With the significant availability of contractors who own seamless gutter machines, there is rarely ever a reason to use sectional pieces of gutters.
They Will Fail at the additional joints, both from the gutter sealant becoming aged and brittle and also from expansion and contraction.
I have to take a picture later today, to show how the melting snow does not go into the covered gutters, not the master-shield brand, but the amount of icicles is amazing, unless it warmed up too much and they melted or got knocked off by the home owner.
