(I posted this also as a reply. It's the same thing.)Question--I recently had a standing seam metal roof installed on my garage. The garage is a stand-alone building. The old roof was 80 years old, also metal, and had a drip edge overhanging the side of the garage where the rain goes to. The roof slopes about 20 degrees. The new roof has no overhang. Therefore, water cascades down the side of the garage, inundating the brick and mortar of the exterior wall. The installer came back to look after I complained and he told me he did everything correctly. He told me that a big wind would come and tear and overhang off. However, the old overhang extended down 2 or 3 inches. It was basically a continuation of the roof metal folded down. It kept water off the side of the building. The fellow who came to answer my compaint told me that he would install a gutter for me--at added expense, of course. But it seems to me that a proper intallation of the roof includes an overhang, just as there was before. Am I incorrect to think this? Many thanks for your wisdom.

Well the building code calls for a drip edge to be installed on all roof coverings. Certainly if you had a zero over hang on the garage, he should have paid attention to how the water was handled on the original roof. Generally on zero over hang conditions with metal, they incorporate a one piece gutter and drip edge that is up under the roof covering. Certainly if you do nothing it will deteriorate the side walls eespecially in colder climates.
