I would say I had a great experience working with them.

They showed up at the time they promised, and they knew how to do the job properly. It's nice to know that they stand behind the work that they do.

They're very professional and thorough. I think they're an excellent company to do business with.

Everyone I dealt with was just fantastic. I'm happy they fixed my roof. It was leaking pretty bad, and nothing I did seemed to work.

Comparative Summary

Maintaining customer satisfaction is a crucial aspect of any business, but it’s even more important for general building and roofing contractors that have earned the prestigious Diamond Certified award. For Bay Valley Contractors, the key to achieving and maintaining high levels of customer satisfaction is consistently implementing a variety of creative and inventive elements to make each client’s project as unique as possible. “We enjoy working closely with our customers, visualizing their ideas and turning those visions into reality,” says co-owner Raul Diaz. “It’s very gratifying to see their happy faces at the end of their projects.”

Bay Valley Contractors has been installing roofs and solar power systems, building home additions, and remodeling kitchens and bathrooms for homeowners in Solano, Contra Costa and Alameda Counties since 1989. As a certified installer of GAF roofing products, the family-owned and operated company is qualified to work on a wide variety of roof types, including metal, slate and three-tab shingle.

Unlike less experienced contractors that take a hands-off approach to customer service, Bay Valley Contractors strives to build lasting relationships with its clients that are based on mutual respect and effective communication. “There’s no good relationship without good communication,” says Mr. Diaz. “By keeping open lines of communication between our employees and customers, we’re able to work through any potential issues and ensure positive experiences for everyone involved.”

Another feature that sets Bay Valley Contractors apart from its competition is its unique, three-tiered pricing system, which enables each customer to choose a building plan that provides the precise level of comprehensiveness they require. “We offer three basic packages: the 101, the 201 and the 301,” explains Mr. Diaz. “The 301 entails the whole project from start to finish, while the lower-numbered plans are for homeowners who want to reduce costs by doing some of the work themselves. The purpose of these systems is to provide our clients with numerous options: whether they want us to complete the entire project or just do the basic structural work, we can accommodate.”

Industry Info

Consider the benefits of a metal roof. The most common roofing materials in the United States continue to be composite, tile, wood shake, shingle and concrete, but more and more homeowners are discovering the versatility and strength of metal roofing. If you’re undertaking a roofing project, consider the following information to determine if metal roofing is a good choice for your home:
Durable. Metal roofs stand up to heat, cold, rain, wind, hail, rust and damage. If they become damaged, they’re relatively easy to repair.
Lightweight. Composition roofing weighs about three to four pounds per square foot, and cement tile can weigh up to 10 pounds per square foot. On the other hand, a high-quality steel roof weighs only one-and-a-half pounds per square foot.
Quiet. Modern steel roofs aren’t the same as tin roofs. Built with an added air space between the roof deck and the new roof, metal roofs actually dull most sounds.
Insulating. Metal roofs have air pockets that allow air to flow under the metal panels, which decreases temperature and insulates homes. They also cool down faster than composite or concrete roofs, so less heat seeps into homes. Some steel roofing contractors will even install systems over existing roofs, such as wood shake roofing.
Long-lasting. Most steel roofs last for 80 to 100 years, while composition roofs only have a lifespan of 15 to 20 years.
Variety of styles and colors. The newest generations of steel roofing can be aesthetically pleasing on any style of home. New styles and colors are always being introduced into the market, and your contractor can help you find the best match.
Green. Many manufacturers are using 30 to 50 percent recycled steel in their metal roofing products. Traditional composite roofs can’t be recycled, and neither can most wood shake roofing.
Guarantees. Most other types of roofs come with limited warranties, but many metal roofing companies offer extended warranties of 50 years or more. Some are even covered by transferrable lifetime warranties.

Frequently Asked Questions

Q: Do you offer competitive rates?

A: Yes, but we’re rarely the lowest bidder because we refuse to compromise on quality. We give fair prices for the work we do, and that’s what matters most to our customers.

Q: How soon can you start my project?

A: It depends on the type of work. When it comes to roofing, we can typically start in about one week. For a building project, it’s a matter of scheduling a time to bring in the draftsperson and start the design process. Once they do the measurements, we can usually have a floor plan ready within two weeks. After you sign off on the plans, we can move on to the next phase.

Q: How long will it take to complete my project?

A: Most jobs take four to five weeks to complete, allowing for inspections and possible delays. But we always finish ahead of schedule. For instance, we can remodel a three-wall, 400-square-foot family room in three weeks, and that type of work entails framing, roofing, siding and windows.

Q: How do your 101, 201 and 301 systems work?

A: These numbers represent different levels of plan comprehensiveness. The 101 package includes the plans, permits, foundation framework, roof gutters, siding, windows, rough electrical and any mechanical work, but it leaves some of the non-structural work (insulation, sheet rock, wood trim, doors, interior finishes, painting and floor coverings) for the homeowner to complete under our direction. This package enables capable homeowners to get some hands-on involvement with their projects and save a substantial amount of money.

With the 201 package, we do a little more of the work, including the sheet rock and insulation. Typically, we’ll leave the painting, floor covering and trim work to the homeowner—it’s lighter work, but it still lets them be involved and save some money. For those who want us to handle the job from start to finish, we offer the 301 package. The homeowner picks out the colors and finishes and approves the plans; we do the rest.

DIAMOND CERTIFIED EXPERT CONTRIBUTOR ADVICE & TIPS FROM Ryan Diaz

Expert CONTRIBUTOR PROFILE
  • Ryan Diaz is a second-generation roofing professional and vice president of Bay Valley Contractors, Inc., a Diamond Certified company since 2012. He can be reached at (925) 726-3792.

Ryan Diaz: Generational Synergy

By James Florence, Diamond Certified Resource Reporter

CONCORD — Despite being a roofer’s son, Ryan Diaz had little interest in nailing shingles or handling hot tar. However, when he applied his administrative proficiency alongside his father’s hands-on experience, it resulted in a potent combination. “My dad founded Bay Valley Contractors in 1989, and I started working with him on jobsites when I was about 12 years old,” he remembers. “However, my strengths were always more on the administrative and management side than in working with my hands. Eventually, I found my abilities could be applied to helping my dad run his business, and we’re still working together today.”

Today, as vice president of Bay Valley Contractors, Inc., Ryan says his favorite part of his job is the encouragement he receives from positive customer feedback. “I love hearing from happy customers. Just the other day, I called a customer to ask about his experience and he said he couldn’t have asked for a better contractor. That’s the kind of feedback that really makes my day.”

A resident of Vallejo, Ryan expresses his appreciation for the character of Bay Area life. “The Bay Area is such a beautiful, diverse place,” he affirms. “I have conference calls with people all over the United States, and I’m often reminded of how lucky I am to live here. It’s easy to take it for granted, but if you take a second to look, you realize how special it is.”

Outside of work, Ryan likes to stay active with activities like swimming and going on walks with his boxer, Max. He also maintains a keen interest in gardening. “My dad built me a huge garden bed, and every spring I’m in there tending to my vegetables.”

In regard to a professional philosophy, Ryan espouses the importance of customer satisfaction. “Our customers are the core of our business, so at the end of the day, our job is to keep them happy,” he explains. “Sometimes that means losing some money on a job, but even then, that customer will probably tell their friends how we helped them. In that case, even if we lose money, we win some good word of mouth, which leads to more work in the future.”

When asked the first thing he’d do if he were to retire tomorrow, Ryan says he’d look for a new livelihood. “I really don’t see myself retiring, as in moving to Florida and spending my days sitting in a lawn chair. If I did leave the roofing business, I’d probably just get involved in something else. Maybe I’d start flipping houses or become a property manager. Just something to keep my mind active—after all, if you don’t use it, you lose it.”

Ask Me Anything!

Q: What’s your favorite local restaurant?
A: I Love Teriyaki & Sushi in Concord.

Q: If you could travel anywhere in the world, where would you go?
A: London. I’ve always been fascinated by British culture.

Q: What was your favorite Halloween costume as a child?
A: A Power Ranger. That was the big show when I was growing up.

Q: Music or talk radio?
A: Music.

Q: What’s your favorite thing to eat for dessert?
A: Chocolate lava cake a la mode.

  • Innovations in Roofing Technology

    NOVATO — Thirty years ago, the average roof basically had a two-fold composition: shingles placed over a felt underlayment. In the decades since, roofing manufacturers have invested much into research and development, with the aim of improving roof performance and longevity. Today, these ongoing innovative efforts have culminated in what’s called the “roofing system.”

    The term “roofing system” refers collectively to the various elements that make up a modern roof, from shingles and underlayment to leak barriers and ventilation. By working together, these elements form a “system” that helps ensure long-term durability. Since roofing systems substantially increase roof lifespan, manufacturers are able to offer extended warranties on roofs built in accordance with their system-based specifications. So, if you’re in need of a new roof, ask your contractor about the benefits of a roofing system.

    Complete Video Transcription:

    NOVATO — Host, Sarah Rutan: Roofing technology has come a long way in the last 30 years, which is why today’s manufacturers are able to offer better warranties than ever before. Today we’re in Concord with Diamond Certified Expert Contributor Ryan Diaz of Bay Valley Contractors to learn more.

    Diamond Certified Expert Contributor, Ryan Diaz: So, 30 years ago roofs were comprised really of just, you know, a 30-pound felt underlayment and a shingle. And that was what made the roof. And today these manufacturers have really dove into research and development for these to create whole systems that will really get the lifespan of 50 years out of these shingles. They really work on the leak barrier, roof deck protection, what kind of shingle, proper ventilation. All these things kind of form into a roofing system. And that’s really what a lot of manufacturers are able to offer, these good warranties on their products now.
