  Please exercise caution when considering this company. My experience was that the work was performed in a highly unprofessional manner, and despite my attempts to bring errors to their attention, they declined to return and rectify them. Following several follow-up requests, I was informed that a correction was scheduled, but this never materialized. Ultimately, I ceased my efforts. I now regret having paid them before the work was completed to a satisfactory standard, as I believe this would have provided a stronger incentive for them to return and address the concerns I raised.

  Hello, we are very sorry about the confusion with regarding this. Unfortunately due to miscommunication you were wrongfully called as this was for another customer whom had also sent a bank check. We apologize that this caused you to feel that we are not a legit company. As you are aware we do not even ask or require a deposit for any work we do until the project has been completed. We can assure you that we are not out to steal money from any of our clients. We are very happy to know that you were happy with our service and your roof installation. Once again we are sending our sincerest apologies for this miscommunication.

  The team was friendly and very thorough with the roofing job I asked them to perform. I’m planning on hiring them again and will recommend them to my friends. They were professional, organized and good guys.

  I couldn’t be happier with my roof replacement by MGS Construction. I worked with Al Guevara to determine the best solution for my home, and he was incredibly helpful throughout the planning and quoting process. I ultimately chose MGS …

  When shopping around MGS gave great value and communication. They were able to do the job while I was busy at work and made the whole process very easy for a much better price than I could find elsewhere. Highly recommend.

  Al gave us specific detail on how the job was going to go. Everything he said was right on target. The crew was phenomenal making sure the job went smooth. Also making sure none of our plants were harmed when taking the old roof off. Clean up was also excellent no debris could be found after the job was finished. The crew was very courteous and made sure the job was finished in one day

  Job well done. My point of contact, Mike, did an outstanding job by providing client-facing service from beginning to end. MSG offered a competitive price then followed through with an exemplary product. I cannot recommend this company enough.

  MGS replaced my roof. After my initial call to MGS, Mike called me within 10 minutes. After he came on site he provided an estimate before he left my house. The price was very competitive and the work was completed on time as promised. The crew was excellent and cleaned up after the job was done. I highly recommend MGS!

  I knew I wanted a GAF roof so went through their website and picked the three highest rated installers. I got quotes of $21K, $27.5K and $47.5K. The low bidder did not include attic venting so we went with MGS Construction. Al Guevara …

  Hi, Dave. Thanks so much for taking the time to write us a review.

Weather can have a significant impact on your roof, making it essential to understand how different conditions affect its integrity. Local roofers are your best allies in maintaining a strong and durable roof throughout the year. Sun exposure can cause roofing materials to become brittle and crack, especially asphalt shingles. Local roofers can help by conducting regular inspections and applying protective coatings to reflect harmful UV rays. Heavy rainfall can lead to leaks and water damage, which can compromise your home's interior and promote mold growth. Local roofers can identify weak spots and seal them to prevent moisture intrusion. Strong winds can lift or tear off shingles, exposing your roof to further damage. Regular inspections can help secure loose shingles and ensure your roof withstands windstorms. Winter brings its own challenges with snow and ice, adding weight and causing potential structural damage. Local roofers can provide solutions to prevent these issues.
