Before Snap-Lock, every gutter in the United
States was attached to the fascia with a nails,
spikes or screws. When holes were made into
the back of the gutter with these obsolete
fasteners - water could be unintentionally
introduced into the fascia area. The holes
in the wood fascia - into which these attachments
were originally driven were constantly wet.
Eventually the strength of each fastener would
become compromised by the deadly combination
of wetness, weakness, rot and weight (of ice
and snow in the gutter). In time, without
intervention, every gutter will come loose
and eventually fall off the house.
