We specialize in a wide range of roofing projects, servicing Homeowners Associations, Multi-family Residential, Commercial, Industrial, Medical Facilities, Schools, and more.

As the baby sister, Alta Roofing & Waterproofing benefits greatly from the two decades plus of acquired knowledge and expertise of its roofing family. It all started in 1989 when Dmitri Triphon founded Adco Roofing. Adco was established with an emphasis on providing its clients with excellent service, high quality workmanship and the best products available on the market.

Although just founded in 2014, Alta Roofing & Waterproofing already knows what it takes to service our customers. Our mission is to raise the bar on customer service in San Diego County.

Alta represents the final puzzle piece to California to provide the best border to border service throughout the state. With each company focusing in on a specific region, Alta has Southern California covered.

If you have experienced our service from any of our sister company’s, you will receive the same service at Alta that you have come to expect. If you have not worked with our family before, give us a try, we promise that you will receive the best service in the industry.
