Texas Commercial
Due Diligence
Starts With the Roof.
The roof is the largest near-term capital exposure on most commercial acquisitions — and the first system that tells you what the asset is really worth. Imperial Pro delivers independent, drone-documented commercial roof inspections across the Texas Texaplex. TPO, EPDM, metal, BUR, and all flat roof systems. Written reports in 48 hours.
The Inspector Who
Profits From Honesty.
Not From Your New Roof.
When a roofing contractor offers you a "free commercial roof inspection," understand what you are getting: a sales call performed on your roof. The inspector makes money when they sell you a repair or replacement. Their financial incentive runs directly against yours.
Imperial Pro is a TREC-licensed independent commercial inspector — not a roofing contractor, not affiliated with any roofing manufacturer or installer. We have no financial interest in whether your roof needs work or not. If it's in good condition, we'll say so. If it's failing, we'll document exactly what, where, why, and what it will cost — with drone photography and thermal imaging to back every claim.
That independence is worth something. To your lender reviewing a due diligence package. To your insurance adjuster evaluating a storm claim. To the seller whose contractor told you the roof "needs replacing" but your independent inspector says it has eight years left. The difference between a contractor's opinion and an independent inspector's report can be a six-figure negotiation.
Why Buyers, Owners & Lenders Call Us
Buyers: "The seller's roofer said the roof is fine. We want a second opinion from someone who doesn't have a bid on the line."
Portfolio managers: "We need five roofs inspected across the Texaplex before quarter close. Consistent methodology, one vendor, 48-hour reports."
Insurance disputes: "The adjuster is denying our hail claim. We need an independent inspection report with drone documentation to support appeal."
Warranty verification: "The new roof was installed six months ago. We want an independent inspection before the contractor's warranty clock runs out."
Annual maintenance: "Our property manager handles routine work. We want an independent set of eyes on the roof once a year — someone who can't be influenced by the maintenance vendor."
Every Reason a Commercial
Building Needs a Roof Inspection
From pre-purchase due diligence to post-storm insurance documentation, independent commercial roof inspections serve a dozen distinct situations — each with its own risk and its own use for the report.
Buying a Commercial Property
The roof is often the single largest near-term capital expense on a commercial acquisition. Before you close, you need to know: how much life is left, what repairs are deferred, and what replacement will cost. A pre-purchase roof inspection gives you that number — backed by drone photography and written documentation — so you can negotiate a price adjustment, require a credit, or walk away with eyes open. This inspection can stand alone or be incorporated into a full ASTM E2018 PCA.
Filing or Defending a Roof Damage Claim
Hail. Wind. Hurricane. Tornado. Texas delivers all of them. When a weather event damages your commercial roof, an independent inspection report with drone documentation is your most powerful tool with the insurance adjuster — and, if necessary, in coverage disputes. Imperial Pro's written reports and aerial photography provide the third-party documentation adjusters require to validate claims. Because we are independent — not the roofing contractor who profits from the claim — our reports carry weight that contractor assessments often don't.
After Hail, Wind, Hurricane or Freeze Events
Texas storms don't announce the damage they leave behind. Hail impact on a TPO membrane, wind-lifted flashings on a BUR system, or debris punctures on EPDM can go undetected for months — until the first heavy rain reveals them as interior water damage worth multiples of what timely roof repair would have cost. Post-storm inspection within 30–60 days is the industry-standard best practice for preserving your insurance coverage window and catching damage before it compounds. Imperial Pro deploys drone photography to document impact patterns that aren't visible from ground level.
Active Leaks or Suspected Moisture Intrusion
Ceiling stains. Wet insulation. HVAC drain pan overflow. Interior mold growth. These are symptoms — the roof deficiency causing them may be thirty feet away from where the water appears inside. Infrared thermal imaging detects subsurface moisture entrapment in roofing assemblies that no visual inspection can find — wet insulation has different thermal mass than dry insulation, and the thermal camera maps the difference precisely. Imperial Pro uses IR thermal imaging to locate the actual infiltration points, not just the interior manifestation.
Annual or Biannual Maintenance Inspections
Commercial roofing manufacturers and warranty programs consistently recommend semi-annual inspections — spring (after winter stress) and fall (before hurricane/storm season). Annual independent inspections extend roof life, preserve warranty coverage, and catch $500 problems before they become $50,000 ones. For property managers overseeing a portfolio, regular independent inspection creates the documentation trail that supports maintenance budgeting, capital reserve planning, and board reporting.
Post-Installation Quality Assurance
A new commercial roof installation — TPO, EPDM, metal, or modified bitumen — represents a significant capital investment. Manufacturer warranties require proper installation, and most are void if installation defects go unchallenged. An independent post-installation inspection before the contractor's warranty period closes is the only way to verify seam integrity, membrane thickness specification compliance, flashing termination quality, penetration sealing, and drainage design — while you still have legal recourse. This is quality assurance that the contractor cannot perform on their own work.
Commercial Financing & ASTM PCA Integration
CMBS lenders, SBA lenders, and institutional debt funds require detailed roofing condition documentation — including Estimated Remaining Useful Life (ERUL) and Estimated Probable Cost (EPC) of replacement — in their Property Condition Reports. When Imperial Pro conducts a full ASTM E2018 PCA, roofing is documented as a comprehensive section with drone imagery, ERUL assessment, and CAPEX reserve table entry. For portfolios or large assets, a standalone roof inspection can be commissioned first and the findings rolled into the PCA report.
Tenants & Landlords — Triple-Net Lease Inspections
In a triple-net or modified gross lease, the tenant often assumes responsibility for all or part of the roofing system. Before signing a NNN lease, both landlords and tenants need to know the roof's condition and remaining useful life — because a 15-year NNN lease on a building with a roof that has three years of life left is a very different financial reality than it appears on paper. Tenants who commission an independent roof inspection before lease execution can negotiate landlord responsibility for replacement, cap their roofing obligation, or reprice the deal.
Multi-Property Roof Condition Assessments
Asset managers and REITs managing commercial portfolios need consistent, comparable roof condition data across all properties — not a dozen different contractor opinions with different methodologies, terminology, and bias. Imperial Pro conducts portfolio roof inspections with standardized methodology, uniform reporting format, and CAPEX reserve data that rolls up into portfolio-level capital planning models. We recently completed a five-property commercial roof inspection contract across the Texas Texaplex, delivering consistent reports for each asset within a unified due diligence timeline.
Contractor Performance Disputes
Roof leaks after a recent replacement. Seam failures within a year of installation. A contractor blaming "unusual weather" for problems caused by deficient workmanship. An independent inspection report documents whether the failure is installation-caused or weather-caused — a distinction worth tens or hundreds of thousands of dollars in warranty claim value. Imperial Pro's written reports with close-up drone and infrared documentation provide the technical foundation for contractor performance disputes, mediation, and litigation support.
Sellers: Get Ahead of Buyer Due Diligence
Smart sellers commission an independent roof inspection before listing — not after a buyer's inspector finds something. A pre-sale roof inspection lets you price the asset accurately, make repairs on your timeline (not a buyer's deadline), and present buyers with third-party documentation that supports your asking price. It also removes the single most common re-trade trigger from the deal. Buyers who see an independent inspection report with clean findings are less likely to hire their own inspector — or if they do, your documentation gives them fewer grounds to renegotiate.
Reflectivity, Drainage & HVAC Load Assessment
In Texas's extreme heat environment, a degraded TPO membrane that has lost reflectivity can meaningfully increase HVAC load and energy costs — even if it isn't leaking yet. Thermal imaging reveals areas where the roof assembly is performing poorly, accumulating moisture, or failing to insulate as designed. Drainage deficiencies that cause ponding water — which accelerates membrane degradation — are documented with drone aerial photography. This operational intelligence matters to asset managers focused on NOI, not just structural risk.
Every Commercial
Roof Type We Inspect
Our inspectors are trained on all major commercial roofing systems in use across Texas. TPO is the dominant flat roof system in the Texaplex and receives our deepest technical focus — but we inspect every system a commercial building might carry. The assessment methodology adapts to the system. The independence never does.
TPO — Thermoplastic Polyolefin
The dominant commercial roofing membrane in Houston, San Antonio, Austin, and DFW. Single-ply white reflective membrane, heat-welded seams, engineered for Texas heat. Lifespan 20–30 years with proper maintenance.
- Seam integrity — heat-weld quality and delamination
- Membrane punctures, tears, and weathering
- Reflectivity degradation from UV and algae
- Flashing terminations at parapet walls
- Penetration sealing (HVAC curbs, drains, pipes)
- Ponding water patterns — drain slope adequacy
- Thermal imaging — subsurface moisture mapping
EPDM — Rubber Membrane
Ethylene propylene diene monomer — black or white rubber single-ply membrane. Common on older commercial buildings and industrial facilities. Susceptible to shrinkage and seam adhesive failure in Texas heat.
- Membrane shrinkage and flashing pull-away
- Seam and lap adhesive condition
- Puncture and mechanical damage assessment
- Drain collar integrity
- Ballasted vs adhered system conditions
PVC — Polyvinyl Chloride
Single-ply thermoplastic membrane, white or light-colored, with heat-welded seams similar to TPO. Strong chemical resistance — common over restaurant exhaust and industrial applications.
- Seam integrity and weld quality
- Chemical exposure degradation
- UV weathering and plasticizer migration
- Flashing detail condition
Modified Bitumen
APP or SBS modified bitumen — torch-applied or cold-applied multi-ply systems. Common on buildings constructed before the widespread adoption of single-ply TPO/EPDM. Often installed in two or three plies with granular surface cap sheet.
- Surface granule loss and blistering
- Lap seam adhesion failures
- Alligatoring and oxidation of surface ply
- Flashing condition at parapet and penetrations
- End-of-life assessment vs. coating/overlay potential
Built-Up Roofing (BUR)
Multi-ply felts and asphalt (or coal tar pitch) with gravel or mineral surface ballast. Found on older commercial buildings and still in service on many Texas properties. Complex to inspect — and expensive to replace.
- Aggregate loss and surface erosion
- Alligatoring and surface cracking
- Blistering and interply delamination
- Flashing condition at curbs and walls
- Substrate and structural deck condition
- Thermal imaging for subsurface moisture
Metal Roofing Systems
Standing seam, R-panel (exposed fastener), and corrugated metal roofing. Common on warehouses, industrial facilities, and agricultural-use commercial buildings across the Texaplex. Steep-slope and low-slope variants inspected.
- Panel corrosion, oil-canning, and thermal movement damage
- Exposed fastener pull-through and seal failure
- Standing seam panel clip and seam integrity
- Ridge cap, flashing, and closure strip condition
- Skylight, penetration, and curb flashing
- Hail damage impact pattern documentation (drone)
What's Included in Every
Commercial Roof Inspection
Every Imperial Pro commercial roof inspection includes drone aerial documentation and a written report as standard. No additional charge for basic drone coverage — it's part of how we do this job.
Standard Scope — Every Inspection
Full Roof Surface Walk-Through
Physical access to all accessible roof areas — membrane condition, seam integrity, flashings, penetrations, HVAC curbs, drains, and parapet walls documented on site.
Drone Aerial Documentation — Included
Complete overhead photographic coverage of the entire roof plane. Seam patterns, membrane damage, ponding areas, equipment placement, and perimeter conditions documented from the air — capturing what ground-level inspection misses.
Drainage & Ponding Assessment
Drain location, slope adequacy, and evidence of ponding water documented. Ponding is the primary accelerant of membrane degradation on flat commercial roofs.
Flashing & Penetration Detail Inspection
Parapet walls, roof-to-wall terminations, HVAC curbs, pipe boots, skylights, exhaust fans, and all penetrations inspected. The majority of commercial roof leaks originate at flashings, not mid-field.
Estimated Remaining Useful Life (ERUL)
Professional assessment of remaining service life — the number lenders, buyers, and asset managers require for capital reserve planning and financing qualification.
Written Inspection Report — 48 Hours
Comprehensive written report with photographs, drone imagery, deficiency descriptions, severity ratings, and repair/replacement recommendations. Delivered within 48 hours. Defensible, professional documentation ready for lender, insurance, or negotiation use.
Add to Any Roof Inspection
Scope your inspection to match your actual risk. Add services at the time of booking.
Infrared Thermal Imaging
IR thermal imaging detects subsurface moisture entrapment in the roofing assembly — wet insulation shows differently than dry insulation under thermal scan. The most precise non-destructive diagnostic for active leak source identification and early moisture mapping.
Full ASTM E2018 PCA Integration
Roofing inspection rolled into a full Property Condition Assessment per ASTM E2018-24 standard. Includes all building systems, structural, mechanical, electrical, plumbing, and site. The roof inspection becomes Section 5 of the PCR with CAPEX tables — the complete lender-grade due diligence document.
Foundation Elevation Survey (ZIPLEVEL®)
ZIPLEVEL® precision hydrostatic leveling across the building perimeter. Texas expansive clay soils make foundation settlement a co-occurring risk with roof concerns on older buildings. Bundle the roof and foundation inspection — one mobilization, complete picture.
Mold Assessment
Roof leaks produce interior moisture intrusion that produces mold. If the inspection identifies active or past water infiltration, a TDLR-licensed mold assessment identifies whether mold remediation is required — before it becomes a tenant, health, or liability issue.
Why the Source of the
Inspection Changes
the Inspection
The roofing industry's standard model is built on a conflict of interest: the company assessing your roof is the same company that profits if it needs work. That model functions acceptably for routine maintenance — but it breaks down in every situation where money is at stake.
The moment a roof inspection is being used for a purchase negotiation, an insurance claim, a lender package, a warranty dispute, or litigation support — you need a report from someone who has nothing to gain from any particular outcome. You need Imperial Pro.
Texas's TREC-licensed commercial inspectors are held to an independent standard that roofing contractors are not. Our licensure and liability attach to the accuracy of the report — not to the work that follows.

Five Roofs. One Contract.
One Vendor. One Standard.
Imperial Pro recently completed a five-property commercial roof inspection contract spanning the Texas Texaplex — Houston, San Antonio, Austin, and Dallas–Fort Worth assets, inspected within a unified timeline and delivered in a consistent, portfolio-formatted report.
Portfolio clients need consistency above all else. When you're presenting roof condition data to a capital partner, a lender, or an asset management committee, you need reports that speak the same language across every property — not five different contractors with five different formats and five different biases.
Imperial Pro provides multi-property inspection contracts with standardized scope, uniform methodology, and coordinated delivery. Single-roof or fifty-roof — the approach is the same.
Every Roof Inspection Proposal
Includes These Options
A roof inspection answers one critical question. These services answer the others — and every Imperial Pro roof inspection proposal includes them so you can scope the full picture in one engagement, on one mobilization, at one fee.
Full ASTM E2018 Property Condition Assessment
The roof is one section of a full commercial PCA. If you're buying, financing, or managing a commercial asset, you need the complete picture — not just the roof. A full PCA covers every major building system: structural, mechanical, electrical, plumbing, site, envelope, and roof. Lender-grade. 48-hour delivery.
Why it matters with a roof inspection: The roof inspection is already complete — adding a full PCA costs incremental time and fee, not a separate mobilization. Everything is in one report. One vendor. One due diligence document. Lenders require it. Buyers should want it.Foundation Elevation Survey (ZIPLEVEL®)
Texas expansive clay soils move. Commercial buildings age. Roof problems and foundation problems often co-occur on older buildings — because differential settlement causes structural movement that damages both the shell and the membrane above it. A ZIPLEVEL® precision elevation survey maps foundation movement to ±1/100 inch.
Why it matters with a roof inspection: If you're concerned about a commercial building's envelope, foundation movement is the structural question underneath the roof question. One mobilization covers both.Mold Assessment
Roof leaks produce interior moisture intrusion. Interior moisture intrusion produces mold. In Texas's humidity, mold colonization can establish within 48–72 hours of a water event. A TDLR-licensed mold assessment identifies whether active mold is present, documents affected areas, and defines the remediation scope — before it becomes a tenant complaint, a health issue, or a liability.
Why it matters with a roof inspection: When the roof inspection identifies evidence of past or active water infiltration, mold assessment answers the immediate follow-on question: what did that water do on the inside?Infrared Thermal Imaging
Infrared thermal cameras detect temperature differentials that reveal subsurface moisture entrapment invisible to the naked eye. Wet insulation stores heat differently than dry insulation — the camera maps this difference across the entire roof surface, identifying leak infiltration points, moisture migration paths, and saturation extent before visible damage appears.
Why it matters with a roof inspection: Any time a roof has suspected or confirmed leaks, thermal imaging locates the actual source — not just the interior manifestation. This changes the repair scope and the cost estimate significantly.Sewer Scope Inspection
Commercial properties with aging drain systems — particularly those with roof drains tied to interior plumbing stacks — benefit from sewer scope inspection at the same mobilization. Camera inspection of main drain lines identifies root intrusion, pipe collapse, or material deterioration before it causes overflow events or regulatory compliance issues.
Why it matters with a roof inspection: Roof drain systems on older commercial properties often connect to interior stacks. A single mobilization covers the drainage system from roof surface to municipal connection.Wood Destroying Insect (WDI) Inspection
Termite activity is not limited to residential properties. Commercial buildings with wood framing, wood structural members, or wood blocking in roofing assemblies are susceptible. On commercial properties with flat roofs, wood blocking at parapet walls and roof edges provides termite harborage that is difficult to detect without a licensed WDI inspection.
Why it matters with a roof inspection: Wood blocking in the roofing assembly is exposed to moisture and is a common termite harborage point. Bundle WDI inspection with the roof inspection for complete biological risk assessment.Commercial Roof Inspections
