Alta Roofing And 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.

We are servicing commercial, office buildings, home owner associations as well as industrial roofing systems.

We are a fully staffed, licensed, financially strong contractor and a leader in our industry. We can perform roof repairs, preventive maintenance, complete re-roofs and more.


Alta Roofing & Waterproofing already knows what it takes to service our customers.

We are raising the bar on customer service in San Diego County.

I just had a roofing job completed by Alta Roofing and these guys did a fantastic job. Nubia was very professional over the phone and made scheduling easy, even sent a reminder email of the inspection date and time. When Greg came out to inspect the roof, he was super friendly with a big smile. He took pictures and noted every problem issue on the roof. He then gave me an honest recommendation of what should be done. I highly recommend Alta Roofing for being an trustworthy company and would do business with them again.
