An ice dam is formed when melted snow refreezes at the edge of the roof.  If left untreated, ice dams can cause a lot of damage to the exterior and interior of your house.  So, we thought we would discuss in this article where the common locations for ice dams to form are, so that you, the homeowner, knows what to look out for.  ​

Snow stop guards are rooftop devices that help snow and ice to drop off in tiny bits or allow ice and snow to melt completely before falling to the ground.  Snow guards help prevent a sudden release of ice and snow from the roof which is known as a roof avalanche. 

Snow and ice can slide off your roof and can weigh hundreds of pounds, just depending on the size of your roof.  And, a snow avalanche can cause a lot of damage to your landscaping, gutters, plumbing vents, skylights, people, pets and cars.  Snow guards can prevent a roof avalanche on metal roofs, and they have been around for hundreds of years. 

​Historically, snow stop guards are used on slate, tile and metal roofs.  They are necessary to help stop the fast release of winter snow.
