachment, insulation, warranty, and installation method must be confirmed for the project before publication or proposal use.

A Commercial Roof Scope Has to Work Around the Building

Commercial roofing is not only a roof decision. The project plan may need to account for:

From Roof Problem to Clear Commercial Scope

1. Initial Contact

Tell us about the property, roof concern, leak history, urgency, occupancy, and any known system details.

2. Roof Assessment

We review accessible roof conditions, problem areas, drainage, details, and relevant interior/operational context.

3. Findings + Options

We explain what appears repairable, what needs more verification, and whether restoration, recover, or replacement should be considered.

4. Scope + Estimate

The proposed work is documented with the scope, assumptions, exclusions, and planning requirements appropriate to the project.

5. Production Planning

Before work, align access, staging, weather, occupants, equipment, communication, and project sequencing.

6. Execution

Complete the approved scope, document the work, address cleanup/closeout items, and provide agreed project records.

If a Commercial Roof Is Leaking, Start With Safety and Documentation

If water is entering an occupied building, protect people, equipment, inventory, and interior areas first when it is safe to do so. Document where water is showing up, when it occurs, and any visible exterior conditions you can observe safely.

Call CGR at (636) 251-4245 to discuss current availability and the safest next step.

Clayton has verified severe-weather history. NWS St. Louis documented a tornado touching down in Clayton around 2:41 p.m. on May 16, 2025 before strengthening as it moved east into the City of St. Louis. That history is context – it does not prove damage at a particular building.

If insurance is involved: the adjuster reviews coverage. CGR reviews the roof and construction scope.

Commercial Roofing FAQ - Clayton, MO

How do I know whether a commercial roof needs repair or replacement?

Start with the extent and cause of the problem, leak history, overall roof condition, moisture/assembly concerns, and long-term building plan. Localized issues may support repair; widespread or recurring failure may push the decision toward broader restoration, recover, or replacement planning.

Can a commercial roof be coated instead of replaced?

Sometimes. Coatings are a restoration option for qualifying roofs after defects are repaired and the existing assembly is shown to be a suitable candidate.

Do you work with flat or low-slope commercial roofs?

CGR evaluates commercial low-slope roofing needs and can help define repair, restoration, recover, or replacement scope. Exact system/product recommendations are project-specific.

Is TPO an option for my building?

It may be. TPO is one low-slope system option, but the right assembly depends on the building, existing roof, insulation, drainage, attachment, code, and project goals.

What if the building is occupied?

The project plan should address access, staging, tenants or employees, parking, customer traffic, rooftop equipment, interior protection, communication, and sequencing before work begins.

Can you help after hail, wind, or other severe weather?

CGR can inspect and document roof conditions after severe weather and explain the construction scope. The insurance carrier/adjuster determines coverage.

Do commercial roofing projects in Clayton require permits or architectural review?

Requirements depend on the property, exterior impact, work method, and scope. Verify the address and project with the City before relying on a blanket answer.
