Crazing on Single-Ply Roofing

Crazing is a network of fine surface cracks. On a single-ply roof, similar-looking conditions can have different causes and may affect only the surface or indicate broader material deterioration.

Inspect before selecting a repair

Record the membrane type and age if known, the location and extent of the cracking, seam and flashing condition, previous repairs, drainage, and evidence of moisture. Photograph representative and severe areas. Have uncertain membrane damage evaluated before applying a coating that could conceal the 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.
