Very happy with the work done on our house. Chaz came out and gave us a competitive quote and we hired him. His staff was very professional and worked hard during all the installation during some very cold weather. When they were finished everything was cleaned up. The house looks great!

Knox's Construction had done some prior work for us (replacing a skylight), so we already knew the quality of their work. Mr. Knox provided us with an estimate that was acceptable. There were several delays, secondary to the unseasonably cold weather, but Mr. Knox maintained regular communication with us to keep us informed of the situation. Once we got a break in the weather, they sent a full 8-man crew on the job. They said that they'd be present at 7AM, and that was precisely when they arrived. They worked hard and had the entire job completed by day's end. Their construction foreman met with us to explain in detail everything that was done and to answer any questions that we had. Mr. Knox called the next day to follow-up, and to (again) ask whether we had any questions. All-in-all, it was a very positive experience. We expected quality, professional service and that's what we received - and at a reasonable price.

Attended the 2019 Pittsburgh Home Show interested in getting estimates for a roof replacement. After talking with Chaz at the show we included Knox's Construction on the list of potential candidates. Chaz provided us a reasonable estimate...was not the lowest but was not the highest. We selected Knox's Construction not only because we thought the price was reasonable but the proposal of material we thought was also the best for the money. Despite a heavy workload Chaz worked with us to fit the replacement in to a window we thought was very accommodating (within 2 weeks instead of 8 weeks). They were also trying to deal with the weather uncertainties, and again Chaz kept us in the loop as to the schedule, all to our satisfaction. Chaz's crew showed up on the agreed upon date on-time and ready to go. All members of the crew were courteous and professional and did excellent work. The replacement was done in one day and the cleanup was very thorough. All the shingles, tar paper, roofing debris was cleaned up to our satisfaction, including discarded roofing nails. We were totally satisfied with the work and the cleanup and would recommend Knox's Construction to anyone looking for this type of work. We also appreciated Chaz following up with us that evening with a phone call to make sure we were totally satisfied.

We had a leak that showed on second floor ceiling. The owner kept the appointment that was mutually convenient for him to examine the roof three stories above ground level to determine where the leak was coming from. He crawled into attic space and also examined the roof from the outside. He determined that the leak was caused by rain coming in where caulking had corroded around bathroom vent pipe. He recaulked the leaking pipe and also caulked a pipe on the roof from a second bathroom. He also repaired a hole and nailed down some loose shingles. He told us in advance that the house call itself would cost $200 in cash but it would be applied to any work that was done. He charged us an additional $100 to complete the repairs.

We were so pleased with Chaz Knox's knowledgeable explanation of services, details and options during the initial discussion that we hired them on the spot. When the work started it took three days. The workers were professional, very courteous and thorough. Mr. Knox stated that all of his workers were professionally well-trained and it showed. We have recommended them and would hire them again without hesitation. It was a pleasure to have hired a company about which we truly have only good things to say.

I cannot say enough good things about Knox's Construction. We reached out to Knox's Construction because our house roof was leaking where an extension had been added to cover our deck. We wanted to have the extension removed and the leaking roof repaired. Chaz came out to look at the work and informed us that he would be able to stop the leaking but keep the roof extension. He also explained to us exactly what had been done wrong on it the first time to cause the leaks and that this would save us a lot of money compared to the demo & repair job we requested. I truly believe that Knox’s Construction could have made these repairs, but due to other smaller issues and personal preferences we decided to go the demo & repair route. From the very start Knox’s Construction had great communication, everything was explained clearly and up front. We were given a cost estimate, but as with any job there was the possibility that if something is uncovered in the demo the price could change. Where Chaz was different, is that he explained exactly what it was that he was concerned might come up and how it would be handled if it did. There was no opened ended “the price may change depending on what happens” that other contractors give. There were no surprises during the entire process because everything was discussed and explained up front. There was a significant amount of rain around the time the work was to be done so we were understandably delayed. However, we were never left wondering, anytime there was a chance of a rain delay or anything else Chaz would contact us, if it was a long delay he would schedule a follow up call where he would call us closer when a judgement could be made. Every time we got off the phone we knew exactly what to expect and had all of our questions answered. Once the weather cooperated enough that the work could begin, it was over almost before it began. I have never seen a crew work so quickly yet never sacrificing quality. The attention to detail the crew showed was astounding including the effort Chaz went through to make sure the replaced shingles matched perfectly. Most contractor’s I’ve worked with in the past would have said black is black and moved on. Chaz worked with us to determine the exact manufacturer and shade, truly demonstrating the quality of the work he does, as well as the pride he takes in his work. When the work was done, and the Knox’s Construction crew left, it looked like no one had even been there. They were extremely conscientious of our property and cleaned up extremely well. We are beyond pleased with the work that was done and will not hesitate to use Knox’s Construction again in the future.

There were unknown problems with the rubber roof part of the job. The obstacles were overcome and the end product was very nice. The crew was very professional and took great care in performing their duties. The property was spotless when they left.

I thought I would need new gutters on the back and side of my house. After inspecting the damaged areas Knox advised that repairs would be the best option and that new gutters were not needed. The repairs were done quickly and I believe I saved a lot of money by working with an honest contractor.

Knox Construction's quote on my roof was not the highest, nor the lowest of my four bids. They arrived when promised, and responded to messages within a few hours. My house is small, but they were in and out in one day. They did an EXCEPTIONAL job cleaning up afterwards. It has been a month, and I have only found 2 nails hidden under a bush next to the house. I would defiantly recommend Knox Construction.

Sometimes a person gets lucky in life and my wife and I feel that way about meeting Chaz Knox of Knox's Construction. There are approximately 62 contractors in the area that do roofing and choosing just one is a "best guess" task for the most part. I met Chaz because he was the only contractor that would come to the house and repair a couple of gutter leaks. The five I called previously all said they only replace roofs and gutters, not repair. Their loss..... Anyway, we had just purchased an 18 year old house and knew the roof would need replaced in the very near future. When Chaz came to repair the gutters I asked him if he would mind looking at a few areas that had caught my eye as possible problem areas. He showed me ripped shingles, shingles that were not properly adhering to the roof, flashing areas that were possible water intrusion threats and the overall deteriorating conditions of all the shingles. He informed me that the roof probably had a year or two left on it, but it would need replaced sooner than later. He did not put on a "hard sell" or make me nervous about the roof, he just told me how it was. I appreciated his candor and as such, I asked him to provide me an estimate. Amazingly enough he was able to give me an almost immediate estimate because he uses a space satellite service that can measure your roof and provide the contractor with all the data required to make an educated estimate. He gave me the $$ number and told me, "This includes 5* rated shingles, new seamless gutters, new fascia, new drip edges and new downspouts....to be honest, he had me at the shingles price because it was less than I had guesstimated...the gutters, etc. were icing on the cake!! Because the price was what I considered very fair we also opted for the gutter protectors. All the above happened in November, 2016 and Chaz told me the work would begin in the spring of 2017. I received a contract, signed it, and waited for spring. Chaz contacted me in January and February to let me know all was still on schedule and then we started coordinating actual install in March. Our roof is a bear due to all the valleys, hips, ridges, gables, 310 feet of gutter, a chimney and two separate, small roofed sections for porches. It took a five man team six days to complete the entire project. The team: One foreman and four guys of varying skills. Five guys that have been well trained in the art of roof installation and how to work well together. Each of them knew their role and responsibility and did not skip a beat. It was impressive to watch them. They were also extremely well mannered and respectful...gotta love that!! In a nutshell, they showed up on time, the foreman told me what would be done on that particular day, they did not dilly-dally around and they did their jobs efficiently and well. At the end of each day they completely cleaned up their mess and ran a large magnet on wheels completely around the house to pick up loose nails from the removal and installation of shingles....let me reiterate "they were very efficient". We purchased Certainteed Pro shingles and because Chaz is a Select Shingle Master and his install team are properly trained we received the highest warranty available (5 Star). Now the important part...the roof looks incredible and the new fascia, gutters and downspouts just pull everything together!! Even the neighbors are commenting and lauding everything. It completely transformed the look of our house....it's a very rich look and adds immensely to the curb appeal of our house. We're loving it!! So....I'm sure there are other reputable contractors out there, but they are not a dime-a-dozen as I learned trying to find one that would repair my gutter leaks. Should you be in the market for a roof I highly recommend Knox's Construction. As the beginning of this review stated "Sometimes a person gets lucky in life...."

Had to reschedule installation due to weather. Knox's construction arrived promptly on rescheduled service day and had half the roof completed the first day. They removed old roof vents; covered holes, cannot even tell there was anything there. Replaced with new ridge vent which looks awesome! The other half of the roof and gutter were finished the second day. The fascia replacement was an after thought once the new gutter and roof were on, the old fascia looked awful. Chaz, the owner, was able to put me on the schedule 2 weeks from that date. I wished it could have been sooner, but that's just me :)  Chaz had 5 guys working their behinds off to get this job done. Chaz's foreman Bud was fantastic, polite and honest. I walked with him on the final inspection before we cut the check and he explained certain aspects of my roof that I would never had known. All clean up was handled appropriately, you can tell this group takes great pride in the job they do; big or small! Fantastic job guys, Thank you!!!!

I called in April (or late March) to get an estimate. Chaz came out the next day or so to do it. We were informed that they were scheduled out until the end of August. We signed the contract and were put on the schedule for the second week of Sept. No money was required as a down payment. The estimate was $9,200 and we chose to upgrade the shingles for an additional $1,100. Chaz also dropped off large samples of the two colors I was deciding between. I was called Tue Sept 15th; we were able to hop one customer who was on vacation if they could come Thursday morning. We were able to do that so the crew came, as scheduled, at 6:30 Thursday & Friday to do the work. They took care with our landscaping & exterior furniture, cleaned up daily and went around with a magnetic sweeper to pick up errant nails. We paid when the job was done. The dumpster was dropped off Thursday morning and taken away Sat morning. It couldn't have gone more smoothly and we're very happy with our new roof.

Knox Construction did an exceptional job.  
(1) The owner met with me in spring and promisted a late August/early-to-mid September date, and he lived up to his word.  He called me at the end of August to tell me when his team would arrive and what to expect.
(2) The owner and crew arrived as promised on September 15.  They introduced themselves to me, told me what to expect with the project and how long it would take to complete.
(3) All crew members were respectfu and professional.
(4) The job was completed perfectly.  The roof looks great.  The gutters and downspouts are a perfect match to the home.  The yard and garage were cleaned to perfection.
I would definitely refer Knox Construction to other homeowners.  I am completely pleased with the overall professionalism, cost, service, and finished product.

Called Chaz Knox back at the end of March to arrange for an estimate for a new roof, based on Angie's List reviews. He had apparently just gotten done with the Pittsburgh Home Show and was pretty booked up for estimates, but was able to squeeze us in. His estimate came in at the highest (albeit not by much), but we went with him due to the positive reviews and the detailed estimate/contract form we were given. Chaz was friendly, but professional, and knew we were moving in a few months and promised to get us in before then. Called them back towards the middle of May to see when we might expect to be scheduled, and was given a date of mid-June. However, due to remarkable good weather here, he called back the week of Memorial Day to see if he could start by the end of the week! Fantastic, except that we were out of town and hadn't made a color selection, etc. Chaz was ever so patient with us while we arranged things, and really went beyond to take care of things while we weren't home. His guys finished up the following week; foreman Buddy and the crew were prompt and considerate, and they took the time to sweep the perimeter of the house to make sure there was no debris. The new roof looks fantastic!

We received an accurate estimate of replacing our roof.  (within $300)  The crew that removed our old roof and installed our new one, were not only highly qualified installers, but they were also neat; cleaning up the area around the house each day, on time; starting at 6:30 a.m., and as well very polite.  This is a well run company.  The owner, Chaz Knox, expects a lot from his crew and they delivered. (Plus - Knox was also on the roof many times assisting his crew)  Granted, replacing a roof is a very expensive item - BUT we know it has been done right and also that this company stands behind their work.  I highly recommend them.

We hired Knox's after talking with Chaz at the 2014 Pgh home show, doing homework on the company, meeting for an estimate and also getting two others from highly-rated area roofing companies.  No deposit was required.  The only apprehension came when I asked Chaz if he could point us to similar jobs in the area / references so we could see what I roof might look like, especially where the shingle product and color we selected were identical.  He said that would take too long to go back and find, and he was too busy to provide that information.  He was not willing to provide photos of similar jobs as an alternative for the same reason, both of which I found disconcerting.  I also learned after the job was set up that the National Roofing Contractors Association doesn't recommend using a vented drip edge in climates like ours due to potential ice damming issues.  Knox's said it was required for the warranty, but since our house has no soffit to ventilate and existing issues with air circulation in the attic anyway, we decided to go ahead with it.
Originally we looked at fall 2014 to replace the roof, but decided to wait until the spring for the job.  I ended up calling the company to inquire when they planned to get us on the calendar right as the weather broke, and by the next week we were on the schedule, only a few days from the call.  They estimated a two-day job and intended to start on a Friday, but weather pushed things back to Saturday.
Two quirks before the job got started.  Knox's contracts with a local waste company to deliver and retrieve a small Dumpster for the job.  This company originally delivered the receptacle to the wrong house, so the morning of the job they moved it to our property.  It didn't impact the job starting, just some time for the crew to clean up when it arrived.  Also, I was unaware that having materials delivered in advance would require a large truck with a crane to hoist materials onto our roof a few days prior to starting to job.  Fortunately I was home when they came, because the truck was so heavy the driver was concerned my concrete driveway might crack just by having the truck drive and park on it for a short time.  Fortunately, no damage was done.
The day of the job, the crew of four arrived half an hour early, and got started right away.  The foreman Buddy thought they would only need a full day, and that's exactly what ended up happening.  I appreciated that they tarped everything and seemed to take care not to create a huge mess as they yanked the old roofing off.  Over the course of the day, the crew did a fantastic job.  Buddy noticed one of our exterior shutters had come down, so he rehung it with better hardware as a nice gesture.  The roof itself is pretty basic in two sections, but the crew worked almost non-stop from their 7:30 arrival until they cleaned up by 5:30 - no screwing around.  We did get lunch for the crew, but I think they only took about 15 minutes for that.  Buddy even noticed that one of our shutters had fallen down and offered to reattach it with some new hardware which he did, free of charge.  The only hiccough was that the crew didn't cover our radon vent pipe that exhausts adjacent to the roof, so when they removed the old shingles, a bunch of particles got trapped down the pipe.  But Buddy stuck around afterwards patiently to help me clean it out and put the piping back together, resolving the problem.  At the end of the day, I had to step away at the end of the day and they were patient waiting for about 20 minutes while I returned to pay for the job.  Sending them home with some "party favors" probably didn't hurt either!
Overall, we were very satisfied with the experience with Knox, especially the look and workmanship of the new roof.  The operation could use a bit more polish, which is why I gave the "B" ratings for responsiveness and professionalism, but at the end of the day the work was outstanding, and the crew performing the work did a great job.
