Building Trust, One Roof at a Time

At Delmar Roofing and Siding, we believe in doing more than installing roofs; we build trust, reliability, and long-term protection for homes and businesses across Delaware. Founded on principles of honesty, craftsmanship, and service, our team has proudly served Magnolia, Dover, and Milford for over 35 years.

We started small, working with local homeowners who needed dependable roofing after seasonal storms. Over time, our dedication to doing things right, never cutting corners, and always showing up, earned us the reputation of a company people could count on. Today, that same commitment drives every project we take on.

We’re licensed, bonded, and insured, and we’re proud to be certified by leading manufacturers like Owens Corning, GAF, and CertainTeed. From roofing to siding, gutters, and windows, we offer complete exterior solutions under one trusted name.

Unlike large corporate companies, we treat every client like a neighbor, not a number. Our anti-corporate approach means transparent pricing, clear communication, and a personal touch that makes the experience straightforward and stress-free.

Whether we’re helping a homeowner replace a storm-damaged roof or upgrading a commercial property with energy-efficient siding, we bring the same level of care and professionalism every time. When you choose Delmar Roofing and Siding, you’re choosing decades of experience, strong warranties, and a promise to always stand behind our work.
