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.
Expansion, Contraction, & Ventilation...
Another problem long associated with gutters
and gutter attachment disappears when using
Snap-Lock. Most homeowners would be surprised
to learn that a long gutter will actually
grow and shrink an inch or more as temperatures
vary. This wreaks havoc on fasteners - causing
them to weaken and come loose. Gutters unable
to expand and contract because they are
“pinned” down will buckle and “pucker” between
adjacent fasteners. Snap-Lock allows gutters
to expand and contract normally. Additionally,
corner and endcap seams are not stressed
by movement and don’t develop leaks. Finally,
Snap-Lock is the only product that provides
ventilation behind the gutter. Condensation
can lead to black mold growth and accelerated
rot of the fascia board. |
