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!

I highly recommend Oscar and his team. We had a significant roof leak and major rain was about to start in two days. He was able in a professional manner to point out unequivocally the causes of the leakages. They were fixed professionally in time and the recent rain proved that it was successful. The price was appropriate, and in fact we would have saved money by calling Oscar right away instead of paying someone to just patch it up which did not fix the issue at all. Next time I call Oscar first.

I recently hired Alpha One Construction for a new roofinstallation, and I couldn't be more satisfied. Their team was professional, efficient, and completed the project on time. The quality of workmanship is outstanding, and they ensured everything was clean and tidy before leaving. The new roof looks fantastic and has greatly improved the overall look of my home. I highly recommend Alpha One Construction for anyone in need of roofing services.
