Wilmington, Delaware has many properties we would consider historical, with Slate Roofs and Built-In Gutters. The Built-In Gutters are usually on their last years of service and the old Terne Coated Steel (known as ?tin?) linings are in need of replacement. Although not well known, the reason many of the old buildings have the ?tin? cladding on the guttering is not only that the copper was more expensive, but that the sulfur dioxide emissions from the chimneys would concentrate and prematurely erode the copper claddings. Since we are not burning anthracite coal for heat any longer (speaking for most of us), the sulfur degradation issue is no longer a problem. Copper is the material of choice for most of the linings we do. The added beauty of the cladding lends a certain ambiance to the already historic feel of many homes in Wilmington, DE.

Just another job, this one in Wilmington, Delaware where existing were Peach Bottom Slates. These are the finest Slates in the world. This roof was installed in 1932 and the Slates were like brand new. Hard, tinked with a ring sound and we did not break even one on the job of removing and re-installing them. Also take notice of the Berger #100 Copper Snow Guards for the finishing touch.
