About Us

Who We Are

Titan Roofing and Exteriors is more than a typical roofing company—it represents a culture of dedication, resilience, and camaraderie. Established by a group of visionaries inspired by both their experiences on battlefields and on rooftops, our foundations are rooted firmly in the strong sense of unity and purpose fostered by our collective backgrounds.

The journey of Titan Roofing and Exteriors began with a poignant incident that highlighted the gravity of unity and the necessity of a meaningful mission in life. It was out of this shared experience that our company was conceived. Located in Des Moines, Iowa, we are deeply committed to giving back to our veteran community—a testament to the profound influence of our military roots. Annually, we notably install one to two roofs free of charge for veterans within the Des Moines Metro area, extending our battlefield camaraderie to our community initiatives.

Our related venture, The Titan Project, underlines our ambitions further, focusing on veteran outreach and helping those adjusting back to civilian life. Through these initiatives, we not only provide free roofs but also nurturing environments that sustain and empower.

At Titan Roofing and Exteriors, we cultivate an employment atmosphere akin to the brotherhood experienced during our service times. We believe passionately in offering employment to veterans that provides not just a job, but a career filled with purpose, clear objectives, and substantial goals. Here, work transcends beyond roofing—it’s about engendering a supportive and fulfilling workplace, where veterans reintegrate, thrive, and extend the bonds of brotherhood into their civilian lives.

Leveraging over 50 combined years of expertise in construction and roofing along with substantial military leadership experience, our team unites exceptional management proficiency with rigorous work ethics. This powerful synergy assures that every project we tackle is completed flawlessly, guaranteeing enduring value and customer satisfaction for homeowners and business owners alike. At Titan Roofing, we are dedicated to excellence, innovation, and community—a beacon of veteran entrepreneurship and solidarity.
