About Us






Paragon Roofing Co. is a full-service commercial roofing company which has been performing installation, repairs and maintenance under the same ownership for thirty years..


We pioneered the use heat-welded APP modified bitumen for flat roofs in Southern California beginning in the 1980s. When installing APP systems, Paragon uses absolutely no mastic (aka Henry's, plastic roof cement, etc.); every penetration through the roof is sealed with multiple layers of the roofing membrane itself. This significantly reduces the opportunities for leaks and the cost of maintenance over the roof's service life.


APP systems are available with 12-, 15- and 20-year non-prorated manufacturer's warranties which cover the materials and workmanship.


We also have three decades of experience with a wide variety of shingle, tile and metal roofing systems.


Paragon has partnered with other local vendors who provide top-quality roof-related components such as custom sheet metal (essential for properly flashing unusual rooftop equipment, fascia or other trim, etc.)


We can also provide detailed forensic analyses and reports for building owners or managers regarding specific issues, as well as a general assessment of existing roofs.


Our corporate mission is simple:


Paragon Roofing provides top-quality roofing work at fair prices with the same level of workmanship and customer service we would want if the work were being performed on our property.
