Excelsior Roofing is an OUTSTANDING company. I had a roof leak and I called several companies to inspect and recommend a fix. Excelsior roofing was the ONLY company that responded quickly and inspected the roof and provided a solution. They completed the work quickly and did a professional job. I would definitely hire them again! read more

Well I called this company to get a second estimate on the roof repairs about a month ago. A guy came out, mentioned that a "patch" would probably be sufficient. He left and I never ever heard back from them again. No estimate, no follow up, no nothing from them. I know it's not my job to call them to follow up with them. It's their job. I highly not recommend them. read more

I have been a customer of Excelsior Roofing for 11 years. From putting a new roof in to doing maintenance Mark and the team have been stellar. Excellent quality of work, great to deal with, prompt. Excelsior also has amazing customer service - if you are a customer they will come out and do inspection and minor service for free and only charge if work needs to be done. Unmatched. read more

I was looking for a company that could repair/replace both my metal gutters and the "dutch" gutter that runs between my house and my neighbor's house. This is a common thing in San Francisco - the houses are so close together there isn't room for a metal gutter, so they kind of extend the roof and make a tar and gravel thing that goes between the two houses. I didn't want the hassle of dealing with two contractors. Sunshine Gutters wouldn't do the dutch gutter, and so I went with Excelsior. They were nice, professional, clean, showed up on time for everything and all that. The small metal gutter they replaced in the back of my house is good, and the dutch gutter is good. My only complaint is that they said the front gutter only needed to be cleaned. I didn't think too much about that. Sounded fine to me. I didn't go out and examine my front gutter with binoculars which I should have done, really. Now that I *am* looking more closely I notice that the front gutter has many problems. I can see between the gutter and the roof, which means the rain is running down and not ending up in the gutter at all on one side of the house. The gutter has a bad rust area in one corner, and I notice a persistent drip (i.e. it evidently has a hole in it). Bottom line, I believe this gutter will need to be replaced and there probably needs to be some flashing (?) added so the water actually makes it into it. While I think us homeowners tend to worry that people we hire will tell us we need to have work done that we don't need to have done and we will get ripped off, there is another danger too. That is that when we are getting estimates we are told "that is fine, you don't need to replace that," which is always great news, but then...when a component of the work isn't included, the estimate comes in lower than someone else who said you DID need that work done. This is what happened to me. I want to emphasize though that I do like Excelsior Roofing and I would definitely call them for roofing work in the future, and they did all they said they were going to do, but I don't think they had their heart in the metal gutter part of my job. I'm now going to have to get more estimates and get the front gutter fixed, which is a drag. read more

EXCELSIOR'S EXCELLENCE EXCEEDS EXPECTATIONS! We had our re-roofing job done by Excelsior Roofing Company! They did an OUTSTANDING JOB with EXCELLENT WORKMANSHIP. The job was well planned, organized and executed beautifully by the owner, Mark Powers and his wonderful team! Great partnership between the two and they were very professional. Mark listened to our concerns and he took the time to explain everything in tremendous detail. He showed and told us the steps for the job and the materials being used. His interaction with us is reflected in how he treats his crew: listening, detailed, patient, understanding, careful and thorough. Caring Boss = Encouraged & Dedicated Crew = Great Workmanship = Happy Customers! Why tar and gravel? Besides Brer Rabbit, tar was an obvious choice since our old roof was also tar and gravel that lasted over 20 years without an issue. The new technology is probably good but I haven't heard of the same longevity as the tar and gravel method. Excelsior put out a couple of "No Parking" signs a few days before and our neighbors (mostly) complied. Then shortly after 8 AM, 5 huge black trucks rumbled up the street and the uniformed army arrived with shovels and brooms in hand. Immediately they started moving equipment, scraping the old roof down to the wood, moving supplies on the roof and worked like a bunch of bees. Everything was in concert, like a well-orchestrated movement. A lot of banging and scraping, old tar and gravel removal: somewhat un-syncopated but that's the roofing melody. Down comes the old stuff and up goes the roofing paper, tar, gravel, flashing and what ever else that's needed. Then the touch-up and incredible cleanup took place. Truly professional, friendly and nobody wore flip-flops. They finished about 80% of the work on the first day and completed all the detailed work by noon on the next. The work itself is quite impressive. The Spanish tiles were cared for and secured properly. The downspouts and bonnets all seem sturdy and were painted. The air well roofing was amazing and touts a new and much larger drain. The crew of 10 led by Mr. Eduardo, paid attention to details such as covering the two neighbors storage sheds and cleaning up afterwards. Each member of the crew knew their part of the job and worked hard together to get the job done well! We can't say "Thank You" enough for a job well done! So go have a new roof installed during the drought. Why not? I'm hopeful the 40 days and 40 nights of rain will happen soon or at least before the end of the 5-year warranty to really give the roof a test. Our house may float away, but at least our roof won't leak. Cheers! read more

I made an appointment with Mark to have him look at my gutters a few weeks ago. They called the day of that the estimator was sick - understandable. I rescheduled for the gutters to be looked at today and he showed up knowing he was looking at the gutters, went up on the roof then said they don't do gutters. Really inconsiderate that they wasted my time and now I have leaky gutters with the rain already starting. read more

We hired Excelsior Roofing to replace our skylight, as well as to do some general roofing maintenance. Everything went very smoothly -- they did exactly what they said they were going to do, and for the price they said it would be. The owner replied promptly to all my questions throughout the process. And the crew that did the work was great as well. read more

Fan-Tas-Tic. I had a small job on our roof and a fe contractors came and gave quotes. Not only was Excelsior Roofing's quote very reasonable, but they were pleasant, on time, and professional. What rubbed me the wrong way with most other contractors that they all seem to have found "sever problems" with the roof and offer their services to maintain and repair those problems. The interesting thing is that each roofer found different problems, and when asked about the other issues (that previous contractors found) they always said that that's not a concern. Excelsior Roofing was the only contractor that thought that the roof was fine and didn't require expensive repairs (we also had an inspector corroborate that.) In fact, when they were up there, without even saying anything, they touched up a few tiny spots at no extra charge. Now how about that for honesty, service, and plain good business? I will most definitely use them again when the time comes. read more

Honesty goes a long way with me. Instead of immediately trying to push me towards a costly re-roofing, Mark suggested a cheaper alternative to get me through the next 5 years. After calling 3 other roofing companies (2 of which didn't call back and the other failed to follow up with an estimate), he came out the next day to give an estimate and then fixed the leak the day after that. Granted it was a small job, but its hard to get roofers to even come out to your house unless they smell big money. I'll definitely call them back when its time to do the whole roof. read more

Excelsior Roofing went well above and beyond what was expected for a roofing company. We were lucky to book them ahead of last winter's rains and we were really glad we did. Out of the 5 bids I got they were right in the middle, but their quote was reasonable given the complexities of our roof (multiple pitched and flat sections). When our original install date got moved up, we happened to be out of town but this wasn't a problem for their crew. By the time we got back they had finished most of the roof and only needed another day and a half on the job. Mark was great in explaining exactly what they had done while we were gone (and even pointed out areas of dryrot that they went ahead and fixed on their own). They also replaced all of our downspouts for much less than I would have estimated, and even added additional drainage to divert excess water. Our roof, gutters, and downspouts worked perfectly during heavy rains and I have no doubt will last a very long time. read more

Excelsior Roofing has been our roofing company for many years. My family owns an apartment building in San Francisco, and we just had our second roof put on by Excelsior. The first roof (a flat tar and gravel roof) was put on 20 years ago, and started leaking in November. I called Mark and Bill, and they came out right away to check on the leak. Our building has settled over the years, and the water tends to pool in one corner, and that is where the leak sprung. The roof was at the end of its expected life, so we decided to have a new roof put on. There was a 2-3 month waiting list, but Excelsior removed the pooling water and put on a substantial patch to hold us over. The new roof was put on a few weeks ago. Bill came out the week before and went over what to expect during the job and he answered all my questions. The crew that came out did an excellent job. They were very professional and they obviously knew what they were doing. My contractor was working on some other jobs during that time, and he even commented on what a great job the roofers were doing. The crew was polite to me, my tenants, and my neighbors. What dust and debris was made (much less than expected) was cleaned up and everything looked ship shape at the end! The roof job was bit tricky, as we are on a hill, on a narrow street, and have a deck in front of the building. Also, the roof on one side needed to be sloped to the drains in the middle, so they needed to do some extensive building up of the roof. In spite of the obstacles, they did a great job. I am very happy with the work done by Excelsior and would not hesitate to hire them again or to recommend them. I didn't get quotes this time, but when we had the roof done 20 years ago, they were the best price of the six quotes we got. I assume that they are still very competitive in price. read more

I contacted Excelsior and Mark got back to me quickly. Eduardo came out to do the estimate and I had the details in an email the next day. I have worked with this company several times over the past 13 years and they are the only roofing company I call. They did a great job this time as they have done for me in the past. Highly recommended! read more

You get what you pay for! Yes, Excelsior is expensive, but they really do a great job. Mark, the owner, was so professional and helpful. I wouldn't have made it thru the rain without him. They're also an all union shop! That should still hold some merit in today's competitive world. read more

They responded quickly when I asked for a bid. They under promise and over deliver. The work was done in one day, and they clean up after themselves. read more

We had a tar-and-gravel roof that was more than 20 years old and leaking. I bid the job out and Mark's team was quick to come out and do the bid. They weren't the cheapest but they seemed like they would do the most professional job. They turned out to be professional as expected. Finding some of the concrete on the house had to be replaced, they called in a subcontractor. All was smooth and as up front as you could imagine. When there was a leak after the roof was put on, Mark was going to come over immediately to check it out before I discovered that it had nothing to do with the roof but a problem in our light well. I highly recommend Excelsior Roofing. read more

One of my skylights was developing some cracks around the edges. My neighbors suggested Excelsior Roofing company. Called to get a quote they were out the next day and 24 hours later I received my estimate. Price was good so they ordered the skylight for me. Took about 10 days and they came out and installed it for me. Excellent service foe a small job. When it's time to replace the roof Excelsior will get my business. read more

The one of the companies that I can trust on in San Francisco. Mark is a really kind and organized person and Bill checked our roof precisely. The crews, especially Marco is professional and super helpful. All of our issues have gone after they came! read more

A three-man crew from Excelsior just left my San Francisco home after completing a four-hour maintenance job involving tar and gravel (not the best material, of course, but that's what my home had when I moved in). The foreman, Lalo (Edward) was clear, professional, honest. In short, everything you would want. The crew repaired some poor flashing between our roof and our neighbor's home, and on the "brows" of our front facade, plus sealing all pipes/vents and light wells, and coating those with silver roof paint. They put tar and gravel on some "alligatored" areas of the roof and along its edges. They also found and repaired a few gaps/holes that we didn't already know about. I brought the men fruit, juice and chips and salsa and they were very appreciative of that. (I would have brought lunch but they left at around noon.) They definitely deserved it. All in all, I would recommend this roofing company to others. read more

After getting other quotes to replace my kitchen roof, I chose Excelsior Roofing based on their price, detailed quote, and 5-star rating on Yelp. I believe I made the right choice. Bill came and provided me with an estimate very quickly. During my five months of decision making, Mark Powers was very kind to answer all my questions. They even told me they start the work even before I got to paying them my down payment. Very efficient! Today, Raul and his team came on time and prepared with the permit, which they take care of, btw. I really couldn't see the finished work and I won't really know until the rainy season. However, I would like to review the customer service. Raul and his team were courteous and helped me move a huge furniture that was blocking their way. They kindly put it back for me after they were done. They left the work area neat (neater than before). read more

Apologies on the overdue review on the roof leak repair! Very quick responses via email, nice person that came by to do the free estimate of the roof leak repair, and quick quote price was sent to me within 48 hours. Please be nice and understand during the 2016 Jan/Feb there were a lot of people that needed roof leak repair. Excelsior Roofing can only fix the leak when there's a clear/dry day for their team to do the fix. Please be nice and patient with them as the fixes are dependent on Mother Nature. I would refer others to this very professional company. read more

Excellent roofing company. Mark Powers and his crew made the process painless. If your looking to replace your roof these are the guys! read more

Great response and efficient service. I had a roof leak and they were willing to take on a smaller project. Mark proposed a competitive bid along with Bill and the roofers completed the repair/maintenance on-time and within budget. I also think they did a few extras that weren't in the original bid. The results were clearly more professional than prior roofers and I have a 5 year guarantee. Would recommend and thanks. read more

Disclosure: I am writing this review based on the a single visit from Mark. I have not yet decided which roofer to use for my project. I live in San Mateo and I have a leak in my roof. Mark came down to the peninsula to provide a free estimate to either fix it or replace the roof. He arrived right on time and kindly spent an hour with me discussing the various options. He was candid in his assessment of how to save money on the project. In fact, he mentioned several ways that I could do the job cheaper by using other contractors rather than his own firm. I was impressed and grateful for his honesty. I highly recommend calling Excelsior. read more

Though booking far in advance is required, it's well worth the wait for the exceptional quality of skilled workmanship that Excelsior Roofing provides. Given his many years of roofing experience, owner, Mark Powers was concise in his estimate and detailed all recommended work at a competitive cost. Removal of an old roof surface followed by the Installation of a new tar & gravel roof on a main flat roof and side lightwell roof area was accomplished in one and one-half days by Mark's outstanding team of experienced craftsmen. The professional quality and customer care of Excelsior Roofing is deserving of the highest praise. read more

Excelsior finished replacing one tar and gravel roof and maintaining another at our home yesterday. The experience has been stellar from start to finish. Another roofing company (Standard) told us we needed a new roof THIRTEEN years ago. Excelsior came out twice since then saying that none of our 3 roofs needed to be replaced for at least 3 years (free inspections almost immediately after I called). I can't recommend EXCELSIOR highly enough. The scheduling takes a good long time, but they were honest that my ceiling wasn't going to cave in while we waited. Their crew was so professional and so friendly. Their work is just beautiful if one cares about the look of silver paint and rocks on the roof. Thanks to Mark and all the guys who came out yesterday. read more

I hired these guys to repair a roof in my home in Potrero Hill. It did take a few months, but it is worth the wait. I know when people have leaks, they would want someone to come out the same day and fix it, but not possible. It is much better finding a quality company, being patient, and then they do it right the first time. Thanks Excelsior! read more

My roof is about 14 years old and googled it about how long my bitumen modified roof would last. The internet says 15 years. So I emailed Mark and got an inspection done. The inspector said it would last another 3 to 4 years and its 20 years roof. The inspector explained to me in detail about the cracks on the roof and there is nothing to worry about. He recommended that I check in with them in a few years. What's really good about this company is that they do free inspection and great customer service and not to sell something you don't need. I thought I would need a roof because there are cracks on the seams but the inspector said no right now!!! I still get to keep my money ! Totally would ask this company to replace my roof in a few years ! Thank you again !!!! read more

I discovered Excelsior Roofing on Angie's List (sad to say Angie's List is gone), and they had one of the best records, if not the best record among roofing companies. Their professionalism is exhibited thoroughly by its president, Mark Powers and by Bill Powers, Excelsior Roofing's construction supervisor. I have mainly been in touch with Mark by phone and by email. His quote was reasonable and fair. As a customer, I found Mark knowledgeable, flexible and patient. I was very confident in what I wanted in replacing the roof on my house, and Mark was very cooperative in working with me. When it came to the actual work, Bill was in charge. Meeting with Bill you knew instantly this was the professional you wanted to oversee the work to be done. He too exhibited the same professionalism, skill and patience of his brother, Mark. The crew Bill led exemplified the skill and intelligence of their supervisor. Excelsior Roofing is all you would hope for in a roofing company. read more

Excellent response, prompt and efficient service. I knew we needed to have a section of our roof repaired, and when the roofer that originally quoted the job was unresponsive, i reached out to Excelsior. Mark let me know that they couldn't get to our job until after Feb, but they came out to inspect our job and gave us a reasonable quote (not cheap, but lower than the first quote). They also included other maintenance work on the roof, which i appreciated. Mark responded to my questions promptly so i fully understood the quote. Because we were a relatively small job and we hit a dry spell, Mark let me know they could squeeze us in before the end of the year. Surprisingly he called the next week to tell us they could do our job the following day. The crew arrived on time, were very efficient, and showed me pics of the completed job. It looks great and we're ready for the rains! Thanks Excelsior! read more

In a nutshell: I called them. They IMMEDIATELY called me back. They set an appointment for an estimate. They were on-time. They told me what I needed. More importantly, they told me what I DIDN'T need (integrity!) They gave me a sound and reasonable estimate. They showed up on time, did beautiful work and cleaned up before they left! (and p.s. thanks for trimming some trees back "just because" it would make my gutters last longer - - now that's customer service!) Excelsior will be my roofer from now on! read more

Our roof just needed some maintenance -- we had a couple small leaks around vent pipes and the roof needed to be repainted. The estimate was clear and thorough and the estimator was pleasant and easy to communicate with. They gave me practical recommendations that were in-line with the excellent inspection I had when I purchased the home a few months ago. I'd had another estimator out earlier in the day that I couldn't communicate well with, and that didn't listen to what I wanted. They gave me an estimate for a whole roof replacement, which wasn't what I was looking for. (We can easily get a few more years on the roof, and want to integrate the roof replacement into a remodeling plan) Anyway, Excelsior scheduled an appointment a couple weeks out, but had a last-minute cancellation and pinged me to see if they could come by and do the job early. They banged it out in a couple hours, were super polite about some initial confusion (my wife wasn't expecting them and totally grilled them -- thinking they were the other roofing company trying to pull a fast one on us), took before and after pictures and beat the big storm that rolled in later that week. We haven't had any leaks since, and the roof looks great. read more

Excelsior reroofed a small section of our roof to solve a problem with a leak at the sliding glass door that opens onto the roof. They recommended a contractor who removed the sliding glass door so that Excelsior could extend the roofing underneath the door (which is how it should have been done in the first place). They showed up on time, cleaned up after doing their work, and seemed to do a good job. It's summer now, so I'll find out in the rainy season how the work holds up, but it should be good. read more

Can't say enough good things about them. The estimate was fair and Bill elaborated on the "what's and why's". The work was done on time, with care and very professional. Good supervision. I was impressed with their attention to detail and their clean up operations. The scaffolding went up and down on time; which has not always been my experience with others using scaffolding. Payment operations was smooth as well. All around painless and positive read more

Mark and his team are superstars... They did a small job for me in the mission and were professional from beginning to end... Extremely happy with the outcome... As a native San Franciscan, I can say they understand what San Francisco business was once upon a time....proud of their work......thank you. read more

Rogelio & and his crew did outstanding work replacing our tile roof. I would highly recommend Excelsior roofing, and would work with them again. read more

Excelsior Roofing - Roofing Near Me - San Francisco, California

These guys are honest and professional. I received a quote from these guys while going through escrow (since the roof was 30 years old and I knew I would immediately need to replace it once I bought the house. I knew it would be at least a couple of months after I bought the house before I would actually replace the roof since there were a number of other items wrong with the house that had to be fixed before addressing the roof. I had been given a $2,500 credit toward repairs and I was told that I needed a roofing company's name to close but that I can change the name to another roofing company upon close and that the check will be held until I authorize the issuance. Since Excelsior Roofing was the only company I received a quote from (it's hard to get 3 quotes when you don't yet own the home and have limited access to it), I gave Excelsior Roofing's name and address. Well, my nitwit Escrow Officer accidentally cut the check and mailed it immediately upon close. Mark from Excelsior Roofing called me and let me know he had received and cashed the check before realizing that he hadn't done the job. He then offered to mail a refund and answered additional questions I had about roofing. I offered to pay him an accounting fee for his troubles, admitting that my budget was tight and I was still planning to price shop so I wasn't sure if I'd be using him, but, he declined, explaining that his company never asks for that large of a deposit anyway (they usually only ask for enough for permit fees and some materials) and that giving back money on a job that was never performed is the right thing to do. I was taken aback by how honest and professional he was and received the refund within 2 days of the call! I wouldn't have even known that a check was issued (my Escrow Officer was claiming ignorance about the check being released) if it wasn't for Mark. Mark was even honest about pricing, telling me that his company is about mid-range in price and that I will find cheaper and more expensive contractors out there as well as giving me a ballpark of price ranges he expected I would get. I did get a couple of other quotes and decided to go elsewhere due to pricing differences (hence the minus one star) but would have loved to use Excelsior Roofing if my wallet wasn't so tight. I'll just keep my fingers crossed and hope that the roofing contractor that I chose will be as honest and reliable as Excelsior Roofing was in my dealings with them. read more

After many years of fantastic service, my roofer retired. This is one those happy, sad news events in you life. If you're a home owner in SF, a quality roofer you can trust is really important--for your peace of mind, and your property's life span. After a long, serious search--many roofers telling me I needed a new roof (mod bitumen is not the standard any more)--I settled on Excelsior--"the roof is older but years away from replacement". From the owners to the crew, they are honest, professional, and do beautiful work. They extended the life of my 20 year old mod bitumen roof by at least 5+ years with a perfectly executed day of roof maintenance. When the time comes for a new roof you know who I'll call. Highly recommended. read more

Unfortunately, overall, I am quite disappointed. Two years ago, we had three quotes to re-do our whole roof. It was not an easy roof because it has a lot of different slopes and weird angles. We had three quotes, one was twice the other two, so we decided to go with one of the two lower ones, which was Excelsior. Especially because it is considered one of the best in town. They did the job in two days. I am far from an expert, so I can only say that it looked nice at the end. However, with the first rain the kitchen hood started pooring water over the stove. Excelsior came back right away (they are really responsive) and they said things had not been done really really right and needed to be fixed, which they claimed they did. The next rain we had the same problem. So, they came back a second time to fix the previous fix. So, far things are holding at the hood. However, we discovered just recently that a gutter that they said they would have taken care over the roof (a place i cannot access easily) they actually did not. The gutter is super-rusted beyond imagination and needs to be changed. It was rusted even two years ago but i guess they decided to skip the difficult repair and tell me it was all fine. read more

I have only good things to say about Excelsior Roofing. This company has handled my roof repair job very well. Everybody was organized, on time and the work product was excellent. I highly recommend this company. read more
