I’m so happy and please with the way our home has come out. Marvin, Greg and team have fulfilled all that we asked for and more. From the moment Greg the salesman came to our house we felt very comforted going with Alexander. They were wonderful to work with. They completed our roof, siding, stone work, azek trim, lighting and foundation repair. They are very responsive; worked with us to stay within our price range while also not skipping any corners that we were looking for. All of their employees are hard working, on time, stay late to get the job done. They were amazing to work with and highly recommend them!! Thank you again for the beautiful job you all did!

Great company ! I’m lucky to have hired them.
Marvin was amazing! He explained the whole strip and install process to me ! 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. We had some extremely heavy rain storms this Summer of 2025.
I had zero issues !
The Clean up was suburb ! Not even one loose nail found.
I hope you give Alexander Contracting a chance.

Arrived on time with a large crew and then set quickly to work. Roof was ripped in 3 hours. Then they split into groups and started replacing 10 sheets of plywood and placing ice shield and underlayment. Removed an old attic power vent and went to work on shingles for the roof, garage, and bay windows. They placed ice shield anywhere the shingles would touch siding or the chimney. Finally they flashed around the chimney. Finally they spent 45 minutes cleaning up nails and the last debris. I have done roofs after I retired and thought that my crew did a great job, but this crew tore through 14.5 squares in one day. My neighbors couldn’t believe how fast and how beautiful the job turned out. However with all that effort, I still had to have a nail removed from my tire. Beware and triple check.

I recently had a full roof replacement after receiving a notice from my insurance company that it needed to be replaced. From start to finish, I had a great experience with Alexander Home Improvements.
Greg came out and explained everything in detail, answering all of my questions and making me feel confident about the entire process from day one. The work was completed quickly and the finished roof looks beautiful.
Communication throughout the project was excellent—always efficient, clear, and professional. Working with both Arnold and Greg made the whole experience smooth and stress-free.
I highly recommend Arnold and the team at Alexander Home Improvements for any roofing needs.

Alexander Home just completed a project for us and we are thrilled with them and with the results! We found their pricing to be very reasonable, and their work was excellent. Greg was the first person that we met associated with the company and he was excellent - explained our options for new siding and gutters in great detail and answered all of our questions. He was great with communication and a pleasure to work with! The crew that worked on our house was wonderful - they arrived first thing in the morning every day! Marvin was also excellent, and was very involved, stopping by the house several times and was very responsive to any of our questions during the project. Our house looks beautiful after their work, and we were so pleased with our experience!
