Commercial Roof Inspection

A slow leak on a flat commercial roof rarely announces itself until insulation is already soaked.

Our GAF Certified Plus inspectors document every membrane seam, drain, and flashing point so you know your roof’s real condition before it becomes a claim. Schedule a Free Commercial Roof Inspection

Watch How We Deliver Quality

Signs Your Commercial Roof Needs an Inspection

Ponding Water After Rain

Water sitting more than 48 hours on a low-slope membrane signals a drainage or slope problem that accelerates membrane breakdown.

Rising Utility Bills

Failing insulation or a compromised reflective coating lets conditioned air escape, driving cooling costs up during Houston's long summers.

Interior Ceiling Staining

Discoloration near HVAC curbs or penetrations usually traces back to a seam or flashing failure that's already let moisture into the deck.

What a Commercial Inspection Actually Covers

What Happens During a Commercial Roof Inspection?

We walk the full roof deck during every commercial roof inspection rather than relying on drone photos alone, since membrane seams and flashing details on a Houston low-slope roof need to be checked by hand.

✔ Seam and flashing integrity check on TPO, EPDM, and PVC membranes
✔ Drain, scupper, and gutter flow test to catch ponding before summer storms
✔ Moisture scan of insulation beneath the membrane where visible staining exists
✔ Written report with photos, delivered before any repair recommendation

Membrane Types & Houston Climate

How Often Should a Flat Commercial Roof Be Inspected in Houston?

Houston’s combination of intense UV exposure, high humidity, and Gulf storm activity puts more stress on a low-slope membrane than a moderate climate would.

We recommend a documented inspection twice a year — once before hurricane season and once in late fall — plus a follow-up after any named storm.

Common Questions About: Commercial Roof Inspection

How long does a commercial roof inspection take?

Most single-building inspections in Houston take 1–3 hours depending on roof size and the number of penetrations, HVAC units, and drains that need individual checks.

Do I need to be present during the inspection?

No. A property manager or facilities contact isn’t required on-site, but we recommend someone be reachable in case we find an active leak that needs an immediate decision.

Can a roof inspection be done while the building stays occupied?

Yes. Inspections are conducted entirely on the roof deck and don’t require access to occupied interior space, except for a brief check of ceiling tiles near known problem areas.

What’s the difference between a residential and commercial roof inspection?

Commercial inspections focus on low-slope membrane systems, drainage, and rooftop equipment penetrations, while residential inspections focus on shingles, valleys, and steep-slope flashing details.

Will ponding water always require a full roof replacement?

Not necessarily. Isolated ponding is often corrected with tapered insulation or added drainage at the low point, while widespread ponding across an aging membrane may point toward replacement.

How does Houston’s humidity affect commercial roof membranes?

Sustained humidity slows the drying of trapped moisture beneath a membrane, which can accelerate insulation breakdown and adhesive failure compared to drier climates.

Should I schedule a commercial roof inspection after every named storm?

We recommend it for any storm with sustained winds over 50 mph or hail, even if there’s no visible interior leak, since membrane punctures can go unnoticed for months.

Does a roof inspection affect my building’s insurance premium?

A documented inspection history can support lower premiums or faster claim approval, since it shows the roof has been maintained rather than neglected.

What’s included in the written inspection report?

You receive dated photos of each finding, a section-by-section condition summary, and a prioritized list of repair recommendations with no obligation to book work with us.

Can an inspection identify a leak that hasn’t shown up inside yet?

Yes. Moisture scanning and a close visual check of seams and flashing often catch a compromised area before it produces a visible ceiling stain.

How does UV exposure affect commercial roofs in Houston specifically?

Houston sees more high-UV days annually than many northern markets, which accelerates membrane brittleness over time — a reason reflective coatings are common on local flat roofs.

Is there a cost for a commercial roof inspection?

Achilles Roofing & Exterior offers a free inspection with a written report for Houston-area commercial buildings; any repair pricing is quoted separately after the findings are reviewed with you.
