![]() ![]() While the color match is ideal, it can be unnecessary later. These devices must be replaced multiple times before the roof life expires.Īlso, several devices rely on dyes or air-dried paint to color match architectural roofs. Many of the snow guards on the market today are made of corrosive metals or plastic and have nowhere near the intended service life. ![]() ![]() These material types should be considered when selecting your snow retention system. In most conditions, galvalume®-coated steel has a performance life expectancy of 40 years or longer.Īluminum is projected to have a longer service life than steel. This effect exposes the bare metal to corrosion. In addition, the fastenings should not produce scoring, which could result in roof material breakage or premature corrosion.Īlso, screws with a "cup point" pierce carbon steel panels' delicate protective metal coatings. Furthermore, the fastening should not damage the protective metallic coatings on steel panels. Mechanically attached snow guards should be secured with fastening methods that do not pierce the roof's weathering membrane. The snow guard Fastenings should be thoroughly examined to avoid the destruction of the rooftop warranties. Also, independent studies have shown that metal roofs endure 40 years or more than other roofing materials. Plastic and cast aluminum grow brittle over time and crack or fracture.Īccording to the Metal Construction Association, snow guards for metal roofs should be non-corrosive metal. Aluminum, stainless steel, and brass roofing systems will last as long as or longer than the metal roof itself. However, extruded aluminum, stainless steel, or brass (for copper roofing) systems are the best choices. Material options include plastic, extruded aluminum, stainless steel, brass, and cast aluminum. ![]() However, snow guards with incompatible or fewer quality materials can't serve this long. Therefore, they should have the same service life and durability as the roof. Snow guards are regarded as a life/safety product.

However, with dozens of snow guard suppliers claiming that their product is the best, it can be daunting to know the best snow guard for your roof. Besides that, snow guards protect homeowners from potential liability or personal injury, or death.Įmphatically, the importance of snow guards is to store snow until it can safely depart the roof. They secure metal roofs from rooftop avalanches and protect a building from damages such as the landscape, gutters, skylight, and more. These devices are also known as snow stops or snow rails. Snow guards are designed to prevent snow from slipping off roofs unexpectedly. This effect can result in roof avalanche, destruction of property, or danger to people below the roof. Snow accumulation on a roof generates sliding forces which can cause the snow to fall suddenly. In many parts of the country, snow and ice accumulation on a pitched metal roof poses a problem. ![]()
