Your roof is the one thing standing between your possessions and the weather. So roof leaks, rain damage and seeping water can ruin your belongings and cause underlying problems, like water damage and mold if you need a new roof or ignore needed roof repairs.

It’s important to remember that the integrity of your roof depends on the quality of the Contra Costa County roofing company you hire. That’s why it’s important to find roofers who are experts in their field and have the necessary skill and experience when it comes to installing new roofs and repairing existing roofs, and they can offer a better overall value. Researching your options will help you find a high-quality roofing company in Contra Costa County, including those in the major cities of Concord, Richmond, Antioch, Pittsburg and Walnut Creek, as well as in the smaller towns and Pleasant Hill, San Ramon, Danville, Brentwood and Martinez.

Know What You Want from Your Contra Costa County Roofing Company
Before beginning your search, decide whether you simply need roof repairs or want to have your roof replaced. Once you’ve narrowed down the reroofing and roof repair services you need, don’t overlook the importance of aesthetics. Today there are many choices in roofing materials, including slate roofs, rubber roofing, asphalt shingles, metal roofing, concrete roof tiles and wood shingle and wood shake roofs.

It’s wise to match the project to a qualified roofer. Some local roofing companies in the larger Contra Costa County cities such as Concord, Richmond, Walnut Creek, Pittsburg and Antioch specialize in copper roofs and tin roofing, while others are able to install tile roofs, wood shake roofs and energy efficient roofing. If you need a new roof for your commercial building, remember that commercial and industrial roofing is a specialty. So be sure the roofing contractors you’re considering are able to meet the demands of installing commercial roofs.

You should also have an idea of when you want the project completed and specific expectations you have from the roofing work and the local roofers. By being prepared, you’re more likely to find a good roofing contractor for your job in Contra Costa County, including the cities of San Ramon, Danville, Brentwood, Martinez, Pleasant Hill and the smaller towns including West Pittsburg, Hilltop Mall, Maltby, Discovery Bay, El Sobrante and Pinole.

Why Do Research on Good Roofers in Contra Costa County in These Major Cities: Concord, Richmond, Antioch, Walnut Creek, Pittsburg, San Ramon, Danville, Brentwood, Martinez and Pleasant Hill
While it’s best to choose a Diamond Certified company that’s been rated Highest in Quality, that may not always be achievable. If you’re not able to choose a Diamond Certified roofing contractor in your area of Contra Costa County, improve your chances of hiring a good roofing company by looking up candidates on the Contractors State License Board website to ensure active license and workers’ compensation insurance. Violations will also appear on their license record, so you’ll know about recent infractions or serious customer grievances that have been processed by the state.

Then take time to verify roofing company qualifications. Some local roofing contractors in the major Contra Costa County cities of Walnut Creek, Brentwood, Pleasant Hill, Richmond, Concord and Pittsburg have even earned certifications from roofing manufacturers as endorsed roof system distributors and roofing installers who can shorten and ease the whole reroofing and roof repair process.

Some roof repairs can be quick projects, but large jobs like roof installations and reroofing may take days or even weeks. So it’s especially important to find a roofing company that has roofers who are dedicated to customer service and with whom you can work well. Professional qualities including promptness, friendliness and cleanliness are very important, especially because the roofers will be spending so much time working on your home.

Savvy consumers recognize that local roofing companies here in Contra Costa County are often their best option when hiring a roofer. That’s because roofing contractors who live and work in the local area may be most likely to offer quick emergency roofing repairs and reliable service for roofing installation and reroofing.

Further Research on Good Roofing Contractors In and Around Contra Costa County
Now you’re ready to talk with a few Contra Costa County roofers. If you live in one of the larger cities, including Concord, Martinez, Richmond, Walnut Creek, Antioch or Pittsburg, you will likely find many good roofing companies from which to choose. If you live outside these areas, keep in mind that many roofers are willing to travel to other parts of Contra Costa County, including the smaller towns of Pacheaco, Oakley, Rodeo, Vine Hill, Bay Point, Alamo, Lafayette, Cowell, Tara Hills and other areas including rural Contra Costa County.

Have a written list of questions when you interview roofing companies and write down the answers each company gives you. Remember, though, many roof contractors will not provide estimates over the phone without seeing the job first. However, don’t feel obligated to set an appointment for an estimate if you weren’t impressed with your initial contact with the roofers.

If the local roofing company representatives you’ve talked with don’t meet your expectations or can’t answer your questions satisfactorily, feel free to end the conversation and move on to the next high-quality roofers on your list, including those in the smaller Contra Costa County towns of Crockett, Kensington, Los Medanos, Port Costa, Rheem Valley and W Pittsburg.

It’s safer to choose a Diamond Certified roofer because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from a roofing contractor in Contra Costa County and the greater Bay Area, you can have confidence choosing a Diamond Certified company. Diamond Certified reports are available online for all certified companies.

And you’ll never be fooled by fake reviews. That’s because all research is performed in live telephone interviews of actual customers.

If you can’t find a Diamond Certified roofing company within reach, you’ll have to do some research on your own. If you do, it’s wise to call some references provided by your roofing company. Keep in mind, though, that references provided to you by the roofers are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process.

That’s because references given to customers from companies are cherry-picked instead of randomly selected from all their customers. If you do call references on your own, specifically ask for a list of the company’s 10 most recent customers. This will help avoid them giving you the names of only customers they know were satisfied.

The following are some questions to ask roofing company references:

  • Were you satisfied with the roof installation and the service from _(roofing company name)_?
  • What was the type and scope of roofing services they did for you?
  • Did the Contra Costa County roof contractor you hired finish the work on time?
  • Did the contractor keep you up-to-date on the status of the project?
  • Were there unexpected costs? If so, what were they for and were they avoidable?
  • If you live in a smaller town such as Walnut Heights, Blackhawk, Port Richmond, Briones, Canyon, Port Chicago or Clyde, did the roofers charge an extra fee to travel to your home?
  • Did the roofing company show up on time?
  • Did they clean up after finishing the roof installation?
  • If you need a new roof or roof repairs in the future, would you use this roofing contractor again?
  • Would you recommend them to friends or family?
  • Can I visit your home to see the completed roof installation or roof repairs?

Your choice of roofing contractor determines the value of your new roof and can impact the resale value of your home. So consider the following questions:

  • Can the roofing contractors meet your needs in terms of scheduling, products and installation preferences?
  • Do the Contra Costa County roofers have knowledge of the roofing products they sell and install?
  • Can the company contact tell you which roofing services and roof products best suit your needs and why (i.e. roof repairs, roof panel replacement, aluminum roofing, corrugated metal roofing, membrane roofing products, roof leak repair, ceramic tile roofing, cedar shake shingles, etc.)?
  • Is the roofing installation company sensitive to your budget? Most contractors will give you bids for good, better and best options that are flexible to fit your resources.
  • Do the roof contractors in Contra Costa County offer warranties in the event of a product failure or installation error? Will they put these guarantees in writing?

You may also want to examine your own expectations for your new roof, realizing that not all may be possible. For instance, it may not be reasonable to expect an uninterrupted schedule or a quiet worksite when getting a new roof.

So talk with your roofing contractor about what you can reasonably expect during the work. You are more likely to be satisfied if you go into the job with fair expectations.

The best roofing contractors in Contra Costa County, including those in the larger cities of Pittsburg, Martinez, Richmond, Concord, Antioch and Walnut Creek can be choosy about which roofing jobs they take. That’s because not every roofing company can handle every type of roofing repair or roof installation. So it’s vital to look for the high-quality roofing contractors that have the skill and knowledge to do the roofing work you’re looking for.

Once you’re narrowed down your choices by interviewing roofers, you may want to get several estimates, but limit it to a small number provided by the best roof contractor candidates. Roofers appreciate knowing that you’re looking for good service and fair prices rather than the lowest-cost roofing you can find. This will also improve your chances of finding a quality roofer who really understands their trade and provides the best quality workmanship on roofing installation and roof repairs.

Sign a Detailed Roofing Contract with Your Contra Costa County Roofer
When you’ve found the roofing contractor that meets all of your expectations, it’s the ideal time to ask for a written contract. The contract should include the cost of the job, details about the materials and installation information, such as projected start and end dates.

Read the entire contract and be sure you understand all the terms and limitations before you sign. Once you’ve signed a contract with a Contra Costa County roofing company, you have committed to abide by the information within the contract, so for your protection, never sign a blank or incomplete estimate.

Remember, the contract is there to protect you and your roofing contractor. So it’s advisable to write in any verbal agreements or special requests that you’ve confirmed with your Contra Costa County roofer. This includes any special agreements you’ve reached, such as reasonable expectations for the care of your home and yard during the roofing installation process.

It's the roofer’s job to install quality roofing products using the best possible installation techniques. But you play a big part in the success of your new roof installation, too.

Here are a few easy ideas that will help you be a good customer when hiring Contra Costa County roofing contractors.

  • Be clear and upfront with the roofers. Let them know what you want from your new roof, the outcome you’re expecting and specific ways they can meet your expectations.
  • Before you hire a roofing contractor, repeat your expectations and reiterate to the roofing company representative your understanding of the agreement. Most problems with local roofers occur because of a failure in communication. By being clear about your expectations and theirs, you can avoid most conflicts.
  • Ask your roofing contractor if you should call to check on the progress or if the company will call you with regular updates.
  • Give the roofing company service representative a phone number where they can reach you at all times while reroofing your home or completing your roofing repairs. The work will move along more smoothly and your roofer will be able to call you for necessary updates, questions or work authorizations.
  • When your contractor contacts you, return calls promptly.
  • Pay for the roofing work as promised in your contract.

Why would you want to be a good customer? Roofing contractors in Contra Costa County appreciate customers who are straightforward, honest and easy to work with. Your good customer behavior sets the tone from your end and creates an environment conducive to a good relationship. Things may very well go smoother and any problems may be more easily resolved.

Simplify the Job for Roofing Companies in Contra Costa County
Before the work has begun and while it’s in progress, keep in mind ways you can make the job easier for your roofing contractors. While the Contra Costa County roofing contractors you’ve hired should be professionals who are able to deal with difficulties and unexpected situations during roof construction, you can take small steps to simplify the work. Not only will this create an atmosphere of cooperation and goodwill, but it can also save you money by preventing unnecessary delays and extra work.

Clear the area. Before the job starts, survey your property for potential hazards and items that may make the job harder or add time to the job. This includes low hanging branches near the roofline, trees or shrubs that make it hard for the work trucks to enter your property or pull up to the work site, or lawn furniture or decorations that may be in the way. You may even want to plan a pre-work walk-through with the roofing company foreman to locate challenges they may see.

Keep children and pets away from the worksite. It is unsafe for your loved ones to be near the construction, and it also can also add time and expense to the job if the roofers have to watch out for pets or children. If your pets use the yard near the roof construction area, take them out on leash during the roof installation work in case the roofers forget to close gates or need to leave open yard access.

Ask what you can do. Your Contra Costa County roofing professional should be able to tell you if there are any items you can take care of in order to simplify the job. In some cases, it may be easier and less expensive for you to handle tree trimming, roof cleaning or moving vehicles before the construction crews arrive.

Stay in touch. Make sure your Contra Costa roofing company has contact information so they can reach you at all times, such as a cell phone or work phone number. This can limit costly delays if they need to reach you with updates, questions and authorizations for unforeseen situations.

Roof Shingle Installation
Roof shingles, including those made by Owens Corning, CertainTeed, IKO, Tamco, Celotex and GAF-ELK roofing, are a roofing choice made of individual, overlapping roof shingles. Most are laid in rows with the top shingles overlapping the lower shingles. Roofing shingles are typically made of asphalt, but can be metal shingles, stone shingles, tile shingles or wood shingles. Roof shingles come in a variety of colors and styles.

Flat Roofing Repair & Installation
Flat roofs are horizontal or nearly horizontal to the building. They may be residential or commercial roofs, and are often made of tar and gravel, rubber roofing, membrane roofing or metal roofing. Many buildings incorporate flat roofing so that they can support HVAC systems, living roofs/green roofs and living areas on the roof surface.

Roofing Tile Installation
Clay tiles, solar roof tiles, slate roof tiles, concrete roof tiles, plastic tiles, cedar tiles and ceramic tiles are all popular roofing tile choices in Contra Costa County. They are long-wearing, unique and often sustainable roofing options. Roofing tiles are available in many styles, including flat tiles, imbrex and tegula tiles, Roman tiles, mission or barrel tiles, interlocking roof tiles, and interlocking pantiles.

New Roof Installation
New roof installations on new homes and existing structures are a complete replacement of existing roof structures. New roofs are recommended for existing homes that have leaky roofs that regular roof repairs won’t fix. New roofs are installed by roofing contractors and may include tile roofs, rubber roofs, shingle roofs, wood shingle roofs and metal roofs.

Roof Replacement
Roof replacement is the total removal and reroofing of an existing building. Roof replacement is an alternative to roof recovering, and is often called re-roofing or reroofing. Reroofing can change the shape or style of an existing roof, and may incorporate new roofing systems or roofing materials to update and add value to a home or building.

Rubber Roof Repair & Installation
Rubber roofing, often installed in rolled roofing form or liquid rubber roofing, is a specialized roofing cover for roof repairs or new roofing. Rubber roofs may be a good choice for roofs that leak or for flat roofs. Rubber roofs are often installed on commercial and industrial buildings, but are available as rubber roof shingles and recycled rubber roof tiles for residential homes.

Roof Panel Installation
Roof panels are often made of corrugated metal or translucent fiberglass, and they are good choice for homes, greenhouses and patio covers. Metal roof paneling comes in a variety of colors and styles. Roof panel installation is often quick and attractive, and the lightweight panels are a good choice for commercial or residential roofing.

Metal Roofing Installation
Metal roofing is a popular choice for its durability, flexibility and number of colors and styles. Once known as tin roofs, metal roofing is available as copper roofing, aluminum roofing, steel roofing, stainless steel roofing, corrugated roofing, standing seam metal roofing, metal shingle roofs and metal panel roofs. Metal roofing is weather resistant, lightweight and portable and is often used on residential buildings, commercial buildings and industrial buildings.

Steel Roof Installation
Steel roofs and stainless steel roofing is a good choice for harsh climates and as a design element for modern homes. Most steel roofs are installed as rolled roofing, standing seam roofs or metal shingles. Some steel shingles mimic the appearance of slate shingles, wood shingles and tile shingles with the strength and durability of steel roofing.

Roof Repair

Other common roof repairs in Contra Costa County including in the larger cities of Brentwood, Concord, Richmond, Walnut Creek, Antioch, Pittsburg are required to fix improperly installed gutters, roof leaks, missing shingles, roof flashing leaks, skylight flashing, roof valley flashing, roof ridge vent damage, gutter problems and nail holes.

Frequently Asked Questions
Roofing Contractor FAQ

Q: Why choose a Diamond Certified Roofing Contractor?...

Q: Why choose a Diamond Certified Roofing Contractor?
A: Diamond Certified helps you choose a roofer with confidence by offering a list of top-rated local companies who have passed the country’s most in-depth rating process. Only local roofing companies rated Highest in Quality earn the prestigious Diamond Certified award. Most local roofers can’t pass the ratings. American Ratings Corporation also monitors every Diamond Certified company with in-depth and ongoing research and ratings. And your purchase is backed by the Diamond Certified Performance Guarantee. So you’ll feel confident choosing a Diamond Certified roofing company.

Q: Do I know if I need a new roof or roof repairs?
A: Good roofing contractors will inspect your roof and help you decide whether roofing repairs or a new roof is the best solution. Smaller areas of damage and minor leaks may be fixed with simple roof repairs. Extensive missing or damaged shingles, rotting roof boards, high energy bills, water stains on interior ceilings and walls or large roof leaks may indicate that a roof replacement is needed.

Q: What roofing materials can I choose from?
A: There are several types of roofing materials that are popular among local homeowners:

Asphalt shingles are a common choice for new roofs. They are reasonably priced, range from simple three-tab shingles to durable architectural shingles, come in many colors and types and are easy to repair. Asphalt shingles have a shorter lifespan (about 15 to 30 years) and aren’t as environmentally-friendly as some other roofing material choices.

Wood shingles and wood shake roofing are usually made from cedar wood. They often blend in with a natural environment, weather to an attractive grey color and are easy to repair and replace. Wood shingle roofing can last 30 to 50 years if it’s maintained properly. However, wood shingle and shake roofing can be expensive ton install and requires more maintenance than other types of roofing.

Tile roofing is a popular choice for new roofs because it is durable and attractive. Roof tiles can be made from concrete or clay and come in several colors and styles. Tile roofing is easy to maintain, fireproof and very durable. Tile roofing can be expensive, heavy and is generally a better choice for new homes because of the structural requirements due to the weight of the material. Tile roofing can also be fragile and repairs can be complicated.

Metal roofing, including copper roofs, steel roofing, aluminum roofing and tin roofs, is becoming a more common choice. While it can be expensive to install, metal roofing is very durable and will outlast other roofing materials. It is lightweight, comes in many colors and has a long lifespan—at least 50 years in most cases.

Slate roofing is a beautiful and unique choice. It is fireproof, low maintenance and lasts years longer than other roofing materials. However, slate roofing can be expensive, require specialized installation, and require more maintenance than other types of roofing.

Q: How do I know which type of roof is the best choice for my home?
A: Each home is different, just like the needs of the homeowners. Your roofing company can help you choose the best roofing material and roof style for your home, your budget and your unique wishes.

Q: How long will it take to re-roof my house?
A: Roof replacement can take a few days to several weeks depending on the size of the home and the roofing materials used. Weather and the skill and experience of the roofing contractors can also have an impact on the speed of the re-roofing process.

Q: Should I choose tear-off re-roofing or a roof-over roof construction?
A: Some roofing contractors will install a new roof on top of your existing roof, known as a roof-over or roof overlay. This can save some money on the roofing project since there are no costs for roof removal. However, other roofing companies recommend removing the old roof before installing the new roofing material, known as tear-off reroofing, for a better quality roofing job. Talk with your local roofer in detail about your specific reroofing needs.

Q: Are there eco-friendly roofing materials and methods I can choose from?
A: Yes. A new roof with good insulation can make your home more energy efficient and keep it more comfortable. There are also several ways to make your roof installation more eco-friendly. First, find out if your roofing contractor can recycle old roofing materials. Some roofing contractors dispose of old roofing shingles and materials in a more environmentally-sensitive way. It’s also possible to choose eco-friendly roofing materials for your new roof. From green roofs (roofs that are partially or completely covered with vegetation) and environmentally-friendly composite shake roof shingles to recycled shingles and metal roofing, there are many environmentally-friendly roofing options your roofer can offer.

Q: What happens if someone gets hurt while working on my roof?
A: When you hire legitimate roofing contractors with the correct license, liability coverage and workers’ compensation insurance, you won’t have to worry. Workers’ compensation insurance covers every employee of the company in the case of accident or injury. You will not be held responsible for damages. Make sure you ask your roofing contractor to show you a copy of their active workers’ compensation policy. All Diamond Certified roofers have had to prove they are licenses and carry worker’s compensation insurance in order to pass the Diamond Certified ratings process.
