“Customer satisfaction is very important to us, so we always make sure each client is happy before moving on to the next project. We’re not just trying to make a quick dollar—we want to build long-term relationships with our customers and earn their trust so they recommend us to their friends and families.”

Im Roofing Company provides a wide range of roofing services for residential and commercial clients in San Francisco, the Peninsula, the East Bay, and the North Bay. In addition to installing, repairing and replacing all types of roofing systems (including tile, torch-applied and composition shingle), the company is qualified to help its customers with specialized work like Title 24 compliance applications. President Mike Im says Im Roofing Company’s honest approach to roofing has been critical to its success. “Integrity and honesty are important to us—they show through in everything we do. We truly care about our clients and their projects, so we tell them what to expect from beginning to end and do whatever it takes to keep our promises.”Im Roofing Company believes in educating its clients about the details of their projects so they can make the right decisions for their situations. “We want our customers to have a good understanding of the roofing process by the time we’re finished with their jobs,” affirms Mr. Im. “We understand their roofs are big investments, so we focus on educating them the right way.”

Maintaining customer satisfaction is a crucial aspect of any business, but it’s even more important for roofing companies that have earned the prestigious Diamond Certified award. For Im Roofing Company, the key to keeping clients happy is simple: take the time to make sure they’re completely satisfied before moving on to the next project. “We want to build long-term relationships with our clients, so their happiness is our number one priority,” affirms President Mike Im. “We’re not trying to make a quick dollar—our goal is to provide them with high-quality, cost-effective outcomes.” Im Roofing Company has been providing roofing services for residential and commercial clients in San Francisco, the Peninsula, the East Bay, and the North Bay since 2018. The company has the training and equipment to install, repair, and replace all types of roofs, including specialized systems like tile, composition shingle and torch-applied. Unlike roofing contractors that take a “hands off” approach to informing their clients about the specifics of their roofing options, Im Roofing Company considers consumer education one of the hallmarks of its business. “A new roof is a big expense, so we make sure our clients have all the information they need to make the right decisions,” says Mr. Im. “For example, in San Francisco, commercial buildings are required to use Title 24 compliant material, which is also known as ‘cool roofing.’ We help our clients understand their Title 24 options and help them choose products that are right for their properties.” Another distinguishing attribute of Im Roofing Company is its dedication to finding and solving difficult issues that many roofing companies aren’t qualified to handle. “We love to troubleshoot,” confirms Mr. Im. “By drawing upon our decades of industry experience and roofing knowledge, we’re able to look at the bigger picture and find the real source of the problem.”

Q: How quickly can you start my roofing project? A: Sometimes we’re backed up for three to six months at a time, depending on the weather, but we can usually come out and perform some repairs on your roof to keep it functional until we can replace it. Q: What could happen if I don’t maintain my roof? A: Maintaining your roof is crucial. If you neglect it, you could get interior water leakage, which can lead to mold issues. Q: Do I have a choice for flat roof applications? A: There are two different types of materials for flat roof applications: acrylic and TPO. We prefer acrylic because it seals roofs and makes them waterproof. Q: What should I know about the roofing industry? A: Just like with any industry, some roofing companies just want to make a quick dollar, but others are passionate about the industry and want to do quality work. It’s up to you to do your homework and find out who you can trust. One bad roofer can ruin the reputations of many, so we always recommend getting more than one estimate.

Take precautionary steps to ensure your roof lasts as long as possible. Having a new roof installed on your house is a significant investment, so it’s important to understand the various environmental factors that can negatively affect its performance and lifespan. Ultimately, the type of roof you choose for your home should complement your particular environment and surroundings. Consider the following tips for dealing with common roof problems: Condensation Condensation is the result of a buildup of warm, moisture-filled air. If your attic is inadequately ventilated, it can cause condensation to decay the wood sheathing and rafters, which will eventually destroy the roof structure. To ensure your attic is properly ventilated, have a roofing contractor install larger or additional vents that cause the air temperature in the attic to match the outside air temperature. Moss Once moss starts growing on moist wood shingles and shakes, it traps even more moisture on a roof’s surface and causes rot. The best way to avoid the possibility of moss growth on your roof is to trim back trees and bushes that create damp, shaded areas. Keeping your gutters clean is also important, as it ensures proper drainage and gives moss less chance to grow and thrive. Shingles In order for a roof to be effective, it needs to be completely protected by high-quality shingles. When shingles become too old or are torn off by wind, the roof’s structure becomes vulnerable to water damage and rot. A deteriorated roof only gets worse as time goes on, so it’s important to have any missing or torn shingles replaced as soon as possible. Flashing Without high-quality, tight flashings around your roof’s chimney, skylights, vents and junctions, water can enter your home and damage your ceilings, walls, electrical systems and insulation. Have a professional conduct a roof inspection twice a year to ensure your flashings are in good shape.

PACIFICA — In the past, roofing shingles were warrantied for a set number of years depending on their quality grade. For example, you could get a “30-year shingle” or a “40-year shingle.” More recently, the industry has shifted to a different standard, wherein all shingles come with “limited lifetime” warranties regardless of their quality grade. A limited lifetime warranty generally covers issues caused by defective shingles; however, since the payout is prorated depending on the shingles’ age at the time of the claim, homeowners rarely get reimbursed for the entirety of their investments, especially if the defect doesn’t happen for 10 or 15 years after installation.
It’s important to be aware that although all modern shingles come with limited lifetime warranties, they aren’t all of equivalent quality. The fact is, 30-, 40- and 50-year shingles still exist—they just go by different names now. Most manufacturers offer different quality tiers for each of their shingles. For example, the CertainTeed Landmark® series starts at the base tier and moves up through Landmark Pro, Landmark Premium, and Landmark TL. Each tier varies in weight, thickness and performance, but they all come with limited lifetime warranties.
One potential problem with all shingles having limited lifetime warranties is that it opens the door for unscrupulous roofers to take advantage of homeowners. Under the guise of installing a “lifetime shingle,” a deceptive roofer could charge for the highest tier product and then install the base tier product while the homeowner is none the wiser. When the roof’s lifespan ends up being much shorter than expected, that homeowner stands to lose a lot of money. That’s why it’s crucial to know exactly what you’re getting when having a new roof installed. Do your research and make sure your contract lists the exact product that’s being installed on your roof.

Roofing Shingle Warranties: What You Need to Know

PACIFICA — Mike Im: Composite shingles manufacturing industry has changed. Shingles used to have 30-year, 40-year, and lifetime warranted shingles. Now all the shingles are lifetime warranted. It’s very, very important that you ask the contractor what type of shingles, lifetime shingles, they’re actually installing. Thirty-year shingles used to be called “landmark.” Forty-year shingles used to be called “pro.” Lifetime warranty roofs were called “TL Presidentials.” You don’t want them to tell you they are going to put on lifetime warranty shingles and charge you for a TL Presidential shake price and actually install a thirty-year shingle; there’s a big price difference in that. So you have to make sure that you ask the contractor, “What type of shingle are you actually installing?” Very, very important.

Video: Warning About Roofing Shingles

<h1>Mike Im: An Early Start</h1>
<h6>By James Florence, Diamond Certified Resource Reporter</h6>
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.
