EXCELLENT Based on 44 reviews Samantha MacConnoran2025-04-27Trustindex verifies that the original source of the review is Google. Everyone I dealt with at this company was quick to reply, professional and efficient. I reached out them one evening due to a leak in my roof. They coordinated with me immediately and made an appointment for a free quote the following morning. By the following evening, my roof was repaired. They spoke with us in morning to go over the issue and give us a quote and were able to return that same afternoon to complete the work. I'm very glad I went with this company and will keep their information for future services. Quincy Parchment2025-04-17Trustindex verifies that the original source of the review is Google. Does great work, great communication and Definitely works with your budget, They did my roof earlier this year in January and finished the entire roof in under 8 hours with new skylight, and hatch installed 5 stars is not enough truly recommend Kevin Flynn2025-03-12Trustindex verifies that the original source of the review is Google. Looking for a roofer? Looking for a fair price and quality work? Aren't we all? Mark & his brother did a great job by me! AND they anwer their phones every time. I felt that they were very upfront, and HONEST. Can't ask for much more. Would use them again. 👍 Bronxthirdfl2025-02-05Trustindex verifies that the original source of the review is Google. The team from Alter Phase roofing did a superb job on my roofing project. During the initial assessment, they actually took the time to walk my roof and identify all my trouble spots and provided reasonable repair options for me to consider. Other contractors that I vetted, would either send up a drone or use a Google maps view to evaluate the roof condition. I prefer the hands on approach when it comes to inspection, which Alter phase roofing did from the get go. Project price and time line were clearly communicated every step of the way. Demolition to installation and post work clean up was handled with care and professionalism. I highly recommend Alter phase roofing. paul pulakos2025-01-11Trustindex verifies that the original source of the review is Google. I’m usually working so with schedule can’t always be at house.

They did a great job. Owners were very involved in making sure that everything was up to standard and explained everything in detail, they were professional and punctual and very fair priced for what we needed. Would definitely recommend Richard Elrauch2024-10-24Trustindex verifies that the original source of the review is Google. My garage roof is beautiful. I watched as Mike and crew worked, observed the great care they took in addressing every detail. I have never seen work performed with a more conscientious and professional regard. They were absolutely fastidious in the cleanup process. They even offered to make small cement repairs that they noticed around the perimeter of my house and never asked for additional payment. Five stars aren't nearly enough to indicate the superlative work that this company provided. Janice Chen2024-10-09Trustindex verifies that the original source of the review is Google.
