Thank you for coming to PetersenDean

Since I started PetersenDean 30 years ago, we have fulfilled our mission of delivering world-class roofing and solar power systems at the best possible value for our customers. Now, more than ever, I believe that solar power should be accessible for all Americans. In fact, this year, an independent review of California Solar Initiative (CSI) data shows that for the last 12 months PetersenDean has achieved the most affordable solar installation price. The Solar4America campaign is my concept to deliver transparency in solar pricing and drive down the costs of solar power. No “financial magic” or “accounting tricks”; Just a fair price and commitment to quality installation. We look forward to earning your business.

Important Letter from
the Owner

Jim Petersen

Quality and customer satisfaction are at the forefront of everything we do

(Update to my last message).

To Our Valued Customers:
I would like to update you since my last message. Two and a half years ago we moved away from foreign made products and transitioned to American made products. We were having quality, delivery and follow through issues with our overseas vendors. Buying only American was one of the best choices I have made in my professional career. American made products cost a bit more but the quality is much higher and the response from our customers has been overwhelming.

I thought we would lose out on a few sales because we might not be as price competitive but the opposite happened. It turned out that I wasn’t the only one who wanted to support American workers and their families. The response made me think of a quote I heard “when was the last time you bought something cheap and were happy with it”. Now two and a half years later we are the largest installer of American made solar systems in the United States. Not only did our customers applaud our decision, they told their friends and families about us. Offering high quality American made products in addition to our Senior, Veteran & Median income discounts has created a substantial backlog. That backlog has generated some delays for our customers and prompted me to write the previous letter. Well we are happy to say after many long nights and weekends we have caught up and installing faster than ever.

If you are looking for a new roof or solar system for your home, we would love the opportunity to earn your business. Our credentials prove that quality and customer satisfaction are at the forefront of everything we do here at Solar4America/PetersenDean. We are the only NHQ Certified roofing and solar power firm in the country. We have an A+ rating with the BBB. We have earned twenty Golden Gate Partnership awards from OSHA (there is not one other roofing or solar power firm that has ever been awarded one). We are Master Elite Certified Installers of all of our manufactured roofing products. We have been awarded the Nation’s best Roofing and Solar Power installer TWICE in the last five years.
You can still reach me at the link below. I would love to hear from you. I would like to thank you for choosing PetersenDean and American made (only) products.

With my most deepest respects,
Jim Petersen

Founder, PetersenDean Roofing and Solar Systems.
