Snow Guard Safety Guidelines
Snow guards are devices that
are attached to the roof structure in order to uniformly retain and
hold snow in place on the roof area. The snow guards need to be
applied in sufficient quantity according to a prescribed pattern in
order to be effective. Snow Guards are intended to prevent snow
movement and provide for the controlled melt and breakdown of the
snow mass into smaller sections. Snow guard placement will vary from
region to region and will be influenced by roof pitch, the lengths
of roof runs and roof features. Local installation customs may not
be the best guide for placement. Snow guards
should never be placed beyond the bearing wall on an extended roof
section. This can result in ice damming and cause structural damage.
Safety Hazards
Roofing
can be hazardous! Serious injury or fatality can result from falls
or electrocution from contacting overhead wires. Observe ladder
safety rules for load, positioning and security.
Please
make sure all roof surfaces are dry and clean before working.
Avoid working in excessive heat, high wind or when there is a
threat of lightning. Never work alone.
Do not
allow material to be unsecured on the roof. Falling objects are
dangerous.
Don't Put Dissimilar Metals
Together
Galvanic corrosion will occur
when dissimilar metals are in contact in the presence of an
electrolyte. Water is an
electrolyte. Water that flows over copper becomes electronegative
and will cause corrosion of aluminum or steel. Copper, brass or
stainless steel fasteners or nails must be used with copper or brass
applications. Make sure rivets are solid copper; do not use copper
plated steel rivets in copper or brass assembly. Do not use aluminum
or galvanized nails to secure any copper products. Corrosion will be
more rapid in the presence of salts such as ocean coastal areas or
chlorinated water, acid rain, and polluted industrial atmospheres.
