Jon and his team at Keller Roof Co. repaired my wind damaged roof today and the results are excellent. We have used Keller Roof Co. in the past and have been always been happy. I have recommended Keller Roof Co to relatives and friends and they all agree that Jon and staff are excellent technicians and charge a fair price. read more

Jon Keller Roof Company CA State License # 741945 909-980-8075 I'm kind of cheating in writing this review, because I've had the advantage of a few satisfied neighbors who have used Jon Keller to remove all their concrete tile and re-paper their roofs. I want to start by saying I have learned the hard way to do my research before laying out hundreds--or thousands of Dollars. Jon Keller is the best there is--Bar None... We own a two-story home with a very steeply pitched roof. The last winds threw a broken tile off the roof. I decided to assess for additional damage and found a couple more broken tiles, some that slipped, and dry rot in an outer corner. It had been repaired by a handyman a few years ago. The handyman I had hired only replaced a couple feet of facia in each direction which meant that the spliced boards now gave little support for the weight of the concrete tiles--resulting in a bad droop and the return of dry rot. This time, I was determined to hire a proper roofer to do my repairs, so I called Jon Keller. Attention to details: Jon used some of the best quality lumber I have seen in a very long time. I pre-painted the wood before having him install it--much easier than painting overhead after install, and it wraps all end-grain. As it turned out, I had 13 broken tiles and a couple of rake-tiles missing. Every time I've talked to a roofer about replacing tile on my 32 year old house, they warned me that they could not get the same tile--not made anymore. Jon has hundreds of my exact tiles (Gray Super-shake) in stock--he has them in brown as well. I watched as Jon carefully removed quite a bit of tile, the old spliced facia boards and shiplap underlayment boards. He thoroughly cleaned the areas to be repaired by blowing off all the dirt and debris buildup before beginning to re-install the facia and tiles. Jon replaced 20 feet of facia with 1"by 3" cleat to repair my drooping corner and several shiplap pieces. He carefully removed the old boards at previously spliced areas without damaging the wood that had to remain in place. He replaced all the wood, slid new paper under the old, sealed where necessary and was very meticulous in making sure the roofline and corner were perfectly straight. Jon and his roofing partner walked my entire roof, replacing broken tiles and blowing all the pine needles and debris off the roof that had built up over a few years. They sealed and painted all the pipes, corrected the runoff of a poorly placed rain gutter, and to my amazement, Jon checked every single one of my rake tiles--hammering in nails that had worked loose. I felt he had done quite a lot of work for the $900.00 I spent tuning up my roof. Jon Keller is a licensed professional with decades of experience. He started exactly when he said, worked hard and finished the same day. I will call him for all my roofing needs from now on. Jon does All Types of roofing--by the way... Most sincerely, Bruce Wilson read more

John is no joke. He's old school .. and I WILL TAKE IT! someone in the business of doing roofs for 30 plus years is all i need. I've had John out 2x for minor repairs, but when the Fontana wind practically blew our roof off, John was the one who answered our call. His works is great, he's professional, on time and the nicest guy. I really hope I never have to do business with him again .. lol thanks John for fixing us up! read more

John is uhhhhmazing ! He repaired a previous shotty roof repair that caused water damage inside our home. He did an OUTSTANDING job and we will never have to worry about our leaky roof ever again. He is meticulous & reliable and his fee was very very reasonable! He finished in one day. Thank you John!! read more

We're completely satisfied with the roof repair work done for us by Keller Roof Co. Jon (owner) is an old school pro and brings 30+ years of experience to the job. He's involved personally in the work. No BS, no upselling, no shortcuts. He clearly explained what needed to be done. His price was excellent and he was on-time for everything from providing an estimate to starting the repair to completing the work as scheduled. Definitely recommend. read more

Was a little disappointed. Asked Jon to inspect our roof and give me an estimate for any repairs needed. Didn't have a leak issue just broken and loose tiles. Got his estimate and decided to go with him. My issue was there was an area that he worked on but I felt he did not complete. All the tiles in that area were cemented so nothing could get through but the 3 tiles Jon adjusted. When I addressed it with him he stated that wasn't part of the estimate (which I found confusing, his estimate stated to reset loose tiles with sealant, not sure how this differed). Apparently cement is not part of that. He was willing to come back at an additional charge but we declined. read more

John did an excellent job and paid attention to every detail! Love our new concrete roof!

We had a few slipped and cracked tiles on our roof due to the constant beating it receives from the wind here in Fontana. I reached out to Keller Roof Co in addition to another contractor with good reviews here on Yelp. I chose John at Keller Roof Co for a few reasons: 1. He is a true tradesman and would be the one who would actually be doing the repairs. 2. He didn't come off as "salesy" and try to upsell me on other "suggested" preventative maintenance. 3. He set the expectation up front in regards to turn around time, scheduling the repair date and follow up (I called right after a crazy wind storm so he was pretty busy), and came through with the finished result that exceeded my expectation in the end. John will be my first call next time any repairs are needed on my roof. read more

John did an excellent job fixing my skylight. He was very professional and prompt and actually had a real license. I would highly recommend.

I recently contacted Jon Keller regarding a leak in my garage. Jon came out the same the day, found the leak and provided me a reasonable quote. Due to the recent Covid-19 work restrictions, Jon was able to schedule me in as soon as possible. Jon took appropriate precautionary measures and his work was professionally done. He not only repaired the leak but he also did a thorough maintenance on my roof that included replacing broken tiles, blowing debris from the roof, checked every single one of my rake tiles-hammering in nails that had worked loose and sealed areas where it was needed. Overall, i feel Jon and his roofing partner did a excellent professional job for what I paid for. I'm very happy and satisfied with the work that was done to my roof. I highly recommend Keller Roofing. read more

I noticed all the great reviews and thought he doesn't need another review stating how honest, reliable and reasonably priced he is, but I have to anyway because he made me feel secure about the job he did fixing my roof. He will always be the first and only one I call if my roof leeks ever again. Thank you John!! read more

Excellent service and price! Jon inspected, gave me an estimate, and completed the work on my roof without us ever even meeting! Def recommend them read more

Had John out to repair a hole in my roof. Very good guy. Excellent work. Fair price. I'd recommend Keller to anyone.

Jon and his crew just left after doing a great job on repairs to my roof. They removed tiles and replaced rotted plywood and facia braces, added new felt, sealed seams and vents, and then replaced all the tiles to 2 sections of my roof. I agree with all the other comments on here. He gave me a fair price, he was knowledgeable, friendly, on time, thorough and super clean. I highly recommend him and would use him again without hesitation. read more

We hired John and his crew and are very pleased with our experience. John did a great job of communicating and they were punctual. They repaired several spots on our roof and did a fantastic job of cleaning up!! Very reasonable pricing too. I wouldn't hesitate to recommend Keller Roof to friends or family! read more

This review is a bit late, Mr. Keller worked on our roof mid June of this year. I got a couple of quotes from the few roofing companies that actually responded to my inquires out of the 7 that I contacted. He was the only one that actually went onto the roof to inspect it, and had the most reasonable price for the work that needed to be done. Jon was knowledgeable, polite, and professional, and did an amazing job. With the crazy winds that we get, several tiles had been loosened or blown off the roof throughout the years and needed replacing or adjusting. The tiles on our HOA neighborhood house are hard to come by, but luckily Jon had the foresight to stock up on them years ago. Jon also replaced a vent cover that had blown off who knows when, and re-sealed around all the vents since the previous sealant had cracked and deteriorated over the years. He also reinforced the the shoddy work the previous roofers had done and blew the debris off the roof, and now our roof looks fantastic! Very happy with his work and will definitely call him again should the need arise. read more

Jon is great he came down and looked at my roof for some needed repairs. He gave me a good price on replacing 20 shingles resetting other and some other much needed preventive maintenance. It was done quickly shortly after the agreement for repairs was submitted. read more

Just had our patio roof redone. John Keller always on time, reliable, and reasonable. You can expect quality work and product!

Rocky M John Keller is my Roofing company I call on every time we have a new Project or repair read more

I received many compliments from family and some neighbors who noticed the work results. Excellent work Jon!!!

Used Keller Roof Co from a suggestion from a different site. Called on a Monday, he came on the next day, was more than on time, friendly, efficient, and got the problem solved in a good time. I also felt he was honest and didn't try to tell me "other" work was needed. 5 stars from me. Definitely my go to roofer from now on. read more

Had some tile that were slipping and one broken tile. Not knowing who to call, so looked up Keller Roof Co on Yelp called him up and had no problem to give me a fair bid. Nice man and was on it, so if you have roofing problems call Jon he'll take care of it. read more

I really can't say enough about Jon, the man is honest, knows his profession, and makes a stressful situation like a leaking roof much easier to deal with. I discovered a leak during the numerous rain storms California received in 2019. I found Keller Roof on Yelp among four other roof repair companies which were all rated highly in the area. I called for quotes and discovered that I was not alone in my predicament and that roof repair had a list 3 months long with everyone I spoke to. Jon was the last of the four companies I spoke with for a quote and he was able to provide me a competitive price, background information, and not leave me feeling like I should expect hidden costs upon completion. The thing that really impressed me about Jon, that stands out in my experience with dealing with other businesses in general; is that: 1. He came out to inspect the roof while he was sick just so he could provide a potential customer a speedy solution to a leaking roof. 2. On the day of the inspection, we ended up talking for a bit about a few things not directly related to my roof nor a profit; but I could tell he was honestly engaged. Just one human being offering advice to another. 3. He had a lot of other upcoming jobs and so the wait list was a few months out. Although it rained almost daily and I was in a hurry to get the roof fixed ASAP; I never called to pressure him since I knew he would get to me as soon as he could. He managed to squeeze me in a few weeks earlier than anticipated!! 4. Unfortunately the day he was scheduled to come out, we had some very high winds - just my luck. John was kind enough to call me early and ask if it would be ok to reschedule for the next day... to my astonishment he was asking, and not telling!! He was willing to sacrifice his safety under adverse weather conditions just to keep his word... WOW!! Of course I easily agreed but it really speaks loudly to the type of person he is! 5. Lastly, he finished all the repairs within a single day, and managed to include extra square footage of repairs at no additional cost... he just did it since he was already up there and wanted to help out a customer! I waited a few weeks before writing the review to see if I would discover any leaks but I am happy to say that Jon's work is top notch, and everything is back to be dry inside! I can honestly say that Jon has a new life long customer for any new repairs that I may need as the rest of the roof ages. Jon and Keller Roof Co. have earned a perfect score as far as I'm concerned!! read more

I'd give 10 stars if I could. Jon was awesome. Such a nice guy. I had a cracked skylight that made me really nervous when it rained hard. I called 10 other companies and they all said the job was too small or they didn't call me back at all. Jon did an awesome job installing my new skylight and fixed some broke tiles and a pipe while he was up there. He was also was very patient with us after we bought the wrong skylight and wasted his trip. And he's very comparably priced and always returns your calls. You won't be sorry with Keller Roof. read more

John Keller and his crew did my roof last September. Complete tear-off, new fascia and a number of replaced deck boards. Because my house is in a historical district, extreme care was needed it both the carpentry and choice of materials. John worked with me to insure that the materials used matched the materials replaced - at times requiring custom milling. The roof came out beautiful, the carpentry was excellent - and as such I won a grant from the local historical society. John was always there when he said he would be, always did what he said he would do and always cleaned up before leaving for the day. Unfortunately I will not ever need to use John's services again, but if I needed a roofer, without hesitation I would call John. read more

Jon has done a fantastic job on our roof. I'm highly satisfied with the results and I'm proud of the roof we now have. John is an expert at making repairs and found problems with our roof I didn't even know were there. He could have easily roofed over the problems but he did honest work for us. I'll post some pictures, but our roof looks the best on the street. No sloppy work and everything get's cleaned up daily. read more

Keller Roof gave me a very competitive price, showed up when they said they would and charged the amount agreed on. I will use them again if needed. Easy to work with. read more

Jon came out and re-sealed all my pipes on the roof, and replaced 15 tiles, and reinforced all the eaves for the windy season. Came out and did the job as planned and was reasonably priced. read more

Shows up every day at 0645 and leaves at 1700. Hardest working roofer around. Beautiful fascia and roof. Fully licensed, do your research. read more

Scott Z. Jon Keller and his crew repaired several large sections of my tile roof yesterday and found the source of leaking in the ceiling and fixed it.They were here when they said they would come, great workmanship, a very honest hard working person and they cleaned up everything. He even does a lot of the work himself, not just supervising the crew. While he was up on the roof he even sealed some roof vents and fixed some broken tiles so we don't have problems in the future. He returns all phone calls and even came back after he thought he had finished to do caulking he had forgotten to do earlier. His quote was very fair and I highly recommend Jon from Keller Roof Co. This is the first Yelp review I have written and Jon from Keller Roof highly deserves this 5* rating for his honesty and hard work to get the job done right the first time! read more

Kelley showed up on time and did a fantastic job. He even did some small repairs which was not in the contract for free. The price is reasonable. I would highly recommend him to everyone. read more

Jon has done roofing & repairs on my homes for several years and I always call him back, because he does a great job at a fair price. Jon always gives me a written quote of damage and repair valid for 30 days. read more

John did a great job in repairing a leak from our roof. He was very prompt and thorough repairing my roof. He's very fair & accurate in his estimate. I definitely recommend him for any minor repairs on your residential roof. Very professional & friendly and always responded back to my phone calls. read more

Jon did a fabulous job on my roof, it looks amazing. He placed dormer vents, and replaced areas of dry rot. He made sure that I was always informed on the work, down to the nails. I would and am recommending Jon to get the job done right!!!! read more

Jon knows his business. He was punctual and did a great job "tuning up" my roof Reinstalled broken and missing tiles, checked roof vents, blew debris from roof and checked rain gutters. Clean up too! I will recommend to everyone who needs a professional roofer. Thanks Jon & crew GREAT JOB!!!!!!! Kathy T read more

Jon was knowledgeable, communicative, and did a fantastic job redoing our roof! Always returned our calls promptly, and was very polite and friendly. Highly recommend his services! read more

My experience with Keller Roofing was definitely five star! From the quote, to Jon's work ethic, to the final product (my new roof is gorgeous), I couldn't have asked to work with a better roofing company. Jon Keller is definitely the hardest working roofer out there (works from 6:45 to 5:00 each day). He is passionate about his craft and it shows in his results. When I was getting quotes last March, Jon recommended that I hold off until the summer months because my new shingles would have a better chance of surviving, since it was still wet winter and the Santa Ana winds were still present. He didn't want to see me waste my money. I greatly appreciated his honesty because none of the other companies I received quotes from shared this same information with me. I highly recommend Keller Roofing. You won't be disappointed. read more

Great job! Jon does his own work and doesn't hire out day laborers like another roofer I know. Jon came out and repaired/replaced over 500sq. ft. Of my roof that had a leak due to to poor workmanship from the last roofer that was here. My wife and I now have peace of mind knowing that our roof won't leak. Jon went above and beyond what needed to be done and did a super clean up. Thank you!! read more

Called Keller Roofing last week. John told my wife he was coming to give an estimate on roof repair today at 1:30 PM. It's 6 PM, and still no call, no show. Business must be really good, so I suppose they don't care if they lose customers. read more

Jon came to my house on a Sunday to inspect my roof and gave me a very fair estimate. He told me at the time that he had a lot of jobs lined up already due to the rain but would get my job done by Jan 31. In spite of our seemingly ongoing rain, he got the job done for the price he quoted and never once tried to oversell me. He and his team cleaned up afterwards and he gave me some advice about my impending house painting project before he left. The next time I have a roofing need, I'm calling Jon back. Integrity type of guy read more
