Constraction reviews in Hayward, California

Update 7/9/22. We just had Century Roof and Solar install two Generac generators (at two separate houses) and the installation went off without a hitch. They clearly explained the process, were on time, the staff is very courteous, and the workmanship is excellent. Like the roof and solar installations they did for us, I would not hesitate to use them.

We used Century Roof and solar for 3 roof replacements and 2 solar installations. They did a great job. Tony communicates exactly what is going to happen, they are on time, they clean up very well after each day. would use them again in a heartbeat.

Century Roof and Solar provided excellent services for our home roof. They installed our new roof at a very timely manner and at a very best price. Their responses are great. Tony, Elena, the office staffs, and whole crew are the best people. Century Roof and Solar team are very helpful, friendly, and dedicated to our needs. We recommended their services to our neighbors and they hired Century Roof and Solar as well. We definitely recommend Century Roof and Solar to everyone who needs a new roof or any repairs for their roofs. Tony and Elena are the best and a very responsible team to count on!

We had a very good experience with century roof and solar. They did the uninstallation and reinstallation of our solar panels as well as roof replacement, gutter replacement, and installation of gutter guards. Communication was always very prompt and easy. We also paid to have our solar panels cleaned once they were put back on the roof. The workers were very respectful and did not leave a mess behind. The work seems very high-quality and looks great. Thank you!

We had our fair share of not so great experiences with contractors since buying our house and our project with Century was a rather large financial commitment (roof and solar and batteries), so we were nervous... really nervous.

Tony came personally to our house to inform us about our options and also to introduce himself, his company and his work ethics and we had instantly a very good impression. All communication was thoroughly and in a timely fashion. His bid was self explanatory and easy to understand and even if there were misunderstandings they were solved in a very professional matter.

We've got some delays due to the lengthy permit process including some rather exhausting requirements from the City, that Tony and Century completely handled for us.

The whole installation was as non invasive to our daily life as humanly possible. The demolition was done quickly (pretty much one day of really loud work) and every crew (demolition, installation, electric) was always on time, always happy to answer questions and explain everything.

We did have some dry rot. This was already mentioned by Tony the first day we met, after he climbed up our roof to have a first look. The main chunk of the dry rot repair costs were covered by his initial bid and any additional costs were explained by the crew and explained in written form via email plus photos.

Century also handled the interconnection with the utility for us - which was again a rather lengthy and time intensive process.

The installation was flawless and handled with great care and knowledge. So no surprise that we highly recommend Century after this lengthy review;-)

We desperately needed one replacement tile that was out of circulation. Visited and contacted many different companies but couldn't find it. Two companies recommended Century Roof and Solar. Left a message which was promptly responded with a callback from Nika who was so helpful. She again texted me in the morning that the item was found! Within 24 hours the stressful problem was resolved. Went to pick it up from Elena, the owner who was very nice snd kind. Thank you, Century Roof!!! Hope to do business with you again!!!

We got our new roof and solar panels in December 2019. The process was smooth, easy, and completely stress free. The solar panel company has filed bankruptcy. Instead of waiting for us to call and ask what to do, Tony Diaz reached out to us before we even thought of it with information on the status of the bankruptcy, what it means to us, how to register our warranty with the new company, etc. Way above and beyond in dealing with us, customers who bought a roof and solar for him five years ago. I can never say enough good stuff about these guys, they're the best.

Tony Diaz and his company, Century Solar installed our solar panels - - twice!! Manufacturer defects in our panels resulted in the second installation. Tony was integral in dealing with the manufacturer. Our claim was reduced to a class action litigation where we joined multiple plaintiffs, as a class, against multiple manufacturers (including our manufacturer) and distributors, as the defendant class. Tony was instrumental in helping plaintiff’s lawyers understand the solar industry and developing the litigation theory, strategy and tactics. The litigation was settled in favor of the plaintiffs. We received new panels – which Century installed. That was almost 10 years ago and here we are again faced with additional issues on the second install. Once again, Tony stepped up. There are plenty of horror stories in the solar panel industry. We came close to having our ‘horror story’ with our manufacturer – but not our installer thanks to Tony Diaz. We unqualifiedly recommend Tony and his company, Century Roof & Solar.

Century Roof and Solar replaced our old roof in 2022 and installed solar panels in 2023. The quality of the work was exceptional. Although quote came in on the higher end, the craftsmanship was well worth the cost. Both the roof and solar panels were done as planned and on time, and they cleaned the site at the end of every day. His team was outstanding, skillful and friendly which exceeded my expectations. They took their time carefully handling all installations efficiently. I felt very comfortable selecting Century Roof and Solar as Tony’s team has been in the business for a long time and came in highly recommended by others.

We could not have asked for a better experience with Century Roof and Solar. The service level from start to finish was perfect. The various crews worked diligently all day with a great clean up at the end of each day. Our Presidential TL Solaris roof looks wonderful and we couldn't be more pleased.

I was referred to Century Roof and Solar by a trusted contractor friend, and I’m very glad I took his recommendation. We had seven new replacement skylights installed and also needed some previous roof damage repaired. From start to finish, the experience was excellent.

The entire Century team (including the office staff) was both highly skilled and genuinely personable. Every employee we interacted with demonstrated professionalism and clearly knew their craft, which gave us a lot of confidence throughout the project.

The finished work exceeded our expectations. The skylights look fantastic, the roof repairs were done seamlessly, and everything was completed with great attention to detail. We couldn’t be happier with the results and would absolutely recommend Century Roof and Solar to anyone looking for quality roofing or skylight work.

We needed some roof tiles to replace the broken ones when we replaced some of the damaged wood trim. I called Century Roof and Solar and was greeted by Kyla. She was very nice and efficient: asking the right questions and giving out precise information.
When I came to pick up the tiles, even though it was 'wrong' hours (not between 6:30 and 8:00 am) Elena (?) was very helpful and got the tiles I needed.
It was a small transaction. But I believe that if one does well in small things, one will do well in big things.
I will definitely come back to Century Roof and Solar if I have any need, big or small, in the future.

We were considering roof solar panel for our house. Tony did the analysis and determined it does not meet our needs. He recommended a back-up generator and sound proofing box. He is very knowledgeable and provided good guidance. He shared his sources for equipments and his pricing was competitive.

They did the permitting and Installation. Job site was clean, showed up as promised and complete the job as planned.

We highly recommend Century Roof and Solar. Tony will provide the best service in our area.

Tony and his two-man crew were outstanding. It took 5 working days to install 20 Sunpower panels, run the wiring, install panel boxes, remove 2 whirlybirds, and replace them with a roof ridge line vent. Tony arranged for the inspector to come out the day after the work was done! That morning Tony arrived a couple hours early to make sure everything was looking good for the inspection and that the panels were generating power for the house. It not only passed, the inspector took pictures to use as examples for other installers. Tony then spent an hour answering my list of questions regarding next steps. Thankfully he was submitting the "passed inspection" information to PG&E and the technical info that goes along with it. The next day I was cc'd on his email to PG&E. Five days later, I received an email confirmation from PG&E that the info Tony sent was processed and PG&E was recording credits for my system. Everything was completed in less than two weeks. Impressive from beginning to end.

I really enjoyed my experience with Century Roof and Solar. Their team was professional, prompt and knowledgeable. The workmanship was outstanding.

Tony came out to do the initial site visit and go over all the options. He explained things enough for me to make an informed decision. He didn’t hard sell any upgrades that didn’t make sense.

After his visit I received a proposal with all the different options, and costs for each, clearly outlined. This saved some confusion when the office staffed noticed an omission a few days after we agreed on a scope of work and a price. Because their proposal outlined all the options I could clearly see the clerical error that resulted in the mistake. We adjusted the proposal and moved forward. They were clear about their schedule and let me know when they would be available to start.

They were very accommodating when I needed to change the schedule to due to a conflict with another project. When the start date finally arrived the crew showed up ready to work.

They were very considerate of our extensive garden and I’m really glad they had all those young backs to haul all the debris up the three flights of stairs and the new material down those same stairs.

I hopped up on the roof myself once or twice a day. Both to check on workmanship and to discuss issues that Pedro, the foreman, discovered. Dry rot, missing trim, and missing sheathing. All additional work was clearly explained, fairly priced, and nicely executed.

The end result is a roof I feel very confident will last another 30-40 years.

As a construction contractor myself I really appreciate the whole experience dealing with the Century Roof team. I would definitely feel comfortable bringing them on to another project.

I contracted Century Roof and Solar to repair my roof. Tony (owner) visited my home for a consultation and was very thorough in explaining my options. It was a clear he was a man who knew his roofs. His back office team was always respectful and responsive. The roofing crew was always on time and did good work from what I could see. There was one moment where a vent was accidentally damaged (I had an bad roof so not all their fault) during the initial consultation and Tony had a crew member come fix it for free, so clearly a man of integrity and customer first mentality. Tony also took a video call with me to talk through the statement of work and contract with me. His team pulled permits and did things right and by the book. I do wish the crew themselves were a bit more communicative of what was going to happen but maybe I'm just too much of a neck breather when it comes to knowing what's happening. They painted parts of my house and lining that were damaged due to work and damage from a different contractor. These weren't even a part of the original SoW with Tony so another customer first example. Anytime there was an issue or something wasn't 100% right, Tony got a guy to come out and make it right. If there was an additional cost, they were upfront about the cost before I ever signed so I knew what I was walking into if there was more to be done than planned. Crew members would always take picture and show me why something needed to be fixed. I do advise that clean up isn't perfect and they do their best but also double check after they leave. It's been about a year since they fixed the roof and it survive the rainy seasons. The house is clearly retaining heat better than before. Overall nice crew, great owner, and a roof that does the job right.

It’s good to know that there are still honest and hard working people that truly want to help their customers. The process of replacing my tile roof, gutters and insulation with Century Roof and Solar was an easy and painless experience. The materials and workmanship are of the best quality. It was a joy to have worked with them.

Co-worker suggested Century Roof and Solar, went with the factory install. So I could transfer material and labor, to the new owner when I sell. Tony (owner) Pedro, Mark, Jose and to all the other workers, set the standard in roofing industry. From the field workers and office workers take pride in there jobs.

Century Roof and Solar replaced our very old tile roof with composition shingles. To say the roof is beautiful would be an understatement. It is gorgeous!! And what a treat to work with the wonderful staff who were so particular each day with clean-up and so friendly.

The flooring guys that came to my apartment refused to take of their shoes when I asked them to, and then didn’t clean up after themselves before they left —including the footprint one of them left on the wall.

Outstanding company to work with. Prompt communication, very well skilled and they take pride in their final product.

Honest owner. Fast and reliable.
