Roofing & Gutters reviews in Canonsburg, Pennsylvania

Knox has been one of the most honest and reliable companies I’ve ever dealt with. Plus the work is top quality and reasonably priced. If you need roof repairs, don’t hesitate, call Knox

After the tornado, we lost some shingles on our roof. Knox was available with a speedy, accurate and impeccable estimate and repair! The price was super reasonable and the customer service was wonderful. Tom did the repair work and was responsive and so friendly. Chet was also so friendly and warm. They made a stressful situation so much easier to bear. Thank God there are still companies like this!! Would happily call them for any contracting needs!! A+!!

I had both a roof and deck replaced with gutter guards put on at the same time. From start to finish, the experience was fast, professional, and hassle free.
The crew that replaced everything was courteous and very neat. Every day after construction you couldn't tell a crew had been working. All areas were swept and picked up.
I highly recommend Knox's construction to anyone looking to have work done.

Knox construction was an excellent company to deal with. I was kept up to date by their Manager, Casey during the whole time they were there. Very friendly and professional person to deal with. The bill was exactly what they quoted. Would recommend this company.

Knox Construction recently replaced all of the vinyl siding on my house and their work was excellent! Their advice on styles and colors, without a sales pitch, was exactly what we needed to start. They stayed on schedule throughout the project and their craftsmanship was of the highest quality. They even found and fixed a roof leak for us along the way (no additional charge). The crew was professional and polite all the way through and they cleaned up their worksite every day. I couldn't be happier with their work!

Knox did an excellent job helping make repairs after a bad storm. Tom and his team do high quality work, completed quickly, and the were friendly and professional throughout. Highly recommend!

Chaz and his crew at Knox's are great! I called with a very minor repair needed on my house, just to have a vent cover put back in place from a recent storm. I called multiple places and was given outrageous prices and an 18 week lead time. Chaz responded to me within seconds of me reaching out, gave me honest information, and a crew was at my house the following day. I will definitely be keeping Knox's in mind for future projects!

Outstanding company!! The material and the workmanship were outstanding. Very easy to work with. Workmen were very polite and professional. They were very concerned that we were satisfied. I would recommend Knox Construction 100%.

Extremely pleased with new roof by Knox Construction. Chaz is extremely professional - shows up on time and offers absolutely reasonable bids for their work! His crew is extremely professional - they came right on time, did their best to not be disruptive to the neighborhood, and cleaned up everything after they were done (including cigarette butts!).

Also, I can't say how impressive it is they tore down my existing roof (heavy terra cotta tiles!) and replaced it with the new material, including chimney scaffoldings, etc., ALL IN ONE DAY!

Should I ever need a roof replaced again, I'm definitely calling these guys back - and I'll recommend them to everyone who asks!

The photos attached are before (red tile roof) and after (black composite shingles).

I researched a handful of local roofers and found Chaz and his Team to be the best fit for us. They run two crews (all full-time guys, no subcontractors). We had “Bud” as the lead project manager and his 5-person crew for 6 1/2 days. Bigger project. They redid everything for us - new shingles, flashing, soffit (white vinyl), fascia (white aluminum wrap), gutters, leaf guards and downspouts.

Even after being shut down for COVID and losing a big chunk of the summer, I never felt like they were rushing the job. Their quality of work aligns with all of the other reviews you see online. All hard workers and most of them have been working with Chaz for numerous years. Started most days at 6:00-6:30am and put in 10-12 hour days. They did a great job cleaning up each day and spent over an hour walking the property on the final day.

I’d feel comfortable referring him to friends or family or utilizing again in the future. See picture for finished product (color = Landmark Pro Max Def Pewter).

I highly recommend Knox Construction! The very hardworking crew did a superb job replacing the roof and cleaning up thoroughly afterwards. Thank you to salesman Armand, project manager Casey, and the excellent crew from a very satisfied customer!

I placed a call for a roof inspection and repair at 1:30 pm expecting to make an appointment for later in the week. I was shocked when I received a call at 4:00 pm from Tom saying he could be here within a half hour. By 5:00 pm he had found and repaired the leak and took photos of the roof showing clearly the roof's condition. Nice crew doing a great job. I couldn't be happier that I contacted Knox.

Due to the overall condition of the roof, I decided to replace the roof and contracted for the replacement on a Friday. I was told it could be done in 2 to 4 weeks. The following Tuesday I was told they were already prepared. The job started that Thursday and finished that Saturday despite having rain interruptions. The roof, gutters, and downspouts are beautiful, a great improvement. The clean up was thorough and, to my surprise, they made some repairs to my siding as well. Extremely pleased with the project. Once ag again, I couldn't be happier that I contacted Knox Construction.

New roof looks great! 1 day and everything was done and cleaned up. Casey (GM) easy to talk and work with! His crew just showed and worked. Professional and hard workers! No complaints about them. I will recommend Knox’s Construction for roofing work.

A very professional company! Chaz Knox came to our home for an estimate on new vinyl siding. We were extremely pleased with the price and his knowledge. The crew did a fabulous job on the install. Tom was courteous & answered all my questions. He is a well skilled vinyl installer & we're so pleased with the results!! Ryan and Billy are hard working young men. They worked diligently in cold weather & seamlessly as a team. We are so happy we went with Knox Construction & highly recommend.

Chas Knox and his team have earned a 5 star rating from my wife and I. They checked all the boxes and more for us. Every man on their team, and I mean there were 10 of them here, were very polite and courteous and they worked hard and steady like a well oiled machine. 33 square on the house roof and 12 on the garage and they ripped off the old shingles and had the new installed with ridge vents in 6 hours flat, and that included a half hour lunch, we’re we got to mingle with the crew, and total cleanup!
Highly recommend these guys! Thank you Chas, Joe , Ura and all you other guys!!!

Knox Construction came highly recommended to me by a friend who had a vinyl siding installation done by them. I was not disappointed. From my initial phone inquiry to a friendly and courteous Tina Knox and several equally great follow-up conversations with owner, Chaz Knox, I was convinced that repairs to my wind-damaged back porch would be handled very professionally and successfully. Tom Murray was very easygoing and polite while coordinating the on-site repair work. Tom was also very thorough in clearly explaining the necessary repairs and he, Billy, and Ryan did a super job in a very timely fashion. They even cleaned the porch gutter without charging a fee. I was very impressed and pleased with Knox Construction and plan to contact them for another home improvement project later this year.

The crew from Knoxs was professional and on time. They communicated clearly and answered any questions I had during the process. They cleaned up during and after the roof replacement and explained the details of their warranty throughly. I’d highly recommend their team for any roofing needs.

Chaz was professional fair price too completed our garage that another contractor screwed us by taking money and not completing job . I’ve referred Chaz everyone loves his work. If looking for honesty in a contractor CALL CHAZ

Chaz Knox and his crew did a great job. His crew was fast, efficient and well coordinated. I spoke with several of his crew and all were polite, easy to converse with and attentive.
The clean up was first rate. They did not damage any landscaping or plants. I could not find any debrie left behind.
I misunderstood one aspect of the quoted work and when I discussed it with Chaz, he offered a very amicable solution. I even made a mistake on information I provided to Chaz regarding the gutters. Chaz again offered a solution like a true Gentleman. I was well pleased with our interactions.
I offer the highest recomendation to anone considering Chaz and his crew.

True professionals! Chaz, Buddy, and their crew understand their roles in their company and are each masters at their craft. The team from Knox's Construction do the highest quality work I've seen and offer a warranty to back it up. In replacing our roof and adding gutter covers (and some water-damaged boards underneath), they showed a unique combination of efficiency (2.5 days start to finish), carefulness (we found not one nail left in the ground after they finished), and kindness to my family and to one another. It is refreshing to see a team enjoy their hard work. Chaz was also a man of his word, and someone I won't hesitate to trust with any of my future projects. Well done men!

I had a great experience with knox construction for my new roof. Chaz met with me answered all my questions and followed up negotiating a good deal for a quality service. Casey was excellent at communicating the project from start to finish including an unfortunate rain delay. The crew completing the work was kind, courteous and did a great job cleaning up and completing the work In the time frame provided. My estimate was spot on no unexpected surprises. I would be happy to recommend them and use their services in the future
