Commercial Roof Inspection
Commercial Roof Inspection Services in Southern California
Documented inspections for property managers and owners across the LA Basin, San Gabriel Valley, and Inland Empire, so roof decisions are driven by data, not surprises.
A commercial roof inspection is a documented, point-by-point assessment of a roof's condition, drainage, flashings, penetrations, and substrate, delivered as a written report with photos and budget projections. It is one of the largest and most expensive assets on any property, and the easiest to ignore until it fails. A regular, documented inspection is how disciplined property managers turn an unpredictable liability into a planned, budgeted line item. HP Roofing Pro provides thorough commercial roof inspections across Southern California, with written reports built for the way real asset-management teams actually make decisions.
Serving Property Owners Across Southern California
We inspect commercial roofs throughout the San Gabriel Valley, the LA Basin, the Inland Empire, Orange County, and San Diego County, traveling from our Alhambra headquarters with a full crew. Southern California roofs face a specific mix of stresses: Santa Ana wind events that lift seams and edge metal, coastal moisture that works into flashings and laps, and long summer heat cycles that age membranes and coatings. Our inspections are built around those local conditions, so the report reflects what your roof is actually up against, not a generic checklist.
When to Schedule a Roof Inspection
Annual & semi-annual (routine)
Twice-yearly inspections, typically spring and fall, catch small failures while they're still inexpensive repairs. Routine inspections are also the single best way to extend the service life of a commercial roof and protect warranty coverage.
After a storm or high-wind event
Wind uplift, hail, and debris cause damage that isn't visible from the ground. A post-storm inspection documents new damage promptly, important both for repairs and for any insurance claim.
Before a purchase or lease (due diligence)
A pre-purchase inspection gives buyers an independent read on remaining roof life and likely near-term costs before closing, often the difference between a confident deal and an expensive surprise in year one.
What We Inspect - Our 12-Point Assessment
Every inspection follows the same disciplined checklist, so your reports are consistent and comparable over time.
Membrane & surface condition
Splits, blistering, granule loss, UV degradation, and coating wear across the field of the roof.
Seams & laps
Open or lifting seams on TPO, PVC, and modified-bitumen systems, the most common entry point for leaks.
Flashings & terminations
Wall, curb, and edge metal flashings, counter-flashing, and termination bars for separation or failure.
Penetrations
Pipe boots, vents, conduit, and HVAC curbs sealed and watertight.
Drainage & ponding
Drains, scuppers, and internal gutters clear; documenting ponding areas that shorten roof life.
Parapet walls & copings
Cap sheet, coping joints, and wall transitions for cracking and moisture intrusion.
Skylights & curbs
Glazing, gaskets, and curb flashing on skylights and smoke hatches.
Rooftop equipment
HVAC units, condensate lines, and equipment supports for damage and leaks they cause.
Fasteners & attachment
Backed-out fasteners, billowing, and wind-uplift risk on mechanically attached systems.
Insulation & substrate
Soft spots and trapped moisture indicating saturated insulation below the membrane.
Sealants & caulking
Aged, cracked, or failed sealant at transitions and metal joints.
Interior & deck signs
Ceiling staining, deck deflection, and other interior evidence of active or historic water intrusion.
What You Receive
An inspection is only as useful as the report behind it. After every assessment you receive a written report designed to go straight into your records and your budget conversations:
- photo_cameraDate-stamped photos of every area of concern, so issues are documented, not just described.
- checklistA condition summary for each of the twelve inspection points, in plain language.
- priority_highPrioritized recommendations, what needs attention now, what to watch, and what can wait.
- paymentsBudget projections so you can plan repair, restoration, or replacement spending across fiscal years.
When a report flags an active problem, we can move straight into a targeted commercial roof repair, and if the leak is already active, our emergency roof leak response stabilizes it the same day. Because the report is documented and date-stamped, it also provides the inspection record most manufacturer and workmanship warranties require, including the leak-free warranty on our RainArmor restorations.
Our inspection and reporting process has been applied to properties across LA County and the Inland Empire, from coworking and creative office space to large-format industrial buildings exceeding 200,000 square feet, including a 280,000 sq ft manufacturing plant in Alhambra and the historic CTRL Collective building in Pasadena, where manager Tim Cason chose a documented restoration over a full tear-off. That work is part of why we hold a 5.0 rating on Google. As a CSLB-licensed contractor (#1043546), GAF CoatingsPro, and Owens Corning Preferred Contractor, we document what we find and stand behind what we recommend. You can review documented outcomes in our project portfolio.
From Findings to Action: Repair, Restore, or Replace
An honest inspection should end with a clear recommendation, not a sales pitch. Our written report sorts findings into three tiers, so you know exactly what your roof needs and why.
Repair
Localized failures, open seams, flashing problems, and isolated leaks, addressed with a targeted repair while the rest of the roof still has useful life.
Restore
When the membrane is aging but the deck is sound, a RainArmor restoration system seals the roof over the existing surface, with no tear-off, typically at 40 to 60 percent of the cost of a full replacement.
Replace
When the substrate is failing or the system is genuinely at the end of its life, replacement is the right call, and we will tell you so plainly.
The roofing industry defaults to tear-offs because they are the most expensive option. We do not recommend replacement when a repair or restoration will protect the building and the budget. That is the whole point of an honest assessment.
How Inspections Fit Your Maintenance Program
Inspections deliver the most value when they feed a program rather than sit in a drawer. The findings from each assessment become the work plan for the next service visit, minor repairs handled proactively, drains cleared before the rainy season, and small failures fixed before they become interior damage.
That loop, inspect, document, maintain, re-inspect, is exactly what a commercial roof maintenance program is built around. For properties enrolled in maintenance, scheduled inspections are included, and the same crew that knows your roof handles the follow-through.

How often should a commercial roof be inspected? add
For most commercial roofs we recommend a documented inspection twice a year, typically spring and fall, plus an inspection after any major storm or high-wind event. Roofs under warranty often require regular inspections to keep coverage valid.
How long does a commercial roof inspection take? add
Most inspections take one to three hours depending on the size of the roof, the number of penetrations and rooftop units, and access. You receive your written report shortly afterward, not weeks later.
What do I receive after the inspection? add
A written report with date-stamped photos, a condition summary for each area we check, prioritized repair recommendations, and a budget projection so you can plan capital and maintenance spending with your ownership or asset-management team.
Do you inspect roofs you did not install? add
Yes. We inspect commercial roofs of any age and system type, TPO, PVC, modified bitumen, built-up, and coated roofs, regardless of who installed them.
Can an inspection help with a pre-purchase or due-diligence review? add
Absolutely. A pre-purchase roof inspection gives buyers and property managers an independent assessment of remaining roof life and likely near-term costs before closing, one of the most valuable uses of an inspection.
Will an inspection keep my warranty valid? add
Many manufacturer and workmanship warranties require documented periodic inspections and maintenance. Our reports provide exactly the documentation most warranties ask for.
What does a commercial roof inspection cost? add
Cost depends on roof size and complexity. For properties already on one of our maintenance programs, scheduled inspections are built in. Call 909-521-1285 and we will give you a straight answer for your building.
