Gal, Rose, Jose and the rest of the crew were amazing. They gave me an up front estimate and delivered on all promises. Gal took the time to inspect the attic and determined there was no existing plywood on the roof just four layers of old shingles including the original wood shake. Alpha One’s estimate was what the job actually cost because of Gal’s added care while inspecting and preparing the estimate. Great job all around.

This company is top notch. They were wonderful. On time clean did a very good job. They found some damage on my roof. I kid at what had happened and ask them if they can fix it and they did. Cost was a little extra and they did a great job. I would hire them again and would I would definitely recommend them

Adam did an outstanding job on my in-laws’ roof! From the very beginning, he was professional, responsive, and took the time to explain the process clearly. His crew showed up on time, worked efficiently, and kept everything clean throughout the project. The quality of the workmanship is excellent—the roof looks great and gives us peace of mind knowing it was done right.
What really stood out was Adam’s honesty and attention to detail. He treated the project like it was his own home, and my in-laws felt comfortable and taken care of every step of the way. It’s rare to find someone this reliable and trustworthy in the industry.
Highly recommend Adam if you need a roofer who delivers top-notch results and excellent service!

Natanl was on time and made sure after fixing appliance that it worked. He was very knowledgeable and cleaned everything up before he left. He was a pleasure to work with because he answered all the questions I had. I would definitely use this company again for any future problems
