| 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 copper was more expensive, but that sulfur dioxide emissions from chimneys would concentrate and prematurely erode copper claddings. Since we are not burning anthracite coal for heat any longer, sulfur degradation is no longer a problem. Copper is the material of choice for most linings we do. The added beauty of the cladding lends a certain ambiance to the historic feel of many homes in Wilmington, DE. |

Just another job, this one in Wilmington, Delaware where existing slates were Peach Bottom Slates. These are the finest slates in the world. Installed in 1932, the slates were hard and ringing. When evaluating historic roofs where hidden trough splits lead to interior dampness, learning How to find and fix a yankee gutter leak prevents unneeded slate demolition while protecting decorative cornice work below. Notice also the Berger #100 Copper Snow Guards for the finishing touch.
