From a young age, Raul Diaz recognized his calling for quality installation. He began to see the necessity for devoted and passionate professionals to help homeowners and businesses realize their dreams. By 1989, he had embarked on a journey toward achieving perfection and client satisfaction. As his life progressed, the family legacy of excellence continued through his children. Ryan Diaz, one of Raul's sons, started working with him when he was just 12. Working with his father, Ryan gained valuable experience and insight from Raul's dedication and hard work.
“Some homeowners prefer to tackle parts of the project themselves, whether due to experience or a desire to save money,” they explain. “We stand out as the only company offering three unique plans to fit any project needs. We can manage the entire design and build process, or we can take care of specific aspects while leaving the rest to the homeowner.”
Raul and Ryan Diaz prioritize giving clients the freedom to select the level of construction services they require. Some homeowners opt to handle parts of the work themselves, either from experience or to save a considerable amount of money, they explain. We are the only company that offers three different plans to accommodate any type of project. We can oversee the entire design and construction process, or we can handle specific elements while allowing the homeowner to complete the rest.
Bay Valley Roofing highlights the significance of customer service in every part of our business. Building trust with our customers is our primary goal, and the most effective way to do that is by showing our dedication to quality service, says Raul Diaz. From providing daily project updates to offering completion timelines, we strive to keep them involved in the process as much as possible.

Recommended Customer Reviews
I'm so glad we chose Bay Valley Contractors for our rennovation project. They did some major work on our house, taking down a chimney (which involved re-roofing a section of our house and building some new walls) and repairing some structural issues. Raoul was very patient and always took the time to address our concerns thoroughly, and his crew did top-notch work! They were polite, friendly, and obviously skilled at what they do. My only complaint is that I wasn't thrilled with the windows subcontractor they brought in - there were some problems with the installation, and their crew wasn't as professional. But at the end of the day Raoul held them to a high standard and made sure they made it right. I was impressed with how he handled the issues. I would highly recommend them!
They used to have Bay Valley Roofing and Solar name on their biz cards. Hope they got rid of their roof repair estimator Gary Podaridis. That guy was a joke - showed up for a scheduled estimate without a ladder - twice. 1st time his excuse was, the co. doesn't allow him to go on a roof after rain, as it might still be wet. Fair enough. 2nd time, the roof was totally dry, he came in a small collectible car and, to avoid questions, started complaining about some damage to it even before we got a chance to say hi. Never sent any formal estimate, but tried to give some numbers based on a couple of my own photos of the problem areas.
Kelli R.Wanted to give a shout out to Bay Valley contractors. Had a fairly big addition which involves adding approximately 400 ft.² which consisted of a master bedroom and bath. Also converted one bedroom into a walk-in closet and hallway. All of the guys that worked on the project from day one to completion were professional, knowledgeable and tidy. Being a contractor myself I recognize that these guys were well organized and did good quality work. The job is complete and we are in our new master bedroom finally. Thanks to Raul and the crew!
Jeff O.Bay Valley came to my home and promised to make an estimate on repairs for an inferior roof installed by ""SOS Roofing"" &/or reroofing to solve this problem.
No estimate ever arrived after I called them several times asking for that promised estimate.
We went through hell after a roofer installed an inferior roof was installed and at least 20 roofing companies did the same. So, I wrote 2 articles about my experience to help others.
Ask me for links to:
[1] ""Before you consider hiring any contractor""
[2] ""GOOD NEWS: How to get a 50-100 year roof""
""Yelp"" won't allow me to share links to these articles which reveal how crooked Roofing companies can be & how Building Inspectors turn their backs on such activities.
Bay Valley Contractors came recommended by my solar installer, as I wanted to put down a new roof before getting solar panels. I replaced my rolled roof material with a 60mil white IB membrane (with 2 inch foam insulation and 1/4 inch DensDeck), and had new solar legs/brackets installed in coordination with the solar installer's crew.
Every interaction I had with the team at BVC was prompt and professional. It started with Edward, who was creative during the sales process, and ended with Raul who coordinated the project and kept me informed of any scope changes during construction. Nancy and Dean were also helpful over email and phone.
Changing your roof is an important investment. I have full trust in this team and wish them the best. Thanks for the great work!
Had my roof on my apartment building replaced. I'm very happy and highly recommend this company. Very professional and offer high end product at a reasonable price. Everything they did on a daily basis they would inform me with the progress. They also recommended me with a solar company that offers systems at a great price. I would go back to Bay Valley for any roof problems or replacements in the future.
C C.You get what you pay for. While they were not the cheapest bid we got, they were by far the most thorough, helpful, explained every detail, and walked us through every step of the process. Edward was so helpful before, during and after the project to make sure all our questions are answered. I was blown away by the quality and service and our new roof looks fantastic. Thanks Bay Valley
Kenny E.We were lucky to have Bay Valley Contractors replace our aging and damaged roof.
Raul and the team kept me informed each step of the way. They have a great reputation for a reason. The crew was respectful, hardworking, and paid attention to every detail.
The roof looks amazing and at their suggestion we added some extra insulation that has made a tremendous positive impact on our energy usage.
I recommend them to anyone that wants the job done right!
Stephen S.We had a huge home roofing job and Bay Valley Contractors did excellent work. Fair price. Talented and polite and friendly workers. Job done on time as promised. Raul the project consultant was great to work with. His team coordinated smoothly with our solar installer. The new roof makes our home look even better than ever. We can't really imagine a better experience.
Shar N.So impressed with this company. Not only were they quickly responsive but they were early for their appointment. Dean Mouser a project consultant fixed my leak in record time but was so nice and explained everything and did not even charge me. He said it was a birthday gift!! Now who can beat that??
When I need anything roof wise they are my guys!
I recommend to anyone needing work to try them you won't be disappointed.
