Get matched with top roof ice and snow removal pros in Fairmead, CA

Generally, snow removal from a roof should occur once over six inches of snow accumulates, especially if you notice that ice dams have formed. Without ice dams, you can let the snow accumulation hit 12 inches before removing it. However, the amount of snow that is too much for your roof also depends on the sturdiness of your roof and the compactness of the snow. If your roof needs maintenance or has structural issues, it’s best not to let the snow accumulate too much for fear of collapsing.

Most roofs can take quite a bit of weight from snow, but their ability to handle heavy snow is not unlimited. Most roofs can handle about 20 pounds per cubic foot of fresh snow. Ice, ice dams, and other factors can contribute to dangerous roof weight. Newer roofs, sloped roofs, and those that have more support can hold more snow than older roofs, flat roofs, and roofs with widely spaced beams. To figure out how much snow your roof can hold, you will need to contact a professional roofing contractor to calculate the maximum snow load for your specific roof.

If a big freeze catches you by surprise and you don’t have any deicer to hand, you can reduce the chance of taking a tumble by laying gritty, anti-slip materials. Some natural, readily-available options that don’t melt ice but offer traction underfoot include sand, wood shavings, kitty litter, and fireplace ash.

While removing every snowflake from your roof is unnecessary, you should remove a significant buildup of snow. Since snow is wet and heavy, it can easily cause damage to your roof, which can lead to needing costly repairs. 

Additionally, when the snow melts but has nowhere to go and refreezes, it can create an ice dam, causing mold concerns due to water leaking into your attic and ceiling. For these reasons, it’s best to hire a snow removal professional to clear heavy snowfall from your roof as soon as possible.
