Master Elite Certified Contractors

GAF Master Elite Certified Contractors

We are Master Elite Certified Installers for GAF Materials Corporation (Master Elite # ME07157), which means that only 2 of 100 roofing contractors can become authorized for Master Elite Installers by GAF.  This is not a “title” simply handed out to any roofing company who thinks they are qualified.  Being Master Elite Installers allows us to offer a complete 20 Year Non-Prorated Labor and Material Warranty on top of standard warranties. Lange Roofing holds an excellent record with the Better Business Bureau.

In addition to the great reputation that we hold with our customers, Lange Roofing Inc. also has an honorable relationship with our local supply houses such as Gary Hobart Roofing and Allied Supply.

For your protection, Lange Roofing Inc. is Licensed, Bonded, and Insured (Call for specific license details as every state, county and town have different license requirements).

Since 1950, Lange Roofing Inc. has been serving homeowners and builders in Northwest Indiana and Northeast Illinois with the highest quality workmanship.  Due to the number of years of service, Lange Roofing Inc. has had the opportunity to accumulate an upstanding amount of credentials.
