Carlos Rodriguez: Close to Home

By James Florence, Diamond Certified Resource Reporter

SOUTH SAN FRANCISCO — After he graduated college, Carlos Rodriguez was on the cusp of a promising career in the corporate world. However, when a need arose at his family’s roofing company, he opted to apply his administrative abilities closer to home. “My dad started Mr. Roofing in 1989, so I’ve been around it since I was about four years old,” he says. “I went to UC Berkeley and took a business management job after I graduated, but then my dad called me and requested my help with his company. We came to an agreement that I would take care of the sales and customer service side while he would handle the production. With my prior education and experience, I was able to implement my knowledge of customer service and business management toward improving the company’s operations.”

In 2006, following his father’s retirement, Carlos assumed ownership of Mr. Roofing, Inc. Today, as president and CEO, he says his favorite part of his job is its inherent versatility. “I appreciate the fact that I’m not always cooped up in an office; rather, I get to run around and meet a lot of really interesting people from diverse backgrounds. And, of course, I enjoy taking in some great views while up on our customers’ roofs.”

Carlos was born in Mexico and came to the United States with his family when he was three years old. Today, as a resident of South San Francisco (where he lives with his wife, Teresa, and their two children), he says he enjoys being part of the local community. “It’s pretty cool to run into my customers while out and about and receive a warm greeting.”

Outside of work, Carlos says the majority of his favorite pastimes involve sports. “I really enjoy sports because they demonstrate the greatness that human beings can achieve.” In addition to playing basketball with friends and attending Golden State Warriors games, he enjoys being a spectator at his children’s sporting events. “My son, Ladislao, plays football for Junipero Serra High School, and my daughter, Nayeli, plays for the San Bruno Storm, a traveling softball team that I help coach. I love to watch them compete—they make me proud.”

In his life and career, Carlos finds inspiration in a quote from Henry Ford: “Whether you think you can, or you think you can’t—you’re right.”“I think one of the biggest obstacles most of us face is our self-induced limitations,” he explains. “If you go into a situation expecting to fail, it’s a lot more likely to happen than if you believe in yourself and maintain a positive attitude.”

When asked the first thing he’d do if he could retire tomorrow, Carlos says he’d seek out new opportunities to touch the lives of others. “In my current career, I enjoy educating my clients and coaching my employees in regard to accomplishing our goals, so if I retired tomorrow, I would probably get into teaching, coaching or another field that would allow me to inspire and motivate others.”

Chris Testa: A Sure Trajectory

By James Florence, Diamond Certified Resource Reporter

SAN FRANCISCO — After four decades in the roofing and construction industries, Chris Testa has no regrets about the trajectory his professional livelihood has taken. “I started working in construction while attending college in the ’70s, and from there I got into roofing,” he explains. “What I like about roofing is it’s the finishing touch to any building—it serves both as the protection for the overall structure and its crowning architectural detail. Few people dream of getting into roofing when they’re a kid, and I certainly didn’t, but I ended up here and I’m quite happy I did.”

Today, as sales manager at Sure Roofing & Waterproofing, Chris says his favorite part of his job is meeting and educating homeowners. “Most homeowners don’t know anything about roofing—they look around their neighborhood and that’s their only reference point. That’s why I enjoy educating our clients on roof design and construction, as well as helping them pick products that are going to meet their needs and provide the aesthetic effect they’re looking for.”

Born in England and raised in Canada, Chris resides today in Reno with his wife, Melissa. Outside of work, he spends his time on a variety of hobbies and pastimes. “Growing up in Canada, I played ice hockey and still enjoy playing it today,” he details. “I also do architectural design as a hobby and enjoy doing small projects on my home. Right now, I’m designing a solar roof—I’ve been working on that for a couple of years now.” Additionally, Chris likes taking trips to visit his family. “I have three grown children and four grandchildren. They’re spread out all over, so I do a fair bit of traveling to see them.”

In regard to his professional career, Chris says it’s all about providing solutions. “As a salesperson, I want to be sure that what I’m offering to my clients is going to provide them with real, effective solutions. That’s why I take the time to educate my clients—I want to empower them to make the right choices for their roofs and homes. Ultimately, my aim is to be a problem solver, not just a salesperson.”

When asked the first thing he’d do if he were to retire tomorrow, Chris says he’d fulfill a longtime fantasy. “I would run to the ocean and throw my cellphone out as far as I could. No joke—that’s exactly what I’m going to do when I retire. After that, I’d probably split my time between visiting my family and being a beach bum.”

Ask Me Anything!

Q: What was your first job?
A: Delivering newspapers when I was eight years old.

Q: Music or talk radio?
A: It depends. When I’m driving, I often listen to talk radio; when I’m at home, I usually listen to music.

Q: Did you play any sports in high school?
A: I played badminton and wrestled.

Q: If you could time-travel, would you go to the past or the future?
A: I would probably go back 20 years and buy stock in Google and Microsoft.

Q: What’s your favorite snack?
A: Coffee and a truffle.

Mike Im: An Early Start

By James Florence, Diamond Certified Resource Reporter

PACIFICA — Mike Im’s roofing career got off to an early start thanks to a family member who worked in the industry. “I got into roofing because of my uncle, who had his own roofing company,” he explains. “I was fortunate to learn the process of roof installation at a young age. At first, I mainly worked with my uncle during summers, but after I turned 18, I began doing it full time. I became very focused on refining my skills and knowledge, and within three years, I teamed up with my dad to open our own roofing business. We ran that for 28 years until my father passed away. After a couple of years of transition, I opened Im Roofing Company in 2018.”

Mike says his favorite part of roofing work is the craftsmanship it entails. “I love the art of roofing. I’m a perfectionist when it comes to my work, so everything has to be uniform and look good. I take pictures before, during and after each job, and it’s very satisfying to look back and see the transformation we were able to make happen.”

A resident of Pacifica (where he lives with his wife, Woo Kim, and their two sons), Mike likes to spend his time outside of work with his family. “My kids are my best friends, so I love hanging out with them,” he says. “Before I know it, they’re going to be all grown up, so I try to spend as much time as I can with them. On the weekends, we like going to the movies, fishing, jet skiing and doing other fun activities.”

As a roofer in the San Francisco area, Mike appreciates the diverse character of his workdays. “There are so many different architectural styles here in the city, which keeps things interesting,” he says. “You have pitched roofs, flat roofs, tile roofs…some homes even have shingle roofing up front and a flat roof in the back. Some architectural styles are more challenging to work on than others. For example, Victorian homes are pretty difficult to work on, so we have to set up scaffolding around the perimeter to ensure safety.”

When asked the first thing he’d do if he were to retire tomorrow, Mike says he’d visit another continent. “I would probably take my family on a European vacation. A lot of people say they’d go to Hawaii, but I’ve already been there many times. I’ve never been to Europe, and my wife has always wanted to go.”

Ask Me Anything!

Q: What are your favorite sports teams?

A: The Golden State Warriors and the San Francisco 49ers.

 Q: What’s your favorite restaurant?

A: Outback Steakhouse.

Q: If you could time travel, would you go to the past or the future?

A: Neither—I’m happy to stay in the present.

Q: Do you collect anything?

A: I collect cars.

  • What is my budget for roofing repairs and reroofing?

What To Ask In Person

  • How much time will the roofing job take, from ordering the shingles or roofing materials through new roof installation?
  • Will I be able to stay in my home during the roofing process?
  • Is the new roof energy efficient? Will it reduce my electric bills?

  • Do you have customer references I can call?
  • Are you responsible for warranty work or roof repair services if there’s ever a problem with my new roof or reroofing?
  • What can I do to make the roof installation process easier?
Read moreRead less
  • What To Ask References
    Ask Previous Customers About Their Experiences with Local Roofers in San Francisco

    It’s best 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 roofer in San Francisco 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 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 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 San Francisco 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? Were they avoidable from the contractor’s end?
    • Did the roofing company employees show up on time?
    • Did the employees clean up after finishing the window installation?
    • If you need a new roof or roof repairs in the future, would you use this roofing contractor again?
    • Would you recommend this roofing company?

  • Review Your Options
    Find and Hire Good Roofing Contractors in San Francisco, Including the Larger Neighborhoods of Sunset District, Bernal Heights, Richmond District, Mission District, North Beach, Tenderloin, Pacific Heights, Excelsior, Nob Hill and Bayview District

    The Diamond Certified symbol has been awarded to companies that scored Highest in Quality in an accurate ratings process.

    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 San Francisco for your roofing job, it’s important to consider the following questions:

    • Can the roofing contractors meet your needs for scheduling, new roofing products and roof installation method preferences?
    • Are the San Francisco roofers knowledgeable on the roof products they sell and install?
    • Can the roofing contractor explain which roofing services and roof products best suit your needs and why?
    • 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 San Francisco offer warranties in the event of a product failure or installation error? Will they guarantee the work in writing?

    You may also want to examine your expectations for your new roof and roofing work, realizing that some may be impossible or not feasible. For instance, with new roof installations, it may not be reasonable to expect an uninterrupted work schedule or a quiet process. 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 if you go into the job with fair expectations.

  • How To Work With
    How to Get Reliable Roofing Repair Estimates from San Francisco Roofers

    The best roofing contractors in San Francisco 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 training to do the roofing work you’re looking for.

    Once you’ve interviewed some local roofers, meet in person with the roofing contractors you liked best 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 compare several estimates, but you’re wise to limit it to a small number of estimates

    from the best roof contractor candidates. That will let your roofers know that you’re looking for good service and fair prices rather than cheap roofing services. This will also improve your chances of finding a roofer who provides the best quality workmanship on roofing installation and roof repairs.

    Sign a Contract For Roofing Services With Your San Francisco Roofer
    Now that you’ve found the roofing contractor that fits your needs and can perform the roofing work, ask for a written contract that outlines 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 San Francisco 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 San Francisco 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.

  • Be a Good Customer
    Ways You Can Be a Good Roofing Company Customer

    It’s your 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 San Francisco 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 San Francisco, 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 San Francisco 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 San Francisco
    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 San Francisco 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.
    • Ask your San Francisco 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.
    • 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.

Check The Work
Look Over the Completed Roofing Work

Once your roof repairs or reroofing is completed, most good roofers in San Francisco will give you a written invoice that lists the completed work. This invoice may include:

  • The name, business address and license number of the roofing company.
  • A detailed list of all work done.
  • An itemized list of roofing products and roof replacement parts used.
  • The total cost for the roof repairs or total reroofing, including the amount due for labor.
  • Written proof of all warrantees and guarantees provided by the roofing manufacturer and roofing installers.
  • To be sure that all the work lives up to your expectations and the contract, ask your San Francisco roofing contractor to walk through the job with you and show you the repairs and reroofing while you check the completed work against the invoice. Take the time to ask any final questions about the work and get additional information for maintaining your new roof.

Written Warranties
Get Written Warranties from San Francisco Roofers

Ask for written proof of any warranties and guarantees before your roofers leave the job and you give final payment. Not all roofers back up their work. But if the roofer you’ve chosen guarantees their work, they should give you written details, including:

  • The roofing company name and physical address.
  • The work and products covered, including whether the roofing company will repair or replace the roofing products or give you a refund if you have a warranty claim.
  • Your responsibility if you file a warranty claim, such as if you have to pay for labor when filing a claim or pay a prorated amount for repairs.
  • The terms on your new roof warranties.
  • If the roof warranty coverage is transferrable to the new owner if you sell your home.
  • All exclusions and limitations must be in writing.

Top 10 Requests
Top Service Requests of Roofing Contractors in San Francisco

The most common requests for new roofs and roof replacements explained below are available in the larger San Francisco neighborhoods of Richmond District, Mission District, Sunset District, Tenderloin, Bernal Heights, Excelsior, Nob Hill, Pacific Heights, Bayview District and North Beach and all of the smaller neighborhoods. 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 Roofs
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 imitate the appearance of slate shingles, wood shingles and tile shingles with the strength and toughness of steel roofing.

Roof Repair
Common roof repairs in San Francisco including in the larger neighborhoods of Nob Hill, Sunset District, Richmond District, Tenderloin, Mission District, Bernal Heights are required to fix poorly-installed gutters, roof leaks, missing shingles, roof flashing leaks, skylight flashing, roof valley flashing, roof ridge vent damage, gutter problems and nail holes. Most good roofing contractors in San Francisco provide emergency roof repairs and roof maintenance.

Roof Shingle Installation
Roof shingles are 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 San Francisco. They are long-wearing, unique and often sustainable roofing options. Roofing tiles are available in styles, including flat tiles, imbrex and tegula tiles, Roman tiles, mission or barrel tiles, interlocking roof tiles, and interlocking pantiles.

New Roof Installations
New roof installations 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. 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 common choice for homes, greenhouses and patio covers. Metal roof paneling comes in a variety of colors and styles to match any decor. Roof panel installation is often quick and attractive, and the lightweight panels are a good choice for commercial or residential roofing.

Frequently Asked Questions
Roofing Contractor FAQ

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.
