Mullane 100S Snow Guards

Mullane 100S standard nail application snow guards are designed to be installed on slate and asphalt shingle roofs by nail application during the installation of the roofing. All BRONZE GUARD® products are cast in pure tin bronze, using only virgin metals to assure the highest quality alloy. The shoe is cast bronze and the strap is 24-ounce cold-rolled copper.

See side-by-side photos comparing the AS to the NA models. The NA is longer and sits higher on the roof with more space between the shoe and the strap for thicker shingles and slates (maximum 3/8" slate, tile, or shingle thickness). 

The AS is shorter and the shoe is closer to the strap, which makes it more suitable for thinner roofing such as asphalt shingles. Check the CAD drawings below to make sure the dimensions work for your shingles.

This is a traditional spike style snow guard from a design first patented in 1899. 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. 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. 

$19.50 each.

This snow guard is also available in a retrohook style for installation on existing slate roofs. The #100 snow guard has a smaller shoe than the #200, and is less expensive. View the #200.
