Founded in 2003, ADG Roofing started in a small home office in the San Fernando Valley. Owner Dotan (David) Swisa has spent 8 years in the construction industry. He started as a roofer, gaining insights into roofing for residential and commercial properties. He then joined a general contractor, tackling a range of home improvement tasks. After working for a subcontractor, David realized the excessive fees customers faced due to the “middle man” role. He aspired to establish his own company, collaborating with his own team, and most importantly, offering honest pricing. It was five years ago that he found his true passion in roofing. This led him to create ADG Roofing and claim it as his own. ADG is proud to have its own roofing team and perform all work in-house. Still a small, friendly roofing company, ADG is growing strong and proudly serves as a local family roofing provider.
David and his team at ADG Roofing bring significant expertise to the roofing industry. Over the past 8 years, he has worked and managed projects in both residential and commercial roofing. His extensive knowledge and professionalism enable him to serve you effectively.

Recommended Customer Reviews
This company is great! We own a couple of buildings in the Los Angeles area and ADG Roofing did several repairs, outstanding work!
They were very honest and competitive and had great pricing.
I would use them again when and if we need any other repairs or a new Roof. I would also recommend them to everyone.
Sarah S.I used ADG and they had done a much better job than anyone I have ever used or recommended. They are honest and their prices are very reasonable. As a Realtor, it's very hard to find great and honest people in this industry and I'm glad I found ADG. Even when I get my own materials, they are always there to tell me if I'm getting a good deal or not. 5 stars.
Des B.David and his team were incredibly friendly, well versed, knowledgeable and professional. When I requested a quote for the roof he came though, on time and within price range. I will be getting my roof done in the near future and can't wait! Will post update soon on the outcome!!kudos David!!!
Ron P.These guys were awesome. Came prepared and on time, were very friendly and clean. Finished very fast and did a great job.
Professional, friendly, and just a wonderful team to work with.
David you are great! Thank you.
They replaced the wood under my tile roof. After leaving, my husband went up to check the roof and found there were a few broken tiles they had not replaced. I'm not sure if they were broken before or if they had broken them putting them back up. Needless to say I called them and they were out the next day with the replacements no questions asked.
These guys did a wonderful job. They were very comfortable to work with. They had a competitive price and I'm so happy I chose them in the end. Thank you very much ADG!
Eric A.When we bought our house last year, the inspector we hired told us that the roof had two layers and that we can add another layer when the time came if we needed too. I wish I got a second opinion and did some more research because I learned that the city only allows two layers until needing to replace the entire roof. I did not want to take a risk with water damage knowing the roof was not in the best shape. We knew the time was coming close and we needed to re-roof so I began to get a few estimates. I learned after the first estimate that we not only had two layers but we had four and the bottom layer was wood. This was the worst thing because we found out we would need to spend a lot more removing all the layers and adding new plywood.
When ADG Roofing came out they were very punctual and professional. They were the 3rd company to come out. The roofer took pictures and showed us how many layers there were and how bad of shape our roof was in. The price they quoted was in my opinion, not the cheapest but it also was not the most expensive. What set this roofer apart from others is the detailed explanation and expertise that I felt the roofer had compared to the others. We scheduled the job and the job went very well. They came out on time and after a week of work they finished the job according to schedule. I knew I made the right decision choosing this company when I saw how professional they were and paid close attention to the details. We couldn't have made a better decision. I highly recommended this company.
Great roof job from these guys. We got a cool roof of shingles and couldn't be happier. Thank you.
We just got the work done on our roof, and I'm very satisfied. They did a good job on it, and I think it looks nice. I would haven given 5 stars, but one of the workers broke one of our sprinklers when they were walking across my lawn. I pointed it out to them and they did replace it.
