Times have changed since my last roof, It’s a whole new roofing process now- a- days !I have a simple cape cod with 2 “dog house” type dormers. which gave me issues on my last roof 25 years ago.Marvin assured me i’d have no dormer issues with his roof.The company’s website showed past jobs with my type of dormers. Great peace of mind !The crew showed up on time and ready to go. Pure team work and very detailed and talented ( and safe)I received a VERY fair price. I chose the Owen’s Corning shingles and Marvin, at my request helped me pick the right color based on the house and neighborhood to blend in perfectly .The job was done in 1 day ( house and 2 car garage ) and Gutters installed the following morning .I waited 3 months to write this review.

August 29 · FrankAlexander Home Improvement did an excellent job on my roof. The company was very professional. They were very good about protecting everything around the house, making sure not to damage or break anything. Any items that were moved were put back exactly how it was. They made sure to clean up everything, not even leaving a nail on the ground. All of the workers were respectful, courteous, and friendly. I highly recommend this company if you are looking to do your roof and the price was reasonable and affordable. Would I use them again? Yes, I would, and I'm considering having the same company redo my siding on the house.
June 27 · shrille whiteAlexander Roofing was awesome to work with! Not only did they give me the best price, but they also really stand by their work. They’re an Owens Corning Platinum Preferred contractor (I even double-checked on the Owens Corning website), which gave me extra peace of mind when choosing them.The whole team was super friendly, and the job was done in just one day without having to reschedule. They even registered my shingles with Owens Corning, and I got the email confirmation right after the work was finished. I did notice a small blemish afterward, but when I let them know, they immediately sent someone out to fix it—no chasing or runaround at all.I chose the Heather Grey Duration shingle.Honestly, it's rare to find a company this professional & easy to work with. Highly recommend Alexander Roofing if you want quality, value, and peace of mind all in one. All in all, great service, great value, and a company that actually delivers on their promises. Highly recommend!
August 16 · jimmy aAlexander Home Improvement is the best company out there to get your job done. Alex and his whole crew were amazing from start to finish. This company goes above and beyond your expectations. Their attention to detail will blow your mind. From the itemized estimate, to the way the crew showed up on time each day, to how much attention they paid to keeping the site clean after every phase of the project, and making sure you are happy every step of the way, this company is number 1. Arnold in the office was on point in getting everything coordinated to keep the job moving. Thanks to Santiago and his crew, and Freddie and Antonio as well. Alex's honesty and transparency are second to none. He and his company delivered everything promised and then some. All of this, plus a fair price and getting the job done quickly without rushing it makes Alexander Home Improvement the company to choose for your next project. I cannot say enough good things about this company. We would give them more stars if we could. Thanks again to Alex and the whole crew. We love the job you did.Scott and JoAnn Eagle.Update to come when landscaping is completed.
August 16 · Scott EagleMarvin and team did an outstanding job on our complete exterior overhaul, they replaced the roof, windows and siding for the entire house. They included a custom soffit around the entire house, pictured below. The constant communication from start to finish helped ensure everything moved smoothly. The worked incredibly fast, cleaning well along the way. The team was very professional and exceeded expectations. So many compliments from neighbors already on the workmanship and how quickly they got the work completed. Marvin lived up to his promise to do the job the right way! We couldn’t be happier with the result. (Before and after photos below).
