Brandon was great to work with and offered solutions to logistics we needed handled, specifically removal of a pool solar system on one side of my roof. Also, Tri Valley Roofing was able to quote removal and reinstallation of my electrical solar system under a single contract. Coordination of the services was perfect including adding some trim pieces to provide a clean edge between the roof line and stucco siding. Five Stars.

I wanted to thank Mr. David Hahne for his professionalism and customer focus in responding to my…read morerequest for an estimate on new gutter installation. His estimate was the lowest I had received however I went with another business through no fault of Mr. Hahne. I had asked for the gutters to be painted with my trim color which unfortunately this business does not do. Mr. Hahne showed me color samples which were very close. While I did not experience his work, I have no doubt the customer would be satisfied.

My husband had open heart surgery a few weeks ago and the idea of roofers and gutter guys seemed overwhelming. David handled everything and his crew was professional, congenial and so easy to be around. The new gutters look beautiful and every angle was carefully crafted.

This an update to a wonderful, five-star rating that I provided to Wonderlin in 2022 after they put…read moreon our new roof and added solar provided by their sister company, Synergy Energy in Livermore. As any long time California resident knows, we don't get a lot of rain compared to other areas of the country. Because of climate change, we have started experiencing atmospheric river storms as witnessed in the last few weeks. We experienced a leak during the week between Christmas and New Years and when I called their office, I learned that they were closed until Monday, January 5. Well to my surprise. I received a call back from their office asking about the severity of the leak and whether I needed immediate help or could it wait until they had everyone back to work on the 5th. I had a bucket collecting water and the leak was small enough that I decided it could wait. On the 5th, I received a call back from the office asking if they could send two repair people that afternoon to inspect and repair the issue. I was not home but my wife was, and she said that the gentlemen were prompt and thorough and explained what they saw and what did to correct the leak. I am not writing this as a novice to the problems in the construction industry, I am now retired but worked 40+ years in the window and door portion of the industry from owning my own company and working in sales for a billion-dollar wood window company (Marvin Windows and Doors). If anyone knows of Marvin, they are a company that prides themselves in producing one of the best wood windows in the industry as well as providing exceptional service. Well, Wonderlin is right there with them. I will continue recommend them to anyone looking for a new roof and not having a lot of issues to worry about.

I really enjoyed working with this family run business.

When we noticed a leak in our home, it was recommended that we have first have our gutters cleaned and checked. A good friend recommended Jeff. Jeff returned my call promptly.

During the job, I paid an additional $200 in cash requested by the technician on site when he said some additional scope wasn't included in the $1,200 project.

I asked for documentation and clarification on their accounting, but that was never provided. Communication became focused on collection and lien warnings rather than investigating the payment issue. I was pretty shocked how aggressive they were in their phone calls and emails. I recommend that customers keep detailed records and receipts for any work done with this company.

Apparently, this is the first time they have encountered this installation in 15 years. The added complexity drove up the cost, but that's only fair. Also, after they removed the staples, they remounted the screens with screws, so the next time they can be removed and replaced easily. We got an upgrade. Other things of note - they were both very professional and friendly and they left the job site cleaner than when they arrived. Great job!!
