In 1959, at age 16 Robert C. Gueriera, Sr. took a neighborhood roofing business over from his father, Charles Gueriera.  Robert then took a business that had predominantly worked in the Overbrook section of Philadelphia and grew it significantly.

Specializing in 4 Ply BUR Roofing Systems on mostly residential homes, Robert quickly became a master mechanic and skilled businessman.

The business office and shop were moved to Broomall by the mid-1970s.  This move enabled the business to expand while still focusing on the low slope (flat) industry.

Recently the business has expanded even more, and we have moved to West Chester, PA.  This has allowed us to concentrate our interests on all types of low slope applications both industrial and commercial.

Our single-ply certifications which include EPDM and TPO are through the well-respected Carlisle/Syntec Company.  Our Built-Up and Modified Bitumen Systems are certified through the GAF Corporation.  Our training and certification with these strong manufacturers, enables us the opportunity to issue an NDL (No Dollar Limit) Warranty through the manufactures for up to 20 Years.
