Moisture Detection Before Roof Coating

A coating should not be used to conceal wet roofing materials or unresolved water entry. Moisture investigation helps define repair limits and determine whether the roof is a candidate for coating.

Choose an appropriate investigation

Review leak history, interior observations, roof condition, drainage, seams, penetrations, previous repairs, and available construction records. Depending on the assembly and project risk, an experienced roofing professional may recommend non-destructive moisture surveying, test cuts, or other verification. Record the method, locations, results, and repair disposition.

Confirm compatibility and current instructions

Review the current Lexis product data and safety data for every proposed cleaner, primer, sealant, reinforcement material, and coating. Confirm that the products are compatible with the existing roof and with one another. Complete any required adhesion testing on the actual roof before ordering the full project quantity.

Define the work before ordering

Document preparation, repairs, detail treatment, application method, coverage or film-thickness requirements from approved product data, weather limitations, safety responsibilities, and exclusions. Contractors should include these items in the written scope. Building owners doing their own research should use the same checklist when comparing options.

Ask Lexis about product selection

Send the roof type, approximate area, current condition, existing coatings or repairs, photographs, and project location through the Lexis contact page. These details help narrow product choices without assuming that one system fits every roof.
