Seamless Building Systems did a complete reroof of our 11,000 sq. ft. office building which consisted of both sloped shingled roof and flat roof. They did a cedar tear-off and reroof and replaced our rubber roof with TPO. They did a great job to efficiently get the job completed and did a wonderful job cleaning up the worksite after completion. Great communication from quoting the project to project competition. A week later we had a 11+ inch rain storm and no leaks.

I have use SBS for a number of jobs varying from roof coatings, roof replacements, aluminum trim, and emergency repairs. Each time the experience has been great. Their skilled craftsman are able to problem solve any unforseen issues and provide a quality end product. Their attention to details such as job site cleanliness and project esthetic are top tier. I will continue to use SBS and would recommend them to others

We have had many great experiences when working with Seamless Building Systems, LLC. on both commercial and residential projects. Chris, Jason and Brandon have all been great help when the time to collaborate on projects has been needed. From planning to completion, their combined knowledge on all aspects of roofing, siding and construction has been enlightening on how to get the best results on many of our challenging projects. Workmanship and any project follow ups have always been handled and promptly and properly. Great organization to forge a relationship with as a property owner.
