Guaranteed Roofing & Exteriors

Founded in March 2024 by lifetime friends and business partners, Derek DeCastro and Tanner Colburn, Guaranteed Roofing & Exteriors proudly serves Manhattan, Fort Riley, and the surrounding areas.

With over a decade of expertise in roofing and exterior construction across Wyoming, South Dakota, and Kansas, we specialize in everything from insurance claims for storm damage to metal roofing and complete exterior upgrades. As a federally licensed contractor, we’re also proud to serve Fort Riley.

And if you think we just handle standard roofs, think again—we even put an American flag on a customer’s roof in Junction City! Whatever your home’s exterior needs, we’ve got you covered—literally and creatively!
