About Us

Quality Craftsmanship
and Integrity Since 2014.

Titan Exteriors opened in June of 2014. Owner John Allman had previously worked in hospitality and saw a need for better service and quality in the contracting industry. John and his team believe that integrity is essential and they focus on this as well as high levels of customer service in all their projects.

Titan is proud to offer only products that have a 50-year or lifetime warranty as this provides peace of mind to their customers. They also pride themselves on providing top-notch education to their customers so they can make educated decisions about their projects. 

Titan replaces approximately 200-300 roofs and 40-50 full re-sides per year. They are a full exterior company and know how each piece of a project works with the other components to provide the ultimate shield against weather infiltration. 

Each Titan employee is local and they all take pride in bettering the homes in their community. The team at Titan truly cares about each of their customers and puts their heart and soul into each project.
