Now, you can appreciate the significance of marking the roof earlier.
With precise markings, we know the exact location of each rafter, enabling us to install a hidden hanger at every mark using a 2-inch deck screw.
Unlike nails, which may loosen over time due to the freeze-thaw cycle of winter ice, hidden hangers provide a sleek exterior appearance to the gutter while allowing for ice expansion without causing damage.
By securing the gutter to every rafter, spaced either 16 or 24 inches apart depending on the construction, we ensure stability, allowing ladders to be leaned against it without concern.
However, I recommend wrapping the rails of an aluminum ladder to prevent scratching.
