A-1 Advanced Coating & Foam Co.

A‑1 Advanced Coating & Foam specializes in commercial spray‑foam insulation and roofing solutions for South Texas properties. Based at 6610 FM 775, Seguin, TX 78155, the family‑owned company has been serving industrial and commercial facilities since 1982, offering a localized, hands‑on approach that keeps all work in‑house. Their core services include spray‑in foam insulation, spray‑foam roofing coatings, waterproofing and TPO roofing applications.

For roof projects, A‑1 applies a two‑component, closed‑cell polyurethane foam in densities of 2.5 lb, 2.8 lb or 3.0 lb, with the 2.8 lb system most frequently used because it meets warranty requirements while delivering higher compressive strength and self‑flashing capability. The foam can be sprayed to a thickness of one inch or more, allowing the contractor to create positive drainage, eliminate ponding water and increase the roof’s R‑value. It adheres to metal, modified, built‑up, concrete, shingle and rolled roofing, sealing flashings, penetrations, cracks and crevices in a seamless layer that also insulates interior spaces from extreme temperatures.

In addition to roofing, A‑1 provides spray‑foam insulation for walls and ceilings, using the same high‑quality closed‑cell foam to improve energy efficiency and moisture resistance. All work is performed by South Texas‑based staff, and
