Roof Ponding and Coating Project Planning

Ponding describes water that remains on a roof after rainfall. Recurring standing water can indicate drainage, slope, deflection, blockage, or roof-assembly problems that should be understood before coating.

Document the drainage condition

Photograph water locations and drainage paths after rainfall, record how long water remains, and inspect drains, scuppers, gutters, seams, flashings, and nearby repairs. Do not assume a coating will correct drainage or structural conditions. Review the exact product's current limitations for the documented service condition.

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.
