Cornell Roofing came highly recommended by people I know and trust. So, it was no surprise that from the beginning, I was very impressed by them. Starting with amazing communication and follow through (which I find is rare these days) and excellent work on replacing my roof. The team of workers were thoughtful and thorough. The price for the roof was also fair. All and all, they really went over the top for me and I highly recommend Cornell Roofing. read more

We had our 27 year old roof replaced by Cornell. A complete tear off and install. They were professional at every level. The crew was incredible to watch: Tear off, daily cleanup, handling of materials from truck to roof, installation of sheeting and shingles. They were so synchronized - amazing. Management of the project was spot on. I'm recommending Cornell to anyone who needs roofing done. read more

Cornell roofing recently re-roofed the flat roof portion of our small bungalow home in Albany. Everything about this experience was excellent. Their comunication was timely and responsive. Their planning gave us a well calculated expectation of when the job would occur and how long it would last. The workers were careful to protect our property during a job that is necessarily messy with hot tar. And the workmanship was careful and attentive - excellent! Clean-up was amazing. We were surprised and appreciative that they pressure washed the entire work area before leaving! We questioned a couple of areas we thought might need to be caulked along the parapet wall and they returned right away to make their job perfect! We recommend them with our highest praise! read more

Great communication. Responsive. Market price. Quality work. Would recommend (and have) and use again.

I am a widow so I thought finding a reliable roof/gutter company would be daunting! It was not once I spoke with Cristen at Cornell Roofing in Concord. Kristen set up an appointment with the owner, Clint, for the next day. Clint looked at my home roof and detached garages roof thoroughly explaining the work that needed to be done. He was easy to talk with and I had a good feeling about him and his company. I received an estimate that evening.and signed a contract within a couple of days.The installation crew started the project within three weeks. This crew was courteous, friendly,EXTREMELY hard working, and didn't leave any debris after completion of the instal. Not even a nail! There was some roof damage due to condensation in the attic and that repair was discussed with me and Clint before it was thoroughly repaired. The gutter crew was also taken care of by Clint and, again, hardworking people who were unbelievably precise in all of their measurements. This is a third generation company that treats its employees like family, as well as, people like me! I have already had two compliments by people walking past my house!! read more

We were so thankful to find Cornell Roofing to replace our roof and install insulation over a large room with cathedral ceilings! They were so patient, flexible, and trustworthy. Also, easily approachable and made sure all our questions and concerns were answered. They made sure to clean up afterwards and showed up on time. We would highly recommend them!! read more

When our 1990s-era shingles were looking threadbare, Ron from Cornell inspected and told us to replace in 2-3 more years - rather than try for an immediate sale. We appreciated Ron's explanation of their replacement criteria and his honest approach. We bookmarked them. When we were ready, Clint came and proposed a plan for the roof, gutters, skylights, and attic venting. His ideas were prudent, his detail was clear, and Cornell's pricing was competitive. Cristin @ headquarters responded promptly to our many emails. In only five days, the Cornell team: + Refreshed the curb presentation of our home by installing fresh, new, shingles that make our roof surfaces and angles look crisp, neat, and clean. + Updated our appearance by replacing flat sided gutters with new ones showing a subtle streamline indentation which added modern visual appeal. + Replaced angled downspouts with curved spouts. Much easier to flush out leaves. + Brightened our interior with new skylight domes in place of our 1970s yellowing skylights. Very reasonably priced. + Simplified our attic exhaust system by upgrading an old problematic wired fan with a wireless solar powered model we can't hear and don't fuss with. + Quality-controlled for any remaining details by Clint Jr and Rubin who addressed a few questions we had at the end of the project. They made sure we were completely satisfied at closure. The whole Cornell team is very trustworthy. Excellent quality. Fairly priced. Respectful of clients and existing property. The new roof gets many compliments from neighbors and people passing by walking their dogs. Photos posted here. read more

We have a flat roof and have used Cornell for over 20 years. This company is so knowledgeable, helpful and, most importantly, HONEST. Highly recommend. read more

From first contact with the office, to job done, Cornell is awesome. We have an unusual shaped roof with a history of leak issues on our main house that was ready after 25 years for shingle replacement and two structures that needed T & G. Clint and Ronnie and team addressed the old leak source, and designed and installed new custom gutters on the main roof, took care of some dry rot, and addressed the flat top roofs. This was a challenging job and the crew followed up with every detail. The price was very fair. Thank you! You're the Best! read more

I just wanted to give a huge shout out to Cornell Roofing. I was under pressure from my homeowners insurance about my older roof (it was confirmed by multiple contractors it still had a few more years life to it, but home insurance pushed back hard - "loss of granulation" - I think I pulled a muscle with that eye roll). After getting bids from a number of roofing companies, Cornell got my vote hands down and they did NOT disappoint. So glad I went with them. These were the things that impressed me from start to finish: 1) really appreciated Cristin in their front office; she was on it from start to finish with paperwork, scheduling and coordination; 2) meeting Clint Jr. and discussing options and details; he was able to come out pretty quickly, assessed the roof, detailed my roofing options with no hard sales tactics, just straight up options, cost-point, etc. For the couple of things I wanted to add, he said they weren't necessary but he'd add them to the bid if I wanted them, while reiterating I could keep the cost down if I chose not to include some extras. How refreshing as compared to other contractors who pressure with unnecessary extras. He just straight up gave me his opinion and offered a very fair price; 3) having the roofing crew on site; led by Joshua, they worked hard and had my old roof off in under 2 hours and were well on their way to finishing the installation of the new roof at the end of day 1, and finished on day 2; they were solid and I was extra appreciative of their attention to detail and care. They were careful with the demolition and cleaning up. There was no debris scattered about at all. I have some windows that are lower, and they took care to protect those with plywood. As scheduling availability would have it, I had just gotten my house painted right before the roof went on and I was a little nervous. Didn't need to be, their demolition and cleanup meant nothing hit the house or marred the new paint job (again, wouldn't have chosen to do it in that order, but had to coordinate contractors' availability); 4) really appreciated the heads up on permit requirements; Clint Jr. gave me a heads up that I'd be required to install a gas earthquake valve as part of my roofing permit sign-off. Being told that ahead of time gave me the time to schedule a plumber and have that installed over a week before the roof was even installed, which meant it was there and ready for the inspector when he came by to sign off on the permit. So grateful to know that with time to get it squared away vs. trying to schedule it in the 11th hour. I've gotten multiple compliments from neighbors (I chose to go with a longer-lasting architectural-style asphalt shingle.) Overall, Cornell Roofing did a great job and I would recommend them to anyone needing a new roof. Thanks Cornell! read more

26 years fter Cornell Roofing put on my roof, I incurred a leak, caused by damage from the rooftop pool solar system. After gettibg a few exorbitantly high repair estimates, I contacted Cornell. Two men came out the next day and successfully fixed the leak. Thanks again, Cornell. read more

Quick shout out to Clint...he came out to check on a roof leak from the Spring and quickly identified the problem. Turns out it was a relatively small issue that was easily fixable. Clint told me exactly what to do and even provided a small part. I appreciated his honest approach (as opposed to charging me an arm and a leg) and in the future he's my first contact if I have any roof issues. Refreshing to know pros like Clint still exist. read more

Our home needed to have an older cedar shake roof replaced. We wanted the replacement to be durable and more fire-resistant. Based on a recommendation of a family member who recently had their roof replaced, we contacted Cornell Roofing Company. Clint Sr provided a roof inspection, recommended what we needed for re-roofing, and provided a proposal that was thorough and reasonable. We proceeded with Cornell and are glad we did. The old roof was removed, and a complete new roof installed over a period of 5 days. The Cornell team did exactly what they committed to do with no surprises. Their crews arrived on time each day, were professional and efficient, and they cleaned up and removed any construction debris. Cristin in the Cornell office was always available and responsive for schedule coordination and any questions. We're delighted with our new roof! I highly recommend the Cornell team and will definitely reach out to them for any future roofing needs. read more

Clint, Clint Jr and team did my roof and my mom's. They gave dates off when the roofs would be started and finshed and they met them. They are very professional and make sure they cleanup. I highly recommend them. My chimney needed some repairs and they did an excellent job. read more

Another satisfied customer of Cornell Roofing. I needed some tar and gravel flat roof sections on my house re-roofed. Clint promptly came out and gave a reasonable bid. Because my roof is quite visible from the street, he understood my need for aesthetics and had his workers also paint the new vents, flashing, and the conspicuous side of the gutters. His workers worked efficiently and cleaned up nicely after the job was done. Cornell Roofing is a four generations family-owned business. I feel confident that if I have a leak or roof issue, I'll know I can count on Cornell Roofing. read more

I can't recommend Clint at Cornell Roofing enough. He was recommended to me by my brother after he did his roof a few years back, and they did an awesome job on his roof. I needed some patch work done on my roof and he responded immediately and even though it was the rainy season he was able to come by within two days of me calling. He was at my house on time and the job done quickly, courteously and most importantly the job was done well. We stopped and talked for a while afterward and he mentioned this has been his families business for about 64 years, and you can tell he's passionate and knowledgeable about his work. Great service. read more

Cornell Roofing was recommended to me by my real estate agent as I was preparing to purchase a new home. They did a roof inspection free of charge, and were honest enough to share that while my chimney flashing needed repair and my gutters/downspouts needed to be replaced, that I had 4-5 years left with the existing roof. Clint provided me with a very fair estimate to repair the flashing and replace the gutters and downspouts, and I decided to move forward with him. This time of year as a roofer Cornell is very busy, but Clint called me before an impending rain storm to say he would be over the next day to repair the flashing, before the rain hit. A man of his word, Cornell Roofing showed up and got the flashing repaired - and replaced the gutters/downspouts shortly thereafter. Everything works and looks great! read more

Cornell Roofing are experts at their craft. Family owned, reliable and detailed oriented. Clint, Clint Jr. and the entire team are experts, and are completely transparent.

As you and we know, this is a large investment in your home, we give a 5 star rating and recommend you too can trust Cornell Roofing. Say yes! read more

The repair was perfect!!! The repair was for the back half of my roof. I came home earlier from work expecting to see the roofer, no one here, was upset! Called and left a message about what's up. Went to my backyard and they had already finished!!!!!! Crazy me, called back to apologize! So, very fast, did what we talked about and that back half looks BETTER than the rest of the roof!!! read more

The entire Cornell Roofing team was great! They replaced our entire roof and gutter system. Clint was fantastic to work with. Easy and reliable. I highly recommend this roofing company. read more

I needed a new tar and gravel roof. I have an open beam ceiling and insulation sheet on top of roof. After several estimates no one seem to know how to approach the job. Then I met Clint from Cornell Roofing. He knew exactly what needed to be done. The workman were here on time. Did a great job. You could tell it wasn't their first rodeo. It's very refreshing to work with family owned and operated business. You need a new roof? Cornell Roofing is the place to go. Period read more

We've used Clint and company for two roofs over the last 2 years (old and new house). Really top notch work! For our latest roof, they repaired a ventilation issue in our vaulted ceilings, replaced most of the shingles (since addon had newer shingles already) and added ridge vents all over. We also let them know that we were going to have solar installed and they made sure to me that there shouldn't be any issues. Solar install went fine (done by Tesla). We highly recommend them to anyone looking for a company that just gets the job done with very reasonable prices. Will of course go back to them for anything else that we need! read more

Great family business! The quality of their work is excellent. They replaced 2 levels of tar & gravel roof on our home efficiently, with skill and attention to detail. All of the employees were pleasant and considerate. They arrived without delays and left the job site neat & tidy -- very much appreciated. We had been previous clients of Cornell Roofing and over the last several years, they had been quick to attend to any repairs needed, important during the busy Covid years. We recommend Cornell Roofing highly. read more

On time, on budget, no surprises, great crew, and the roof doesn't leak.

We had a leaking ceiling during a recent wind and rainstorm. Cornell Roofing sent a couple of guys out to do some patch work. But that didn't solve the problem, so they came back out again and covered our rooftop ac unit. That stopped the leak, but a vent in the ac unit burnt a hole in the tarp, so they sent out a third team to recover the ac unit. That fixed it for now. They went above and beyond in helping us stop the leak. Now for the insurance, and the adjuster, that's already starting out to be a headache. read more

Cornell Roofing did a wonderful job replacing my roof. The workers were on time each day, cleaned up, and there were no "hidden" charges. I highly recommend them. read more

So far so good!! Many of the companies I contacted were busy after this big storm. They were able to fit us in day-of, and make quick work out of stopping the leak. They were prompt and knowledgeable, and discussed how this emergency repair is slightly different than a full repair. I'm just happy it was quick and stopped the leak. I'm going to keep them in mind for additional roof maintenance, and full repairs if necessary. read more

This follows my previous email. Really great service is when a contractor comes out after he's already been paid. That's what Clint did for us; he identified and fixed a problem for which he wasn't even responsible. You can't get better service than that. read more

This operation is TOP NOTCH!!! I called them for some simple roof repair that needed to get done during the rain season. They were extremely helpful and accommodating... they completely understood our predicament with the eminent rain and made adjustments to make our repairs a reality before the heavy rain. The prices are reasonable, the customer service is AWESOME, and I'm happy to spread the word for all folks looking for roof work and honors customer service. Thank you Cornell!!! read more

I want to express my appreciation for the tremendous service provided by Cornell roofing and Ron McHenry in particular. Ron provided a clear detailed proposal for the replacement of my flat roof. He worked with me to devise a plan for the gutter and downspouts to redirect the water The work was performed timely and the crew was friendly and efficient read more

Really pleased with the customer service and excellent work. I have had recently replaced a roof with Cornell Roofing, and also cleaned our gutters. I was pleased with the results and the price was totally fair. read more

I contacted this company to come out and inspect for a roof leak. The woman that answered the phone was nice and said she would get Ronnie to come out and inspect. He came to the house as promised, walked around the roof, went into the attic, walked around again and said he could not locate a problem and left. I got a second opinion from another roofer who found the problem immediately and gave me an estimate in advance. I think this guy just wanted to go home and didn't want to thoroughly inspect my house, because if he did, he would have found the issue. He claimed to be in the business for over 20 years and he was nice, BUT he did not locate the problem which ended up being super simple. Be mindful before calling these people, they seem ok but Ronnie did not put in effort to fix my roof. read more

We had a skylight leak on a really rainy day. Clint fit us in on a busy day. No more leaks! I now have Cornell in my speed dial!
