Modified Bitumen Roof Coating Project Planning

Modified bitumen roofs vary by membrane type, surface, installation method, repairs, and previous coatings. Confirm the actual roof construction and current condition before choosing a coating system.

Inspect the membrane and details

Record open laps, splits, blisters, exposed reinforcement, granule or surface condition, flashings, penetrations, previous repairs, drainage, and signs of wet roofing materials. Separate membrane repairs from coating preparation and identify areas requiring professional evaluation.

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.
