Never Clean Your Gutters AgainGutter Guard Installation in Marshalltown, IA

Metal moves, and fasteners have to allow it

An aluminium gutter run gets hot in summer sun and cold on a January night, and it changes length as it does. Over a long run the movement is measurable, enough that a system fastened rigidly at both ends and every point between will fight itself. The usual outcomes are elongated screw holes, a slow loosening at the fixings, and buckling where the metal had nowhere to go. Adding a guard adds another layer of metal with its own expansion, fixed to the first. Good installations account for this with slotted fixings that allow slight movement, expansion joints on long runs, and sensible fastener spacing rather than the maximum number of screws that will fit. It is one of the differences between a job that looks identical on day one and diverges after five summers. If you are looking at two quotes and one specifies how the guard is fastened while the other says the product name, the first is telling you something.
