(MCA) Certified Metal Siding Installer (CMSI) Installers often overlook fastener spacing requirements in high-wind zones, costing them points on CMSI. The exam weighs thermal expansion calculations heavily—many rush through these without accounting for substrate materials. Flashing installation around penetrations trips up experienced candidates who skip the manufacturer specs. Proper underlayment sequencing and moisture barrier placement separate passing scores from borderline attempts.
