Everything in your home depends on the integrity of your roof. If your roof leaks or needs roofing repairs, rain damage and seeping water can ruin your belongings and cause underlying problems, like water damage and mold.

But the integrity of your roof depends on the quality of the Sonoma County roofing company you choose. That's why it's important to hire roofers who are true professionals. Expert roofing contractors 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 Sonoma County, including those in the major cities of Santa Rosa, Petaluma, Rohnert Park, Healdsburg and Windsor, as well as in the smaller towns and West County to complete your project.

Know What You Want from Your Sonoma County Roofing Company
Before you start your search, know whether you need roof repairs or want to have your existing 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 Sonoma County cities such as Santa Rosa, Petaluma, Windsor, Healdsburg and Rohnert Park specialize in copper roofs and tin roofing, while others are able to install tile roofing and energy efficient roofing. Likewise, commercial and industrial roofing is a specialty. If you need a new roof for your commercial building, be sure the roofing contractor you're considering is skilled at installing commercial roofs.

You should also be ready to discuss a timeline for the project and any expectations you have for the roofing work and the service you receive from the roofers. By being prepared, you're more likely to find the best roofing contractor for your job in Sonoma County, including the cities of Sonoma, Cloverdale, Sebastopol, Cotati, Guerneville and the smaller towns.

The Value of Researching Good Roofers in Sonoma County
While it's best to choose a Diamond Certified company because they're rated Highest in Quality, that may not always be possible. If you're unable to choose a Diamond Certified roofing contractor in your area of Sonoma County, you can improve your chances of hiring a good roofing company by checking out 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 credentials. Some local roofing contractors in the major Sonoma County cities of Windsor, Sebastopol, Guerneville, Petaluma, Santa Rosa and Healdsburg have even earned certifications from roofing manufacturers as authorized roof system distributors and roofing installers who can simplify the entire reroofing and roof repair process for you.
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 Sonoma 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 These Major Sonoma County Cities: Santa Rosa, Petaluma, Rohnert Park, Windsor, Healdsburg, Sonoma, Cloverdale, Sebastopol, Cotati and Guerneville
Now that you've done some initial research, talk with a few Sonoma County roofers. If you live in one of the larger cities, including Santa Rosa, Cotati, Petaluma, Windsor, Rohnert Park or Healdsburg, you will find many good roofing companies to choose from. If you live outside these areas, keep in mind that many roofers are willing to travel to other parts of Sonoma County, including the smaller towns of Graton, Occidental, Bodega Bay, Monte Rio, Camp Meeker and other areas including West County.

When you interview the roofing companies, have a written list of questions and write down the answers. 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 Sonoma County towns of Glen Ellen, Forestville, Cotati, Penngrove, Russian River and Salmon Creek.

Questions to ask Local Roofers on the Phone

  • Has your local roofing company earned and maintained a Diamond Certified rating?
  • Are you a licensed roofing contractor?
  • What is your state contractor license number?
  • Do you have active liability and workers' compensation insurance? Are all of the workers you employ covered by this insurance?
  • What is your specific experience with new roofing installations and roof repairs in Sonoma County?
  • I live in _____ (Santa Rosa, Petaluma, Rohnert Park, Windsor, Sonoma, Sebastopol, West County, etc.). Do you charge for roofing estimates?
  • Will my project require a permit? If so, will you get the permits for me? (Beware of contractors who ask you to take out permits. This may be a sign they're not licensed contractors.)
  • Do you have your own roof installation crew, or do you subcontract roof installations here in Sonoma County?
  • Are you personally on site during the roofing process? If not, who is in charge of the roofing crews?
  • Is there a specific roof brand and type you recommend (GAF-ELK Roofing, CertainTeed Roofing, Owens Corning, Monier LifeTile Roofing, IB Roof Systems, etc)? Why?
  • How long has the manufacturer been making the roof shingles or roofing systems you install? (A lifetime warranty is worthless if the manufacturer goes out of business.)
  • Are you authorized by the manufacturer to install new roofs (such as an Atlas Roofing Certified Installer, Certified Duro-Last Roofing Installer or Certified Georgia-Pacific Roofing Installer)? Remember: Installation by unapproved roof contractors could void your manufacturer's warranty.
  • What guarantees and warranties do you offer on your new roofs and roof repairs? (In addition to the warranty on the roofing materials.)
  • How long have you been a roofing contractor in Sonoma County?

It's best to choose a Diamond Certified roofing contractor because all certified companies have passed an in-depth ratings process that most other companies can't pass.

If you want quality from a roofer in Sonoma 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. So the contractors will likely give you a few customers to call that they know are satisfied.

If you do call references on your own, specifically ask for a list of the roofing 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 Sonoma County roofing company references:

  • Were you satisfied with the roof installation and the customer service from _(roofing company name)_?
  • What was the type and scope of job they did for you (reroofing/roof replacement, roof repair, roof weatherproofing, roof leak repairs, etc.)?
  • Did the Sonoma County roof contractor you hired complete 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 Penngrove, Lytton, Salmon Creek, Fulton, Roseville, Fort Bragg or in West County, did the roofers charge extra to travel to your home?
  • Did the roofing company employees show up on time?
  • Did the employees clean up after finishing the 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?

In Sonoma County, Including the Major Cities of Santa Rosa, Healdsburg, Petaluma, Rohnert Park, Cotati, Windsor, Cloverdale, Sonoma, Sebastopol and Guerneville
Your choice of roofing contractor determines the value of your new roof and can impact the resale value of your home. So before deciding on the best roofers in Sonoma County for your roofing job, it's important to consider the following questions:

  • Can the roofing contractors meet your needs in terms of scheduling, products and installation preferences?
  • Are the Sonoma County roofers knowledgeable on the products they sell and install?
  • Can the roofing company liaison tell you which roofing services and roof products best suit your needs and why (i.e. roof leak repairs, roof panel replacement, aluminum roofing, corrugated roofing, membrane roofing products, ceramic tile roofing, wood roof shingles, etc.)?
  • Is the roofing installation company sensitive to your budget? Can they offer various products that fit your resources? Most contractors will give you bids for good, better and best options that include choices of products, design and aesthetics, prices, brand names/manufacturers and roofing services.
  • Do the roof contractors in Sonoma 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, when having a new roof installed, it may not be reasonable to expect an uninterrupted schedule or a quiet worksite. So talk with your roofing contractor about what you can reasonably expect while the roofers are working on your home. You are more likely to be satisfied with the completed product and the work while it's in progress if you go into the job with fair expectations.

The best roofing contractors in Sonoma County, including those in the larger cities of Healdsburg, Cotati, Petaluma, Santa Rosa, Rohnert Park and Windsor and even some in the smaller towns, can be selective about which roofing jobs they take. That's because not every roofing company is able to handle every kind of roofing repairs or roof installation job. So it's important to look for the high-quality roofing contractors that have the skills and ability to do the roofing work you're looking for.

Once you're narrowed down your choices by interviewing roofers, meet in person with the roofing estimator at your home for an on-site estimate. Discuss what you are looking for in your new roof or roofing repairs, and listen to their suggestions of materials and styles.

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.


Get a Detailed Roofing Contract from Your Sonoma County Roofer
Now that you've found the roofing contractor that's best for you, it's the perfect time to ask for a written contract that outlines the details of your roofing job. The contract should include the cost of the job, details about the materials to be used and installation information, such as the 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 Sonoma 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 Sonoma 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 responsibility 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 simple steps you can take to be a good customer when hiring a Sonoma County roofing contractor.

  • Be clear and upfront with the roofers. Let them know what you want from your new roof, the long-term outcome you're expecting and specific ways they can satisfy your expectations.
  • Before you hire a roofing contractor in Sonoma County, restate your expectations and goals, and reiterate to the roofing company representative your understanding of the agreement. Most problems with local roofers occur because of a breakdown 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 he will call you with updates.
  • Be sure the roofing company service representative can reach you at all times while they're reroofing your home or completing your roofing repairs. The work will move along more smoothly if your roofer can reach you for any necessary updates, questions or work authorizations.
  • When your contractor contacts you, return calls promptly to keep the roofing installation and repairs on schedule.
  • Pay for the roofing work promptly.

Why would you want to be a good customer? Roofing contractors in Sonoma 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 Sonoma 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 Sonoma 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.

  • Before the job starts, survey your property for any potential challenges that may make the job harder for the roofing contractors or that may add time to the job. This may include low hanging tree branches near the roofline, trees or shrubs that make it hard for the work trucks to enter your property or get close to the work site, or lawn furniture or ornaments that may be in the way of the roofing contractors. 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. Not only is it unsafe for your loved ones to be near the construction site, it also can also add time to the job if the roofers need to be cautious to avoid injuring pets or children. If you have pets that use the yard near the roof construction area, take them out on a leash while the roof installation work is going on so that the roofers don't need to worry about closing gates behind them.
  • Ask your Sonoma County roofing professional what you can do to simplify the job for them. In some cases, it may be easier for you to take care of tree trimming, roof cleaning or moving vehicles before the construction crews arrive and it may save you time and money in the long run.
  • Make sure your roofing company has contact information where 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.

The most common roofing requests for new roofs and roof replacements listed below are available in the larger Sonoma County cities of Petaluma, Rohnert Park, Santa Rosa, Windsor, Healdsburg, Sonoma, Sebastopol, Cloverdale, Guerneville and Cotati and all of the smaller towns and West County.

See the paragraphs below for the definition of each term.

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
Common roof repairs in Sonoma County including in the larger cities of Sebastopol, Santa Rosa, Petaluma, Windsor, Rohnert Park, Healdsburg 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. Most roofing contractors in Sonoma County provide emergency roof repairs and roof maintenance.

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
Unlike sloping roofs, 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 Sonoma 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 replacements are the 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
Whether made of corrugated metal or translucent fiberglass, roof panels 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.

Easy Ways to End Conflict with Sonoma County Roofing Contractors
You've done your due diligence by carefully choosing a qualified roofer in Sonoma County. But whether you're unhappy with the completed roofing work or there are communication problems, it's important to know how to best handle disagreements if problems or conflicts arise with your roofing company.

The easiest way to end conflict is to try to resolve the problem directly with the head roofer or the roofing company owner. Most local roofers are professionals who are proud of their company's reputation, so they try to keep customers happy. When talking with your roofer about problems, remember:

  • Discuss with your roofer any problems or disagreements right away. Don't wait until the roof repairs or re-roofing is done before voicing your concerns.
  • Remain calm and rational.
  • Sit down with the Sonoma County roofing company representative and review together your contract for roof repairs or roofing installation.
  • Document in writing and photographs any complaints or problems you're experiencing.
  • Set a deadline for resolution of the situation. You may withhold payment until the dispute is resolved.
  • If the response you get from your roofing contractor is less than satisfactory, consider hiring a local building inspector or roofing expert to assess the work.
  • Fire the roofing contractors as your last option. This can lead to lawsuits and work delays, so only fire the roofers if you feel you have no other recourse.
  • If you have serious problems with a contractor, you may file a complaint with the Contractors State License Board.

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.
