Gen-Ex recently replaced my roof, including some structural repairs. I was delighted, and relieved, that my experience with them was fantastic and easy throughout the entire process. Their communication was great, attention was paid to details, and the workmanship was excellent. This is the third roof I have put on my house - by far the best experience!

Excellent roofing company. Paul came immediately and made our emergency his emergency. He came out again to meet with the insurance and adjuster and quickly sent his team back to make a requested adjustment after the install. He never made us wait. Responsive and conscientious. Very competitively priced, too.Services: Skylight repair, Attic venting repairs, Roof inspection, Roof repair, Roof installation, Attic venting installation, Roof damage repair

So few companies deserve 5 star reviews these days. I am so happy to say General Exterior does deserve it! 2 of their guys came out with smiles on their faces. SMILES! They checked out our roof and got into our attic to find exactly what the issue was as it wasn't clear cut where the water was coming thru our ceiling. They took pics, showed us and called the owner who in turn called us and discussed all our options on what they thought it was. We loved that they were willing to do a small job which is what we ended up needing. Their thorough workmanship paid off 2 days later when it absolutely poured and the roof didn't leak againThank you General Exteriors!! And keep those great roofers you have!

In and out in 1 day as promised! Minimal stress on the dogs with having the work done in such a short time!Realtor got a quote from them for the purchase of our home. Not only did they stand by their word to maintain the price (quote provide in Dec, Job done in April) but they also provided us a 5% military discount!Both owners Paul and David and the office manager Susan are so very pleasant and made this whole process easier than we ever thought possible.So incredibly happy with our new roof! House looks great!

Paul and his crew are true professionals. Received quote that was 25% less than his competitors and was very open with scheduling around weather. Found a perfect shingle match for a 10 year old shingle. New ice/water shield, ice board and step flashing. Would recommend to everyone. Already recommended to my neighbors and he saved them 30k by salvaging their roof, rather than needing to replace.10/10 experience and craftsmanship

Yesterday, Gen Ex responded very quickly and cleared a backup of snow and ice that was causing a leak. About two years ago, Gen Ex installed my roof. It was a large project, and it was mostly completed in one day. The team was very professional and careful to protect my property and clean up after the work was done. I hired them because I felt comfortable with the directness, professionalism and skill of the company representative, Paul Antonou. I was very happy with the results. My neighbor also hired them based on my results.

I placed a call in for some minor repairs on my siding. They showed up and did the job. They were honest with their price point and go on and off the job quickly. I will certainly use them again! It’s nice to work with people who know what they are doing.

Dan and Dave were great people to work with. Everything Dan told me at signing of contact held true. when it came time for installation both Dan and Dave were her to make sure everything was going to Scheule. Dave stayed with the crew all day and help set the skylights in their correct position. i am very satisfied with workman ship and performance of the company.

They came out and quoted my small job with no hassle. They repaired the roof where the chimney was removed, plus replaced a damaged vent. The price was right and they were able to fix both issues same day. They also did a nice job of cleaning up afterwards.

We had storm damage to our roof and gutters. Paul and his team addressed our problem and worked with our insurance. Our roof was completed in less than 8 hours. The gutters were shorter time than that. I cannot thank Paul and his team enough, for being the most professional contractors around. If you need a great contractor call Gen Ex.Thank you Paul and team !!!Service: Roof repair for storm & wind damage

This company was amazing to work with. Very responsive and a good value. I had them install new siding for my garage and they did a phenomenal job. It’s been about a couple weeks ago and it has stood against severe thunderstorms and tornado warning winds. Very pleased with their work and I will definitely consider them for future projects. Highly recommended.Services: Installation, General repairs

GenEx installed a new Cedar roof on my home in Cary. I couldn't be happier with my choice. From the initial phone call to every follow up conversation to the care they put into their work, they have been beyond professional. I spent a lot of time over the last few years getting repairs on my old roof, researching contractors, getting quotes for new roofs and, ultimately, found Paul via a friend's recommendation. Paul was, by far, the most professional and thoughtful contractor to look at my roof. He clearly was not just trying to sell me a roof. He spent a great deal of time up on a ladder inspecting the roof (surprisingly, most contractors never even looked at the roof up close, but instead just quoted using satellite photos). Paul was genuinely inspecting to see if I could get away with another year of repairs. Throughout the entire process, he consulted and advised including trying to make sure I was comfortable going the more expensive route (cedar). In the end, I decided to stick with cedar and do an entire new roof. The price was very fair compared with other contractors (especially given the rising price of cedar and current economic/supply chain issues in 2022). They began work right away. The crew led by Thomas was fantastic. They took great care to protect the exterior of my home including putting up giant protective nets and structures as they did the teardown. The work was great. They worked the weekend to get the work done. The cleanup was thorough and, in the end, I would highly recommend GenEx for any roofing job whether going cedar or not.Services: Home renovations, Roof inspection, Roof repair, Roof installation

Gen Ex recently did a roof on both our home & on our garage all in 1 day! I have to say that we absolutely love it! We have recommended them to quite a few people so far. They did a fantastic job.Doug was so nice & we loved how he did the quote professionally but without any pressure. He gave my husband all of the facts & took him through it step by step. Our roofs have never looked better. Thank you so very much!Services: Gutter installation, Roof installation

Called Gen Ex to come out and quote a full fascia and soffit repair and replacement. Had rotted wood in some spots. We went with the maintenance free option that the aluminum soffit and fascia brings. The house looks beautiful. Paul was great from our initial meeting (quote) throughout the project. They met our timeline and completed the job, along with some additional repairs to our siding that we needed, within the 2 days, as stated. Have recommended them to a few neighbors looking to do the same. Cosmo and his team were great to work with and took the time to answer all my questions.

Great work at a fair price. Explained job well, did what was required and didn't oversell.Had woodpecker damage on a chimney bump out and they did a great job matching original siding from the 70's, as well as the existing paint color. Would definitely recommend.

We recently had our roof replaced by Gen-Ex and they were awesome to work with throughout the entire process keeping us informed ahead of time as to what to expect and always willing to answer my questions. Their price was competitive with my other estimates. I felt their crew was outstanding! They came in and got set up, taking great care of our landscaping and bird feeders etc. using a mesh tarp that protected everything from the debris, but allowed the air to flow through it. Everyone knew their role as they got to work removing the old shingles, repairing areas as needed and installing the new roof and roof ridge vents. By late afternoon they were done and their cleanup was impressive with virtually no signs left that any work had been done here. I have already recommended them without hesitation to my family and friends.

From initial inquiry a responsive and professional contact was assigned to my roofing project. The business model was solid with knowledgeable experienced staff that listened and offered recommendations and insight into the process. Quote was competitive and target schedule was met. Crew was very motivated and worked very well as a team. Early starts and long days. One of the owners was on site daily to supervise and troubleshoot any issues. Project was completed on schedule. Very satisfied at this point.Services: Gutter installation, Roof installation, Attic venting installation

Replacing a roof is an expensive endeavor that I feel warrants a detailed review for potential future customers. I used Gen Ex to replace the roof and install gutter guards at an investment property I own in Antioch. Gen Ex was recommended to me by a handyman who had used them previously.I received quotes from several different companies and Gen Ex came in with the best pricing. I'm no roofing expert but to my untrained eye, the roof and guards looks great, no more leaks reported from tenants, and there's no longer a soft spot on the roof!A couple other random positives:Worksite was very clean after they left, no signs that they were ever on the property.During roof removal, a shingle fell and tore a hole in a small pop-up tent that a tenant had up in the back. Gen Ex proactively contacted the tenant and took care of the tent for them.All tenants reported that the crew was very friendly and professional (even the ones with the damaged tent were very positive)I had a downspout that had come loose from its bracket. Gen Ex noticed and secured this again for me on their own.If I had to provide one piece of constructive criticism, it would be that communication was a little bit sparse at times. There were weather delays and a short delay on installing the gutter guards. I received some updates, but wasn't fully aware of timelines. TO BE FAIR: This is an investment property 45 minutes away from where I live. If this was my home, I would have been more aware just by being there everyday. Also, I was not reaching out regularly for updates and whenever I did reach out, Gen Ex was quick to return my call or text with an update. If I had reached out more frequently, I'm sure this wouldn't have even been a thing worth mentioning. I can attribute this criticism to myself as much as I can them.I would 100% recommend Gen Ex to anyone in the area looking for roof repair or replacement. They are true professionals and I plan to use them again in the future for any further needs on my various properties.

This company is one of the best companies I've ever dealt with. A tree fell on my house and damaged my roof. I called them and within no time they were there to help. Greg was absolutely amazing. He guided me through the whole process. He was very knowledgeable and very patient with me as I had a lot of questions. The day they came to replace the roof they had a huge team show up and the roof was done very quickly. The owner of the company came to introduce himself and thanked me for choosing them. They even sent me a thank you package a few days later which I thought was really nice. Again, Greg was absolutley wonderful and I cant thank him enough for everything.

This was the best experience we have had with any contractor of any kind. They worked with my insurance company to ensure all items that should be covered were estimated properly. They scheduled quickly, got the work done quickly and charged a reasonable amount. I work for an insurance company, and I have seen some companies do some shady things to increase the cost of the job. Gen Ex is not that type of contractor. They do an honest job, and they do it professionally and quickly. Could not be happier with this company.Services: Roof inspection, Roof installation

Just had them replace siding and gutters from storm damage based on a friend's referral. Jeff from Gen-Ex went above and beyond to help us choose the materials and deal with the insurance company. Siding job was done in 3 days, gutters in 1 day and our house looks amazing. Highly recommend them!

We had our roof replaced last month after storm damage. I could not have been happier with the outcome. Our roof looks beautiful but what I was happiest about was the customer service. The owner was at our home first thing in the early morning to set up for his crew. He was so hands on that I couldn't believe he was the owner of the company. He covered all areas of our yard with tarps and was mindful of our plants. Most of all he looked after our baby farm animals who were underneath the areas being worked on. He was constantly checking for nails and making sure I was happy. The yard and driveway were spotless when they were done. He even came by the next day to double check everything and he somehow spotted two nails himself in our yard. He immediately called a few of his workers to come back and magnetize our entire property for the safety of our kids and animals. My mom recently got her roof done by a different company in our area and she has had nothing but trouble. I am so thankful we had a great experience with a reputable company and I will be recommending GenEx very highly to friends and neighbors.Services: Roof repair for storm & wind damage, Roof repair, Roof installation, Attic venting installation

Brad & crew were phenomenal! Late season last November, uphill challenges all the way from insurance “persuasion” efforts and unfriendly weather conditions, not to mention the fire that destroyed a truck and still, the job was accomplished with unmatched professionalism! From the day I first watched these guys replace my neighbor’s roof until now, I can say I’ve never seen such an impressive team. In one sense, they actually saved mine and my family’s life when they discovered that a heating and air contractor who replaced my furnace the year before failed to inspect the vent and that all the carbon monoxide was not making it out the roof. You guys are a blessing!Thank you!

The team has been very prompt very kind and very helpful! We couldn't have asked for any better services. They got us everything that our home needed repaired from the hail damage on our roof and gutters.. Gregg is who we worked with the most and let me tell you he is the best. Getting back to us right away, made us understand everything very clearly. Upfront and very honest. Followed up on everything as well. This company goes beyond to make sure you are getting what you are needing.Thank you for all you have done for our family!Services: Window installation, Roof installation, Roof damage repair
