Roof raking helps clear snowfall from your roof and, in turn, you hope that this prevents ice dams. But can roof raking actually cause them? Generally, no, it cannot. But you should note that while, in some cases, you might successfully prevent ice dams from forming near the edge of your roof by keeping it cleared with a roof rake, they could still form higher up on the roof, where you are unable to reach. This may leave you wondering: Does roof raking prevent ice dams? While it is not a 100% guaranteed way to prevent them, it does help.

Whether or not an annual snow removal contract is worth it depends mainly on location. If you live in an area with frequent heavy snowfall, a yearly contract could be better than paying per clearing. If you live in an area where it only snows a few times a year, paying per snowstorm may be a better option.

When starting the engine, you typically leave the choke on a snowblower in the "choke" or "closed" position. After starting, let the engine run for a few minutes to warm up. Then, gradually open the choke, moving it to the "open" or "run" position, allowing more air into the engine and transitioning to a normal fuel-air mixture. The exact duration varies based on the snowblower model and ambient temperature, but as a general rule, you should open the choke once the engine has stabilized and runs smoothly, typically within a few minutes.

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.
