I would avoid giving Master Roofing Company any stars if I could. We are dealing with a recurring roof leak that this company refuses to properly fix without trying to price-gouge us. The roof was originally installed by them in June 2023 with a 5-year workmanship warranty. We bought the house in November 2024, and the roof leaked immediately during the December 2024 rains. Their team came out and attempted a repair in early 2025, which proves they initially acknowledged responsibility. However, the exact same leak reoccurred in the same exact spot during the December 2025–January 2026 rains. The underlying issue was never actually fixed. When we contacted the owner, Danny, he completely shifted goalposts to evade the 5-year warranty. He is now claiming the warranty is non-transferable simply because the house changed hands. We have thoroughly reviewed the original contract, and there is absolutely no clause stating the warranty is non-transferable. When we asked him to provide the specific written terms to back up his claim, he couldn't do it. Instead of honoring their workmanship, they sent us an outrageous repair quote. They are trying to charge us $6,250 to fix a very small, isolated part of the roof—even though the original invoice to redo the entire roof was only $7,250! Charging nearly the price of a brand-new roof for a tiny repair is absolute extortion. Getting them on the phone is almost impossible because their voicemail box is constantly full, and emails are routinely ignored until you threaten legal action. They have left us with no choice but to take this to small claims court and file an official complaint with the California Contractors State License Board (CSLB). Avoid Master Roofing Company. They do not stand behind their workmanship, they use fake loopholes to void their warranties, and they will try to scam you with thousands in repair fees for their own defective mistakes.
These guys saved us - our insurance dropped us and we had to get a new roof before the rains and before we were uninsured! They came to our rescue, came in on time and on schedule and were completely professional. Would use them again in a heartbeat and encourage everyone else to do the same!
They repaired a part of my roof that another big company messed up and refused to fix. Sunny and his team fixed it, and also patched another problem on my roof at a good price. I didn’t know they were a local small business as they had been referred to me by a neighbor so I was extra happy that not only were they great but I was supporting a nice Oakland built business. Highly recommend them for your roof needs.
With some 30 roofs providing shelter over our property portfolio, my Partner and I have regular need for roofing services. Several years ago our favorite roofer fell out of favor. A realtor friend suggested we consider Master Roofing for our next project. Our first engagement resulted in the installation of a carefully crafted membrane roof which replaced a failing tar and gravel roof, on a single-story, 4-plex in Oakland. Master Roofing owner, Sunny Kwon’s, work ethic, attention to detail and commitment to his finished product, quickly became apparent. Sunny’s focus on delivering a professionally installed roofing system is directly related to his own high integrity and sense of personal responsibility for his roof's performance. Our second experience with Master Roofing was also a smooth one. This time, Sunny installed an asphalt-shingle roof, with Dutch gutters, on our 1920’s Bungalow. His attention to detail around the integrated gutter design gave credence to our belief that we’d found our new regular roofer. On Presidents Day 2017, after weeks and weeks of record rainfall, I called Master Roofing, hoping to leave a message asking for a favor on a property in which water was actively spilling into three levels of finished living space. Sunny actually answered the call (maybe I have his mobile number!) and offered to meet me at the property within minutes. During a steady rain, Sunny inspected the high roof, determined the cause of our problem and made a recommendation. Without question, we needed a full roof replacement, as soon as there was a predictable dry period ahead. Like an answer to one’s proverbial prayers, Sunny’s next project was delayed, the rain paused and by working into the dark until the job was water tight on the second day, he beat the next major storm by only minutes. It all happened so fast and the surroundings were left so tidy, that it didn’t seem like we could possibly have had a new roof installed. This all happened at a time when roofers were in extreme demand and over-booked for weeks to months ahead. Having recently received two 3rd party-generated roofing estimates for this particular roof, not only was Master Roofing’s immediate and accommodating response without compare, it was also the least expensive proposal by a significant margin. So, whether you need an urgent repair or full roof replacement, I highly recommend that your first call be to Master Roofing. Sunny’s professional, responsive demeanor and friendly, positive attitude, will change your attitude about calling contractors. Sunny’s high quality workmanship and commitment to his finished product’s performance, plus his reasonable pricing, will leave you feeling quite serendipitous.
Sunny and Danny did an excellent job fixing our roof a few years ago and it has aged extremely well. Their pricing is incredibly fair for the high-quality work that they provide and the extremely efficient work ethic! I highly recommend master roofing!!!
