P91 Commercial Roof Inspection and Moisture Detection

Find trapped moisture before it becomes a structural bill.

Our standardized inspection and detection process identifies moisture trapped within a commercial roofing system before it causes widespread damage, insulation deterioration, mold, or costly structural repairs. Moisture detection is especially valuable for TPO, PVC, EPDM, modified bitumen, and other low-slope commercial roofing systems. By identifying wet areas early, building owners can make informed decisions about targeted repairs versus larger roof replacement, potentially extending the life of the existing roof. Our service includes roof inspection, moisture scanning, identification and mapping of suspected wet areas, photo documentation, assessment of potential leak sources, and repair recommendations.

Systems we install & service

The right system for the building — not the other way around.

Commercial roofing isn't one product. We assess deck type, slope, insulation, drainage, foot traffic, and budget before we recommend a system. Here are the assemblies we install and service most often across Greater Houston.

Single-ply membranes
Single-ply membranes

TPO, PVC, and EPDM — the workhorses of low-slope commercial roofing in Texas. Mechanically attached, fully adhered, or ballasted depending on the building.

Modified bitumen
Modified bitumen

SBS and APP asphalt systems installed via torch, cold-adhered, or self-adhered methods. Proven, repairable, and a strong fit for re-roofs over existing built-up assemblies.

Metal roof systems
Metal roof systems

Standing seam, exposed-fastener, structural and architectural metal. Long service life, hail-resilient, and a clean look for office, retail, and industrial.

Spray polyurethane foam (SPF)
Spray polyurethane foam (SPF)

Seamless sprayed insulation and waterproofing with a protective coating. Excellent for restoring aged decks without a full tear-off.

Roof coatings & restoration
Roof coatings & restoration

Silicone, acrylic, polyurethane and aluminum coatings extend the life of an existing membrane and reflect Houston heat — often without disrupting tenants.

Built-up roofing (BUR)
Built-up roofing (BUR)

Traditional tar-and-gravel multi-layer assemblies. We service, repair, and re-roof BUR systems already in place across older Houston commercial properties.
