We recently had to have our roof replaced.After getting several quotes we decided on MGS Construction,Our salesman Al Guevara was outstanding! He was the only rep to stay in contact with us to answer any questions we had.We had to have a complete roof replacement including all decking.on the day of the installation Dean the foreman and his crew of men and woman showed up before dawn ready to go..Throughout the day Dean kept us informed of each step in the process.the crew was fantastic like a well oiled machine,they never stopped working. Al came bye a couple times as well. Dean and his crew were able to complete the entire job in one day!Everything was picked up and cleaned like they were never here. We would highly recommend Al and MGS Construction.

We used MGS for our roof replacement. Al Guevara came out to give us a quote; he was very knowledgeable and professional. He emailed the written quote later that day and was very responsive when we had questions. The crew showed up on time and worked very efficiently. Al checked in on-site during the job and even texted us progress photos to let us know no roof boards needed replacing, which we really appreciated. From start to finish, the job was done in 6 hours. Also, a little detail that I liked is that the pipe boots chosen blend in great with the GAF oyster gray shingles. Would highly recommend Al and MGS.

I contacted MGS for an estimate on roofing replacement because of the large number of great reviews on line; and they did not disappoint. My point of contact Mike was both knowledgeable and professional and guided the whole process through its successful completion. The crew did an outstanding job leaving the worksite as iclean as if they had not been here. I would highly recommend MGS to anyone looking to have their roofing replaced.
