[heading-style-h3]Is Your Commercial Roof a Candidate for Silicone Coating? Eligibility Checklist[heading-style-h3]

[heading-style-h4]What makes a roof worth evaluating for coating?[heading-style-h4]

‍

The first question is whether the existing roof can remain in service as part of a restored assembly. The membrane or surface must be sufficiently stable, attached, and repairable. Loose, severely deteriorated, or structurally unsupported areas require more than a coating layer.

Leak history matters. Active openings should be located and repaired, and the assembly should be dry enough for the selected system. Coating over trapped water does not remove the moisture or restore damaged insulation.

‍

‍

[heading-style-h4]Moisture must be mapped and corrected[heading-style-h4]

‍

A moisture survey, selective verification, or both may be needed to define suspect wet areas. Wet insulation and deteriorated materials should be removed and replaced according to the approved scope before coating proceeds.

The survey method and limits belong in the report. A dry-looking surface alone does not prove the assembly below is dry, while one anomalous reading does not prove the whole roof is saturated.

‍

‍

[heading-style-h4]Adhesion testing is a project-specific gate[heading-style-h4]

‍

The proposed coating must bond to the cleaned and prepared existing surface. Test patches or adhesion testing help confirm whether primers, cleaning methods, or other preparation are required.

Results apply to the tested surface and preparation. Different repairs, contaminants, coatings, or membrane areas may require separate review.

‍

‍

‍

‍

[heading-style-h4]Drainage and details still have to work[heading-style-h4]

‍

Coating follows the existing roof geometry. It does not create positive drainage by itself. Drains, scuppers, gutters, low areas, and ponding patterns should be assessed before the scope is approved.

Seams, flashings, curbs, penetrations, terminations, and edge details usually require cleaning, reinforcement, repair, or system-specific treatment. The field coating is only one part of the system.

‍

[heading-style-h4]What should the coating proposal explain?[heading-style-h4]

‍

‍

• Existing roof type and the areas included in the restoration.
• Moisture survey method, findings, verification, and removal scope.
• Cleaning, primer, adhesion testing, and surface preparation.
• Repairs at seams, flashings, drains, curbs, penetrations, and edges.
• Coating product, application requirements, measured coverage, and quality control.
• Written warranty terms, exclusions, inspections, and maintenance requirements.

[heading-style-h4]How Flat Roof Pros approaches coating eligibility[heading-style-h4]

‍

Flat Roof Pros treats coating as a condition-based restoration decision. Inspection, moisture review, preparation, repairs, adhesion, drainage, and the selected system must support the scope before a coating recommendation is made.

[heading-style-h4]Common questions[heading-style-h4]

‍

Can silicone coating stop an active roof leak?
‍Active defects should be located and repaired as part of a defined restoration scope. Coating the field without correcting the source is not a complete leak repair plan.

‍

Can silicone be applied over wet insulation?
‍Wet insulation and deteriorated materials should be identified and replaced according to the approved system. Coating does not dry or restore trapped wet material.

‍

Does coating fix ponding water?
‍No. Coating does not change roof slope by itself. Drainage defects and persistent low areas must be evaluated and addressed in the design.

‍

Does every old commercial roof qualify for restoration?
‍No. Some roofs need extensive correction or replacement because of moisture, attachment, substrate, drainage, structural, or detail conditions.
