(NFPA) Certified Skylight Installer (CSI) The CSI (NFPA) Certified Skylight Installer distinguishes itself by zeroing in on roof-mounted fenestration—unlike general roofing certifications or broad weatherproofing credentials. You’ll engage with flashing details, condensation control, and load-bearing calculations specific to skylights, rather than spanning multiple roof systems. This laser focus means deeper expertise in a specialized niche that general contractors often outsource.
