Roof Systems

Older roofs need a measured next step

Multi-ply and retrofit assemblies need their own inspection logic. Modified bitumen has layered reinforcement and surfacing that can conceal a split or moisture path. A built-up roof may include several plies over insulation, so a surface patch does not answer whether lower layers remain sound. On metal, movement at clips, fasteners, laps, and perimeter details deserves attention; a metal roof retrofit is considered only after the existing panels and support conditions are reviewed.

Coatings depend on preparation and drainage

A coating can extend a suitable roof's service life only when the existing surface, seams, drainage, and adhesion support the specified system. Silicone roof coatings and acrylic roof coatings are not interchangeable answers to ponding or wet insulation. Spray foam also depends on a sound substrate and a protective coating, with drainage and surface preparation assessed before application. We define repairs and preparation first, then explain where a coating is appropriate and where replacement or another assembly better addresses the observed condition.

Choose by condition, not label

Longview's airport climate normals reach about 94 degrees for a July daily high, while the area also has documented hail and tornado exposure. The recommendation comes from the building inspection, available roof records, and any approved testing. A roof near Longview Business Park may face different access or operational needs than a building near Downtown or LeTourneau. We use records, field observations, and any approved test to select a compatible repair. Owners can share the roof plan, warranty, repair history, access limits, and the question they need answered.

A commercial roof inspection records the field details needed before material selection. For a Longview roof service visit, include the building plan, repair history, and any warranty records.

Commercial Roofing Questions

Can a roof type be identified from a photograph?

A photo may show a visible surface or edge, but it may not reveal attachment, insulation layers, or a later overlay. We compare field details with submittals and warranty records before specifying a compatible repair.

When is a coating a reasonable option?

The existing roof must be dry enough, stable, properly drained, and suitable for the selected coating. We inspect seams and flashing first, then define preparation and repairs required for adhesion.

Do EPDM and TPO use the same repair materials?

No. Their seam and flashing methods differ. We verify the installed membrane and product requirements, then use a repair detail designed for that assembly instead of substituting material by appearance.

What if roof records describe a different system than the field shows?

We mark the discrepancy by roof zone and compare visible edges, seams, and past work. If the difference changes material selection, the owner receives the evidence needed to resolve it before repairs proceed.
