Amazing service. Mark responded within minutes of sending a message on Yelp. It was a weekday evening, and he said he could come by for a free estimate within 15 minutes. Mark arrived, did a thorough inspection of my roof and gave me a very reasonable price. He came back the next day and completed the work (replacing about 10 missing roof shingles and removing some moss). He also took before and after pictures to confirm that work. I'm always hesitant working with contractors for fear of being upsold, but Mark was honest and didn't try to pressure or sell anything extra that I didn't need. When it is time for a new roof, I am absolutely coming back to Mark. Would certainly recommend.

Needed a roof repair after squirrels got in. Got the run around from another roofer for two weeks. Called Alter Phase and the job was done in 24 hours. Tim sent before, during and after photos. Quick and courteous. Best repairman I've dealt with in a while!

Incredible service! Outstanding professionalism from the second Mark and his crew arrived until the job was done! Highly recommend. Excellent quality and excellent experience. Switched out our old roof in just one day.

Thank you Mark . Mark is very polite and responsible, job was done quick and professional, with a warranty.
