Dealer/Contractor Member

When an employee of an Affiliate member becomes certified as an LPI Master Installer, the company automatically moves from the Affiliate category to our Dealer/Contractor category. Or, when your company joins the LPI, if you have an employee who is already a Master Installer or a Master Installer Designer, you will be placed in the Dealer/Contractor category.

LPI members not providing the required lightning protection system certifications are deemed “PROBATIONARY” and are noted as such on the LPI website.
