What Are Elastomeric Roof Coatings?

Elastomeric roof coatings are fluid-applied products formulated to create a flexible film. The term covers multiple product chemistries and does not by itself establish compatibility, required thickness, service life, or suitability for a particular roof.

Start with the existing roof

Identify the roof substrate, condition, seams, penetrations, repairs, existing coatings, drainage, and signs of moisture. Review the exact product's current technical data for compatible surfaces, preparation, application conditions, coverage, and system components.

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.
