FIVE STARS!! West Coast recently replaced my roof, and I couldn't be happier with the results. From the initial inspection to the final cleanup, the entire process was handled professionally and efficiently. The crew arrived on time each day, worked diligently, and paid attention to detail. The new roof not only looks great but has already proven its durability during the recent stretch of bad weather--no leaks or issues at all. The office communication was outstanding and answered all of my questions. read more

With the last two big rain storms in SoCal, we had water dripping through our kitchen recessed lighting. Two families in San Marino referred West Coast Precision Roofing. I called right before Christmas Eve and was able to get scheduled for the first appt on Saturday, December 27th between 7am and 8am. The lady scheduling was kind, professional, and fit us in quickly, as I'm sure everyone calling is stressed out about a leak. I had already read all their great 5-star Yelp reviews mentioning the owner, Mike, as well as the foreman Vicente. Vicente showed up with a big friendly smile and was able to immediately find the source of the leak. He was able to repair on the spot, as well as carefully inspect our entire roof. His communication skills and knowledge were excellent, in relaying missing shingles blown off as well as parts of the roof that had incorrect materials installed - risking future leaks. We always love supporting local small businesses and look forward to receiving their estimate on other repairs. We are grateful that this minor leak issue was repaired today by Vicente! read more

We chose West Coast Precision Roofing to change the underlayment of our roof. We have a 2-story Tudor with a high pitch on the roof, so this was a complex job. Michael Sanders gave us a competitive quote with an accurate time estimate for completing the job. We liked that West Coast was a local company (Montrose) and they had already done jobs in our area. We also appreciated that he didn't try to upsell us and clearly laid out the different options. The crew arrived on time each day and worked diligently. Michael took care of issues that arose. We are very happy with our choice and would hire West Coast again without hesitation. read more

Michael and his team did a great job. Michael was transparent and honest about his pricing and the crew replaced our roof in just over a week. Would definitely recommend them for any roofing needs. read more

We had a full tile reset on our main house an casita, TPO on our deck and torch down on our flat roofs. Michael Bierman provided a timely detailed quote. He promptly responded to all of our calls and questions. Precision finished on time and did an outstanding job. Great crew and supervisors with a high level of craftsmanship. The crew cleaned up the site daily and were respectful of our property. It was a difficult job on a hundred year old home. Highly recommend their company and crew. read more

Unfortunately, I have to revise my review. After roof was completed in Spring of 2025, we experienced a major leak in early 2026 ruining an entire wall of our home and resulting in the beginning of mildew/mold. Michael was unwilling to accept any responsibility for the damages even after an independent waterproofing specialist was engaged to uncover the issue and discussed it with him. I had to hire a different roofer to correct the issues (who also concurred with the water proofing specialist) and file a complaint with the CSLB. If you have no issues, then Michael is fine. But the second there is an issue, he is not great to deal with. That, in my opinion, shows that his true character is not great. If he had fixed the issue and helped fix the damages to my home, I would have remained a happy customer. Unfortunately, that was not the case and I think that speaks volumes about working with him. It's not the mistake, it's how it's handled. You've been warned. Also, note, he will refute this...look at all his other 1 and 2 start reviews. Very defensive. read more

new roof weathered first rain like a champ! micheal, monique & vicente (sales/business office & pm) were all easy to communicate with & made themselves available for anything that came up... work crew did the job better than last roofers & addressed all areas of concern for us. thank you all, will recommend without reservation read more

I couldn't be happier. I had a longstanding problem with the roof and gutters resulting from the original design of the home a century ago. Owner Michael Sanders understood the problem immediately and gave choices about proceeding. They fixed the problem, replaced a portion of the roof, and arranged for all of the gutters to be replaced. Foreman Vicente was excellent - he routinely kept me advised about plans and progress. He never spoke to me without asking about any questions or concerns. Their staff was professional. read more

Best in the biz, highly dependable, trustworthy, and does good work. Don't make the mistake I did and try to look elsewhere. You won't regret hiring them! read more

I highly recommend West Coast Precision Roofing. The company is honest, has high ethical standards, experienced staff, provides outstanding service, and prices are very reasonable. Monique who schedules residential work is professional, kind, experienced, knowledgeable, listens well, and is an excellent role model for customer service. My house had a leak through the skylight dome during the heavy rains before Thanksgiving. The next day West Coast covered the skylight to prevent any further leaks. Angel and Kevin completed the skylight dome leak repair and were respectful and communicated well. Mike Sanders (owner) hires and trains the best people who do the highest quality of work. West Coast Precision Roofing is a trusted local business if you live in the La Crescenta/Montrose/Glendale area but also has a wide service area in Los Angeles County. Consider West Coast Precision Roofing for your roofing issues. They are the absolute best! read more

Mike Sanders has been great to work with. His team was really responsive and worked hard through the hot days. I truly appreciate their professionalism and work ethic. The roof turned out great and Mike did a great job on the newly sloped flat roof, which was a tough project. The garage roof and pitched roof with Spanish tile also turned out great! Best of all, Mike worked through a tough situation with me and was very reasonable. That is something I really respect and I'm grateful he is so customer centric. I highly recommend West Coast Precision Roofing! read more

Michael, Vincente and their team were great to work with. Very helpful, good communication and the roof looks great. Highly recommended!

Awful service and dishonest contractor with bad quality work and taking shortcuts. It started with getting the job quote 1month late,which is unacceptable. Installed new shingles on pitched roof of house and workers walked all over roof when removing old roof and installing new roof. This caused flat section of roof to be damaged and leaked with first rain storm . It leaked inside upstairs in 2bedrooms unit and ceiling had to be repaired. Also never provided pictures with plastic sheet on top of bare wood roof. took every short cut possible to get the job done quickly. Left nails everywhere on ground that we had to clean up. Had to tell him many times to put the TV antennas back on the roof and finally that was done. had to tell him to attach the cable he removed back to the roof. and it was done.Overall sloppy and bad quality work..Contractor from hell and will never hire him again. read more

West Coast Precision Roofing is first rate. Mike Sanders and Dustin made our roofing experience effortless. Our roof is absolutely beautiful and we could not be more happy with the job. Each phase of the job was done by professional and courteous crews. Their workmanship and skill set showed they take pride in their work. Our property was always protected and left clean and ready for the next days crew. I highly recommend Mike Sanders, West Coast Precision Roofing to anyone who is in need of a new roof. Thank you Dustin for answering any question within minutes. I feel that our family gained more than a new roof but a new friendship. You guys are amazing. Sincerely Yolanda B. read more

Mike S. and his team are truly dedicated to providing quality and thorough work. Mike himself performed an initial inspection of my roof during a recent rain storm, provided suitable options and his team completed the work promptly and properly. A great experience all around. Thank you WCPR! read more

Honestly, really good people at this company. They worked on my neighbors house and I experienced an issue as a result. Nothing major and nothing that couldn't easily be remedied. I let them know about it. They respectfully listened and offered a reasonable (agreeable) response and then followed through in a timely manner. No arguing. No push back. No blaming. I really appreciate how they handled the situation--it tells me a lot about their values as a company. AND (btw), my neighbor was really pleased with their work! If you are stuck in making a choice, use West Coast Precision Roofing...you won't be disappointed. read more

I am so pleased with the work and professionalism of West Coast Precision. Mike Sanders is so responsive and cares about his customers. He hires quality people and ensures they will carry out the projects with integrity and technical skill. Mike is honest and will tell you the truth about the work needed to be done or what is not necessary. He knows many products and in my case he recommends TPO roof for a flat roof. They are good problem solvers and trouble shooters as well if repairs are needed. Mike and the company are high quality and can be trusted. They really saved me from any leaks and water intrusion during the Los Angeles rains. They did very comprehensive repairs to a terrible roofing job done by another company. Thank you so much West coast Precision!!! read more

I requested a quote online for a complete roof replacement. Mike came out within a few days and provided an estimate of the work needed. He was thorough and looked at parts of the roof that other companies did not. His estimate was fair, not the cheapest, nor the most expensive. However, we were impressed by the time that he took with the estimate and the level of detail that was included. Scheduling the roof was easy to do after choosing the color. The entire project took about a week and we are very pleased with the result. The team was efficient and the work executed on time as promised. Everyone that we dealt with was professional and polite. I highly recommend West Coast Precision Roofing! read more

Have had West Coast Roofing come out twice in the past 4 years. Very professional, honest reasonable and on time. Extremely satisfied read more

The back room in our house had a leak. I called to get 3 separate estimates. The first 2 suggested replacing about 300 square feet of roofing on my house. I was quoted over $2500 with the first two companies. It seemed like they did not want to take a smaller job so they over quoted me on a repair. I decided to call one more company and found Michael at West Coast Precision Roofing. This was the best thing I could have ever done. He actually pointed out where the water leak was coming into the back room and explained why the leak happened in the first place. The old owners of the property had a handy man who improperly installed 4 skylights that were way to close to each other causing water from rain to come in and damage the inside of the room. We decided to remove 2 skylights and repair that small section of the roof which was cost effective vs replacing the roof over the entire room. They also went over the entire roof and resealed and painted all the plumbing air vents and anything else that could cause future water damage! I'm a long time yelper and a pretty good judge on who do hire when it comes to getting home repairs done. If you're looking for a professional roofing company that cares about their clients Michael along with his installers at West Coast Precision Roofing in LA Crescenta Montrose is a super honest and reliable. read more

These guys are fantastic. I asked for proposal costs to stop a leak coming through our patio. After inspecting our roof, Mike Sanders submitted two bids to us, one for just fixing the leaks and trouble spots, and also informing me of the current condition of my whole roof, how soon I would need to replace, and what materials and warranties go with it. I went with the original plan to just fix the leak, since we were in the middle of a kitchen remodel. They kept in touch with me to let me know when to expect them, (Like any good roofing companies, they are busy after it rains here), and when they did the work, they touched on a lot of spots on the roof that might cause problems in the near future. Money well spent. And like I told Mike Sanders, I will see them next year to install my new roof! read more

Mike and his team at West Coast Precision Roofing are prompt, courteous and go the extra mile. Back in October he performed a repair on my roof section that has Spanish tiles. Quote was fair and he noticed some broken tiles in another section that needed to be replaced. These are old tiles and hard to find but he located a source and made the additional repairs at no additional cost. Highly recommended! John read more

I was very impressed with Mike S when he came to asses my roof. Of the 9 roofers I consulted, he was of the two who immediately identified that my aging tile roof was installed over wood shake shingles. I appreciated how thoroughly he explained my options. While I ultimately hired the other contractor, who is closer, I would still recommend WCPR as a candidate for your roofing needs. read more

Living in a house with a flat roof has its challenges, and not all roofing contractors know how to properly and efficiently add a new roof to a mid-century modern house like we have. I called a half dozen roofers who all gave me various prices, roofing options and ways to add to the value of our house, but Mike at West Coast Precision Roofing was the only roofing contractor who seemed to really understand how to do a flat roof properly, and his company easily got the job. The roof is amazing, West Coast Professional Roofing added insulation we never thought we could ever get with a flat roof, the materials and quality of installation are top notch and I know this roof will last for a long long time. I recommend West Coast highly, especially if you happen to live in one of the Webster Wiley homes we have up here in La Crescenta. read more

We reached out to Mike from West Coast Precision roofing to do an overall roof inspection on a place we had just purchased. We knew the roof needed work to begin with; he came out and gave us two options at two different price points. We ended up going with a full roof replacement at the end of the day but really appreciated the fact that he gave us multiple options, his thoroughness, candor, and professionalism. The job was completed quickly and within our tight timeline prior to us moving in (despite a 1.5 day delay due to a freak rainstorm). The guys came out and covered the roof in plastic the day before it rained. 5 stars for the great communication, honesty, and hard work ethic. Thanks Mike and the team at West Coast Precision Roofing. read more

West Coast Precision Roofing is the bomb! In less than a week, we received a price estimate, repair and clean-up. Our job was relatively small, but it was important to us and handled quickly, efficiently and professionally. We would use West Coast Precision Roofing again. Ruth S. and Richard R. read more

Fixed my leaky roof Called to see if it was fixed Prices were fair read more

2019 had one of the worst rainstorms in CA history. Two parts of my roof were leaking due to previous contractor's improper repair. I was panicking calling every roofer on Yelp to fix it. However, as one could image, all the good ones were booked up for weeks due to the rain. To my surprise, Mike's team was able to squeeze me in between the raining days and fixed the worst of the two leaks in a day. Their team removed the roof tiles and showed me where the previous contractor did wrong (bad to no caulking around the corners) and fixed the problem. It rained the next day, and no leak! That's the only proof I need! It rained couple more times since and the inside of the house stayed dry. The team came back when it stopped raining and fixed the other leak for me. One surprising thing was that after the job is done, they actually took out a giant magnet to pick up all the loose nails & screws lying around the job site. My previous contractors never did that, Mike's team actually picked up their screws and nails as well. I am an engineer by trained, so I really appreciated them showing me where the problems were instead of the usual "trust-me" from other contractors. Rebecca the office manager kept me informed on the schedule and availability of the crew, thank you for that as well. Overall, Mike's team is prompt, professional and good at their work. I'm glad I went with them! read more

We called Mike during one of the recent storms due to a new leak we discovered in our bedroom ceiling. Mike was able to squeeze us in during an extremely busy time for his business which was a huge relief. His team quickly fixed the problem and it doesn't appear that we've had any leaking since. He and his team were friendly, professional, and reasonably priced. read more

West Coast Roofing did my complicated roof some years ago and today did a mini check-up after the recent storms. I got several estimates the first time around. My experience couldn't have been better. My previous roof (about 75 years old, 6 layers deep!) had to come off, so it was a huge messy job. I was impressed at how neatly they were able to strip off the old roofing, with no damage to landscaping below or mess left behind. They cleaned up every day. Mike also took extra time with me to match the color of the flat part of the roof to the shingles. I'm glad I have a roofing company I can rely on! read more

It was time to replace my roof as it was 30 years old plus I was hoping I could get a roof that would help to keep house cool during hottest times of the year. I talked with 8 roofers/contractors before I met Mike Sanders. He offered me some great options, a fair price and his roofing experience along with being local in my community made him the best choice for me. I was very impressed with all the people I came in contact with at West Coast Precision Roofing. They listened to me and took action on my concerns. Everyone was friendly, professional and did a terrific job. Mike's Project Manager Bill was great - onsite everyday and answered all my questions and made the whole experience easier than I expected. My roof is beautiful and efficient. I highly recommend West Coast Precision Roofing. read more

I highly recommend West Coast Roofing. They were professional, courteous and thorough with their effort to fix my leaking roof and what would be considered a "small job." Most of the time homeowners only need roofers under duress- when their roof is leaking, needs to be repaired, or replaced. It's hard to find the best roofing company match for honesty, quality and fair pricing in this little known contracting area, but West Coast Roofing ranks up there. Mike Sanders and his colleagues were very good at assessing the chronic leaking problem with my roof (installed many years prior and not by them) clear with their description of work and addressing it with a solid solution. read more

I just had a new roof put on my cute little house and I used West coast Precision Roofing and my experience was FANTASTIC!

I HIGHLY RECOMMEND these people. read more

These guys are amazing! I noticed a leak when it started raining and I called them and Mike came out and fixed it. He was nice, honest and reliable. I hope I won't need him again but if I do, I find comfort in knowing who to call. Thanks West Coast Precision! read more

The team showed up when they said and finished promptly. They also helped us figure out a great less expensive alternative to replacing my entire roof. read more

We just had our 20+ year roof completely redone and Mike and company were terrific! They got the permits and kept us up to date on inspections and how the work was going. We had a rain delay the first day, but it was complete in about a week!!! Local company and they really seem to care about what they are doing. Great job!!! read more

From the first meeting with Mike Sanders to the final inspection of our new roof, West Coast Precision Roofing was a pleasure to work with! Dustin was very knowledgeable and answered all of our questions with expertise. Both Mike and Dustin responded quickly to texts and took care of all the little things that came up quickly and professionally. I was very impressed with how well the crew cleaned up a HUGE mess after teardown of the old roof. Super happy with West Coast Precision Roofing! The new roof looks amazing! Highly Recommend! read more

ZERO STARS. One of the worst home improvement service I have ever experienced. In fact the worst experience I have had for any industry. Not only terrible customer experience with no returned phone calls or not even showing up for some appointments, but not following through with agreed upon scope of work. They even had some self acknowledged defects in their quality of installation but wanted to charge extra to fix their mistakes. I heard the company was ran much better when the father was around. The son has no respect the customer or for the reputation his father built. I wish I read this review before I gave them work. BE WARNED! STAY AWAY!!! read more

Outstanding personal service. Great price for the excellent work. Willingly got us many samples till we got the exact roofing materials we wanted. Our roof turned out to be more of a mess than we expected with a lot of repair work to be done and Mike's team did it all. The roofers were hard working and friendly and they cleaned up each day amazingly well. Mike was on site numerous times to inspect the work and go over things with us. He was always available for questions--extremely responsive. Great people to work with and great results. read more
