Flat Roof Coating Project Planning

“Flat roof” describes roof slope, not the roofing material. Identify whether the roof is built-up roofing, modified bitumen, single-ply membrane, spray polyurethane foam, metal, concrete, or another assembly before selecting products.

Identify the roof system and drainage

Document the membrane or substrate, roof age if known, previous coatings and repairs, seams, penetrations, perimeter details, drainage paths, and areas where water remains after rainfall. Investigate wet materials and unresolved leaks before coating preparation.

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.
