I just recently had my roof replaced and my chimney fixed, and this company has been top-notch from start to finish. I am very pleased with their customer service staff. Jonathan, Ileana and owners were all very responsive to my needs and questions The workers were super nice and very efficient, the cleanup afterwards was impressive. Put all deck furniture and flower pots back as it was. The roof looks amazing and the chimney cap looks better than original one I had. Highly recommend this company.

We recently had Magnum install a new roof for us. This is the second roof we have had done by them as our previous home we used them as well. Excellent workmanship and competitive pricing. Roof replaced in one day with thorough cleanup and followup inspection the next day. Overall very pleased and would highly recommend!

There are not positive enough words to say how pleased I was at the service of Magnum Roofing!
They gave me a quote, fixed the damaged area from Ice Damming, then added two roof vents closed off the Skylight areas, cleaned up and disappeared. An outstanding job done without a trace that they had been there except for a fantastic roof!
Plus, and this is the bonus…I felt that the price was a reasonable amount for the work they did!
So, I Highly Recommend Magnam Roofing! I have said that to my entire Subdivision!

They were very patient and accommodating as a row of 6 townhouse owners tried to coordinate to get the roof all done. When finally, several months later it happened, they honored their commitments and got the job done expediently. It looks good and was done at a very reasonable price. When there were issues with some clean up remaining, they promptly returned to address our concerns.

We were dealing with recurring roof leak issues at our condo and feeling increasingly anxious about the integrity of our roof with winter fast approaching. The uncertainty around the condition of the seal and the risk of further damage made the situation especially stressful.
Enter the team from Magnum Roofing—they were phenomenal from start to finish. Communications with Pat and Jonathan were consistently timely, informative, and above all, thoughtful. He took the time to explain everything clearly and made us feel truly supported throughout the process.
Not only did Magnum take swift action to address the problem before weather conditions would make the work unsafe, but their professionalism and care gave our family enormous peace of mind during a very challenging time. We felt looked after, and that made all the difference.
We would wholeheartedly recommend Magnum to anyone looking for roofing support that’s not just skilled, but also caring, honest, and deeply experienced. Thank you, Magnum!

I had a fantastic experience with Magnum Roofing. Steve, was amazing. Always quick to respond and made himself available whenever I had questions. His crew was just as impressive: fast, thorough, and professional. They replaced my entire roof in just one day and left everything spotless afterward. The quality of the work was excellent. I highly recommend Steve and Crew to anyone looking for reliable, local roofing services.
Steve, Jonathan and crew at Magnum Roofing are the best. Thank you.

We were pleased with several aspects of Magnum's work. You provided lots of options for shingle types and colors. You worked with us to select the best date(s) for installation. The roofers did excellent work and cleaned up the yard and driveway. We are pleased with the warranty.
