Snow guards

Duchesne snow guards are rooftop devices that help prevent damage caused by avalanching snow and ice. They can be used on nearly every kind of steel roofing as well as on asphalt shingle, wood shake and synthetic slate roofs.

Snow guards are available in two styles: tube-type and individual. The tube-type snowguard is suitable for both residential and commercial use. It provides a greater level of protection than the individual snow guard, which is more discreet and used mainly for residential buildings.

Please consult an expert to determine the snow guard model required and the proper installation mode depending on your geographical location, climatic conditions, the bearing capacity of the roof, slope and characteristics of the sub-structure.

The set includes :

(A) Brackets, natural or painted G90 galvanized steel (12 gauge - 0.109") with one, two or three 1¼" diameter holes

(B) Plastic protectors for each hole

(C) 7 metal/wood screws (#14 x 2" ) with neoprene washers and anti corrosion coating1 per bracket. Note: The 1-hole bracket comes with 6 screws

(D) Natural or painted Galvalume tubing, 1/16" thick x 1" wide x 4' long with a reduced 3" portion

(E) Protective caps (6 / box of tubes). The quantity of tubing required is calculated by adding 10% to the length of the roof to be covered, taking the overlap between two sections into account, divided by 4 (the length of the tubing). Multiply by 2 or 3 if using two-hole or thee-hole brackets. The number of brackets required is calculated by taking the length of the roof to be covered and dividing it by the spacing between two brackets. Add one more for each section of roof to be covered.

The set includes :

(Ai) Snow guard, natural or painted2 G90 galvanized steel (12 gauge - 0.109") with a central opening and 90° angle

(Bi) 3 metal/wood screws (#14 x 2" ) with neoprene washers

Snow guard features:

  • Fast and easy to install
  • Extremely durable
  • Aesthetically designed to complement your roofing
  • Available natural finish or in a wide range of colours
  • Manufactured from G90 galvanized steel

Snow guard benefits:

  • Help keep snow and ice from avalanching off the roof all at once thereby protecting people, property and landscaping below.
  • Prevent snow build-up in the gutters.
Before you start your project:

The snow guards must be securely fastened to a structural member of the roof. You need to knowthe features and layout of your roof structure in order to be able to properly attach the guards.
The minimum fastening depth required for:
- Wood: 3/4" (19 mm)
- Steel: .049" (1.25 mm)
Depending on the roof's features and the region in which the snow guards will be installed, a different anchoring systemmay be required.

 Installation instructions - Tube-type snow guard
  1. Measure a distance of approximately 1.5 feet from the edge of the roof and mark with chalk or string
  2. To ensure a watertight seal around the screw holes, apply a strip of butyl tape (1/8" x 1") under each bracket
  3. Use the screws (C) to fasten the first bracket (A). Repeat for all the holes
  4. Fasten the remaining brackets (A) in the same way until one section has been completed
  5. Insert tubing (D) through the bracket holes of the finished section. Make sure the plastic protectors (B) are securely in place around each hole before inserting the tubing
  6. Connect two sections by inserting the narrow end of the tubing into the female end of a second line of tubing
  7. Repeat steps 3 to 6 until the desired length is covered
  8. Cut excess tubing as necessary prior to completing the final section
  9. Press the protective caps (E) over the each end of the fixture

Please refer to the «Tube-type snow guard» section see what is included in the set.

 Installation instructions - Individual snow guard
  1. Measure a length of approximately 1.5 feet from the edge of the roof and mark with chalk or string
  2. To ensure a watertight seal around the screw holes, apply a strip of butyl tape (1/8" x 1") under each bracket
  3. Use the screws (Bi) to fasten the first bracket (Ai). Repeat for all the holes
  4. Install one snow guard per linear foot.
  5. Install the recommended number of snow guards for maximum efficiency:
    • For a pitch not steeper than 4/12, one row is sufficient
    • For a pitch steeper than 4/12, two rows arranged in a staggered pattern is recommended (Fig. 5). A spacing of 2 feet is required between rows
