Retrofit

Retrofit snow guards are for installing on existing roofs. You do not have to remove the slates, tiles, or shingles in order to install these snow guards! There are two general types: ones with notched shanks that slide up underneath the shingle and hook on the shingle nail (Berger, Gough, etc.), and ones with a hooked top that slide over the head of the slates (Mullane, Salvo, etc.).
 
Note: the notched retrofit snow guards have a "reach," which is the maximum distance they will slide under a slate and still hook a nail! 

Measure your slate from the bottom edge to the nail hole in order to determine what reach is required for your particular slate.  Some imported slates have high holes and some longer slates (22 inches long and 24 inches long) may be too long for the snow guards you're looking at. If your reach is too high, use Mullane or Salvo retrofit snowguards! Or custom order Gough retrofit snowguards with extra shank length.


How to determine the reach on your roofing slates when using notched-shank retrofit snowguards.

    Designed to be installed on existing slate roofs. All BRONZE GUARD® products are cast in pure tin bronze, using only virgin metals to assure the highest quality alloy. Slide this snowguard in between two existing slates until the top of the snow guard hooks over the top of the underlying slate. See instructional video below.

    A traditional  spike style snow guard, from a design first patented in 1899. The Model  #100 is historically accurate for period restorations, but is just as  appropriate for new construction or retrofit application on existing  slate roofs. Because of its low profile, this model is more appropriate  for residential usage. The Model #100 is for applications on slate,  shake, and shingle roofs, and is designed to fit between adjacent pieces  of roof material, so that only the casting is visible above the roof  surface.

    [The #100 snowguard has a smaller face than the Mullane #200 Retrofit Snowguard, and is less expensive.]

    Designed to be installed on existing slate roofs. Slide this snowguard in between two existing slates until the top of the snow guard hooks over the top of the underlying slate (see video). This  spike style snow guard is fabricated from the same sheet metal  components as the #100, but the #200 casting is 30% larger than the  #100. Both products are equally strong and effective in their capacity  to hold snow on the roof, but the Model #200 is more appropriate to larger scale buildings, or where the roof material is thicker than usual, such as tile roofing.

    All  BRONZE GUARD® products are cast in pure tin bronze, using only virgin metals to assure the highest quality alloy. The castings are produced  locally by old-world craftsmen using state of the art equipment to assure that each casting is of consistent quality. The final assembly is  done by hand, using only solid copper rivets, so that each finished  product is of uniform quality.

    This snow guard is also available in a standard style for new roof installations.

The superior design of the Pro 100 includes a one inch gusset that reinforces the shoe, which makes this snow guard 5X stronger than traditional residential snow guards. The Pro 100 has been tested to withstand a 300-pound point load at any location when applied to the gusset side of the shoe. Simply insert the slotted bar under the slate or shingle, engage a nail with one of the conveniently placed slots and pull to fully secure the bar (12 1/2 inches maximum reach to nail). This  style snow guard provides fast installation and is ideal for existing applications with slate roofs.

    Mullane 300S-RH copper/bronze retrohook style snowguard for installing on existing roofs. The solid bronze casting eliminates the corrosion problem caused by condensation which is formed inside of closed, pressed copper snow guards. The installation flange can be easily fabricated to any length for any roof application, and is also available with our Retro-Hook.

    18  inches long, 2.5 inches wide, protrudes up from the roof about 2 inches. The half round Model #300 casting is attached to a 20 oz. copper installation base flange by four brass rivets for extreme  durability and snow load bearing capacity. The solid bronze casting is  extremely durable and rugged. Tested at 870 pounds pressure.

    This snowguard has a "reach" of about 13.5 inches. It can slide up underneath the slates 13.5 inches maximum before engaging the top of the underlying slate. So for a typical 24 inch long slate with a 3 inch headlap and a 10.5 inch exposure (13.5 inch unexposed), the snowguard should just have enough reach to slide underneath, slide the length of the unexposed area, and hook over the top of the slate. Shorter slates will leave more of the snowguard exposed. One advantage to this snowguard is that you can install it over the head of slates on random width roofs and still maintain a uniform layout on the snowguards because you don't have to line the snowguards up with the slots.

    Mullane 200CPT retrofit for tile roofs. Designed to be installed on existing tile roofs.


    Snow  guards should be installed where the potential for the sudden sliding of  ice and snow can be hazardous to people or property below. Falling snow  is a life safety issue, and careful consideration of liability issues  should be part of a carefully designed roof system in all areas prone to  winter snow and ice.

    All BRONZE GUARD® products are cast in pure  tin bronze, using only virgin metals to assure the highest quality  alloy. The castings are produced locally by old-world craftsmen using  state of the art equipment to assure that each casting is of consistent  quality. The final assembly is done by hand, using only solid copper  rivets, so that each finished product is of uniform quality.
