A hailstorm can pass through San Angelo in minutes.
The building assessment that follows should not be rushed.
Commercial roofs contain membranes, insulation, sheet metal, drains, skylights, rooftop equipment, flashings, and numerous penetrations. Each component may respond differently to impact.
Some damage is immediately visible. Some is subtle. Some marks may be cosmetic, while other conditions may affect performance even before interior water entry appears.
A professional assessment should document what happened, identify observed roofing conditions, distinguish damage from pre-existing wear where possible, and develop a technically supportable roofing recommendation based on evidence.
Mammoth Services helps San Angelo facility teams document post-storm conditions, evaluate the complete roof environment, identify immediate risks, and develop a practical path forward based on actual findings.
A Hailstorm Can Pass Quickly, but the Assessment Should Not Be Rushed
Facility managers, property owners, plant managers, maintenance directors, school administrators, public-facility representatives, property-management firms, operations managers, and capital-project managers across San Angelo and West Texas all face the same question after a storm: what actually happened to the roof? The answer should come from a careful, component-by-component review, not a rushed guess.
What to Do After a Commercial Hailstorm
The list below is a starting checklist, not a substitute for a professional assessment.
Protect people from electrical, slip, and falling-object hazards.
Document the storm date and approximate time.
Photograph interior leaks and visible exterior conditions.
Protect vulnerable materials and equipment when safe to do so.
Mark interior leak locations.
Limit unnecessary roof traffic.
Preserve records of any emergency work performed.
Review manufacturer warranty notification requirements.
Arrange a qualified commercial roof assessment.
Roof access should be limited to qualified personnel using appropriate safety procedures. Untrained staff should not attempt to inspect or walk the roof after a storm.
No Immediate Leak Does Not Prove the Roof Is Undamaged
A roof can sustain impact damage without leaking during the same storm.
Possible conditions include:
Membrane fractures
Surface damage
Cracked coatings
Damaged insulation
Dented metal
Open seams
Broken skylights
Damaged vents
Displaced flashing
Compromised rooftop equipment
Loosened components
Water entry may not begin until a later storm exposes the damaged location.
Functional damage may exist before interior water entry becomes visible.
That is why the post-storm inspection should not be limited to interior leak areas.
Start With a Storm Documentation File
The facility should open a dedicated incident file containing:
Date and approximate time
Hail observations
Photographs and videos
Interior leak reports
Employee or occupant observations
Security-camera footage when available
Emergency work records
Previous roof photographs
Warranty documents
Prior contractor reports
Relevant material records
Communications related to the event
The purpose is not to assume that replacement is required. It is to preserve accurate information before conditions, debris, temporary repairs, or additional weather alter the evidence.
Protect the Building Before Permanent Repairs Begin
When active water entry is occurring:
Protect people from electrical and slip hazards.
Move or cover vulnerable materials when safe.
Mark interior leak locations.
Photograph conditions.
Use qualified personnel for roof access.
Complete necessary temporary protection.
Preserve removed materials when appropriate.
Document all emergency work.
Temporary work should be clearly identified as temporary. Permanent repairs should follow after the affected areas have been properly evaluated.
For a roof with an active leak that needs an immediate response, Mammoth's emergency commercial roof leak repair guidance covers the same protect-first priorities in more depth.
Inspect the Complete Commercial Roof Assembly
Inspection methods depend on roof type, access, safety, observed conditions, warranty requirements, and owner authorization. Destructive testing is not performed without approval.
TPO, PVC, and EPDM Roofing
These single-ply membrane systems should be examined for punctures, fractures, splits, displaced seams, surface damage, and damage over hard substrate transitions.
Modified-Bitumen and Built-Up Roofing
Inspect for fractures, displaced surfacing, punctures, damaged flashings, and impact patterns.
Metal Roofing and Sheet-Metal Components
Dents may be cosmetic, functional, or both, depending on location and severity. Seams, fasteners, coatings, joints, and drainage behavior should be assessed.
Roof Insulation and Substrate
Impact can affect insulation below the membrane. The need for test cuts or other investigation depends on observed conditions, roof construction, and owner authorization.
Skylights and Translucent Panels
These components may crack, fracture, or become brittle and should be treated as a safety concern.
HVAC and Rooftop Equipment
Inspect HVAC panels, coils, vents, fans, ducts, curbs, rain guards, and electrical components.
Drains, Scuppers, Gutters, and Downspouts
Check drain strainers, scuppers, gutters, and downspouts for impact damage or obstruction. Persistent ponding or blocked drainage after a storm may point to a separate drainage issue that deserves its own review.
Flashings and Penetrations
Review walls, curbs, pipes, pitch pockets, expansion joints, and other transitions.
Cosmetic Versus Functional Hail Damage
The distinction between cosmetic and functional damage should be based on evidence, material behavior, and the affected component, not on appearance alone.
Questions may include:
Has the material fractured?
Has water-shedding ability changed?
Has a seam or joint opened?
Has the protective surface been compromised?
Has the component's intended performance changed?
Is the condition consistent across exposed areas?
Does the manufacturer provide relevant guidance?
Is additional testing warranted?
A photograph of a dent by itself may not answer these questions.
Use Comparison Areas and Pre-Storm Records
When appropriate, the assessment may compare:
Exposed and sheltered areas
Different roof elevations
Different materials
North-, south-, east-, and west-facing components
Recently installed and older sections
Areas beneath equipment overhangs
Pre-storm maintenance photographs
Comparison helps separate storm-related conditions from age, installation defects, or pre-existing wear. NRCA's technical guidance on evaluating roof condition supports this same comparative approach.
Avoid Creating Additional Damage During Inspection
A hail inspection should be systematic.
Uncontrolled foot traffic can:
Damage brittle materials
Disturb loose components
Create punctures
Alter evidence
Spread contaminants
Create safety exposure
Roof access should be limited to qualified personnel following appropriate safety procedures, consistent with OSHA fall-protection requirements.
When Moisture Testing May Be Appropriate
Surface inspection does not always show whether water has entered the assembly.
Depending on the roof and observed conditions, the investigation may include:
Infrared scanning
Electrical capacitance or impedance methods
Nuclear scanning
Test cuts
Core samples
Interior inspection
Not every roof requires every method. Some testing requires qualified specialty providers, and weather and roof construction can affect results. Non-destructive findings may require targeted verification, and test cuts or core samples require owner authorization. Warranty or consultant coordination may be necessary, and results must be interpreted in context. Thermal anomalies alone do not prove moisture or hail damage; they indicate areas that may warrant further investigation.
Possible Outcomes of a Commercial Hail Assessment
A hail assessment may lead to one of five findings:
No Functional Storm Damage Identified
Document the condition and retain the report as part of the roof record.
Localized Repair
Repair specific damaged components and document the completed work. See Mammoth's commercial roof repair services for more on how localized repairs are scoped and completed.
Sectional Replacement
Replace affected roof areas when damage is concentrated or assemblies differ by section.
Restoration
A restoration system may be considered when the existing assembly is otherwise suitable and the proposed system addresses the identified conditions.
Full Replacement
Full replacement may be appropriate when damage is widespread, the assembly is no longer serviceable, or repairs would not produce a reliable long-term result.
The recommendation should follow the evidence, not a predetermined sales outcome.
Coordinate Permanent Repairs With the Warranty Provider
Warranty requirements vary by manufacturer, roof system, and project. Before permanent repairs begin, the owner should review the specific warranty and contact the issuing manufacturer or authorized representative when required.
Review:
Notification deadlines
Approved repair materials
Approved contractors
Inspection requirements
Documentation requirements
Temporary repair procedures
An emergency repair does not automatically void every manufacturer warranty, but repair materials, contractors, and documentation should match the specific system's requirements. GAF's hail-system guidance outlines how commercial roof assemblies are rated and warrantied for hail exposure.
What a Professional Commercial Hail Report Should Contain
A credible report may include:
Property identification
Inspection date
Weather-event reference
Roof plan
Roof assembly description
Photographs
Damage locations
Component-by-component findings
Interior observations
Testing results
Limitations
Recommended actions
Immediate temporary work
Proposed permanent scope
Maintenance considerations
The report should distinguish observations from conclusions.

Why Local West Texas Experience Matters
San Angelo property owners need a contractor who understands both commercial roofing and West Texas weather exposure.
The assessment should account for:
Heat-aged materials
Existing repairs
Strong solar exposure
Wind effects
Hail impact
Sudden rainfall
Drainage
Rooftop equipment
Facility operations
Not every roof mark is hail damage, and not every hail-damaged roof needs full replacement.
The owner needs a fair, documented, and technically supportable answer.

Frequently Asked Questions
How soon should a commercial roof be inspected after hail?
The owner should document immediate conditions promptly and arrange a qualified assessment as soon as safely practical, especially if leaks or visible damage are present.
Can a roof be damaged without leaking immediately?
Yes. A roof can sustain impact damage without leaking during the same storm, and water entry may not begin until a later storm exposes the damaged location.
Can TPO roofing be damaged by hail?
Yes. The outcome depends on hail size, impact energy, membrane condition, substrate, insulation, and assembly design.
Does dented metal always require replacement?
Not always. The location, severity, coating condition, seams, fasteners, and effect on function must be evaluated.
Should HVAC equipment be included in the inspection?
Yes. Coils, panels, vents, curbs, ductwork, and related components may sustain damage independent of the roof membrane.
Is full replacement always required?
No. The appropriate response may be documentation only, localized repair, sectional replacement, restoration, or full replacement, depending on actual findings.
Why is pre-storm documentation valuable?
Previous photographs and reports help distinguish new storm effects from existing deterioration, repairs, or installation conditions.
Can hail damage affect roof insulation?
Yes. Impact can affect insulation below the membrane. The need for test cuts or other investigation depends on observed conditions and roof construction.
When is moisture testing appropriate?
Moisture testing may be appropriate when surface inspection does not clearly show whether water has entered the assembly. The specific method depends on the roof type, observed conditions, and owner authorization.
Does hail damage automatically void a warranty?
Not automatically. Warranty requirements vary by manufacturer, roof system, and project. The owner should review the specific warranty and contact the issuing manufacturer or authorized representative when required.
Can temporary repairs be completed before the full assessment?
Yes, when needed to protect the building. Temporary work should be clearly identified as temporary, and permanent repairs should follow after the affected areas have been properly evaluated.
What should a professional hail report include?
A credible report should include property and roof identification, the inspection date, a weather-event reference, photographs, component-by-component findings, testing results and limitations, and recommended actions, while distinguishing observations from conclusions.
Can Mammoth inspect multiple buildings?
Yes. Mammoth Services can coordinate assessments across multiple buildings or roof areas as part of a single facility or campus assignment.
Does Mammoth determine insurance coverage?
No. Mammoth Services documents visible roofing conditions and develops roofing recommendations. Insurance coverage, engineering, code, warranty, and claim decisions may require review by the appropriate insurer, engineer, consultant, manufacturer, or licensed professional.
What records should a facility manager provide before the inspection?
Helpful records include prior roof photographs, maintenance history, warranty documents, previous contractor reports, and any existing storm documentation file for the property.
