"My home is about 47 yrs old and we discovered that there were concrete tiles with no plywood underpayment. In December last year, due to big storm & strong wind, I needed a roof repair. I had multiple contractors bid the job. Total of 6 qualified contractors provide me a quote for roof fixing. Sagi (project manager) from Apollo came to my house on Christmas Eve, performed a very thorough inspection and sent the report and quote a few days later. I did a ton of researches, thinking of installing the solar panels in the future. I asked the contractors to send me a quote for a full roof replacement. They all took the time to explain the various roofing methods and materials, price is very competitive. Apollo quote was not the cheapest one, but I liked Apollo payment method: No down payment, payment was splitted into 4 payments. Services: Tile removed, Shingles installation, plywood installation, gutter guard & attic vents installation. The entire job took 3 days (I had around 2100 sq ft"

We have been servicing California since 2002, building a brilliant reputation on integrity, communication, and excellent work. We specialize in any type of gutter work, from cleaning and repairs to replacements We get the job done right, no matter what it takes. Have one of our certified gutter specialists come do a free estimate today. Join our elite group of satisfied customers!

"We contacted Sunshine Gutters after seeing the outstanding reviews on Angie's List. We met with Zack Allen, the sales rep, two or three times in June 2025. We initially were hoping for only new gutter guards, but Zack showed us the gutters were currently have were not installed to ideally drain water and recommended new gutters with their gutter guards. My husband, Tim, wanted to ensure they could make/provide us with creaseless gutters (no horizontal lines/creases), which is what we currently have. Zack said that could be done, but we would not be provided a warranty, which was a risk we were willing to take. I made the 10% deposit on 7/2/25, and the gutters were delivered the week of 7/7/25. Tim immediately noticed that the gutters were too large for our home and not the size of the gutters that we currently have. The gutters also have a crease in them, and we were told they would not have one. Zack came to our home, Tim and I both met with him, we did the measuring together, and he acknowledged that the gutters made are too large for the home. We were also told at that time that they had to make the gutters with the one crease, and we pretty much had to just accept it. We were not told this before them being made. He assured us that if an acceptable solution could not be found for getting the correct-sized gutters, we would get our deposit back. We have been trying to find a solution since the gutters were delivered. Tim and Zack had many text exchanges and phone conversations. On 8/18/25, Zack left Tim a voicemail saying he had been let go from the company. On 8/19/25, Carol Devia called me, and at that time, I informed her that this process had been so difficult and that we had lost faith that they could provide an acceptable solution for us. Carol told me to sign the Notice of Cancellation form and email it to her, which I did that same day. As of 8/28/25, we had not received a refund yet, so I called Carol back. She then informed me that Tammy, the owner, is the person who approves/provides any refunds, and she would, again, remind Tammy to call me. We have not received a refund, and the gutters remain in our side yard."

FAQs for flat, foam, or single ply roofing installation and replacement projects in Castro Valley, CA

Many roofing pros point to PVC as the top performer on flat roofs thanks to its tough seams and long-term waterproofing. A properly installed PVC membrane can last 30 years or more, resisting ponding water and harsh weather with ease. You will pay more up front than you would for EPDM, but the added durability often translates into fewer repairs and a lower cost per year of service.

Yes, a rubber roof is an environmentally friendly choice. Most rubber membranes contain recycled content and can reflect heat, which helps trim cooling bills in hot weather. Manufacturing has a lighter footprint than many traditional materials, and the long lifespan means fewer tear-offs headed to the landfill. If sustainability is a priority, ask your roofer about brands that carry third-party eco-certifications and confirm they meet local environmental standards.
