Denver Roofing: Article About What To Know About Snow
During winter, homeowners want to stay warm when it's cold outside. As the snowflakes pile higher outside the window, some residents may start to get concerned about the snow building up on the roof. How much snow is too much? How can homeowners safely remove snow from the roof without causing any damage? What signs should homeowners look for to avoid costly repairs? Residents in the Denver area can rely on a Denver roofing specialist to provide answers to these questions and more.
Most snow will quickly melt or slide off roofs, but weather conditions sometimes allow snow to accumulate and remain on rooftops. The amount of snow a roof can safely handle depends on several factors. A smooth, steep roof allows snow to slide off rather than build up. A roof that is flat or only slightly pitched holds more snow and is at higher risk for damage as snow accumulates. Rafters that are closely spaced provide more support for rooftops, reinforcing the weight more evenly. When rafters are spaced far apart, the roof is weaker and can't support as much weight. Rooftops that are sheltered from the wind distribute snow more evenly than those in direct currents. If large drifts develop, a roof can fail. Interior damage such as cracks or termite damage can also contribute to roof failure.

Although there's no set rule for the height or weight of snow any roof can support without damage, there are signs of weakness. The attic is the first place to start looking for impending damage. Homeowners should inspect rafters and bracing for cracks. Rafters should not bend under the weight of the snow; if they do, it's cause for concern. Cracking and popping sounds are also indicators that the roof may fail. Another sign to look for is jammed doors inside the home at either end of the house. This indicates that the frame has moved, so a structural engineer should be consulted.
Homeowners can remove excess snow from the roof or call a professional to remove the snow. A roof rake can be used to push snowdrifts from overloaded areas. Professionals will carefully rake the snow over the edge without pulling on any roofing material, satellite dishes, chimneys or other attached structures. When climbing ladders, roofing specialists use caution and wear slip resistant footwear and proper attire. To avoid injury, homeowners should always follow the manufacturer's directions when using a roof rake. It's important to only use approved extension rods and ensure a proper fit before use.
