Commercial Roof Inspection in Houston

Who this is for

Property managers with a portfolio and a maintenance budget to defend. Facility managers who need a condition record before a capital request. Building owners weighing repair against replacement. Buyers doing due diligence on a commercial property. Anyone whose insurer, lender, or board has asked for documentation of roof condition.

The common thread is that the decision is rarely urgent and almost always has to be justified to somebody else. That is why documentation matters more here than it does on a house.

Low-slope roofs fail differently

A residential roof sheds water. A commercial low-slope roof manages it, and that distinction drives everything the inspection looks at.

Seams and laps. On single-ply systems the field membrane is rarely the problem. The seams between sheets are, and so are the details where the membrane is welded or adhered around anything that penetrates it.

Terminations and flashings. Where the membrane meets a parapet, a curb, an expansion joint, or a wall. Base flashing pulling away at a parapet is one of the most common findings on any Houston low-slope roof.

Penetrations. HVAC curbs, exhaust fans, vent stacks, conduit, gas lines, satellite mounts. Every one is a hole in the roof that something is supposed to be sealing, and every one is a place a maintenance contractor may have stepped, drilled, or improvised.

Drains, scuppers, and ponding. Blocked drains are the single most preventable commercial roof problem in this city. Standing water adds structural load, accelerates membrane degradation, and hides the defect underneath it. Water still sitting on a roof more than a couple of days after rain is a finding in its own right.

Surface and substrate condition. Blistering, splitting, shrinkage at corners on older single-ply, alligatoring on built-up, granule loss on cap sheets, and soft spots underfoot that indicate saturated insulation below the membrane.

The systems you will hear named

Knowing which system is on your building changes what you should expect to hear.

TPO — thermoplastic polyolefin, a heat-welded single-ply, usually light-colored and reflective. Common on newer construction. Failures concentrate at weld seams and at the terminations.

EPDM — a synthetic rubber single-ply, typically dark, either ballasted, mechanically fastened, or fully adhered. Durable in the field; the seams and the flashing details are where age shows.

Modified bitumen — asphalt-based sheets in multiple plies, torch-applied, hot-mopped, or self-adhered. Failures show at laps and at the base flashings.

Built-up roofing (BUR) — the traditional multi-ply asphalt-and-felt system with a gravel or cap-sheet surface. Long-lived when maintained, and when it fails it usually does so at the flashings and at aged surfacing.

Metal panel — failures at fasteners, at panel seams, and at penetration curbs rather than across the panel itself.

A useful survey also notes the insulation and cover board condition below the membrane, since saturated insulation is frequently the real cost driver in a replacement, and any infrared or moisture survey findings where that method was used to map wet areas without cutting the roof open.

Documentation is the deliverable

On a house the deliverable is usually an answer. On a commercial building it is a record.

A useful commercial inspection produces a written condition summary, photographs keyed to locations on the roof, findings separated into immediate leaks, active deterioration, and deferred maintenance, and an indication of remaining service life. That is what a capital request, a board packet, an insurance file, or a due-diligence review can actually be built on.

Two things worth confirming before the visit rather than after. First, whether a formal written report is included or is a separate paid deliverable — it is frequently the latter, and assuming otherwise costs you a second appointment. Second, whether your manufacturer warranty requires documented periodic inspection to stay in force. Many single-ply warranties do, and a lapse in the maintenance record is a common reason a claim gets refused years later.

What we are, plainly

We are a referral service. We connect you with one independent insured local roofing professional. We do not perform inspections, we do not produce reports, we do not administer warranties, and we are not the contractor.

Verify the contractor's insurance, their experience with your specific roof system, and the written scope before authorizing anything. Commercial roofing is specialized by system — a company excellent on shingles is not automatically the right one for a 60,000 square foot TPO roof.

Request a commercial roof inspection

Call, or use the form. The details worth having ready: building type and approximate square footage, the roof system if you know it, the age of the roof, whether there is an active leak, roof access arrangements, and whether you need a formal written report.

The local pro confirms availability and agrees the scope with you before attending.
