Recommended Customer Reviews

I hired Knox Roofing to inspect the roof of a house I planned to buy and they told me the roof was just fine. Thank goodness I had a contractor look at the place and learned that the roof under the deck was leaking very badly and that the roof and the deck both needed to be replaced. My realtor said it looked like Knox did a drive by review. Terrible! Don't trust them!

I went to Knox for recommendation and installation of an attic fan for my home. I went with a fan recommended by them and had it installed. After hooking it up and turning it on, it was horribly noisy. Knox was immediately responsive to the issue and assured me something was wrong and they would take care of it right away. After receiving a new fan they had me listen to it before coming out and installing it. Once they did the noise completely went away and it works perfect and quiet. Turned out there was a defect in the original fan.
Things happen when your dealing with moving parts to no fault of Knox's. What I was very impressed with was the response. Their was no delay in admitting something was wrong and immediately acknowledging it and taking care of the issue. They truly stood behind the product and their work. How refreshing in this day and age when quality service is hard to come by. From the office staff to Bill the installer and Warren himself, an excellent and pleasant to work with team! In 10 years when my roof is going, I know who I am calling.

I called Knox Roofing repeatedly to find out if they were going to complete a job they started n Nov. 2014. The job was to replace the 2nd of 2 shingles that had fallen off. I was charged $290 for one worker who replaced one shingle that I supplied. I did not receive any refund for the work not done.
Warren Knox, the owner, came to ""repair my roof"". He would not listen to me regarding the shingle problem. He offered a refund yet never provided that refund, and he was belligerent throughout the meeting.
Warren Knox wrote a letter to me accusing me, a woman in my eighties, of basically intimidating him.
The negative comments of other reviewers are also my experience. Seek out another roofing company, because Knox is not an honorable business man...and he is afraid of senior citizens.

We hired these guys and the roof they built leaked the VERY FIRST TIME IT RAINED...
and continued to do so until we hired someone else to fix their horrendous job.
We asked them to come out and fix their work but
they VOIDED THEIR WARRANTY without cause.........we should of taken them to court......an attorney said we could of easily won but it simply wasn't worth the hassle.
I now have a friend who is an inspector for the county and he says (off the record) that my experience with them is not uncommon. He says their work is so bad that he fails most of the jobs that they do. I wish I had known this before I wasted a large amount of money with knox roofing..
I love k-pig but every-time I hear one of knox's ad's I want to puke (but my love of the pig is so great that I never change the station), Luckily the next guy was far more honest and did a good job AND he was cheaper.

I have used Knox Roofing one time. It was a while back. I am calling them out for a re-roof on my house. I do a lot of roofs, because I am a property manager, but, luckily, I haven't had to do any since 2011, when I used Knox to roof a small but very difficult commercial building. I am writing this review now because I believe the proof of a great roofer is not what it looks like a week after the install, but what it looks and works like four or five years down the road.
The roof Knox put on for me, and I think they did the gutters too, looks as new as the day they finished the job. Knox is at the top of my call list, and I will use them again.
As a business owner myself, I can tell there is an angry ex-employee or crazy competitor getting their friends to write bad reviews to try to harm this business. I know quite a few slime bag roofers in the area that wouldn't hesitate. You can always tell when Yelp is being abused by some crazy or someone bent on revenge, there are no reviews between 1 star and 5 stars. If I am not mistaken, all of the other reviews are 5-star, and that tells you something.
The building Knox roofed for me was a real bear, a combination of membrane and conventional composite shingles, with HVAC and mechanical in one five-foot deep flat-roofed well, plus another larger two-foot high flat-roofed well with an entry hatch, drains, gutters, etc. Knox was on the ball and professional from day one to the finish. The price was competitive and the materials were exactly the high-quality I specified. They even noticed one of the membrane liners had been made wrong by the fabricator and they sent it back. They could have just put it on and I would never have known. They demonstrated some real ethics.
I trust Knox based on my experience. I think Knox is being too kind in their responses to the one-star fakers. They should just tell the fakers to call the office. If the fakers are a real customer, I am sure Knox will work it out. Knox is the most professional and legitimate roofer I have ever worked with. Just go by their showroom and see for yourself.

Purchased a Lifetime Roof from this company and the price was same or below other quotes. Very professional crew and company, timely and clean. Identified and repaired any and all needed repairs, before laying the roof, the GAF Camelot shingle.
I am very happy with the work done and would choose them again and again!
Luckily, this is a lifetime roof! Thank you Knox Roofing!

Knox Roofing just completed installing a roof on my home in Pacific Grove on 213 Granite St. Their crews were effecient, polite, orderly and installed a beautiful roof. Knox Roofing delivered on all points and more. Could not be happier!

This review comes a good 3 or 4 years after Knox Roofing put a new roof on our Soquel home (adding a couple of skylights in the process, which are great).
To get 5-stars, clearly there haven't been any leaks, but my story is better than that. We have house with high, open-beamed ceilings. Looking up you see the beams and some faux tongue and groove plywood -- but above that it was tar paper, cedar shake, and sky! As is common in Santa Cruz, there was absolutely no insulation. Needing a new roof, I thought that this might be a good opportunity to improve on the situation...
I began calling roofers and they began visiting. To each I asked how we might get some insulation with our new roof. I spoke to seven or eight companies and, admittedly learned a little each time. By the time Warren Knox showed up I was close to knowing what we wanted -- but he improved the design a little more and, instead of making me feel like I was going a little overboard, Warren's attitude was, ""we can do that""!
And they did. Not the cheapest (but right in there), not the fastest (better good than fast) but, they hung in there and found a way to get it done. The results are fantastic. Our insulated roof makes our home MUCH more comfortable and the raised soffits -- that we worried would look too thick -- make our house look much more substantial and nicer.
New roof, new skylights, 12"" of rigid insulation, and the way Knox got it done shows the depth they have in their company. Highly recommended.

This is why Yelp is a waste of time. We had Knox roofing fix one roof after other roofers could not stop the leak. Then we had Knox replace two other old roofs. The county inspector said his job is easy when he has to inspect a Knox roof. He knows it'll be done right. Three roofs, no leaks, no problems. A little bit more than others but you'll know the job will be done right. If you have a problem talk to Warren and he'll make it right.

Knox replaced our roof in Jan 2012. They were prompt in both getting us a price and in doing the work. The crew was fast, pleasant to have around and did a great job of cleaning up afterwards. We're very pleased with the result. The only problem we've had in 1.5 years was a small leak in one of the gutter corners their sub-contractor installed. This was fixed promptly. We highly recommend them.
