Describe the complete connection
Ask the contractor to identify the tile or accessory, substrate, fastener designation and installation method for each connection type. Product approvals can distinguish attachment options rather than treating every screw or nail as equivalent. The reviewed Ludowici acceptance is one example. Have the project team verify the current applicable document and record any approved substitution before the replacement hardware is used.
Evaluate the environment
Salt exposure, persistent wetness, condensation and construction conditions influence corrosion risk. Simpson Strong-Tie’s selection guidance evaluates the service environment before choosing coatings and base materials. Our practical recommendation is to give the supplier the building location and assembly information, rather than asking only for an exterior-rated screw. Connections hidden beneath tile deserve the same specification discipline as visible metalwork.
Check materials that touch
Treated wood can introduce chemicals that affect metal components, and wet contact between dissimilar metals can accelerate corrosion. Confirm compatibility among the wood treatment, fastener and connected metal. Stainless steel is not a guarantee against corrosion. Record the supplier’s recommendation with the roof’s connection schedule.
Keep substitutions traceable
Create a short connection schedule before delivery: location, specified component, supplier and approved alternative if one exists. Ask the crew to retain package labels and report shortages before substituting. This is a project-management recommendation intended to make review practical. At the inspection checkpoint, compare the installed connection with that schedule and resolve mismatches while the work remains visible.
