Snow Loads, Calculations and Snow
The number, location, spacing and attachment method is dependant on
the "snow load". Snow loads vary with your location, roof design,
seasons, rapid changes in weather and other factors. If you have snow
guards which come off, you need to review the snow load. Unbalanced
Snow Loads and excessive Snow Build-Up can overload roofs. Good

How do Snow Guards work?
SnowGuards can prevent damage or danger caused by avalanching snow and
ice. Snow Guards are attached to the rooftop to allow snow and ice to drop
off in small amounts or melt completely before falling to the ground.
The Glacier snowguards are designed not only for safety, but for a pleasing
while being very cost-effective.
Snow guards are installed on roof surfaces to protect against snow and
ice damage below. It especially important to install snowguards above: entryways,
walkways, and gathering spots; parking lots and drive-through areas;
expensive landscaping; ground mounted mechanicals; on metal roofs; lower roofs; valleys and
crickets; and gutters and roof protrusions, such as plumbing vents.
SNOWGUARD INSTALLATION AND SNOW GUARD MANUFACTURERS RECOMMENDATIONS:
(Please see individual
products for product specific installation).
NOTE: Best Materials is not responsible for determining the structural integrity or live load
capacity of any roof on which Snow Guards will be installed. This shall be done by an licensed architect or engineer.
See Snow Loads & Calculations above.
* All OEM's recommend
(VERY STRONG). But some use
or SB-1800 structural adhesive sealants. SB-1800 cures quicker, but is
not nearly as strong and is more expensive. SB-1800 is the only
material which can be used during cold temperature installations,
and should be seen as s temporary adhesive until weather warms..
SB-190 is strongest with 2000 PSI tensile (vs. 325 psi for
If you use SB-1800 or Clear-25, you will need MORE snowguards to achieve the
same snow holding power as with
If snowguards come loose, it indicates you have not installed
enough Snowguards to sustain the snow load or melting snow
conditions. It is not a failure of the adhesive system or the
snowguards. If you attached using SB-1800, re-attach these with
SB-190 in the Spring / warmer weather.
* Use of adhesive only or adhesive
plus fasteners is satisfactory for some
applications with Glacier snow guards. Glacier recommends
Typical SnowGuard Installation Procedures for
1. The area that the SnowGuard will be installed must be clean
from any surface contamination. Alcohol will clean the area and
will dry quickly. Area must be dry for adhesives to bond properly.
2. Use a pencil to mark the area where the Snow Guard will be
installed, no more than 12" from outside of exterior wall to help
prevent ice dams. At the eaves on most roofs under 6/12 pitches,
two staggered rows of SnowGuards will be sufficient. Over 6/12 pitches, a third
row must be added. If the distance from the roof edge to peak is
greater than thirty feet, no matter the pitch, two additional rows
of SnowGuards should be added. Add Snow Guards to areas over doorways and around
valleys for added protection.
* If unsure about location,
placement, fastening or
number of Snow Guards needed please
Snow Guards technical support.
3. After marks have been made. Test fit the Snow Guard. Then apply
a bead of adhesive to all ribs, edges and flat surfaces on
the entire bottom of Snow Guard. Be sure to apply enough adhesive
to fill all air gaps along the ribs and flat surfaces.
One tube installs about 6-8 Heavy Duty guards and 17 to 20
of the Mini Guards.
4. Press the SnowGuard firmly into place with the shingle ledge
pointed up, above the mark made in step 2. Apply enough pressure
so the adhesive flows into all the holes and around perimeter.
5. OPTIONAL FASTENERS: If specified, install screws through pilot holes of choice in Snow Guard and
metal roof. Screw must penetrate through purlin or support beam
under metal roof panel. For most installations, two screws which
penetrate into the support beam must be used as a minimum.
Installer shall determine proper length, size and number of screws
necessary for required holding strength and torque. Four or more screws help full the metal flat against the Snow Guard and provide even
bonding of the adhesive to the metal
6. Apply an additional small bead of adhesive around the perimeter
of the Snow Guard to seal all edges. Be sure that adhesive came
out of all holes, if not apply adhesive to these areas. Cover the
top of any screws to seal the penetration path.
7. Clean up any excess adhesive sealant with WD-40 (best) or Acetone or
alcohol (caution: solvent materials are very flammable. Also, eye
and skin protection should be used).
8. Allow enough time for the adhesive sealant to fully cure.

initially set after 8 hours and fully cure after 24 hours at 70F
and 50% RH, and can be applied down to -20F. It will set and cure
below 50F, just slower. You will need MORE snowguards when using
SB-1800 as its not as strong as Clear-25.
Glacier Installation Procedures for Mechanical
Installation on Shingles:
- Area that SnowGuard will be installed must be clean from any surface
- Install the first
Snow Guard no more than 12" from outside of exterior wall and 12"
from outside of gable side to prevent ice dams. Determine the
position of the shingle that will cover the shingle ledge by laying
it in position and marking in the center of the lower shingle.
From this mark, measure up no less than 1 (one) inch and no more than
1-¼ (one and a quarter) inch and place a mark, this mark is the top
of the Snow Guard.
- The installer
must determine the proper length, size and number of fasteners or
type of adhesive to
use. The head of the fastener must be even with snow guard, if it
sticks beyond the Snow Guard it could cause the fastener to push
through the shingle.
- Now is the time
to install the first Snow Guard. Position the top of Snow Guard at
the mark made in step 2. Insert fasteners into chosen holes of
Shingle Ledge on uppermost part of Snow Guard. When fastening be
sure that one screw penetrate through a rafter, purlin or structural
- Install the
remainder Snow Guards to this row following the guidelines
discussed. There should be a maximum of 24" between each Snow
Guard horizontally and a maximum of 24" vertically. Stagger the
next row at the midpoint of the Snow Guards below. Continue this
row until reach the other side of roof. At the eaves on most roofs
under 6/12 pitch, two staggered rows will be sufficient. Over 6/12
pitch, a third row must be added. If the distance from the roof
edge to peak is greater than thirty feet, no matter the pitch, two
additional rows should be added at the center of roof. Add Snow
Guards to areas over doorways and around valleys for added
protection. If unsure of amount needed please contact Glacier
- If using screws,
cover top and edge of screw with sealant to further protect from
