For this metal slate roof installation in Middletown, DE, we replaced the home's existing asphalt shingles. This home. built in 1830, faces strong winds often enough to rip up some of the shingles. This has lead to performance decline, leaks, and a drop in curb appeal. The new metal slate roof works perfectly with the authentic, historic look these homeowners were going for. Our steel slate roofs have an emphasis on extreme durability, energy efficiency, and long-lasting, gorgeous designs.
