Abstract
Built-in gutters are a frequently mis-constructed roof component. The basic principles of thermal movement, as well as their direct impact on material selection, appear to be misunderstood by both design professionals and contractors. Dubious details contained in some of the industry's standard reference manuals do not help the matter. Recommendations for proper built-in gutter design and detailing will be made, including a discussion of the stresses imposed upon built-in gutter liners under thermal load, seam selection, rivet selection and spacing, expansion joints, and layout. Common misconceptions concerning gutter design, having to do with metal temper and gauge, will also be examined.
