Why Fast Response Is Critical for Commercial Properties
A compromised commercial roof doesn't just threaten the building — it threatens your business operations, inventory, equipment, and tenant relationships. Water infiltration through a damaged roof can destroy merchandise, short electrical systems, trigger mold growth, and force costly business interruptions within 24 to 48 hours of a storm event. Commercial insurance policies also carry strict notice requirements: failing to report damage promptly can jeopardize your claim. The faster you act, the more you protect — your building, your business, and your coverage.
Business Interruption Risk
Roof leaks can force you to close sections of your facility, relocate operations, or shut down entirely — costing far more than the repair itself.
Inventory & Equipment Damage
Water infiltration can destroy merchandise, damage machinery, and ruin electronics in hours. A temporary fix now prevents catastrophic losses later.
Tenant & Liability Exposure
Property owners have a duty to maintain safe conditions. Unaddressed storm damage creates slip-and-fall hazards and potential liability for tenant property damage.
Insurance Claim Deadlines
Most commercial policies require prompt notice of loss. Delayed reporting can reduce or void your coverage — even for legitimate storm damage.
Structural Deterioration
Commercial roof membranes and decking deteriorate rapidly once compromised. What starts as a puncture or seam failure can become a full deck replacement.
Compounding Storm Exposure
Texas averages over 100 severe weather days per year. A damaged roof is exponentially more vulnerable to the next storm — don't leave your property exposed.
Commercial Roof Systems We Service
Every commercial roof system responds differently to storm damage. Our inspectors are trained on all major commercial roofing systems used across Texas.
TPO / PVC Membrane
Storm vulnerability: High wind uplift, punctures from hail and debris, seam separation
Seam re-welding, patch repairs, full membrane replacement when damage is widespread. TPO is the most common commercial roofing system in Texas and requires specialized heat-welding equipment for proper repair.
Signs of damage
- Visible punctures or tears
- Lifted or separated seams
- Pooling water at new locations
- Bubbling or blistering membrane
EPDM (Rubber) Membrane
Storm vulnerability: UV degradation accelerated by storm exposure, punctures, shrinkage at seams
EPDM patch repairs using compatible adhesive systems, seam re-bonding, and full replacement for aged or extensively damaged membranes.
Signs of damage
- Cracks or splits in membrane
- Seam lifting or peeling
- Shrinkage pulling away from edges
- Water stains on interior ceilings
Modified Bitumen
Storm vulnerability: Hail bruising, granule loss, blister formation, flashing failures
Torch-applied or cold-applied patch repairs, flashing replacement, and full re-roofing when base layers are compromised.
Signs of damage
- Granule loss in drainage areas
- Blistering or bubbling surface
- Cracked or split seams
- Flashing separation at walls and curbs
Metal Roofing
Storm vulnerability: Hail denting, fastener back-out, panel seam separation, coating damage
Panel replacement, fastener re-seating and sealing, seam re-crimping, and full coating restoration to prevent rust and UV degradation.
Signs of damage
- Visible dents across panel field
- Rust streaking at fastener points
- Lifted or separated panel seams
- Leaks at ridge caps or transitions
Built-Up Roofing (BUR)
Storm vulnerability: Hail impact damage through multiple plies, flashing failures, gravel displacement
Ply patching, flood coat and gravel restoration, flashing replacement, and full tear-off when structural layers are compromised.
Signs of damage
- Gravel displacement exposing felt
- Alligatoring or surface cracking
- Flashing separation at walls
- Interior water stains or active leaks
Steep-Slope Commercial
Storm vulnerability: Same hail and wind damage as residential — shingle loss, flashing failure, ridge damage
Shingle repair and replacement, flashing re-sealing, ridge cap restoration, and full replacement when damage is widespread across the field.
Signs of damage
- Missing or displaced shingles
- Granule loss in gutters
- Damaged ridge caps
- Flashing separation at walls and penetrations
How to Identify Commercial Storm Damage
Commercial storm damage is often invisible from ground level. Here's what our certified inspectors assess during a post-storm commercial roof evaluation.
Roof Surface
Membrane Punctures & Tears
Hailstones and wind-driven debris puncture flat roof membranes, creating immediate water infiltration pathways. Even small punctures allow significant water entry during subsequent rain events.
Seam Separation
High winds create uplift pressure that separates membrane seams — the most common failure point on flat commercial roofs. Separated seams allow water to travel laterally beneath the membrane.
Granule Loss on Modified Bitumen
Hail strips the protective granule coating from modified bitumen roofs, accelerating UV degradation and dramatically shortening roof lifespan.
Metal Panel Denting
Hail leaves visible dents across metal roof panels and disrupts the panel's drainage geometry, creating ponding areas and accelerating corrosion at impact points.
Flashings & Penetrations
Flashing Separation at Walls
Wind uplift separates base and counter flashings at parapet walls — one of the most common commercial storm damage failure points and a direct pathway for water infiltration.
HVAC Curb Flashing Damage
Commercial roofs have numerous HVAC units, skylights, and pipe penetrations. Storm damage to curb flashings around these penetrations creates immediate leak points.
Drain & Scupper Damage
Debris accumulation and physical damage to roof drains and scuppers causes ponding water — adding structural load and accelerating membrane deterioration.
Coping Cap Displacement
High winds displace or damage metal coping caps at parapet walls, exposing the wall assembly to direct water infiltration and accelerating structural deterioration.
Interior & Structural
Ceiling Water Stains
Water stains on interior ceilings indicate active or past water infiltration. The stain location rarely corresponds directly to the roof entry point — water travels laterally before dropping.
Wet or Saturated Insulation
Roof insulation absorbs and retains water long after a storm, adding structural load, reducing thermal performance, and creating conditions for mold growth.
Deck Deterioration
Prolonged water exposure deteriorates roof decking — wood decks rot, steel decks rust, and concrete decks develop spalling. Deck damage significantly increases repair costs.
Mold or Musty Odors
Mold growth begins within 72 hours of water intrusion. Musty odors in interior spaces are a strong indicator of active moisture infiltration requiring immediate attention.
Emergency Tarping & Temporary Protection
When a storm causes immediate roof failure, we deploy emergency protective measures to stop water infiltration before permanent repairs begin.
Onyx Storm Roofing provides emergency tarping and temporary waterproofing for commercial properties that have sustained significant storm damage. Our crews can mobilize quickly after a storm event to install heavy-duty protective coverings over damaged roof areas, preventing further water infiltration while we document damage, process your insurance claim, and schedule permanent repairs. Emergency protection is especially critical for commercial properties where water infiltration can destroy inventory, damage equipment, and force business closures.
Heavy-Duty Roof Tarping
Commercial-grade tarps secured with ballast or mechanical fasteners to provide immediate waterproofing over large damaged areas.
Temporary Membrane Patching
Emergency patch repairs using compatible membrane materials to seal punctures, tears, and seam separations until permanent repairs are completed.
Debris Removal & Drain Clearing
Storm debris removal from roof surfaces and drainage systems to restore proper water flow and prevent ponding during subsequent rain events.

Commercial Insurance Claim Walkthrough
Commercial property insurance claims are more complex than residential claims. Our team has the experience to navigate the process and secure the full settlement your policy provides.
Commercial storm damage claims involve larger dollar amounts, more complex policy language, and more rigorous adjuster scrutiny than residential claims. Property owners who attempt to navigate the process alone frequently receive settlements that undervalue the true scope of damage. Onyx Storm Roofing has helped commercial property owners across Texas secure full, fair insurance settlements — and we'll do the same for you.
Review Your Policy Before Filing
Commercial policies vary significantly in coverage terms, deductibles, and notice requirements. We review your policy with you to understand your coverage, identify any exclusions, and determine the best approach before filing.
Document the Storm Event
We pull certified weather data for your property's location and date of loss — hail size, wind speed, and storm track — to establish the storm event as a covered peril and support your claim.
Independent Damage Assessment First
We complete our full damage assessment before your insurer's adjuster visits. This gives you an independent, documented record of all damage — ensuring nothing is missed or minimized during the adjuster inspection.
File the Claim with Full Documentation
We prepare and submit your claim with our complete damage report, photos, measurements, and weather data — giving your insurer everything needed to process the claim efficiently.
Adjuster Meeting Representation
Our team attends the adjuster inspection with you, walking the roof together and pointing out every damage item. We ensure the adjuster's scope matches the actual damage — not a minimized version of it.
Settlement Review & Supplement Filing
We review the insurance settlement line by line against our damage report. When items are missed or undervalued — which is common on commercial claims — we prepare a detailed supplement and advocate for the correct amount.
Depreciation Recovery (RCV Policies)
If your policy provides Replacement Cost Value coverage, we help you recover the withheld depreciation after repairs are completed — a step many property owners miss, leaving significant money on the table.
Final Payment Coordination
We coordinate directly with your insurer on final payment, handle any mortgage company endorsement requirements, and ensure all paperwork is complete before closing the claim.
