About Us

Duncan Roofing

is a trusted, locally owned roofing company proudly serving the Tampa Bay area. 

Our foundation is built on decades of hands-on experience—dating back to 1992, when our owner worked roofing jobs to pay for college at the University of South Florida. That same work ethic and attention to detail still guide everything we do today.
When you call Duncan Roofing, you’re not handed off to a salesperson—you work directly with an experienced roofer who will personally walk you through every step of the process, from inspection to completion. We understand that your home is one of your biggest investments, and we take that responsibility seriously.

By keeping our overhead low, we’re able to offer competitive pricing without cutting corners—passing real savings on to our customers while delivering dependable, high-quality results. If you’re looking for an honest, reliable roofer who puts your needs first, Duncan Roofing is here to help.

Working directly with the roofer instead of a salesperson changes more than the interaction, it changes the estimate itself. A salesperson without hands-on roofing experience is more likely to miss underlying issues, deck rot, poor prior flashing work, ventilation problems, that don’t show up until the job’s already underway, which is where surprise costs usually come from. Getting eyes on the actual roof structure at the estimate stage, rather than just measuring for materials, is part of why the process starts with an experienced roofer rather than a sales rep.

Started roofing to pay for college in 1992 also lines up with one of the more demanding stretches for Tampa Bay roofs. A roof installed in the early-to-mid 90s is now past or approaching the end of its expected lifespan for shingle systems, which means a lot of that early hands-on experience was earned working on roofs that are only now cycling through for replacement, giving three decades of full lifecycle familiarity with how Tampa Bay’s roofing systems actually age rather than just how they’re installed.
