Describe the exposure
Give the roofer the property location, nearby saltwater, prevailing weather exposure and any history of rust or repeated repairs. Avoid treating a broad label such as coastal grade as a complete specification. Request identification of the project conditions and the documents used to select the roof assembly and its accessories.
Ask about concealed attachment
A clean-looking tile surface cannot show the condition of every fastener below it. Discuss how concealed components can reasonably be evaluated during planned repairs, and which areas remain unobserved. Record the limits of the inspection so the absence of visible rust is not mistaken for a complete attachment assessment.
Review compatible materials
Have the contractor identify proposed metals, coatings and fasteners together. Corrosion protection is a selection issue for the complete connection, not simply a preference for a familiar product name. Where components touch or drain onto one another, ask the manufacturer or design professional to confirm compatibility for the particular assembly.
Check local requirements at the right time
Coastal provisions differ by jurisdiction and can change between code editions. FRSA’s discussion of Florida corrosion requirements illustrates why the project team should verify the adopted edition and local interpretation. Request a written specification for the actual repair or reroof date, rather than relying on an undated internet detail.
Make inspections actionable
Ask for photographs showing the location and extent of visible corrosion, loose components or staining. Separate cosmetic observations from concerns requiring further investigation. Agree which items need prompt repair and which can be monitored, with a reason for each decision. Keep component identification and repair history together for the next coastal maintenance visit.
